UIButton setTitleColor example in Objective C (iOS).

UIButton setTitleColor

Sets the color of the title to use for the specified state.

- (void)setTitleColor:(UIColor *)color forState:(UIControlState)state

The color of the title to use for the specified state.
The state that uses the specified color. The possible values are described in UIControlState.

Discussion of [UIButton setTitleColor]
In general, if a property is not specified for a state, the default is to use the UIControlStateNormal value. If the UIControlStateNormal value is not set, then the property defaults to a system value. Therefore, at a minimum, you should set the value for the normal state.
