IOS 开发学习32 actionSheet的使用

头文件

@interface sheetviewViewController : UIViewController<UIActionSheetDelegate>  

@end

弹出actionSheet

UIActionSheet *actionSheet = [[UIActionSheet alloc]
                                  initWithTitle:_str_title
                                  delegate:self
                                  cancelButtonTitle:@"取消"
                                  destructiveButtonTitle:nil
                                  otherButtonTitles:nil];


    [actionSheet addButtonWithTitle:@"一个选项"];

    actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
    [actionSheet showInView:self.view];

定义重写方法

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
    if(buttonIndex<1)return;
}
- (void)actionSheetCancel:(UIActionSheet *)actionSheet{
    NSLog(@"cancel");
}
-(void)actionSheet:(UIActionSheet *)actionSheet didDismissWithButtonIndex:(NSInteger)buttonIndex{
    NSLog(@"didDismiss");
}
-(void)actionSheet:(UIActionSheet *)actionSheet willDismissWithButtonIndex:(NSInteger)buttonIndex{
    NSLog(@"willDismiss");
}
