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)
(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
- }
- }
