我使用以下main.m文件进行此操作:

I have this working with the following main.m file:

#import <AppKit/AppKit.h>
#import <GameController/GameController.h>

@interface AppDelegate : NSObject<NSApplicationDelegate> @end

@implementation AppDelegate
- (void) applicationDidFinishLaunching: (NSNotification*) notification {
    [NSApp stop: nil]; // Allows [app run] to return
}
@end

int main() {
    NSApplication* app = [NSApplication sharedApplication];
    [app setActivationPolicy: NSApplicationActivationPolicyRegular];
    [app setDelegate: [[AppDelegate alloc] init]];
    [app run];

    // 1 with a DualShock 4 plugged in
    printf("controllers %lu\n", [[GCController controllers] count]);

    // Do stuff here

    return 0;
}

编译为: clang -framework AppKit -framework GameController main.m

我不知道为什么，但是我需要在构建输出目录中有一个Info.plist文件.没有它，controllers数组将不会被填充.这是我的整个文件:

I have no idea why, but I need an Info.plist file in the build output directory. Without it, the controllers array doesn't get populated. This is my entire file:

<dict>
    <key>CFBundleIdentifier</key>
    <string>your.bundle.id</string>
</dict>

我不确定提供Info.plist可能有什么含义，但是如果存在，我可以像往常一样运行a.out可执行文件，并得到我的控制器数组.

I'm not sure what implications supplying an Info.plist might have, but if it's there, I can run the a.out executable as normal and I get my controllers array.
