图像不动画

Question

我想要自动一个一个地滑动图像我正在从图像路径从服务器获取图像，但它始终只显示一个图像我应该怎么做？

for (SliderDC *slider in imagesArray) { 
     sliderImageName = slider.sliderImagePath; 
      NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString: [NSString stringWithFormat:@"%@%@",kWSURL, sliderImageName]]]; 
      UIImage *imgOne = [UIImage imageWithData:imageData]; 
    ////  likely download all images from web service and create an array like 
    // 
      NSArray *imagesArrays = [NSArray arrayWithObjects:imgOne, nil]; 

////  and use with little modification 
    // 
     UIImageView* animatedImageView = [[UIImageView alloc] initWithFrame:self.view.bounds]; 
     animatedImageView.animationImages = imagesArrays; 
     animatedImageView.animationDuration = 0.5f; 
     animatedImageView.animationRepeatCount = 0; 

     [self.view addSubview: animatedImageView]; 
     [animatedImageView startAnimating]; 
    }

因为您的数组全部只包含1个图像。你的代码应该如下所示。

NSMutableArray *imagesArrays= [[NSMutableArray alloc]init]; 
for (SliderDC *slider in imagesArray) { 
    sliderImageName = slider.sliderImagePath; 
     NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString: [NSString stringWithFormat:@"%@%@",kWSURL, sliderImageName]]]; 
     if(imageData) 
      UIImage *imgOne = [UIImage imageWithData:imageData]; 
      if(imgOne) 
       [imagesArrays addObject:imgOne]; 
} 

// after adding all image in array then add animation. 
UIImageView* animatedImageView = [[UIImageView alloc] initWithFrame:self.view.bounds]; 
animatedImageView.animationImages = imagesArrays; 
animatedImageView.animationDuration = 0.5f; 
animatedImageView.animationRepeatCount = 0; 

[self.view addSubview: animatedImageView]; 
[animatedImageView startAnimating];
