MPMusicPlayerController和setNowPlayingItem [英] MPMusicPlayerController and setNowPlayingItem

问题描述

我正在使用 MPMusicPlayerController ，特别是与 setNowPlayingItem 协议配合使用，并且用于 cydia 。但是当我提出问题时，我会遇到一些问题和theos的警告。似乎某些协议和方法不起作用，我收到这样的警告：

I'm using MPMusicPlayerController, specifically with setNowPlayingItem protocol and it's for cydia. But I have some issues and theos' warning when i make. It seems that some of the protocols and methods are not working and I receive some warning like this:

Tweak.xm:177: warning: ‘MPMusicPlayerController’ may not respond to ‘-skipToPreviousItem’
Tweak.xm:188: warning: ‘MPMusicPlayerController’ may not respond to ‘-pause’
Tweak.xm:193: warning: ‘MPMusicPlayerController’ may not respond to ‘-play’
Tweak.xm:201: warning: ‘MPMusicPlayerController’ may not respond to ‘-skipToNextItem’
Tweak.xm:317: warning: ‘MPMusicPlayerController’ may not respond to ‘-setNowPlayingItem:’

有人有想法吗？我已经在原型中输入了协议

Have anyone some ideas? I enter the protocol already in prototype
