自定义Airplay按钮的外观 [英] Customize the Airplay button's appearance

问题描述

我使用标准渐变叠加（在photoshop中完成）使按钮在我的应用中看起来更漂亮。我添加了一个Airplay按钮，但美学不匹配。

I use a standard gradient overlay (done in photoshop) to make buttons look nicer in my app. I added an Airplay button, but the aesthetics are not matching.

我真的想在它上面放一个渐变层使它匹配，但我能找到的任何东西只显示如何用png，不是现有的UIView。如果不是渐变层，我只需要任何方式来改变Apple airplay按钮的外观，同时保持其功能完好无损。

I really want to put a gradient layer over it so it matches, but anything I can find only shows how to do this with a png, not an existing UIView. If not the gradient layer, I just need someway, any way, to change the appearance of the Apple airplay button while keeping its functionality intact.

设置代码很简单：

MPVolumeView *volumeView = [[MPVolumeView alloc] initWithFrame:frame];
[volumeView setShowsVolumeSlider:NO];
[bottomPanel addSubview:volumeView];

如何才能看到它的外观以匹配我的控件？

How can I get the appearance of this to match my controls?

推荐答案

我认为自iOS 6以来有更好的解决方案：
使用

I think there's a better solution to this since iOS 6: Use

- （void）setRouteButtonImage：（UIImage *）image forState：（UIControlState）state;

在MPVolumeView上。

on MPVolumeView.
