unity接入支付寶支付(ios)

遇到專案需要接入微信和支付寶支付，安卓平臺弄完了，結果在ios平臺卡了很久，這里記錄下主要遇到的問題，

unity版本：2019.4.27

xcode版本：12.4

對于xcode中的配置，我使用代碼的方式自動配置了，以下代碼就是設定xcode的，這個代碼借鑒了這里的，

using UnityEditor;
using System.IO;
using UnityEngine;

#if UNITY_IOS && UNITY_EDITOR
using UnityEditor.Callbacks;
using UnityEditor.iOS.Xcode;
#endif

public static class XCodePostProcessBuild
{
#if UNITY_IOS && UNITY_EDITOR
    private static readonly string[] csAddFrameworks = new string[]{
        "Security.framework","WebKit.framework", "CoreGraphics.framework", "CoreTelephony.framework", "libz.tbd" ,"libsqlite3.0.tbd", "libc++.tbd"
        , "SystemConfiguration.framework", "QuartzCore.framework", "CoreText.framework", "UIKit.framework", "Foundation.framework", "CFNetwork.framework"
        , "CoreMotion.framework", "AlipaySDK.framework"
    };

    [PostProcessBuild(1)]
    public static void OnPostprocessBuild(BuildTarget buildTarget, string pathToBuiltProject)
    {
        if (BuildTarget.iOS != buildTarget)
        {
            return;
        }
        string projectPath = pathToBuiltProject + "/Unity-iPhone.xcodeproj/project.pbxproj";
        SetFrameworksAndBuildSettings(projectPath);
        SetInfoList(pathToBuiltProject, "填自己微信工程的bundle id", "自己微信工程的appid");
        
        SetAssociatedDomains(projectPath, "pay.91mayou.com/myddz/");
    }

    private static void SetFrameworksAndBuildSettings(string path)
    {
        PBXProject proj = new PBXProject();
        proj.ReadFromString(File.ReadAllText(path));
        string target = proj.GetUnityMainTargetGuid();
        Debug.Log("Target Name is " + target);
        // 設定 BuildSettings
        proj.AddBuildProperty(target, "Other Linker Flags", "-Objc -all_load");
        proj.SetBuildProperty(target, "ENABLE_BITCODE", "NO");

        //根據微信SDK檔案的要求，加入相關的Frameworks
        for (int i = 0; i < csAddFrameworks.Length; ++i)
        {
            if (!proj.ContainsFramework(target, csAddFrameworks[i]))
                proj.AddFrameworkToProject(target, csAddFrameworks[i], false);
        }

        File.WriteAllText(path, proj.WriteToString());
    }

    public static void SetInfoList(string buildPath, string wxUrlName, string wxScheme)
    {
        string listPath = buildPath + "/Info.plist";
        PlistDocument plist = new PlistDocument();
        plist.ReadFromString(File.ReadAllText(listPath));

        
   
        // 在“info”標簽欄的“URL type“添加“URL scheme”,值為你在微信后臺注冊的應用程式的 AppID
        PlistElementArray urlArray = plist.root.CreateArray("CFBundleURLTypes");
        PlistElementDict dict = urlArray.AddDict();
        dict.SetString("CFBundleTypeRole", "Editor");
        dict.SetString("CFBundleURLName", wxUrlName);
        PlistElementArray urlSchemes = dict.CreateArray("CFBundleURLSchemes");
        urlSchemes.AddString(wxScheme);

        // 在“info”標簽欄的“URL type“添加“URL scheme”,原本只有微信，支付寶這里新增的
        PlistElementArray urlArray2 = plist.root.values["CFBundleURLTypes"].AsArray();
        PlistElementDict dict2 = urlArray2.AddDict();
        dict2.SetString("CFBundleTypeRole", "Editor");
        dict2.SetString("CFBundleURLName", "支付寶平臺的appid");
        PlistElementArray urlSchemes2 = dict2.CreateArray("CFBundleURLSchemes");
        urlSchemes2.AddString("填自己的專案標識哪個字串 官方例子是：alisdkdemo");
        

        // 在 “info”標簽欄的“LSApplicationQueriesSchemes“添加weixin wechat和weixinULAPI
        PlistElementArray wxArray = plist.root.CreateArray("LSApplicationQueriesSchemes");
        wxArray.AddString("weixin");
        wxArray.AddString("wechat");
        wxArray.AddString("weixinULAPI");
        wxArray.AddString("alipay");
        
        File.WriteAllText(listPath, plist.WriteToString());
    }

    // 設定Associated Domains
    public static void SetAssociatedDomains(string pbxProjectPath, string domainUrl)
    {
        //默認 Target Name, 你自己的可能不一樣
        string targetName = "Unity-iPhone";
        //Set the entitlements file name to what you want but make sure it has this extension
        string entitlementsFileName = "my_app.entitlements";

        var entitlements = new ProjectCapabilityManager(pbxProjectPath, entitlementsFileName, targetName);
        entitlements.AddAssociatedDomains(new string[] { "applinks:" + domainUrl });

        entitlements.WriteToFile();
    }

#endif
}

上面腳本設定xcode是沒有設定開發團隊的，需要自己手動選擇.

關于支付寶的接入，主要借鑒了這里，但是我沒有添加那么多檔案到plugins檔案夾下，支付寶我只添加了這兩個，

AlipaySDK.bundle
AlipaySDK.framework

至于那個pay_oc.m腳本如下：

#import <Foundation/Foundation.h>
//#import "APOrderInfo.h"
//#import "APRSASigner.h"
#import <AlipaySDK/AlipaySDK.h>
 
@implementation APViewController
 
 
@end
 
#if defined (__cplusplus)
extern "C"
{
#endif
#pragma mark   ==============點擊支付行為==============
    void iospay(const char *orderString )
    {
		NSLog(@"呼叫到支付寶的支付了");
        //應用注冊scheme,在Info.plist定義URL types
        NSString *appScheme = @"ali_myddz";
        NSString *orderStr = [NSString stringWithUTF8String:orderString];
        if (orderString != nil) {
            
            [[AlipaySDK defaultService] payOrder:orderStr fromScheme:appScheme callback:^(NSDictionary *resultDic) {
                NSLog(@"reslut = %@",resultDic);
				if([resultDic[@"resultStatus"]  isEqual: @"9000"])
				{
					UnitySendMessage("WeChatComponent", "AliPayCallback", "true");
				}
				else
				{
					UnitySendMessage("WeChatComponent", "AliPayCallback", "false");
				}
            }];
        }
    }


    
#if defined (__cplusplus)
}
#endif
 

支付寶按照網上的檔案接入，一直報錯提示

按網上的說法就是庫沒填加進去，"libz.tbd" ,"libsqlite3.0.tbd", "libc++.tbd"，其實三個在下圖這兩個地方都要添加的，我開始就在1那個位置添加了，但始終報這個錯，查了兩天原因，最后發現在2位置沒有這3個，也要添加這3個庫，

而自動設定xcode配置的腳本并沒有設定成功AlipaySDK.framework這個庫，這個庫需要手動重新設定下，

到這里就可以xcode編譯通過了，但是安裝到手機測驗的時候，xcode提示 unable to install "xxx"不能裝，原因是下面圖中的需要修改成Do Not Embed（不嵌入），在上一步手動添加AlipaySDK.framework后，xcode默認是Embed & Sign（嵌入并簽名），這樣改了之后就可以真機安裝測驗了，
