iphone - 如何在 iphone 应用程序中实现图像翻转动画

Question

如何实现图像向右翻转动画。下面给出的代码。请帮忙。

imageview.animationImages=[NSArray arrayWithObjects:  
   [UIImage imageNamed:@"image1.png"],
   [UIImage imageNamed:@"imag2.png"],
   [UIImage imageNamed:@"imag3.png"],
   [UIImage imageNamed:@"imag4.png"],
   [UIImage imageNamed:@"imag5.png"], 
   [UIImage imageNamed:@"imag6.png"],
   [UIImage imageNamed:@"imag7.png"], nil];

imageview.animationDuration=15.0;
imageview.animationRepeatCount=0;
[imageview startAnimating];

Answer 1

用于垂直翻转

[UIView animateWithDuration:1.0 animations:^{
    yourView.layer.transform = CATransform3DMakeRotation(M_PI,1.0,0.0,0.0);
} completion:^(BOOL finished){
    // code to be executed when flip is completed
}];

用于水平翻转

[UIView animateWithDuration:1.0 animations:^{
    yourView.layer.transform = CATransform3DMakeRotation(M_PI,0.0,1.0,0.0);
} completion:^(BOOL finished){
    // code to be executed when flip is completed
}];

并且不要忘记将 QuartzCore 框架添加到项目中并导入

#import <QuartzCore/QuartzCore.h>

Answer 2

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];

[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:imageview cache:NO];
[UIView commitAnimations];

我认为这段代码可以帮助你。
