Question

I want to create a UIButton with the normal black gradient theme in iOS. I’ve looked at the documentation and can’t seem to figure out how to do this. When I create the button, I get a rounded rect button with no color.

Here is my code:

UIButton* leagueTeamButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

Any suggestions on how I can add the standard themed black gradient to the button?

Make one (or two, if you want it change appearance when press down) in Photoshop – or any image processing software – and put into your project’s resource folder, use the following code to add the image as a UIButton:

UIButton *yourButton=[UIButton buttonWithType:UIButtonTypeCustom];
[yourButton setFrame:CGRectMake(0,0,10,10)];
[yourButton addTarget:self action:@selector(functionYouWantToCall:) forControlEvents:UIControlEventTouchUpInside];

[yourButton setImage:[UIImage imageNamed:@"imageNormalState.png"] forState:UIControlStateNormal];
[yourButton setImage:[UIImage imageNamed:@"imageWhenPressDown.png"] forState:UIControlStateHighlighted]; // option if you want to display another image (i.e. darker one) when user press the button
