问题描述

UIImageView不加载图片

使用ImageView从url加载图片失败：

   pdfView.hidden=NO;
   webView.hidden=NO;
   pictureImageView.hidden=NO;
  pdfView.backgroundColor=[UIColor clearColor];
  doneButton = [[UIBarButtonItem alloc]initWithTitle:@" Done " style:UIBarButtonItemStyleBordered target:self action:@selector(doneButtonClick)];
  self.navigationItem.leftBarButtonItem =doneButton;
  webView.backgroundColor=[UIColor clearColor];

    NSLog(@"File Name is %@",fileName);

    NSLog(@"Enterning in the ImageSection");

    NSString *ImageURL = fileName;
    NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:ImageURL]];
        pictureImageView.image = [UIImage imageWithData:imageData];

同时，如果我要从本地读取也不显示：

  pictureImageView.image=[UIImage imageNamed:@"starblue.png"];

请高手帮忙，谢谢

解决方案

先设置图片的框架，然后添加图片到pictureImageView中写下这行代码：

        [self.view bringSubviewToFront:pictureImageView];

解决方案二：

用这段代码显示图片：

  NSString *image=[NSString stringWithFormat:@"Your URL"] stringByReplacingOccurrencesOfString:@" " withString:@"%20"];

            NSLog(@"%@",image);
            NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:image]];

            Yourimageview=[UIImage imageWithData:imageData];
