ios - 逐帧动画 UIImageView

Question

我有一个关于如何使用逐帧方法添加动画 UIImageView 的想法，但我的问题是关于如何为 UIImageView 添加动画 ALREADY 作为 IBOutlet UIImageView 添加到 View Controller Storyboard上。

代码的和平会改变什么？!

NSArray *myImages = [NSArray arrayWithObjects:
                         [UIImage imageNamed:@"bookmark1.png"],
                         [UIImage imageNamed:@"bookmark2.png"],
                         [UIImage imageNamed:@"bookmark3.png"],
                         [UIImage imageNamed:@"bookmark4.png"],
                         [UIImage imageNamed:@"bookmark5.png"],nil];

    myAnimatedView = [UIImageView alloc];

   [myAnimatedView initWithFrame:CGRectMake(0, 0, 131, 125)];

    myAnimatedView.animationImages = myImages;

    myAnimatedView.animationDuration = 0.25;

    myAnimatedView.animationRepeatCount = 1;

    [myAnimatedView startAnimating];

    [self.navigationController.view addSubview:myAnimatedView];

我想通过我的 viewController 为这张图片设置动画

Answer 1

它甚至更容易。首先，在 .h 文件中添加:

@property (nonatomic, retain) IBOutlet UIImageView *iV;

之后，将此 socket 连接到 Storyboard上的实际 UIImageView。更改您的代码:

iV.animationImages = myImages;
iV.animationDuration = 0.25;
iV.animationRepeatCount = 1;
[iV startAnimating];

仅此而已。希望这有帮助

附注是的，不要忘记 iV = nil；在 - (void)viewDidUnload 方法中

UPD:已添加

[self performSelector:@selector(animationDone) withObject:nil afterDelay:0.25];

startAnimating 调用后，显然添加了 animationDone 方法:

- (void)animationDone {
    [iV stopAnimating];
    [iV setImage:[UIImage imageNamed:@"bookmark5.png"]];
}
