“指定自有代表的警告
原标题:"Incompatible pointer..." warning on assigning delegate to self

我的习俗等级为可调通的口号,其定义如下:

#import <UIKit/UIKit.h>

@protocol CustomDelegate <NSObject>
@optional
-(NSInteger)numberOfRows;
@end

@interface CustomTV : UITableView <UITableViewDelegate, UITableViewDataSource>{  
    id<CustomDelegate> *del;
}
@property (nonatomic, assign)    id<CustomDelegate> *del;
@end

现在,在其他几类人中,我立即播放这一习俗电视,并指派代表自行:

    CustomTV *tbl = [[CustomTV alloc] initWithFrame:CGRectMake(0, 0, 200, 400) style:UITableViewStylePlain];
    tbl.del = self;

为什么我获得“不相容的点子”。

我在头脑中确实遵守习俗规范。

最佳回答

您宣布代表为反对点的协调人。 <代码>id已经宣布为物体的点子,从而消除了饥饿。

@interface CustomTV : UITableView <UITableViewDelegate, UITableViewDataSource>{  
    id<CustomDelegate> del;
}
@property (nonatomic, assign)    id<CustomDelegate> del;
@end
