Textfield in alertview not working in ios7?

Question

I have an application in which I'm using a specific design for a reason. I put a text field in an alert view above an otherbutton with a background image. Everything is working fine in ios 6 version.

UIAlertView *av=[[UIAlertView alloc] initWithTitle:@"fdhdj" message:@" hdfjkhfjkhdk" delegate:self cancelButtonTitle:@"ok" otherButtonTitles:@" ",@"cancel",nil];
     av.alertViewStyle = UIAlertViewStylePlainTextInput;
 namefield = [[UITextField alloc] initWithFrame:CGRectMake(10.0,43.0, 264.0, 44.0)];
    namefield.borderStyle = UITextBorderStyleNone;
    namefield.background = [UIImage imageNamed:@"text_field_default.png"];
    namefield.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    namefield.textAlignment = UITextAlignmentCenter;
    //[namefield setBackgroundColor:[UIColor whiteColor]];
    [av addSubview:namefield];
    [namefield release];
    av.tag=12;
    av.delegate=self;  
    [av show];

    [av release];

But now in ios 7, I heard you can't easily alter the view hierarchy of a UIAlertView. One alternative for this case is to set

alert.alertViewStyle = UIAlertViewStylePlainTextInput

But can we add that text field in wherever we want? As in my case above the first otherbutton.can anybody help me?

Why not do your own UIView hierarchy that you have complete control over instead of fooling with UIAlertView. [Apple's documentation for UIAlertView states](https://developer.apple.com/library/ios/documentation/uikit/reference/UIAlertView_Class/UIAlertView/UIAlertView.html#//apple_ref/doc/uid/TP40006802-CH3-DontLinkElementID_2): "The view hierarchy for this class is private and must not be modified.", which is what you're doing by adding subviews. — Michael Dautermann, Oct 07 '13 at 06:33

 UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Enter Student Name" message:@"" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Save",nil];

 [alertView setAlertViewStyle:UIAlertViewStylePlainTextInput];
 [alertView show];

This is my component to support addSubview with alertView in iOS7.

CXAlertView - Custom alert-view which allow you to add view as main content.

The simple answer to your question is NO, you can't change anything in this testField for the UIAlertViewStylePlainTextInput and you shouldn't.

This is from Apple:

The UIAlertView class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified.

And unfortunately what you heard I heard you can't easily alter the view hierarchy of a UIAlertView is wrong, you cannot alter the view hierarchy of a UIAlertView in iOS7 at all.

There are a good alternative on the web, you can check in cocoacontrols.com

You can't easily alter the view hierarchy of a UIAlertView in iOS 7. (Nor should you; the documentation specifically tells you not to.) Head over to the developer forums to see a long discussion about it.

One alternative in your case is to set alert.alertViewStyle = UIAlertViewStylePlainTextInput; This will add a text field for you. You can access it in the UIAlertView delegate callback by using UITextField *textField = [alertView textFieldAtIndex:0];.
