ios - Iphone 上的幻灯片和过渡？

Question

我有以下代码的问题。

如果我使用这些代码并在模拟器上运行它，他只会向我显示数组中带有过渡的前两张图片。如果我在 Iphone 上运行它，他只显示第一张照片。 他也不重复这些照片。-

我做错了什么？

    - (void)viewDidLoad{
    [super viewDidLoad];

    welcomePhoto = [NSArray arrayWithObjects:@"Bild.jpeg",@"Bild1.jpeg", @"Bild2.png", nil];
    imageView.image = [UIImage imageNamed:[welcomePhoto objectAtIndex:0]];
    [NSTimer scheduledTimerWithTimeInterval:3.0 target:self selector:@selector(transitionPhotos) userInfo:nil repeats:YES];
}


-(void)transitionPhotos{
    int photoCount;
    if (photoCount < [welcomePhoto count] - 1){
        photoCount ++;
    }else{
        photoCount = 0;
    }
    [UIView transitionWithView:self.imageView
                      duration:2.0
                       options:UIViewAnimationOptionTransitionCrossDissolve
                    animations:^{ imageView.image = [UIImage imageNamed:[welcomePhoto objectAtIndex:photoCount]]; }
                    completion:NULL];    
}

尝试在 viewDidLoad 中添加它。

UIImageView* animatedImageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 90, 100, 100)];
[self.view addSubview:animatedImageView];
animatedImageView.animationImages = [NSArray arrayWithObjects:    
                                     [UIImage imageNamed:@"bild.png"],
                                     [UIImage imageNamed:@"bild.png"],
                                     [UIImage imageNamed:@"bild.png"], nil]; //etc
animatedImageView.animationDuration = 3.0f * [animatedImageView.animationImages count];
animatedImageView.animationRepeatCount = 0;
[animatedImageView startAnimating];
[self.view addSubview: animatedImageView];
