由於公司需求,需求把在IOS項目裡添加unity工程，所以在網上搜索了材料和結合自己遇到的問題，做出的總結。

先刪除項目裡的Main.storyboard 文件（聽說是為了方便切換Window）先在自己項目裡創立一個文件夾,用來寄存unity文件，然後把unity項目裡的Classes,Libraries,MapFileParser.sh拖入到項目(選中Copy items if needed,選中Create groups)將Data拖入到項目(選中Copy items if needed,選中Create folder references)，如下圖這樣: 添加所需的framework： other C Flags -> -DINIT_SCRIPTING_BACKEND=1 將Unity/Classes/Prefix.pch的代碼復制到項目裡的pch文件(留意pch裡有用到impot的都要用

#ifdef __OBJC__

#endif

給括起來,這是由於unity裡的項目有很多cpp文件,等下會發作混編錯誤)
將Classes/main.mm全部內容復制到main.m 並把擴展名改為.mm, 然後刪除Classes/main.mm文件,修正如下代碼
修正UnityAppController.h如下代碼

inline UnityAppController*	GetAppController()
{
    return (UnityAppController*)[[UIApplication sharedApplication] valueForKeyPath:@"delegate.unityController"];
}

在AppDelegate.h .m中添加如下代碼

#import <UIKit/UIKit.h>
#import "UnityAppController.h"
@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *Window;
@property (strong, nonatomic) UIWindow *unityWindow;
@property (strong, nonatomic) UnityAppController *unityController;
- (void)showUnityWindow;
- (void)hideUnityWindow;

#import "AppDelegate.h"
#import "ViewController.h"
@interface AppDelegate ()

@end

@implementation AppDelegate

- (UIWindow *)unityWindow{
    return UnityGetMainWindow();
}

- (void)showUnityWindow{
    [self.unityWindow makeKeyAndVisible];
}

- (void)hideUnityWindow{
    [self.window makeKeyAndVisible];
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
    self.window.backgroundColor = [UIColor whiteColor];
    ViewController * vc = [[ViewController alloc]init];
    self.window.rootViewController = vc;
    
    self.unityController = [[UnityAppController alloc]init];
    [self.unityController application:application didFinishLaunchingWithOptions:launchOptions];
    
    [self.window makeKeyAndVisible];
    return YES;
}


- (void)applicationWillResignActive:(UIApplication *)application {
    [self.unityController applicationWillResignActive:application];
}


- (void)applicationDidEnterBackground:(UIApplication *)application {
    [self.unityController applicationDidEnterBackground:application];
}


- (void)applicationWillEnterForeground:(UIApplication *)application {
    [self.unityController applicationWillEnterForeground:application];
}


- (void)applicationDidBecomeActive:(UIApplication *)application {
    [self.unityController applicationDidBecomeActive:application];
}


- (void)applicationWillTerminate:(UIApplication *)application {
    [self.unityController applicationWillTerminate:application];
}


@end

把UnityAppController裡的

UnityViewControllerBase* _viewControllerForOrientation[5];

改為

UIViewController* _viewControllerForOrientation[5];

先在viewcontroller裡切換到unity

#import "ViewController.h"
#import "AppDelegate.h"
@interface ViewController ()
@property(strong, nonatomic) UIButton *Btn;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    
    _Btn = [[UIButton alloc]initWithFrame:CGRectMake(40, 200, 80, 70)];
    _Btn.backgroundColor = [UIColor cyanColor];
    [_Btn setTitle:@"開啟" forState:UIControlStateNormal];
    [_Btn addTarget:self action:@selector(go) forControlEvents:UIControlEventTouchDown];
    [self.view addSubview:_Btn];
    // Do any additional setup after loading the view, typically from a nib.
}

-(void)go{
    
    //進入unity界面
    [(AppDelegate *)[UIApplication sharedApplication].delegate showUnityWindow];
    UnityPause(false);
}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end
