Cannot access UIImage class without importing UIKit.h in Xcode 6?
提问by luna_
#import <Foundation/Foundation.h>
@interface FaceObject : NSObject
@property (strong, nonatomic) UIImage *image;
@end
Xcode gives an error saying "unknown type name 'UIImage' unless I import UIKit.h, but in Xcode 5 i would have not gotten this error and did not need to import UIKit -- is there any explanation for this? Am I doing something wrong? Thanks!
Xcode 给出一个错误，说“未知类型名称‘UIImage’，除非我导入 UIKit.h，但在 Xcode 5 中我不会得到这个错误并且不需要导入 UIKit——对此有任何解释吗？我在做什么吗？错了？谢谢！

Xcode 6 no longer includes a .pch file by default. In previous versions, that file included the UIKit import (more info here - Why isn't ProjectName-Prefix.pch created automatically in Xcode 6?).
默认情况下，Xcode 6 不再包含 .pch 文件。在以前的版本中，该文件包含 UIKit 导入（更多信息在这里 -为什么 ProjectName-Prefix.pch 不在 Xcode 6 中自动创建？）。

In 2015 -- still getting this error. I always forget to include
在 2015 年 - 仍然收到此错误。我总是忘记包括
#import <UIKit/UIKit.h>
That should take care of it.
那应该照顾它。
