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]
title
The title to use for the specified state.
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.

Discussion

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

Example for ( setTitle:forState: )
{
    NSString            *title = @"My button title";
    UIColor              *titleColor = [UIColor colorWithWhite:0.5f alpha:1.0f];
    UIImage             *bgImage = [UIImage imageNamed:@"yourImage.png"];

    UIImage             *highlightedBgImage = [UIImage imageNamed:@"yourImage.png"];

    UIButton            *button = [UIButton buttonWithType:UIButtonTypeCustom];

    

    // Create button.

    //

    button.bounds = CGRectMake( 0.0f, 0.0f, bgImage.size.width, bgImage.size.height );

    button.titleLabel.font = [UIFont fontWithName:@"HelveticaNeue-Medium" size:14.0f];

    button.titleLabel.adjustsFontSizeToFitWidth = YES;

    button.titleLabel.minimumFontSize = 10.0f;

    [button setTitleColor:titleColor forState:UIControlStateNormal];

    [button setTitleColor:titleColor forState:UIControlStateHighlighted];

    [button setTitle:title forState:UIControlStateNormal];

    [button setTitle:title forState:UIControlStateHighlighted];

    [button setBackgroundImage:bgImage forState:UIControlStateNormal];

    [button setBackgroundImage:highlightedBgImage forState:UIControlStateHighlighted];

    // You must specify your target object and action selector here.
    //
