Creating a Label via a method in a class - iphone

Question

I am slowly developing a custom button (while learning how to implement classes etc).
I have a ViewController, which imports a SuperButton.h (UIControl) and then creates an instance of the SuperButton. (This works, as proved by a NSLog.)
But I cannot get the method in SuperButton to display a Label.
I think this might have something to with the '.center' value or the 'addSubview' command?
I would really appreciate your help. Thanks.
Here is my SuperButton.m code:
#import "SuperButton.h"
#implementation SuperButton
#synthesize firstTitle;
#synthesize myLabel;
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
}
return self;
}
- (void) shoutName{
NSLog(#"My name is %#", firstTitle);
self.backgroundColor = [UIColor blueColor];
CGRect labelFrame = CGRectMake(0.0f, 0.0f, 100.0f, 50.0f);
self.myLabel = [[UILabel alloc] initWithFrame:labelFrame];
self.myLabel.text = #"Come on, don't be shy.";
self.myLabel.font = [UIFont italicSystemFontOfSize:14.0f];
self.myLabel.textColor = [UIColor grayColor];
self.myLabel.center = self.center;
[self addSubview:self.myLabel];
}
Here is the code in my ViewController:
- (void) makeButton{
SuperButton *button1 = [[SuperButton alloc] init];
button1.firstTitle = #"Mr. Ploppy";
[button1 shoutName];
}
(EDIT:) Just in case, here's the SuperButton.h code:
#import <UIKit/UIKit.h>
#interface SuperButton : UIControl
#property (nonatomic, strong) NSString *firstTitle;
#property (nonatomic, strong) UILabel *myLabel;
- (void) shoutName;
#end

I found an answer elsewhere.
I needed to addSubview the 'button'. My working code now looks like this:
- (void) makeButton{
SuperButton *button1 = [[SuperButton alloc] init];
button1.firstTitle = #"Mr. Ploppy";
[button1 shoutName];
[self.view addSubview:button1.myLabel];
[self.view sendSubviewToBack:button1.myLabel];
}

You are initializing your button not with initWithFrame: method, but with simple init. This makes the button of CGRectZero size. Change this line:
SuperButton *button1 = [[SuperButton alloc] init];
to this:
SuperButton *button1 = [[SuperButton alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 100.0f, 50.0f)];
or add a call to setFrame: after initializing your button.
