Question

我这里有一个奇怪的问题。我为简单的页面翻转设置了两个动画。然后我有一个随机生成1或0的按钮。如果数字为0则执行一个动画，如果它为1则执行另一个动画。

我所看到的问题是，这一切都在模拟器上运行良好，但在设备上，如果随机数为0，它就不会执行动画。

任何线索？

    -(IBAction)pageTurn:(id)sender {
    int randomNumber = arc4random() %2;
    NSLog(@"randomNumber = %d", randomNumber);
    if (randomNumber == 0) {
        [self turnPageForward];
    } else {
        [self turnPageBackward];
    }
}

-(void)turnPageForward {
    NSArray *myImages = [NSArray arrayWithObjects:
                         [UIImage imageNamed:@"PageTurnOne.png"],
                         [UIImage imageNamed:@"PageTurnTwo.png"],
                         [UIImage imageNamed:@"PageTurnThree.png"],
                         [UIImage imageNamed:@"PageTurnFour.png"],
                         [UIImage imageNamed:@"PageTurnFive.png"],
                         [UIImage imageNamed:@"PageTurnSix.png"],
                         [UIImage imageNamed:@"PageTurnSeven.png"],
                         [UIImage imageNamed:@"PageTurnEight.png"],
                         [UIImage imageNamed:@"PageTurnNine.png"],
                         nil];

    UIImageView *myAnimatedView = [UIImageView alloc];
    [myAnimatedView initWithFrame:CGRectMake(0, 0, 320, 480)];
    myAnimatedView.animationImages = myImages;
    myAnimatedView.animationDuration = .5; // seconds
    myAnimatedView.animationRepeatCount = 1; // 0 = loops forever
    [myAnimatedView startAnimating];
    [self.view addSubview:myAnimatedView];
    [myAnimatedView release]; 
}

-(void)turnPageBackward {
    NSArray *myImages = [NSArray arrayWithObjects:
                         [UIImage imageNamed:@"PageTurnNine.png"],
                         [UIImage imageNamed:@"PageTurnEight.png"],
                         [UIImage imageNamed:@"PageTurnSeven.png"],
                         [UIImage imageNamed:@"PageTurnSix.png"],
                         [UIImage imageNamed:@"PageTurnFive.png"],
                         [UIImage imageNamed:@"PageTurnFour.png"],
                         [UIImage imageNamed:@"PageTurnThree.png"],
                         [UIImage imageNamed:@"PageTurnTwo.png"],
                         [UIImage imageNamed:@"PageTurnOne.png"],
                         nil];

    UIImageView *myAnimatedView = [UIImageView alloc];
    [myAnimatedView initWithFrame:CGRectMake(0, 0, 320, 480)];
    myAnimatedView.animationImages = myImages;
    myAnimatedView.animationDuration = .5; // seconds
    myAnimatedView.animationRepeatCount = 1; // 0 = loops forever
    [myAnimatedView startAnimating];
    [self.view addSubview:myAnimatedView];
    [myAnimatedView release]; 
}

通常，当设备上的代码失败但模拟器失败时（反之亦然），罪魁祸首是为一个硬件而不是另一个硬件编译的库或其他编译源。

另一个相关的可能性是未正确添加资源，因此它不包含在设备的最终版本中。我会检查方法中的图像文件不起作用。

您还应该确认是否正在调用turnPageForward。这将为您提供问题所在的线索。
