最近苹果要求苹果的app们都要支持64位系统。所以Untiy也在忙着做64位的适配。为了不影响Unity 的开发者的产品上线计划,Unity 在2015年1月14日发布了第一个支持64位iOS的 Unity4.6公测版本。于是我就下了个Unity4.6.1f1,发现它根本不支持arm64。没错人家说的是“发布了第一个支持64位iOS的 Unity4.6公测版本”,而不是正式版,公测版本的命名大概是Unity4.6.1px这样的不是Unity4.6.1fx。所以……
顺便说一下升级Unity4.6.1f1后对原来Xcode工程的影响。
由于在之前用Unity4.5的时候,我们要接入许多第三方SDK,所以我们对UnityAppController.mm做了很多修改。升级到4.6.1f1后Build Xcode工程时如果直接Append会报错,大概是“IOS81……”“IOS82……”这样的错。
我们需要对UnityAppController.mm做如下修改:
1.将UnityInitTrampoline函数修改为:
void UnityInitTrampoline() { #if ENABLE_CRASH_REPORT_SUBMISSION SubmitCrashReportsAsync(); #endif InitCrashHandling(); _ios42orNewer = [[[UIDevice currentDevice] systemVersion] compare: @"4.2" options: NSNumericSearch] != NSOrderedAscending; _ios43orNewer = [[[UIDevice currentDevice] systemVersion] compare: @"4.3" options: NSNumericSearch] != NSOrderedAscending; _ios50orNewer = [[[UIDevice currentDevice] systemVersion] compare: @"5.0" options: NSNumericSearch] != NSOrderedAscending; _ios60orNewer = [[[UIDevice currentDevice] systemVersion] compare: @"6.0" options: NSNumericSearch] != NSOrderedAscending; _ios70orNewer = [[[UIDevice currentDevice] systemVersion] compare: @"7.0" options: NSNumericSearch] != NSOrderedAscending; _ios80orNewer = [[[UIDevice currentDevice] systemVersion] compare: @"8.0" options: NSNumericSearch] != NSOrderedAscending; _ios81orNewer = [[[UIDevice currentDevice] systemVersion] compare: @"8.1" options: NSNumericSearch] != NSOrderedAscending; _ios82orNewer = [[[UIDevice currentDevice] systemVersion] compare: @"8.2" options: NSNumericSearch] != NSOrderedAscending; // Try writing to console and if it fails switch to NSLog logging fprintf(stdout, "\n"); if (ftell(stdout) < 0) SetLogEntryHandler(LogToNSLogHandler); // Fix home directory environment variable. const char *newHomeDirectory = ([[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] UTF8String]); setenv("XDG_CONFIG_HOME", newHomeDirectory, 1); UnityInitJoysticks(); }
2.添加以下函数和变量
bool _ios81orNewer = false; bool _ios82orNewer = false; extern "C" const char* const* UnityFontDirs() { static const char* const dirs[] = { "/System/Library/Fonts/Cache", // before iOS 8.2 "/System/Library/Fonts/AppFonts", // iOS 8.2 "/System/Library/Fonts/Core", // iOS 8.2 "/System/Library/Fonts/Extra", // iOS 8.2 NULL }; return dirs; } void AppController_SendMainViewControllerNotification(NSString* name) { [[NSNotificationCenter defaultCenter] postNotificationName:name object:UnityGetGLViewController()]; }
如果还是不行,就不要append了,直接build一个新的Xcode工程。
