如何解决有关未实现'UIActionSheetDelegate‘协议的警告

Question

下面是我的.h代码

@interface ROSettingViewController : UITableViewController
{
    UISwitch                *switchCtl;
    UISwitch                *switchCtl1;
    NSArray                 *dataSourceArray;
}

@property (nonatomic, retain, readonly) UISwitch *switchCtl;
@property (nonatomic, retain, readonly) UISwitch *switchCtl1;
@property (nonatomic, retain) NSArray *dataSourceArray;

- (void)dialogOKCancelAction;
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex;

@end

Answer 1

您是否尝试过声明您的控制器遵守UIActionSheetDelegate协议？

@interface ROSettingViewController : UITableViewController<UIActionSheetDelegate>

Answer 2

你很可能会说，在ROSettingViewController.m:321上，

myActionSheet.delegate = self;

而没有指定您的VC实现UIActionSheetDelegate协议
