近來無事就把項(xiàng)目中有關(guān)封裝玩意兒整理一下。話不多說直接上菜。
UIButton 簡單封裝
UIButton 屬性很多所以很多都不敢寫進(jìn)去怕啰嗦 剩下的大家可以根據(jù)自己的需求進(jìn)行添加(以下控件不在多說)。
+(UIButton*)CreateUIButtonWithButtonTitle:(NSString*)title buttonFrame:(CGRect)rect UIFont:(CGFloat)titleSize titleColor:(UIColor*)titleColor buttonAction:(SEL)buttonAction superView:(UIView*)superView
其他屬性可自行添加
+(UIButton*)CreateUIButtonWithButtonTitle:(NSString*)title buttonFrame:(CGRect)rect UIFont:(CGFloat)titleSize titleColor:(UIColor*)titleColor buttonAction:(SEL)buttonAction superView:(UIView*)superView{
UIButton *button =[UIButton buttonWithType:UIButtonTypeCustom];
[button setFrame:rect];
[button setTitle:title forState:UIControlStateNormal];
[button setTitleColor:titleColor forState:UIControlStateNormal];
[button addTarget:nil action:buttonAction forControlEvents:UIControlEventTouchUpInside];
[[button titleLabel] setFont:[UIFont systemFontOfSize:titleSize]];
[superView addSubview:button];
return button;
}
UILabel 控件封裝
+(UILabel*)CreateUILabelWithLabelTitle:(NSString*)title labelFrame:(CGRect)rect BackgroundColor:(UIColor*)bageColor UIFont:(CGFloat)titleSize numberOfLine:(NSInteger)numberLine textAlignment:(NSTextAlignment)textAlignment superView:(UIView*)superView;
其他屬性可自行添加
+(UILabel*)CreateUILabelWithLabelTitle:(NSString *)title labelFrame:(CGRect)rect BackgroundColor:(UIColor *)bageColor UIFont:(CGFloat)titleSize numberOfLine:(NSInteger)numberLine textAlignment:(NSTextAlignment)textAlignment superView:(UIView*)superView{
UILabel *label =[[UILabel alloc] initWithFrame:rect];
[label setText:title];
[label setBackgroundColor:bageColor];
[label setFont:[UIFont systemFontOfSize:titleSize]];
[label setTextAlignment:textAlignment];
[label setNumberOfLines:numberLine];
[superView addSubview:label];
return label;
}
UIAlertController 原生彈框封裝
UIAlertControllerStyleAlert
+(void)showAlertControllerWithTitle:(NSString *)title Message:(NSString *)message AactionCancleTitle:(NSString *)cancleTitle ActionSureTitle:(NSString *)sureTitle cancleAction:(void (^)(UIAlertAction * action))cancleAction sureAction:(void (^)(UIAlertAction *action))sureAction Controller:(UIViewController *)controller;
多余信息可直接用nil填充
+(void)showAlertControllerWithTitle:(NSString *)title Message:(NSString *)message AactionCancleTitle:(NSString *)cancleTitle ActionSureTitle:(NSString *)sureTitle cancleAction:(void (^)(UIAlertAction * action))cancleAction sureAction:(void (^)(UIAlertAction * action))sureAction Controller:(UIViewController *)controller{
UIAlertController *alert =[UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *CancleAction =[UIAlertAction actionWithTitle:cancleTitle style:UIAlertActionStyleCancel handler:cancleAction];
UIAlertAction *SureAction =[UIAlertAction actionWithTitle:sureTitle style:UIAlertActionStyleDefault handler:sureAction];
if (cancleTitle !=nil) {
[alert addAction:CancleAction];
}
if (sureTitle !=nil) {
[alert addAction:SureAction];
}
[controller presentViewController:alert animated:YES completion:nil];
}
UIAlertControllerStyleActionSheet
+(void)showActionSheetAlertControllerWithTitle:(NSString*)title Message:(NSString*)message AactionCancleTitle:(NSString*)cancleTitle cancleAction:(void (^)(UIAlertAction * action))cancleAction contentArrays:(NSArray*)contentArrays alertAction:(void (^)(UIAlertAction *action))action Controller:(UIViewController *)controller;
+(void)showActionSheetAlertControllerWithTitle:(NSString *)title Message:(NSString *)message AactionCancleTitle:(NSString *)cancleTitle cancleAction:(void (^)(UIAlertAction *))cancleAction contentArrays:(NSArray *)contentArrays alertAction:(void (^)(UIAlertAction *))action Controller:(UIViewController *)controller{
UIAlertController *alertController =[UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleActionSheet];
if (cancleTitle !=nil) {
UIAlertAction *canclAction = [UIAlertAction actionWithTitle:cancleTitle style:UIAlertActionStyleCancel handler:cancleAction];
[alertController addAction:canclAction];
}
if (contentArrays.count > 0) {
for (int i = 0; i<contentArrays.count; i++) {
UIAlertAction *Actions = [UIAlertAction actionWithTitle:contentArrays[i] style:UIAlertActionStyleDefault handler:action];
[alertController addAction:Actions];
}
}
[controller presentViewController:alertController animated:YES completion:nil];
}
AFNetworking 數(shù)據(jù)上傳下載封裝
上傳文件
+(void)UploadFileWithURL:(NSString *)url image:(UIImage*)image parameters:(NSDictionary *)param Progress:(void (^)(NSProgress * uploadProgress))progress complete:(void (^)(NSURLSessionDataTask * task, id responseObject))success failure:(void (^)(NSURLSessionDataTask * task, NSError * error))failure;
上傳前應(yīng)跟后臺(tái)溝通一下。

4. 上傳文件的[mimeType]
*/
[formData appendPartWithFileData:data name:@"file" fileName:fileName mimeType:@"image/png"];
} progress:^(NSProgress * _Nonnull uploadProgress) {
/*
int64_t totalUnitCount 需要下載文件的總大小
int64_t completedUnitCount 當(dāng)前已經(jīng)下載的大小
*/
NSLog(@"%f",1.0 * uploadProgress.completedUnitCount / uploadProgress.totalUnitCount);
dispatch_async(dispatch_get_main_queue(), ^{

});

NSLog(@"上傳成功 %@", responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
NSLog(@"上傳失敗 %@", error);
}];
}
GET格式請(qǐng)求
+(void)GETrequestWithUrl:(NSString *)urlString parameters:(NSDictionary *)param Complete:(void (^)(NSData * data))success fail:(void (^)(NSError * error))failture;
+(void)GETrequestWithUrl:(NSString *)urlString parameters:(NSDictionary *)param Complete:(void (^)(NSData *))success fail:(void (^)(NSError *))failture

manager.responseSerializer = [AFHTTPResponseSerializer serializer];
urlString =[urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
[manager GET:urlString parameters:param progress:^(NSProgress * _Nonnull downloadProgress) {
} success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) {
//調(diào)用success的block
success(responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
failture(error);
}];
}
POST格式請(qǐng)求
+(void)POSTrequestWithUrl:(NSString *)urlString parameters:(NSDictionary *)param Complete:(void (^)(NSData * data))success fail:(void (^)(NSError * error))failture;
+(void)POSTrequestWithUrl:(NSString *)urlString parameters:(NSDictionary *)param Complete:(void (^)(NSData *))success fail:(void (^)(NSError *))failture

}
時(shí)間戳轉(zhuǎn)換不同格式的時(shí)間
+ (NSString*)fromTimeInterval:(NSString*)timerInterval fromType:(NSInteger)type;
根據(jù)項(xiàng)目需求自行修改
+ (NSString*)fromTimeInterval:(NSString*)timerInterval fromType:(NSInteger)type{
NSTimeInterval time =[timerInterval doubleValue]/ 1000;
NSDate *detaildate=[NSDate dateWithTimeIntervalSince1970:time];
//實(shí)例化一個(gè)NSDateFormatter對(duì)象
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
//設(shè)定時(shí)間格式,這里可以設(shè)置成自己需要的格式

自定義標(biāo)簽
標(biāo)簽定制在項(xiàng)目中的需求越來越常見我自己特意封裝了一個(gè)View 代碼簡潔、引用方便、不確定標(biāo)簽個(gè)數(shù)的時(shí)候可以計(jì)算View 高度、支持單選和多選。

簡單引用

};
[self.view addSubview:labelView];
計(jì)算高度
NSArray *titles = @[@"語文書",@"小馬是個(gè)大逗逼",@"端午節(jié)快樂",@"我與僵尸有個(gè)約會(huì)DVD版",@"說好的。。。呢",@"干什么啊",@"智商堪憂",@"逗逼",@"我們要去旅游去了你去嗎",@"我不去你去吧",@"哎真是的",@"你說啊為什么啊",@"不去拉倒",@"真是的"];
/**
* 計(jì)算 不固定Titles 高度 如果titles 固定可直接填寫高度。
*/
