I’ve set an image for a button. Even though the image has a transparent background, there is always a white edge around the button. I’ve tried a lot of things (see codes below), how do I get rid of it?

[myButton setBackgroundImage:[UIImage imageNamed:@"button.png"] forState:UIControlStateNormal];
[myButton setBackgroundColor:[UIColor clearColor]];

[[myButton layer] setBackgroundColor:[[UIColor clearColor] CGColor]];
[[myButton layer] setBorderWidth:0];

I’m not allowed to upload pictures yet, but the result can be found here: https://docs.google.com/open?id=0B9d-ZrsbiU3IY2RPcXlKNlh1Q1U

As you can see, that white edge is very annoying.

    You need to create a button of type UIButtonTypeCustom.

    If you’re creating it programatically then use buttonWithType:UIButtonTypeCustom. If you’re creating it in IB then select “Custom” as the type from the drop down.

    This will mean that the standard white is not drawn.
