iphone - 动画和调整 UIImageView

Question

如何设置 UIImageView 的动画和调整其大小？我试过这样做，但对我来说没有用:

[UIView beginAnimations:nil context:NULL];
            [UIView setAnimationDuration:1.0];
            imgView.frame = CGRectMake(0, 0, 320, 480);
            [UIView commitAnimations];

Answer 1

尝试使用 block 动画:

[UIView animateWithDuration:1.0f // This can be changed.
                 animations:^{
                   CGRect frame = imageView.frame;
                   frame.size.width += 100.0f; // This is just for the width, but you can change the origin and the height as well.
                   imageView.frame = frame;
                 } 
                 completion:^(BOOL finished){
                 }];

希望对您有所帮助!
