Class gcClass = (NSClassFromString(@"GKLocalPlayer"));
// The device must be running running iOS 4.1 or later.
NSString *reqSysVer = @"4.1";
NSString *currSysVer = systemVersion];
BOOL osVersionSupported = ( != NSOrderedAscending);
if (gcClass && osVersionSupported) {
NSLog(@"支持GKLocalPlayer");
} else {
NSLog(@"不支持GKLocalPlayer");
}
我用上面的代码，100%跑到else里。cocos studio创建的工程。文件也是.mm后缀的。为什么没法写game center的代码呢？
哪位大神晓得，帮帮忙吧。
