好吧，一直试图弄清楚这一点有一段时间我已经设法把它归结为这3个错误，我一直在寻找修复，但没有任何工作，任何人都可以帮助我有了这个？Xcode Objective-C错误需要一些帮助:)

我试图编译的东西，这是它的一部分，这是我需要固定的所有工作，但我不知道该怎么办。

此外，这不是我的代码，如果你想看到原来按照链接归功于Hamzasood

Hamzasood custom watch face

我把错误的代码，以便寻找<旁边 - - //错误只有3

这里如下 1.OnozOmgEditingGuideView.h

@class 
@interface OnozOmgEditingGuideView : UIView { <---//expected identifier 
    UIView *_topView; 
    UILabel *_topLabel; 
    UIView *_bottomView; 
    UILabel *_bottomLabel; 
} 
@end 
/*! 
Set the color shown by the top view. 
    The new color to be displayed 
*/ 
- (void)setTopColor:(UIColor *)color; 
/*! 
Set the color shown by the bottom view. 
@param color 
    The new color to be displayed 
*/ 
- (void)setBottomColor:(UIColor *)color; <---//missing content for method declaration 

其缺少的内容和正在寻找的东西，但我不知道我真的很新。

而这一次给出了预期的方法体

就像我说我不擅长这个，所以如果你能请帮助:)
