架构设置为 64 位时图像不显示

Images not showing up when architecture set to 64 bit(架构设置为 64 位时图像不显示)

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)";

ARCHS = "$(ARCHS_STANDARD_INCLUDING_64_BIT)";

应用程序运行良好，只是某些图像未显示(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?

推荐答案

答案就在这里:

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(在实现 viewController 上面的 .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

即使没有显示图像的按钮不在滚动视图中，在上面添加评论也解决了问题.

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