主要用到的方法是UIView animation和3D效果主要的代碼如下
1.創(chuàng)建背景的view給View添加手勢
- (void)viewDidLoad {
[super viewDidLoad];
UIView * view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
view.backgroundColor = [UIColor redColor];
self.myView = view;
[self.myView setUserInteractionEnabled:YES];
UITapGestureRecognizer * tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapped:)];
[view addGestureRecognizer:tap];
[self.view addSubview:view];
}
2.添加3D效果的動畫
-(CATransform3D)firstTransform{
CATransform3D t1 = CATransform3DIdentity;
t1.m34 = 1.0/-900;
t1 = CATransform3DScale(t1, 0.95, 0.95, 1);
//繞x旋轉(zhuǎn)
t1 = CATransform3DRotate(t1, 15.0*M_PI/180.0, 1, 0, 0);
return t1;
}
-(void)tapped:(UITapGestureRecognizer *)tap{
[UIView animateWithDuration:0.3 animations:^{
[self.myView.layer setTransform:[self firstTransform]];
UIView * all = [[UIView alloc]initWithFrame:CGRectMake(0, self.view.bounds.size.height, [UIScreen mainScreen].bounds.size.width, 400)];
self.allView = all;
UITapGestureRecognizer * tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tap:)];
[all addGestureRecognizer:tap];
all.backgroundColor = [UIColor yellowColor];
UIWindow * window = [[UIApplication sharedApplication].windows lastObject];
[window addSubview:all];
}completion:^(BOOL finished) {
[UIView animateWithDuration:0.3 animations:^{
//縮小紅色View的面積并且改變黃色View的Y值
self.myView.transform = CGAffineTransformMakeScale(0.9, 0.95);
self.allView.frame = CGRectMake(0, self.view.bounds.size.height - 400, [UIScreen mainScreen].bounds.size.width, 400);
} completion:^(BOOL finished) {
}];
}];
}
#pragma mark---點擊歸為
- (CATransform3D)firstTransfrom3{
CATransform3D t1 = CATransform3DIdentity;
t1.m34 = 1.0/-00;
t1 = CATransform3DScale(t1, 1, 1, 1);
t1 = CATransform3DRotate(t1, 15*M_PI/180.0, 1, 0, 0);
return t1;
}
- (void)tap:(UITapGestureRecognizer *)tap{
[UIView animateWithDuration:0.3 animations:^{
self.allView.frame = CGRectMake(0, self.view.frame.size.height, [UIScreen mainScreen].bounds.size.width, 400);
[self.myView.layer setTransform:[self firstTransfrom3]];
} completion:^(BOOL finished) {
[self.allView removeFromSuperview];
[UIView animateWithDuration:0.3 animations:^{
self.myView.transform = CGAffineTransformMakeScale(1, 1);
}];
}];
}
