ios基础控件UIAlertView与UIActionSheet

1.UIAlertView

首先来看下UIAlertView的实现效果图：

第一步通过点击外部按钮弹出提醒对话框

- (IBAction)showAlertView:(id)sender {
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"标题" message:@"提醒内容" delegate:self cancelButtonTitle:@"NO" otherButtonTitles:@"YES", nil];
    [alert show];
}

第二步实现对两个按钮点击事件的响应

#pragma mark - UIAlertViewDelegate
- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    NSLog(@"%ld", buttonIndex);
}

2.UIActionSheet

首先来看下UIActionSheet实现的效果图

第一步给外部的按钮增加点击事件弹出操作表

- (IBAction)openActionSheet:(id)sender {
    UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"标题" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"破坏" otherButtonTitles:@"其它", nil];
    
    [sheet showInView:self.view];
}

第二步监听各个按钮点击事件

#pragma mark - UIActionSheetDelegate
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
    NSLog(@"%ld", buttonIndex);
    NSString *title = [actionSheet buttonTitleAtIndex:buttonIndex];
    NSLog(@"您点击了：%@", title);
}

注：以上两个控件在监听内部按钮点击响应事件时，都需要添加代理协议：

@interface OtherViewController ()


@end
