UIAlertView에 UITextField 추가( UIAlertView Customize, IOS )

구글에서 찾은건데 약간 버그가 있어서, 수정했다.

//AlertPrompt.h
#import <Foundation/Foundation.h>

@interface AlertPrompt : UIAlertView
{
    UITextField *textField;
}
@property (nonatomic, retain) UITextField *textField;
@property (readonly) NSString *enteredText;
- (id)initWithTitle:(NSString *)title message:(NSString *)message delegate:(id)delegate cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitle:(NSString *)okButtonTitle;
@end


//AlertPrompt.mm
#import "AlertPrompt.h"

@implementation AlertPrompt
@synthesize textField;
@synthesize enteredText;
- (id)initWithTitle:(NSString *)title message:(NSString *)message delegate:(id)delegate cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitle:(NSString *)okayButtonTitle
{
NSString *msg = [ NSString stringWithFormat:@"\n%@", message ];
    if (self = [super initWithTitle:title message:msg delegate:delegate cancelButtonTitle:cancelButtonTitle otherButtonTitles:okayButtonTitle, nil])
    {
        UITextField *theTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 40.0, 260.0, 25.0)];
        [theTextField setBackgroundColor:[UIColor whiteColor]];
        [self addSubview:theTextField];
        self.textField = theTextField;
        [theTextField release];
        CGAffineTransform translate = CGAffineTransformMakeTranslation(0.0, 130.0);
        [self setTransform:translate];
    }
    return self;
}
- (void)show
{
    [textField becomeFirstResponder];
    [super show];
}
- (NSString *)enteredText
{
    return textField.text;
}
- (void)dealloc
{
    [textField release];
    [super dealloc];
}
@end
