Adding TextField to UIAlertView

提问by shajem

I need to add a TextFieldto an UIAlertView. I understand that apple discourage this approach. So is there any library that i could make use of to add a TextFieldto a UIAlertViewlook-alike frame ?

我需要将 a 添加TextField到UIAlertView. 我知道苹果不鼓励这种方法。那么是否有任何库可以用来将 a 添加TextField到UIAlertView相似的框架中？

For iOS5:

对于 iOS5：

UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"Title" message:@"Please enter someth" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
av.alertViewStyle = UIAlertViewStylePlainTextInput;
[av textFieldAtIndex:0].delegate = self;
[av show];

Also, you 'll need to implement UITextFieldDelegate, UIAlertViewDelegateprotocols.

此外，您将需要实现UITextFieldDelegate，UIAlertViewDelegate协议。

Unfortunately the only official API for this is iOS 5 and up, it's a property called alertViewStylewhich can be set to the following parameters:

不幸的是，唯一的官方 API 是 iOS 5 及更高版本，它是一个被调用的属性alertViewStyle，可以设置为以下参数：

UIAlertViewStyleDefault
UIAlertViewStyleSecureTextInput
UIAlertViewStylePlainTextInput
UIAlertViewStyleLoginAndPasswordInput

UIAlertViewStylePlainTextInputbeing the one you want.

UIAlertViewStylePlainTextInput成为你想要的那个。

Messing with the view hierarchy as described above is strongly discouraged by Apple.

Apple 强烈不鼓励使用上述视图层次结构。

I'm using BlockAlertsAndActionSheetsinstead of the Apple components for AlertViews and ActionSheets as I prefer the blocks-approach. Also contains a BlockTextPromptAlertViewin the source, which might be what you want. You can replace the images of that control to get the Apple-style back.

我使用BlockAlertsAndActionSheets而不是 Apple 组件用于 AlertViews 和 ActionSheets，因为我更喜欢块方法。BlockTextPromptAlertView源中还包含一个，这可能是您想要的。您可以替换该控件的图像以恢复 Apple 风格。

Try something like this:

尝试这样的事情：

UIAlertView *alert = [[[UIAlertView alloc] initWithTitle:@"Title"
                                                 message:@"\n\n"
                                                delegate:self
                                       cancelButtonTitle:@"Cancel"
                                       otherButtonTitles:@"Save", nil] autorelease];
CGRect rect = {12, 60, 260, 25};
UITextField *dirField = [[[UITextField alloc] initWithFrame:rect] autorelease];
dirField.backgroundColor = [UIColor whiteColor];
[dirField becomeFirstResponder];
[alert addSubview:dirField];

[alert show];

As of iOS 8 UIAlertViewhas been deprecated in favor of UIAlertController, which adds support for adding UITextFields using the method:

从 iOS 8UIAlertView开始，已弃用UIAlertController，这增加了对UITextField使用以下方法添加s 的支持：

- (void)addTextFieldWithConfigurationHandler:(void (^)(UITextField *textField))configurationHandler;

See this answerfor an example.

有关示例，请参阅此答案。

You can try:

你可以试试：

UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:@"Your title here!" message:@"this gets covered" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"OK", nil];
UITextField *myTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)];
[myTextField setBackgroundColor:[UIColor whiteColor]];
[myAlertView addSubview:testTextField];
[myAlertView show];
[myAlertView release];

first of All Add UIAlertViewDelegate into ViewController.h File like

首先将 UIAlertViewDelegate 添加到 ViewController.h 文件中，例如

#import <UIKit/UIKit.h>

@interface UIViewController : UITableViewController<UIAlertViewDelegate>

@end

and than Add Below Code where you wants to alert Display,

然后在你想要提醒显示的地方添加下面的代码，

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Title"
                                            message:@"Message"
                                           delegate:self
                                  cancelButtonTitle:@"Done"
                                  otherButtonTitles:nil];
alert.alertViewStyle = UIAlertViewStylePlainTextInput;
[alert show];

and it's delegate method which returns what input of UItextField

它是委托方法，它返回 UItextField 的输入

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
NSLog(@"%@", [alertView textFieldAtIndex:0].text);
}
