iPhone Tutorial ~ Inserting UITextFields into UIAlertViews Automatically

So I noticed a lot of people are trying to get UITextFields into UIAlertViews by manually generating one and fixing the coordinates, etc. But What a lot of people don't know is that Apple has an easier (non-documented) way that they do this, in apps like iTunes, etc. 

// First Let's Make a UIAlertView Like Normal..

UIAlertView *myAlert = [[UIAlertView alloc] init];

[myAlert setTitle:@"ALERT TITLE"];

[myAlert setMessage:@"HELLO WORLD"];

[myAlert setDelegate:self];

[myAlert setTag:1];

[myAlert addTextFieldWithValue:@"" label:@"ADD LABEL HERE"];

[myAlert addButtonWithTitle:@"OK"];

[myAlert addButtonWithTitle:@"Cancel"];

// Now Let's Use Apple's Special Way of Adding a UITextField with little to no work

txtInput = [myAlert textFieldAtIndex:0];

txtInput.clearButtonMode = UITextFieldViewModeWhileEditing;

txtInput.keyboardType = UIKeyboardTypeDefault;

txtInput.keyboardAppearance = UIKeyboardAppearanceAlert;

txtInput.autocorrectionType = UITextAutocorrectionTypeNo;

txtInput.secureTextEntry = NO;

[myAlert show];

[myAlert release];

Clear Button Mode adds the little "X" while typing to clear the UITextField. Keyboardtype obviously sets the type of keyboard. Here are your options for that:

UIKeyboardTypeDefault

Use the default keyboard for the current input method.

Available in iPhone OS 2.0 and later.

Declared in UITextInputTraits.h.

UIKeyboardTypeASCIICapable

Use a keyboard that displays standard ASCII characters.

Available in iPhone OS 2.0 and later.

Declared in UITextInputTraits.h.

UIKeyboardTypeNumbersAndPunctuation

Use the numbers and punctuation keyboard.

Available in iPhone OS 2.0 and later.

Declared in UITextInputTraits.h.

UIKeyboardTypeURL

Use a keyboard optimized for URL entry. This type features “.”, “/”, and “.com” prominently.

Available in iPhone OS 2.0 and later.

Declared in UITextInputTraits.h.

UIKeyboardTypeNumberPad

Use a numeric keypad designed for PIN entry. This type features the numbers 0 through 9 prominently. This keyboard type does not support auto-capitalization.

Available in iPhone OS 2.0 and later.

Declared in UITextInputTraits.h.

UIKeyboardTypePhonePad

Use a keypad designed for entering telephone numbers. This type features the numbers 0 through 9 and the “*” and “#” characters prominently. This keyboard type does not support auto-capitalization.

Available in iPhone OS 2.0 and later.

Declared in UITextInputTraits.h.

UIKeyboardTypeNamePhonePad

Use a keypad designed for entering a person’s name or phone number. This keyboard type does not support auto-capitalization.

Available in iPhone OS 2.0 and later.

Declared in UITextInputTraits.h.

UIKeyboardTypeEmailAddress

Use a keyboard optimized for specifying email addresses. This type features the “@”, “.” and space characters prominently.

Available in iPhone OS 2.0 and later.

Declared in UITextInputTraits.h.

and Finally, secureTextEntry allows you to change the characters to dots if you are entering a password.

And of course, you can add more than one UITextField to a UIAlertView, so this should please all of your username/password needs.
