objective-c - 有没有一种简单的方法可以禁止框架中的某些方法？

Question

我想禁止某些方法。例如

+ (MPMusicPlayerController*)iPodMusicPlayer

所以我尝试这样做:

@interface MPMusicPlayerController (Disallowed)
// do never this method cause issues #957 #632 #1463
// read #632 description to detail analysis why code should never use this method while
// applicationMusicPlayer is used
+ (MPMusicPlayerController*)iPodMusicPlayer __attribute__((unavailable));
+ (MPMusicPlayerController*)iPodMusicPlayer __attribute__((deprecated));
@end

但是下面的代码无论如何都会编译而没有任何警告

MPMusicPlayerController * curPlayer = [MPMusicPlayerController iPodMusicPlayer];

有什么想法吗？

编译时间解决方案:

一种方法，只需使用下一个代码:

#pragma GCC poison iPodMusicPlayer

我应该提到SDK61和SDK7不能“毒化”包含“:”的选择器
造成 llvm bug :(

另一种方式:

#import <MediaPlayer/MediaPlayer.h> // import original methods at first
@interface MPMusicPlayerController (Disallowed)
+ (MPMusicPlayerController*)disallowedMethod_iPodMusicPlayer __attribute__((unavailable));
@end

#define iPodMusicPlayer disallowedMethod_iPodMusicPlayer
