1. 需要實現(xiàn)的功能

照片小圖排列顯示，點擊任意一張圖片可以切換成大圖。
實現(xiàn)思路：根視圖中顯示小圖，用滾動視圖控制器來顯示全部圖片；另一個視圖控制器來顯示大圖，用一個導(dǎo)航控制器來管理這兩個視圖的前進(jìn)后退關(guān)系。

2. 實現(xiàn)小圖排列顯示

首先還是刪除ViewController文件，在AppDelegate.m中添加代碼，創(chuàng)建window和導(dǎo)航控制器：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #008400}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p7 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #bb2ca2}span.s1 {font-variant-ligatures: no-common-ligatures}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s4 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s5 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s6 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s7 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s8 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    //導(dǎo)航控制器框架結(jié)構(gòu)
    self.window=[[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
    UINavigationController* nav=[[UINavigationController alloc]initWithRootViewController:[[VCRoot alloc]init]];
    
    self.window.rootViewController=nav;
    [self.window makeKeyAndVisible];
    
    
    
    return YES;
}

</br>
之后創(chuàng)建一個新文件VCRoot，在VCRoot.m中設(shè)置導(dǎo)航控制器屬性，創(chuàng)建滾動視圖，打開并設(shè)置點擊手勢交互事件：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #008400}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}span.s1 {font-variant-ligatures: no-common-ligatures}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s4 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s5 {font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s6 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s7 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s8 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}span.s9 {font-variant-ligatures: no-common-ligatures; color: #272ad8}span.s10 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s11 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s12 {font-variant-ligatures: no-common-ligatures; color: #008400}span.s13 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures; color: #008400}

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    
    
    self.title=@"照片墻";
    self.navigationController.navigationBar.translucent=NO;
    self.navigationController.navigationBar.barTintColor=[UIColor yellowColor];
    
    
    
    //滾動視圖
    UIScrollView* sv=[[UIScrollView alloc]init];
    sv.frame=CGRectMake(5, 10, 300, 400);
    //畫布大小
    sv.contentSize=CGSizeMake(300, 480*1.5);
    //隱藏右側(cè)滾動條
    sv.showsVerticalScrollIndicator=NO;
    
    
    //打開交互事件
    sv.userInteractionEnabled=YES;
    self.view.backgroundColor=[UIColor whiteColor];
    
    for (int i=0; i<15; i++) {
        NSString* strName=[NSString stringWithFormat:@"%d.jpg",i+1];
        UIImage* image=[UIImage imageNamed:strName];
        UIImageView* iView=[[UIImageView alloc]initWithImage:image];
        iView.frame=CGRectMake(3+(i%3)*100, 10+(i/3)*150, 90, 130);
        [sv addSubview:iView];
        
        
        //加手勢
        iView.userInteractionEnabled=YES;
        UITapGestureRecognizer* tap=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(pressTap:)];
        
        //單次單擊
        tap.numberOfTapsRequired=1;
        //單個手指
        tap.numberOfTouchesRequired=1;
        [iView addGestureRecognizer:tap];
    }
    [self.view addSubview:sv];
    
}

其中創(chuàng)建每個圖片視圖并設(shè)置他們的的位置用到了for循環(huán)，這里比較巧妙用取余和除法兩個運算得到圖片的行列數(shù)，然后錯位以顯示圖片。

得到的效果如下：

屏幕快照 2016-12-02 下午8.42.31.png

3. 實現(xiàn)視圖切換

為了創(chuàng)建一個用于顯示大圖片的視圖，我們再新建一個視圖控制器類型的文件VCImageShow。
我們用三種方法來實現(xiàn)這個功能，分別是傳遞圖像標(biāo)簽，傳遞圖片和傳遞圖像視圖。
首先在VCImageShow.h中聲明這三種方法要用到的變量：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #d12f1b}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #bb2ca2}span.s1 {font-variant-ligatures: no-common-ligatures; color: #78492a}span.s2 {font-variant-ligatures: no-common-ligatures}span.s3 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s4 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s5 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s6 {font-variant-ligatures: no-common-ligatures; color: #703daa}

#import <UIKit/UIKit.h>

@interface VCImageShow : UIViewController

//分別用以下三種方法將點擊的視圖傳遞下去
@property(nonatomic,assign)NSUInteger imgTag;
@property(nonatomic,retain)UIImage* image;
@property(nonatomic,retain)UIImageView* imgView;

@end

第一種方法：傳遞圖像視圖
在VCImageShow.m中：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #008400}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}span.s1 {font-variant-ligatures: no-common-ligatures}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s4 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s5 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}span.s6 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s7 {font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s8 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s9 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s10 {font-variant-ligatures: no-common-ligatures; color: #272ad8}

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.view.backgroundColor=[UIColor yellowColor];
    
    //傳imgView：
    self.title=@"圖片展示";
    _imgView.frame=CGRectMake(0, 0, 320, 480);
    [self.view addSubview:_imgView];
}

在VCRoot.m中實現(xiàn)觸發(fā)函數(shù)：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}span.s1 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures}span.s4 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s5 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s6 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s7 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s8 {font-variant-ligatures: no-common-ligatures; color: #703daa}

-(void)pressTap:(UITapGestureRecognizer*) tap
{
    UIImageView* imageView=(UIImageView*)tap.view;
    //創(chuàng)建顯示視圖控制器
    VCImageShow* imageShow=[[VCImageShow alloc]init];
    //將點擊的圖像賦值
    imageShow.imgView=imageView;
    //將顯示視圖控制器推出
    [self.navigationController pushViewController:imageShow animated:YES];
}

特點：代碼最簡單，但是有bug，就是點過的圖片退回來之后就不能在小圖中顯示了，如圖：

屏幕快照 2016-12-02 下午8.51.56.png

原因：一個視圖對象只能有一個根視圖，當(dāng)我們把視圖添加到新的父親視圖上時，就會從原來的父親視圖中刪除。所以當(dāng)我們賦給ImageShow視圖了，這個圖片視圖就不在滾動視圖上了。
所以傳遞視圖的方法是不可行的。

第二種方法：傳遞圖片
在VCRoot.m中實現(xiàn)觸發(fā)函數(shù)，傳遞圖片：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}span.s1 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures}span.s4 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s5 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s6 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s7 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s8 {font-variant-ligatures: no-common-ligatures; color: #703daa}

-(void)pressTap:(UITapGestureRecognizer*) tap
{
    UIImageView* imageView=(UIImageView*)tap.view;
    //創(chuàng)建顯示視圖控制器
    VCImageShow* imageShow=[[VCImageShow alloc]init];
    //將點擊的圖像賦值
    imageShow.image=imageView.image;
    //將顯示視圖控制器推出
    [self.navigationController pushViewController:imageShow animated:YES];
}

之后要去VCImageShow.m中創(chuàng)建image并賦值：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #008400}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #4f8187}span.s1 {font-variant-ligatures: no-common-ligatures}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s4 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s5 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}span.s6 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s7 {font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s8 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s9 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s10 {font-variant-ligatures: no-common-ligatures; color: #272ad8}

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.view.backgroundColor=[UIColor yellowColor];
    
    //傳imgView：
    self.title=@"圖片展示";
    _imgView=[[UIImageView alloc]init];
    _imgView.frame=CGRectMake(0, 0, 320, 480);
    _imgView.image=_image;
    [self.view addSubview:_imgView];
}

即可實現(xiàn)效果：

屏幕快照 2016-12-02 下午9.03.50.png

第三種方法：傳遞圖片tag
在VCRoot的viewDidLoad里加一句tag：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}span.s1 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s2 {font-variant-ligatures: no-common-ligatures}span.s3 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s4 {font-variant-ligatures: no-common-ligatures; color: #272ad8}

//圖像對象的tag值
        iView.tag=101+i;

然后實現(xiàn)觸發(fā)函數(shù)：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px 'Heiti SC Light'; color: #008400}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}span.s1 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures}span.s4 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures; color: #000000}span.s5 {font: 11.0px Menlo; font-variant-ligatures: no-common-ligatures}span.s6 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s7 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s8 {font-variant-ligatures: no-common-ligatures; color: #703daa}

-(void)pressTap:(UITapGestureRecognizer*) tap
{
    UIImageView* imageView=(UIImageView*)tap.view;
    //創(chuàng)建顯示視圖控制器
    VCImageShow* imageShow=[[VCImageShow alloc]init];
    imageShow.imgTag=imageView.tag;
    [self.navigationController pushViewController:imageShow animated:YES];
}

在VCImageShow中利用傳進(jìn)來的tag值選取照片賦給顯示視圖：

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo}p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #3d1d81}p.p3 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #008400}p.p4 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #703daa}p.p5 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; min-height: 13.0px}p.p6 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #4f8187}span.s1 {font-variant-ligatures: no-common-ligatures}span.s2 {font-variant-ligatures: no-common-ligatures; color: #bb2ca2}span.s3 {font-variant-ligatures: no-common-ligatures; color: #000000}span.s4 {font-variant-ligatures: no-common-ligatures; color: #3d1d81}span.s5 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures}span.s6 {font-variant-ligatures: no-common-ligatures; color: #703daa}span.s7 {font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s8 {font: 11.0px 'Heiti SC Light'; font-variant-ligatures: no-common-ligatures; color: #d12f1b}span.s9 {font-variant-ligatures: no-common-ligatures; color: #4f8187}span.s10 {font-variant-ligatures: no-common-ligatures; color: #272ad8}

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    self.view.backgroundColor=[UIColor yellowColor];
    
    //傳imgView：
    self.title=@"圖片展示";
    _imgView=[[UIImageView alloc]init];
    _imgView.frame=CGRectMake(0, 0, 320, 480);
    _imgView.image=_image;
    
    _imgView.image=[UIImage imageNamed:[NSString stringWithFormat:@"%lu.jpg",_imgTag-100]];
    
    [self.view addSubview:_imgView];
}

即可。
