i am using xcode4 and storyboard to create an application form. I would like to add check button and found using NSButton is the best way, but I could not find NSButton in the object library. Would you please tell me how to find it?
NSButton is cocoa class and available on MacOS, not iOS. iOS does not have standard check box so you'll have to use UIButton with custom images for selected/deselected state instead of that.
Or (may be better) you can use standard UISwitch control which serves similar purpose
