Question

我是Objective-C编程的新手，我想对iOS.app进行VLC的简单调整，但我无法编译。这是我的代码：

#import <UIKit/UIKit.h>

%hook VLCMovieViewController

-(IBAction)playPause
{
    if([_mediaPlayer isPlaying]) {
        UIAlertView *pause = [[UIAlertView alloc] initWithTitle:@"PAUSED" message:@"Your movie is paused" delegate:nil cancelButtonTitle:nil otherButtonTitles:@"OK !", nil];
        [_listPlayer pause];
        [pause show];
        [pause release];
    }
    else
    {
        UIAlertView *play = [[UIAlertView alloc] initWithTitle:@"PLAYING" message:@"Your movie is playing" delegate:nil cancelButtonTitle:nil otherButtonTitles:@"OK !", nil];
        [_listPlayer play];
        [play show];
        [play release];
    }
}

%end

我的代码中没有发现任何错误，但是当我尝试编译时，theos会给我一个错误：

Preprocessing Tweak.xm...

你有什么线索可以让它发挥作用吗？

非常感谢提前

您不需要对Theos使用IBAction，因为您不使用Interface Builder。 IBAction只是告诉Xcode和Interface Builder将UI元素链接到代码的一种方法。替换 - （IBAction）playPause by - （void）playPause应该起作用

IBAction在theos编译时出错
