iOS-Unity2019.4.24f1c1使用Jenkins自动化构建

iOS-Unity2018.4.24f1使用Jenkins自动化构建

Unity2019开始逐步将作为iOS framework形式接入工程，相比之前版本极大的方便了工程的维护。

本文脚本是从Unity生成xcode工程之后开始执行，不一定完全适用，请按照自己需求进行修改。

注意修改脚本中“xxxxxx”的地方。

一.安装xcodeproj

#安装ruby xcodeproj库
$gem install xcodeproj
#如果提示没有权限运行下面这条命令：
$sudo gem install xcodeproj

二、配置xcodeproj工程

1、Unity调用native的协议类
NativeCallProxy.h

// [!] important set UnityFramework in Target Membership for this file
// [!]           and set Public header visibility

#import 

// NativeCallsProtocol defines protocol with methods you want to be called from managed
@protocol NativeCallsProtocol

@required
- (void)ShowNativeWindow;
- (void)NativeSupportService:(NSString *)json;
@end

__attribute__ ((visibility("default")))
@interface UnityFrameworkLibAPI : NSObject

// call it any time after UnityFrameworkLoad to set object implementing NativeCallsProtocol methods
+ (void)RegisterAPIforNativeCalls:(id)aApi;

// 原生发送消息给Unity
+ (void)SendMessageToUnity:(NSString *)obj method:(NSString *)method msg:(NSString *)msg;

+ (void)OutOfAshes;

@end

NativeCallProxy.mm

#include "NativeCallProxy.h"
#include "UnityInterface.h"
#include "UnityAppController.h"
#include "UnityAppController+OutOfAshes.h"

@implementation UnityFrameworkLibAPI

id api = NULL;

+ (void)load {
    extern const char* AppControllerClassName;
    AppControllerClassName = "AppDelegate";
}

+ (void)RegisterAPIforNativeCalls:(id)aApi {
    api = aApi;
}

+ (void)SendMessageToUnity:(NSString *)obj method:(NSString *)method msg:(NSString *)msg {
    UnitySendMessage([obj UTF8String], [method UTF8String], [msg UTF8String]);
}

+ (void)OutOfAshes {
    [GetAppController() outOfAshes];
}

@end

extern "C" void ShowNativeWindow()
{
     return [api ShowNativeWindow];
}

/// Core Methods
extern "C" void NativeSupportService(const char *JSON)
{
    return [api NativeSupportService:[NSString stringWithUTF8String:JSON]];
}

/// Displays unity views after the startup diagram ends
extern "C" void UnityOutOfAshes()
{
    [GetAppController() outOfAshes];
}

2、控制启动图消失分类
UnityAppController+OutOfAshes.h

//
//  UnityAppController+OutOfAshes.h
//  xxxxxx
//
//  Created by xxxxxx on 2021/5/12.
//

#include "UnityAppController.h"

NS_ASSUME_NONNULL_BEGIN

@interface UnityAppController (OutOfAshes)

- (void)outOfAshes;

@end

NS_ASSUME_NONNULL_END

UnityAppController+OutOfAshes.mm

//
//  UnityAppController+OutOfAshes.m
//  xxxxxx
//
//  Created by xxxxxx on 2021/5/12.
//

#include "UnityAppController+OutOfAshes.h"
#include "UnityAppController+Rendering.h"

#include "UI/OrientationSupport.h"
#include "UI/UnityView.h"
#include "UI/UnityViewControllerBase.h"
#include "UI/ActivityIndicator.h"

extern bool _skipPresent;
extern bool _unityAppReady;


@interface UnityAppController ()

- (void)transitionToViewController:(UIViewController*)vc;

- (void)updateAppOrientation:(UIInterfaceOrientation)orientation;

- (UIViewController*)createUnityViewControllerDefault;

- (void)orientInterface:(UIInterfaceOrientation)orient;

@end

@implementation UnityAppController (OutOfAshes)

- (void)outOfAshes
{
    if (_rootController != _viewControllerForOrientation[0])
        [self transitionToViewController: _viewControllerForOrientation[0]];
}

- (void)checkOrientationRequest
{
    if (!UnityHasOrientationRequest() && !UnityShouldChangeAllowedOrientations())
        return;

    // normally we want to call attemptRotationToDeviceOrientation to tell iOS that we changed orientation constraints
    // but if the current orientation is disabled we need special processing, as iOS will simply ignore us
    //   the only good/robust way is to simply recreate "autorotating" view controller and transition to it if needed

    // please note that we want to trigger "orientation request" code path if we recreate autorotating view controller
    bool changeOrient = UnityHasOrientationRequest();

    // first we check if we need to update orientations enabled for autorotation
    // this needs to be done *only* if we are to continue autorotating
    //   otherwise we will transition from this view controller
    //   and iOS will reread enabled orientations on next ViewController activation
    const bool autorot = UnityShouldAutorotate();
    if (UnityShouldChangeAllowedOrientations() && autorot)
    {
        NSUInteger rootOrient = 1 << UIViewControllerInterfaceOrientation(self.rootViewController);
        if (_rootController == _viewControllerForOrientation[0] && (rootOrient & EnabledAutorotationInterfaceOrientations()))
        {
            // if we are currently autorotating AND changed allowed orientations while keeping current interface orientation allowed:
            // we can simply trigger attemptRotationToDeviceOrientation and we are done
            // please note that this can happen when current *device* orientation is disabled (and we want to enable it)
            [UIViewController attemptRotationToDeviceOrientation];
        }
        else
        {
            // otherwise we recreate default autorotating view controller
            // please note that below we will check if root controller still equals _viewControllerForOrientation[0]
            // in that case (we update _viewControllerForOrientation[0]) the check will fail and will trigger transition (as expected)
            // you may look at this check as "are we autorotating with same constraints"
            _viewControllerForOrientation[0] = [self createUnityViewControllerDefault];
            changeOrient = true;
        }
    }

    if (changeOrient)
    {
        // on some devices like iPhone XS layoutSubview is not called when transitioning from different orientations with the same resolution
        // therefore forcing layoutSubview on all orientation changes
        [_unityView setNeedsLayout];

        if (autorot)
        {
            if (_viewControllerForOrientation[0] == nil)
                _viewControllerForOrientation[0] = [self createUnityViewControllerDefault];
//            if (_rootController != _viewControllerForOrientation[0])
//                [self transitionToViewController: _viewControllerForOrientation[0]];
            [UIViewController attemptRotationToDeviceOrientation];
        }
        else
        {
            UIInterfaceOrientation requestedOrient = ConvertToIosScreenOrientation((ScreenOrientation)UnityRequestedScreenOrientation());
            // on one hand orientInterface: should be perfectly fine "reorienting" to current orientation
            // in reality, ios might be confused by transitionToViewController: shenanigans coupled with "nothing have changed actually"
            // as an example: prior to ios12 that might result in status bar going "bad" (becoming transparent)
            if (_rootController != _viewControllerForOrientation[requestedOrient])
                [self orientInterface: requestedOrient];
        }
    }

    UnityOrientationRequestWasCommitted();
}

- (void)showGameUI
{
    HideActivityIndicator();
//    HideSplashScreen();

    // make sure that we start up with correctly created/inited rendering surface
    // NB: recreateRenderingSurface won't go into rendering because _unityAppReady is false
#if UNITY_SUPPORT_ROTATION
    [self checkOrientationRequest];
#endif
    [_unityView recreateRenderingSurface];

    // UI hierarchy
    //[_window addSubview: _rootView];
    //_window.rootViewController = _rootController;
    //[_window bringSubviewToFront: _rootView];

#if UNITY_SUPPORT_ROTATION
    // to be able to query orientation from view controller we should actually show it.
    // at this point we finally started to show game view controller. Just in case update orientation again
    [self updateAppOrientation: ConvertToIosScreenOrientation(UIViewControllerOrientation(_rootController))];
#endif

    // why we set level ready only now:
    // surface recreate will try to repaint if this var is set (poking unity to do it)
    // but this frame now is actually the first one we want to process/draw
    // so all the recreateSurface before now (triggered by reorientation) should simply change extents

    _unityAppReady = true;

    // why we skip present:
    // this will be the first frame to draw, so Start methods will be called
    // and we want to properly handle resolution request in Start (which might trigger surface recreate)
    // NB: we want to draw right after showing window, to avoid black frame creeping in

    _skipPresent = true;

    if (!UnityIsPaused())
        UnityRepaint();

    _skipPresent = false;
    [self repaint];

    [UIView setAnimationsEnabled: YES];
}

@end

NativeCallProxy类主要是提供Unity和native交互功能，UnityAppController+OutOfAshes类控制启动图移除，满足去除app启动图到显示UnityUI中间白屏的需求。

这两类作为实体文件放入Unity工程的iOS插件使用。

3、配置Xcode工程脚本

#执行脚本示例：
$ruby '配置脚本文件路径' 'Unity生成的xcode工程根目录'

require "fileutils"
require 'xcodeproj'

        unityFramework_header_target_place = "#import \"UnityAppController.h\""
        unityFramework_header_target_replace = "#import \"UnityAppController.h\"\n#import \"NativeCallProxy.h\""

        File.open("./UnityFramework/UnityFramework.h","r:utf-8") do |lines|
            read = lines.read.clone
            if read.include?(unityFramework_header_target_replace)
                puts "\nUnityFramework.h已包含“#import \"NativeCallProxy.h\"”"
                return false
            else
                buffer = read.gsub(unityFramework_header_target_place,unityFramework_header_target_replace)
                File.open("./UnityFramework/UnityFramework.h","w"){|l|

                return true
            end
        end
    end    

    #修改UNITY_TRAMPOLINE_IN_USE配置
    def change_unity_use_remote_notifications_flag()
        unity_use_remote_notifications_flag_close = "#define UNITY_USES_REMOTE_NOTIFICATIONS 0"
        unity_use_remote_notifications_flag_open = "#define UNITY_USES_REMOTE_NOTIFICATIONS 1"

三、编译Xcode工程、导出ipa、发布ipa包到fir和AppStore

参考上一篇：iOS-Unity2018.4.24f1使用Jenkins自动化构建

四、工程目录示例图

主工程AppDelegate.h代码.png

五、配置工程中出现的一些错误

[libil2cpp] ERROR: Could not open /var/containers/Bundle/Application/xxxxxx/xxxxxx.app/Frameworks/UnityFramework.framework/Data/Managed/Metadata/global-metadata.dat IL2CPP initialization failed
网上有其他解决方法，我集成时出现此错误是因为没有给主工程main.mm添加[ufw setDataBundleId: "com.unity3d.framework"];
