Adding TextField to UIAlertView

Question

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

For 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, UIAlertViewDelegate protocols.

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

UIAlertViewStyleDefault
UIAlertViewStyleSecureTextInput
UIAlertViewStylePlainTextInput
UIAlertViewStyleLoginAndPasswordInput

UIAlertViewStylePlainTextInput being the one you want.

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

I have to create this for iOS 4 and 5. So are you aware of any other library where i could use – shajem Apr 01 '12 at 08:01

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

Project on gitgub

Tutorial which gets you started

Example:

- (IBAction)newFolder:(id)sender {
    id selfDelegate = self;
    UITextField                 *textField;
    BlockTextPromptAlertView    *alert = [BlockTextPromptAlertView  promptWithTitle :@"New Folder"
                                                                    message         :@"Please enter the name of the new folder!"
                                                                    textField       :&textField];
    [alert setCancelButtonWithTitle:@"Cancel" block:nil];
    [alert addButtonWithTitle:@"Okay" block:^{
        [selfDelegate createFolder:textField.text];
    }];
    [alert show];
}

- (void)createFolder:(NSString*)folderName {
    // do stuff
}

Can you show me an example that uses `BlockTextPromptAlertView `. I am under the impression that developers are not allowed to add any textfields etc to UIAlertView. – shajem Apr 01 '12 at 07:15
You're right with your impression. That's why BlockAlertsAndActionSheets is **not** using UIAlertView at all, it's a completely independent implementation without any private API's being used. I don't have access to my sources right now, but can update my answer with an code sample in some hours. – Andy Friese Apr 01 '12 at 08:05
Is there a way where i could stop the animation ? (Th bouncing effect) – shajem Apr 02 '12 at 01:49
If you would like to change the way the control is animated, try searching for `animateWithDuration` in BlockAlertView.m and BlockTextPromptAlertView.m – Andy Friese Apr 02 '12 at 06:19

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

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

See this answer for an example.

Try something like this:

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];

I think Apple discourage your approach. – shajem Apr 01 '12 at 07:13 — shajem, Apr 01 '12 at 07:13

You can try:

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];

Yes, your code works. But Apple discourages this approach, as its using private APIs. SO is there any other way i could solve this ? – shajem Apr 01 '12 at 07:17
@anonymous The OP refers to that sentence from the docs: The view hierarchy for this class is private and must not be modified. – Andy Friese Apr 01 '12 at 08:53

first of All Add UIAlertViewDelegate into ViewController.h File like

#import <UIKit/UIKit.h>

@interface UIViewController : UITableViewController<UIAlertViewDelegate>

@end

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

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

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

adding to answer from 'Shmidt', the code to capture text entered in UIAlertView is pasted below (thank you 'Wayne Hartman' Getting text from UIAlertView)

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 1) {
        self.userNumber = [alertView textFieldAtIndex:0].text;
        if (self.userNumber) {
            // user enetered value
            NSLog(@"self.userNumber: %@",self.userNumber);
        } else {
            NSLog(@"null");
        }

    }
}

refer this... http://iosdevelopertips.com/undocumented/alert-with-textfields.html this is private api and if you use it for app in appstore it might get rejected but it is fine for enterprise development.

Thank you for your reply, but i am hoping to publish my app to appstore :S – shajem Apr 01 '12 at 07:16
than I won't advise you should implement this. – Ankit Srivastava Apr 01 '12 at 07:19
