UIButton setTitle forState example in Objective C (iOS).

UIButton setTitle forState

Sets the title to use for the specified state.

- (void)setTitle:(NSString *)title forState:(UIControlState)state

Parameters of [UIButton setTitle forState]
The title to use for the specified state.
The state that uses the specified title. The possible values are described in UIControlState.

Discussion of [UIButton setTitle forState]
Use this method to set the title for the button. The title you specify derives its formatting from the button’s associated label object. If you set both a title and an attributed title for the button, the button prefers the use of the attributed title over this one.

At a minimum, you should set the value for the normal state. If a title is not specified for a state, the default behavior is to use the title associated with the UIControlStateNormal state. If the value for UIControlStateNormal is not set, then the property defaults to a system value.

[backbtn addTarget:self action:@selector(backBtnClicked) forControlEvents:UIControlEventTouchUpInside];
