准备工作：
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。
开始对接支付功能：
第一步：安装sdk
打开Xcode，通过Pod安装微信SDK：
pod 'WechatOpenSDK'
pod install
第二步：项目配置
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
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：
{
"applinks": {
"apps": [],
"details": [
{
"appID": "2EX886S24H.com.ZXKJ.Maintenance",
"paths": ["/app/*"]
}
]
}
}
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：
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：
4.Xcode中代码配置为：
[WXApi registerApp:@"App Id" universalLink:@"https://www.mydomain.com/app/"];
第四步：微信支付代码
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 = %@, %u, %@, %@ result=%@", @(step), result.success, result.errorInfo, result.suggestion, result);
}];
*/

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");
}];
}
说明
⚠️⚠️⚠️ 全部配置完后，如果微信调用不起来，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。
