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)
(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
}
}
