UIButton setBackgroundImage example objc

setBackgroundImage:forState:

Sets the background image to use for the specified button state.

- (void)setBackgroundImage:(UIImage *)image forState:(UIControlState)state

Parameters

image

The background image to use for the specified state.

state

The state that uses the specified image. The values are described in UIControlState.

Discussion

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. (setBackgroundImage:forState:)

    NSString            *title = @"My button title";
