常用动画

第一、实现左右移动

[objc]  view plain copy print ?

1. <span style="font-size:18px;">    [UIView beginAnimations:@"testAnimation" context:@"test"];  
2.     [UIView setAnimationDuration:0.5];  
3.    [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];  
4.     [UIView setAnimationDelegate:self];  
5.     [UIView setAnimationDidStopSelector:@selector(animationStop)];  
6.     CGRect frame=self.myView.frame;  
7.     frame.origin.x=10;  
8.     self.myView.frame=frame;  
9.     [UIView commitAnimations];  
10. </span>  

第二、利用block来实现动画，回调简单方便

[objc]  view plain copy print ?

1. <span style="font-size:18px;">    [UIView animateWithDuration:0.5 animations:^{  
2.         CGRect frame=self.myView.frame;  
3.            frame.origin.y=300;  
4.             self.myView.frame=frame;  
5.         //self.myView.alpha=0.0;  
6.   
7.     } completion:^(BOOL finished)  
8.      {  
9.          [UIView animateWithDuration:0.5 animations:^{  
10.              //self.myView.alpha=1.0;  
11.              CGRect frame=self.myView.frame;  
12.              frame.origin.y=10;  
13.              self.myView.frame=frame;  
14.          }];  
15.   
16.      }];  
17. </span>  

在completion后面的实现前面动画结束后的调用的方法

第三、实现渐入渐出得效果

[objc]  view plain copy print ?

1. <span style="font-size:18px;">    [UIView animateWithDuration:0.5 animations:^{  
2.   
3.         self.myView.alpha = 0;  
4.   
5.     } completion:^(BOOL finished)  
6.      {  
7.          self.myView.alpha = 1;  
8.      }];  
9. </span>  

第四、实现放大缩小

[objc]  view plain copy print ?

1. <span style="font-size:18px;">    self.myView.transform=CGAffineTransformScale(self.myView.transform, 1, 1);  
2.     [UIView animateWithDuration:0.5 animations:^{  
3.   
4.         self.myView.transform=CGAffineTransformScale(self.myView.transform, 0.1, 0.1);  
5.     } completion:^(BOOL finished)  
6.      {  
7.          [UIView animateWithDuration:0.5 animations:^{  
8.              self.myView.transform=CGAffineTransformIdentity;  
9.          }];  
10.   
11.      }];  
12. </span>  

第五、两个动画间的过渡动画

上面讲的动画是针对一个动画的旋转、平移、放大缩小，我们分析两个动画在切换时的动画效果

[objc]  view plain copy print ?

1. <span style="font-size:18px;">    [UIView beginAnimations:nil context:nil];  
2.     [UIView setAnimationDuration:0.5];  
3.     [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.parentView cache:YES];  
4.     [UIView commitAnimations];  
5.       
6.     [self.parentView exchangeSubviewAtIndex:0 withSubviewAtIndex:1];</span>  

Block方法的实现：

[objc]  view plain copy print ?

1. <span style="font-size:18px;">    [UIView transitionWithView:self.parentView duration:1 options:UIViewAnimationOptionTransitionFlipFromLeft animations:^{  
2.         [self.parentView exchangeSubviewAtIndex:1 withSubviewAtIndex:0];  
3.     } completion:NULL];  
4. </span>  

第六、修改pushviewcontroller切换动画效果

[objc]  view plain copy print ?

1. <span style="font-size:18px;">    [UIView beginAnimations:nil context:nil];  
2.     [UIView setAnimationDuration:0.5];  
3.     [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:YES];  
4.     [UIView commitAnimations];  
5.     UIViewController *viewContr = [[UIViewController alloc] init];  
6.    [self.navigationController pushViewController:viewContr animated:NO];</span>
