圖像不動畫

Question

我想要自動一個一個地滑動圖像我正在從圖像路徑從服務器獲取圖像，但它始終只顯示一個圖像我應該怎麼做？

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]; 
    }

因爲您的數組全部只包含1個圖像。你的代碼應該如下所示。

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];
