iOS笔记之UIKit_UIAlertView、UIActionSheet

//首先必须继承协议

@interface TRViewController : UIViewController<UIAlertViewDelegate,UIActionSheetDelegate>

 

 

//UIAlertView功能实现

- (IBAction)clicked:(id)sender {

    UIButton *btn = sender;

     //设置tag值

    if (btn.tag==0) {

        UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"Title" message:@"message" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];

         // 设置AlertView样式

        [alertView setAlertViewStyle:UIAlertViewStyleLoginAndPasswordInput];

        //把alertView里面的TF取出来

          UITextField *nameTF = [alertView textFieldAtIndex:0];

          UITextField *pwTF = [alertView textFieldAtIndex:1];

          nameTF.text = @"haha";

          pwTF.text = @"adfadsf";

 

        //弹窗显示

        [alertView show];

       }else{

      //UIActionSheet初始化

         UIActionSheet *as = [[UIActionSheet alloc]initWithTitle:@"Title" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"destructive" otherButtonTitles:@"呵呵", nil];

        [as showInView:self.view];

    }

}

 

    //AlertView点击事件

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{

    NSLog(@"%ld",(long)buttonIndex);

   //第一个按钮

        if (buttonIndex==1) {//确定

        UITextField *nameTF = [alertView textFieldAtIndex:0];

        UITextField *pwTF = [alertView textFieldAtIndex:1];

        NSLog(@"%@  %@",nameTF.text,pwTF.text);

    }else{//取消

    }

}

//ActionSheet点击事件

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{

    NSLog(@"%ld",(long)buttonIndex);

}
