How do I use If-Else statements to change a UIImage

[NSpehler]

Hey folks!

I'm having an issue on my iPhone application.

I want my UIImage to change if a user press on it. I know how to do that :

- (IBAction)buttonClicked:(id)sender {
		UIImage *img = [UIImage imageNamed:@"Version.png"];
		[sender setImage:img forState:UIControlStateNormal];
}

But, my problem is that I'd like my UIImage to change back to the first image if we already pressed on the UIImage.

Here is my code :

- (IBAction)buttonClicked:(id)sender {
	
	if ([UIImage imageNamed:@"Version.png"]) 
        {
		UIImage *img = [UIImage imageNamed:@"VersionTouched.png"];
		[sender setImage:img forState:UIControlStateNormal];
	}
	else if ( [UIImage imageNamed:@"VersionTouched.png"]) 
        {
		UIImage *img = [UIImage imageNamed:@"Version.png"];
		[sender setImage:img forState:UIControlStateNormal];
	}
}

Hope you can edit my If-Else statements in order to be able to do that...

Thanks!

define your UIImage img in your .h resource file.

then you should use the following:

- (IBAction)buttonClicked:(id)sender {
	
	if (img == [UIImage imageNamed:@"Version.png"]) 
        {
		img = [UIImage imageNamed:@"VersionTouched.png"];
		[sender setImage:img forState:UIControlStateNormal];
	}
	else if (img == [UIImage imageNamed:@"VersionTouched.png"]) 
        {
		img = [UIImage imageNamed:@"Version.png"];
		[sender setImage:img forState:UIControlStateNormal];
	}
}

Please tell me if something is unclear or not working.

Thanks for your answer,
Unfortunatly, it's not working...

Inside my .h file I have :

@interface MyViewController : TTViewController {
	IBOutlet UIImage *img;
}

- (IBAction)buttonClicked:(id)sender;

And your code in the .m...

In my nib file, the button is connected to 'buttonClicked:'...

Any idea ?

Try to change the UIImage from your .h to an UIImageView

So you'll write this in your .h

@interface MyViewController : TTViewController {
	IBOutlet UIImageView *img;
}

- (IBAction)buttonClicked:(id)sender;

No luck...
It's not even updating from Version.png to VersionTouched.png.

Maybe the fact that my UIImage is in a Custom UIButton...?

isn´t it

if (img.image == [UIImage imageNamed:@"Version.png"])

?

Correct me if im wrong :P
