UIImageView没有动画

Question

我的应用程序中有以下代码，但它没有为UIImageView设置动画，有人可以告诉我原因吗？

    UITableViewCell* cell = [selectedTable cellForRowAtIndexPath:selectedPath];

    NSArray* myImageArray = [NSArray arrayWithObjects:
                             [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked117x11" ofType:@"png"]],
                             [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked217x11" ofType:@"png"]],
                             [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked317x11" ofType:@"png"]],
                             [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked417x11" ofType:@"png"]],
                             [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked517x11" ofType:@"png"]],
                             [UIImage imageNamed:[[NSBundle mainBundle] pathForResource:@"boxBeingChecked617x11" ofType:@"png"]],
                             nil];


    cell.imageView.animationImages = myImageArray;
    cell.imageView.animationDuration = 4.20;
    cell.imageView.animationRepeatCount = 1;
    [cell.imageView startAnimating];
    [NSTimer scheduledTimerWithTimeInterval:4.0
                                     target:self
                                   selector:@selector(methodToInvokeAfterAnimationIsDone)
                                   userInfo:nil
                                    repeats:NO];

你应该用这个：

NSArray* myImageArray = [NSArray arrayWithObjects:
                             [UIImage imageNamed:@"boxBeingChecked117x11.png"]],
                             [UIImage imageNamed:@"boxBeingChecked217x11.png"]],
                             [UIImage imageNamed:@"boxBeingChecked317x11.png"]],
                             [UIImage imageNamed:@"boxBeingChecked417x11.png"]],
                             [UIImage imageNamed:@"boxBeingChecked517x11.png"]],
                             [UIImage imageNamed:@"boxBeingChecked617x11.png"]],
                             nil];

您需要在imageNamed：method。

中提供文件的名称，而不是路径

确保imageView的{​​{1}}属性设置为highlighted，否则您上面的代码将无效。如果要为突出显示的图像设置动画，请使用NO。
