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

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.
