Expected a type error
提问by Nikolai Ruhe
So I created this method:
所以我创建了这个方法：
- (void)addToViewController:(SecViewController *)controller
didFinishEnteringItem:(NSString *)item;` <br>
And Xcodekeeps giving me Expected a typeerror at SecViewController *. What does that mean? SecViewControlleris not a type?
并且Xcode一直Expected a type在SecViewController *给我错误。这意味着什么？SecViewController不是一个类型？
回答by Nikolai Ruhe
You have to declare SecViewController:
你必须声明SecViewController：
@class SecViewController;
... at the top of your header.
...在标题的顶部。
Note: Don't just #importall used headers. This just worsens your header dependencies.
注意：不要只是#import所有使用的标题。这只会恶化您的标头依赖性。
