Question

我想知道是否可以同时编写不同的UIView动画。我试图同时使用精灵动画为两个Apple风格的翻转计数器制作动画。每个翻转计数器都有自己的动画。问题是第二个翻转计数器在第一个计数器完成时开始运行。

EDITED两次：这是代码：https://dl.dropbox.com/u/1348024/MultipleFlipCounters.zip

有两个简单的类“FlipCounterView.m”和“CounterViewController”。点击屏幕“CounterViewController”将启动动画。谢谢！

编辑：

添加了相关代码。

Apple风格的翻转计数器精灵动画是完成FlipCounterView类。

- (void)viewDidLoad{
[super viewDidLoad];
flipCounter1 = [[FlipCounterView alloc] initWithFrame:CGRectMake(0, 0, 200, 200)];
[flipCounter1 add:10];
[self.view addSubview:flipCounter1];

flipCounter2 = [[FlipCounterView alloc] initWithFrame:CGRectMake(0, 120, 200, 200)];
[flipCounter2 add:10];
[self.view addSubview:flipCounter2];
}

点击屏幕：

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

[UIView animateWithDuration:0.5
                     animations:^{
                         //this method made an sprite animation on flipCounter1
                         [flipCounter1 distributedAdd:150 overSeconds:0 withNumberOfIterations:3];
                     }];

[UIView animateWithDuration:0.5
                     animations:^{
                         //this method made an sprite animation on flipCounter2
                         [flipCounter2 distributedAdd:150 overSeconds:0 withNumberOfIterations:3];
                     }];

}

您的代码崩溃，但在修复崩溃后尝试一下：

- (void)animateNow1
{
    [UIView animateWithDuration:0.5
                     animations:^{
                         [flipCounter1 distributedAdd:150 overSeconds:0 withNumberOfIterations:3];
                     }];

}
- (void)animateNow2
{
    [UIView animateWithDuration:0.5
                     animations:^{
                         [flipCounter2 distributedAdd:150 overSeconds:0 withNumberOfIterations:3];
                     }];
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [self performSelector:@selector(animateNow1) withObject:nil afterDelay:0.00];
    [self performSelector:@selector(animateNow2) withObject:nil afterDelay:0.00];
}

Answer 2

代码中的崩溃似乎与动画（Xcode 4.5.1）无关，如果你想同时执行两个动画，你可以在一个动画块中执行此操作（因为动画属性是相同的）。 / p>

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [UIView animateWithDuration:0.5 animations:^{
        [flipCounter1 distributedAdd:150 overSeconds:0 withNumberOfIterations:3];
        [flipCounter2 distributedAdd:150 overSeconds:0 withNumberOfIterations:3];
    }];
}

UIView主线程。 2 UIView同时动画
