提示框UIAlertView/UIAlertViewController的简单使用

IOS 8 前

  

UIAlertView创建提示框

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.25 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

       
        UIAlertView *alertV = [[UIAlertView alloc]initWithTitle:@"您的幸运号码是:" message:@"1,2,3,4,5,6" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:nil, nil];
       
        //显示
        [alertV show];
       

    });

IOS 8 

UIAlertViewController

1、设置代理调用

 //执行代理方法
    if ([self.delegate respondsToSelector:@selector(modalWithAlertController:)]) {
        //有方法则执行
        [self.delegate modalWithAlertController:self];

    }

2、控制器实现

-(void)modalWithAlertController:(CZWheelVIew *)alertcontroller
{
    //创建提示框控制器
    UIAlertController *alertC = [UIAlertController alertControllerWithTitle:@"您的幸运号码是:" message:@"1,2,3,4,5,6" preferredStyle:UIAlertControllerStyleAlert];
   
    //创建一个动作
    UIAlertAction *alertA = [UIAlertAction actionWithTitle:@"确认" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        //继续匀速旋转
        [self.wheelView startRotate];
       
    }];
   
    //动作添加给提示框控制器
    [alertC addAction:alertA];
   
    //控制器弹出控制器
    [self presentViewController:alertC animated:YES completion:nil];

}
