You can use UIAlertViewStylePlainTextInput of UIAlertView to get text field in alertView :

UIAlertView *alert=[[UIAlertView alloc] initWithTitle:@"Enter Data" message:@"\n\n\n" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:@"Ok", nil];

// Set alertView style
alert.alertViewStyle = UIAlertViewStylePlainTextInput;

textUserName =[alert textFieldAtIndex:0];

// Then customize your textField
textUserName.placeholder = @"Name";
textUserName.autocorrectionType = UITextAutocorrectionTypeNo;
textUserName.textAlignment=UITextAlignmentLeft;
textUserName.userInteractionEnabled = YES;
textUserName.enabled = YES;
textUserName.enablesReturnKeyAutomatically= NO;
textUserName.clearsOnBeginEditing = NO;
textUserName.borderStyle = UITextBorderStyleRoundedRect;
textUserName.keyboardType = UIKeyboardTypeDefault;

[alert show];

In this no need of setting delegate separately..
