　　1.https服务器。

　　2.在微信开放平台创建应用，申请支付功能，获取App ID。

　　打开Xcode，通过Pod安装微信SDK：

　　pod 'WechatOpenSDK'

　　pod install

　　2.1：配置 URL Types

　　

　　2.2：info.plist 添加白名单，weixin、weixinULAPI

　　

　　2.3：打开苹果开发者网站（http://developer.apple.com），勾选 Associated Domains。

　　

　　2.4：Xcode中，在 Capability 中添加 Associated Domains，Domains:填写【applinks:域名】，如

　　applinks:www.xxxx.com

　　

　　第三步：配置 Universal Link(通用链接)

　　创建空白文本，命名为apple-app-site-association（无后缀），

　　内容如：

　　

　　说明：appID填写格式： "TeamID.Bundle ID"，“苹果账号团队ID.BundleID”

　　文件交给后台程序员，上传至根目录或 .well-known 目录下。形成链接后，可下载即成功。

　　https://cloud.xxxxxx.com/.well-known/apple-app-site-association

　　Universal Links 配置举

　　假设域名为：https://www.mydomain.com

　　1.微信开放平台设置为：

　　https://www.mydomain.com/app/

　　2.apple-app-site-association 配置文件：

　　{

　　"appID": "2EX886S24H.com.ZXKJ.Maintenance",

　　"paths": ["/app/*"]

　　}

　　3.在 Xcode -> Targets -> Signing & Capability -> Associated Domains，Domains 填写：

　　applinks:www.mydomain.com

　　4.Xcode中代码配置为：

　　[WXApi registerApp:@"App Id" universalLink:@"https://www.mydomain.com/app/"];

　　AppDelegate.m 中导入头文件

　　#import "WXApi.h"

　　: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 中加入代码：

　　//微信调试代码 /* [WXApi startLogByLevel:WXLogLevelDetail logBlock:^(NSString *log) { NSLog(@"WeChatSDK: %@", log); }]; */ /* 微信 */ BOOL success = [WXApi registerApp:WeChat_AppKey universalLink:WeChat_universalLink]; if (success) { NSLog(@"微信 registerApp success!"); } //调用自检函数，调试代码 /* [WXApi checkUniversalLinkReady:^(WXULCheckStep step, WXCheckULStepResult* result) { NSLog(@"WeChatSDK step = %@, ?, %@ result=%@", @(step), result.success, result.errorInfo, result.suggestion, result); }]; */

　　不能少！否则无法调起微信

　　#pragma mark - 设置系统回调// NOTE: 9.0以后使用新API接口 - (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey, id> *)options { BOOL result_wechat = [WXTools handleOpenURL:url]; if (result_wechat) { return result_wechat; } return NO; }// Universal Link(通用链接) - (BOOL)application:(UIApplication *)application continueUserActivity:(NSUserActivity *)userActivity restorationHandler:(void (^)(NSArray<id<UIUserActivityRestoring>> * _Nullable))restorationHandler { BOOL result_wechat = [WXTools handleOpenUniversalLink:userActivity]; if (result_wechat) { return result_wechat; } return NO;}

　　微信支付工具类：

　　#import <Foundation/Foundation.h>#import "WXApi.h"#define WXTools [WXPayTools sharedInstance]#define WeChat_AppKey @""@interface WXPayTools : NSObject+ (WXPayTools *)sharedInstance;// 回调- (BOOL)handleOpenURL:(NSURL *)url;// 回调 Universal Link(通用链接)- (BOOL)handleOpenUniversalLink:(NSUserActivity *)userActivity;/** wechat支付 */- (void)doWXPay:(NSDictionary *)reqDict paySuccess:(void (^)(void))paySuccessBlock payFailed:(void (^)(void))payFailedBlock;@end

　　WXPayTool.m

　　#import "WXPayTools.h"@interface WXPayTools ()<WXApiDelegate>@property (nonatomic, copy) void (^authSuccessBlock)(NSString *reqCode);@property (nonatomic, copy) void (^paySuccessBlock)(void);@property (nonatomic, copy) void (^payFailedBlock)(void);@end@implementation WXPayTools+ (WXPayTools *)sharedInstance { static WXPayTools *instance = nil; static dispatch_once_t onceToken; dispatch_once(&onceToken, ^{ instance = [WXPayTools new]; }); return instance;}// 回调- (BOOL)handleOpenURL:(NSURL *)url { if ([[url absoluteString] rangeOfString:[NSString stringWithFormat:@"%@://pay/", WeChat_AppKey]].location == 0) { return [WXApi handleOpenURL:url delegate:self]; } return NO;}// 回调 Universal Link(通用链接)- (BOOL)handleOpenUniversalLink:(NSUserActivity *)userActivity { return [WXApi handleOpenUniversalLink:userActivity delegate:self];}/** wechat支付 */- (void)doWXPay:(NSDictionary *)dataDict paySuccess:(void (^)(void))paySuccessBlock payFailed:(void (^)(void))payFailedBlock; { self.paySuccessBlock = paySuccessBlock; self.payFailedBlock = payFailedBlock; if ([dataDict isKindOfClass:[NSDictionary class]]) { PayReq *request = [[PayReq alloc] init]; request.partnerId = dataDict[@"partnerId"]; request.prepayId = dataDict[@"prepayId"]; request.package = @"Sign=WXPay"; request.nonceStr = dataDict[@"nonceStr"]; request.timeStamp = [dataDict[@"timeStamp"] intValue]; request.sign = dataDict[@"sign"]; [WXApi sendReq:request completion:^(BOOL success) { NSLog(@"success - %d", success); }]; }}#pragma mark - Delegate回调方法- (void)onResp:(id)resp { if ([resp isKindOfClass:[PayResp class]]) { PayResp *response = (PayResp *)resp; switch(response.errCode) { case WXSuccess: { NSLog(@"支付成功"); if (self.paySuccessBlock) { self.paySuccessBlock(); } } break; default: { NSLog(@"支付失败"); if (self.payFailedBlock) { self.payFailedBlock(); } } break; } } } @end

　　支付页面调用工具类：

　　- (void)wxPay { NSDictionary *data = @{ @"appId" : @"wx862e7a21b8df70b7", @"nonceStr" : @"li8tjxvshpxcmryefu8b87xftdf4ljnn", @"partnerId": @"1611925030", @"prepayId" : @"wx0913444284359740c9002e4995965f0000", @"sign" : @"03359D5970F910EE5609E7BB4CA52DA8", @"timeStamp": @"1631166282" }; [WXTools doWXPay:data paySuccess:^{ NSLog(@"success！"); } payFailed:^{ NSLog(@"支付失败"); }];}

　　全部配置完后，如果微信调用不起来，可使用SDK 自检函数排查问题WeChatSDK step = 0, 1, check passed,WeChatSDK step = 1, 1, check passed,WeChatSDK step = 2, 1, check passed,WeChatSDK step = 3, 1, check passed,WeChatSDK step = 4, 1, check passed,WeChatSDK step = 5, 1, Universal Link check passed. The application is launched by WeChat via Universal Link,WeChatSDK step = 6, 1, All Check Passed!,

　　step 6 走完，说明sdk接入和配置都没有问题。
