copied!<p>After accepting @Erik B's answer and awarding the bounty to him, I found that there was more tweaking necessary to get it to work. I am posting here for the benefit of future SO searchers.</p> <p>The problem I was seeing was that the internal mechanisms of the buttons would assign the image based on the current airplay state. Thus any customizations I made during init would not stick if the Airplay receiver went away, or the state was changed somehow. To solve this, I setup a KVO observation on the button's <code>alpha</code> key. I noticed that the button is always faded in/out which is an animation on <code>alpha</code>.</p> <pre><code>MPVolumeView *volumeView = [[MPVolumeView alloc] initWithFrame:CGRectZero]; [volumeView setShowsVolumeSlider:NO]; for (UIButton *button in volumeView.subviews) { if ([button isKindOfClass:[UIButton class]]) { self.airplayButton = button; // @property retain [self.airplayButton setImage:[UIImage imageNamed:@"airplay.png"] forState:UIControlStateNormal]; [self.airplayButton setBounds:CGRectMake(0, 0, kDefaultIconSize, kDefaultIconSize)]; [self.airplayButton addObserver:self forKeyPath:@"alpha" options:NSKeyValueObservingOptionNew context:nil]; } } [volumeView sizeToFit]; </code></pre> <p>Then I observe the changed value of the buttons <code>alpha</code>. </p> <pre><code>- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { if ([object isKindOfClass:[UIButton class]] && [[change valueForKey:NSKeyValueChangeNewKey] intValue] == 1) { [(UIButton *)object setImage:[UIImage imageNamed:@"airplay.png"] forState:UIControlStateNormal]; [(UIButton *)object setBounds:CGRectMake(0, 0, kDefaultIconSize, kDefaultIconSize)]; } } </code></pre> <p>Don't forget to remove the observer if you destroy the button</p> <pre><code>- (void)dealloc { [self.airplayButton removeObserver:self forKeyPath:@"alpha"]; … } </code></pre> <p>Based on code observation, the button will break if Apple changes the internal view hierarchy of the <code>MPVolumeView</code> to add/remove/alter the views such that a different button comes up. This makes it kind of fragile, so use at your own risk, or come up with a plan b in case this happens. I have been using it for over a year in production with no issues.
