Adding integers and displaying in a UILabel

Adding integers and displaying in a UILabel

I am working on a scoreboard of sorts. The player can adjust three
different values (gear, level, and bonuses) that when added should provide
a total strength. Each of these values is currently being output as an
integer and a UILabel displays its' respective integer. I cannot figure
out how to add all three integers and then display them on a UILabel. I am
currently developing for iOS 7 but I don't imagine this to be terribly
different for current supported OS's. Any help is greatly appreciated.
