Ios 如何在UIImageView/UIWebView中强制转换UIView

我有一个包含

UIWebViews

和

UIImageViews

的滚动视图。 我需要更新此视图，但无法访问其属性

for (UIView *subview in _scrollView.subviews) {
      if([subView isKindOfClass:[UIImageView class]]){
          subview.image = myimage;
      }
      if([subView isKindOfClass:[UIWebView class]]){
          [subview loadData:mydata MIMEType:@"application/pdf" textEncodingName:@"utf-8" baseURL:nil];
      }
}

我的迭代器是UIView，因此无法访问.image UIImageView属性

谢谢

请使用演员阵容：

((UIImageView*)subview).image = myimage;

（或：）

只需创建一个

IBOutlet

，您就可以轻松地从中访问您的ImageView，而iWebView和iImageView都是通过编程方式创建的。我想从UIView访问UIImageView和UIWebView属性。查看上面的代码。

UIImageView *imageView = (UIImageView*)subview;
imageView.image = myimage;

for (UIView *subview in _scrollView.subviews) {
      if([subView isKindOfClass:[UIImageView class]]){
          UIImageView *img = (UIImageView*)subView;
          img.image = myimage;
      }
      if([subView isKindOfClass:[UIWebView class]]){
          UIWebView *webView = (UUIWebView*)subView;
          [webView loadData:mydata MIMEType:@"application/pdf" textEncodingName:@"utf-8" baseURL:nil];
      }
}

for (id subview in _scrollView.subviews) {
  if([subView isKindOfClass:[UIImageView class]]){
      subview.image = myimage;
  }
  if([subView isKindOfClass:[UIWebView class]]){
      [subview loadData:mydata MIMEType:@"application/pdf" textEncodingName:@"utf-8"      baseURL:nil];
  }
}
