本文介绍了当架构设置为 64 位时，图像不显示的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

为了将我的应用程序转换为 64 位，我将架构构建设置更改为:

For transitioning my app to 64-bit, I changed the Architectures build setting to:

ARCHS = "$(ARCHS_STANDARD_INCLUDING_64_BIT)";

应用程序运行良好，只是有些图像没有显示(空白).为什么会发生?有什么线索吗?

App is runnig fine except that some of the images are not showing up (blank). Why would it happen? any clues?

我找到了原因.在尚未分配但包含在应用程序中的 viewController 中，实现了以下内容(在上面实现 viewController 的 .m 文件中):

I found the reason. In a viewController, which was not yet allocated, but included in the app, there was following implemented (in the .m-file above implementation viewController):

@implementation UIImageView (UIScrollView)
- (void)setAlpha:(float)alpha {
..........(no difference if here is some code or not) ...............
  [super setAlpha:alpha];
}
@end

即使不显示图像的按钮不在滚动视图中，但将上面的注释放在上面解决了问题.

Putting above in comment solved the problem, even though the button which didn't display the image wasn't in a scrollview.
