警告框样式(带输入框)

今天写项目要用到警告框带输入框的,于是就自己做了个小demo.

效果图大体如下:


下面简单介绍一下UIAlertView

alertViewStyle 属性有以下三种选项:

 UIAlertViewStylePlainTextInput 添加一个普通输入框 
 UIAlertViewStyleSecureTextInput   密码输入框
 UIAlertViewStyleLoginAndPasswordInput  普通输入框加密码输入框

下面分别来看看这三种属性的效果:

UIAlertViewStylePlainTextInput          UIAlertViewStyleSecureTextInput

( UIAlertViewStylePlainTextInput )                                (UIAlertViewStyleSecureTextInput)

UIAlertViewStyleLoginAndPasswordInput

(UIAlertViewStyleLoginAndPasswordInput)

下面附上自己写的部分关键代码:

#pragma mark 弹出菜单

- (IBAction)showMenu:(id)sender {
    
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"修改Webservice请求地址"
                                                        message:@"请输入地址:(http://192.168.6.12)"
                                                       delegate:self cancelButtonTitle:@"确定"
                                              otherButtonTitles:@"取消", nil];
    [alertView setAlertViewStyle:UIAlertViewStylePlainTextInput];
    
    [alertView show]; 
    //背景View
    UIView *additonBackgroundView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, alertView.frame.size.width-30, alertView.frame.size.height-20)];
    additonBackgroundView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"bag3.jpg"]]; //添加背景图片

    [alertView insertSubview:additonBackgroundView atIndex:1];

}

#pragma mark   获得输入框里的值
- (void) alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{
    NSString *buttonTitle = [alertView buttonTitleAtIndex:buttonIndex];
    if ([buttonTitle isEqualToString:@"确定"]){
          UITextField *tf=[alertView textFieldAtIndex:0];//获得输入框
        NSString * requestedURL=tf.text;//获得值

    }
}
