Question

这是我的代码：

-(void) createNewImage {

image.animationImages = [NSArray arrayWithObjects:
                         [UIImage imageNamed:@"oeufgrisé.png"],
                         [UIImage imageNamed:@"abouffer_03.png"],
                         [UIImage imageNamed:@"boutonplay_03.png"],
                         [UIImage imageNamed:@"boutonpause_03.png"],
                         [UIImage imageNamed:@"abouffer_05.png"],
                         [UIImage imageNamed:@"mangeurcentremieu3_03.png"],nil];
[image setAnimationRepeatCount:10];
image.animationDuration =1.5;
[image startAnimating];      

imageView = [[UIImageView alloc] initWithImage:image];

}

这段代码不起作用，我不知道为什么。我总是在这行警告“imageView = [[UIImageView alloc] initWithImage：image];” ：不兼容的ObjectiveC类型struct UIImageView *'期望的结构UIImage *'从不同的Objective C类型传递initWithImage的参数1时

您可以将动画图像设置为UIImageView，而不是UIImage。

-(void) createNewImage {
    imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,460)];

    imageView.animationImages = [NSArray arrayWithObjects:
                             [UIImage imageNamed:@"oeufgrisé.png"],
                             [UIImage imageNamed:@"abouffer_03.png"],
                             [UIImage imageNamed:@"boutonplay_03.png"],
                             [UIImage imageNamed:@"boutonpause_03.png"],
                             [UIImage imageNamed:@"abouffer_05.png"],
                             [UIImage imageNamed:@"mangeurcentremieu3_03.png"],nil];
    [imageView setAnimationRepeatCount:10];
    imageView.animationDuration =1.5;
    [imageView startAnimating]; 
    [NSTimer scheduledTimerWithTimeInterval:15.0 target:self selector:@selector(setLastImage:) userInfo:nil repeats:NO];

 }

-(void)setLastImage:(id)obj
{
    [imageView performSelectorOnMainThread:@selector(setImage:) withObject:[UIImage imageNamed:@"mangeurcentremieu3_03.png"] waitUntilDone:YES];
}

如果你这样做：

image.animationImages = [NSArray arrayWithObjects:

然后image是UIImageView（查看您分配代码的代码）。这就是你得到错误的原因，因为initWithImage期望一个UIImage类型的对象：

- (id)initWithImage:(UIImage *)image

你不是说image是图像视图，或者你可能不需要在方法中分配第二个UIImageView，而只能使用image。

确保image是UIImageView而不是UIImage。您只能为UIImageViews创建animationImages。
