準(zhǔn)備工作：
1.https服務(wù)器。
2.在微信開放平臺(tái)創(chuàng)建應(yīng)用朴乖，申請支付功能祖屏，獲取App ID助赞。
開始對接支付功能：
第一步：安裝sdk
打開Xcode，通過Pod安裝微信SDK：
pod 'WechatOpenSDK'
pod install
第二步：項(xiàng)目配置
2.1：配置 URL Types
2.2：info.plist 添加白名單赐劣，weixin嫉拐、weixinULAPI
2.3：打開蘋果開發(fā)者網(wǎng)站（http://developer.apple.com），勾選 Associated Domains魁兼。
2.4：Xcode中婉徘，在 Capability 中添加 Associated Domains，Domains:填寫【applinks:域名】咐汞，如
第三步：配置 Universal Link(通用鏈接)
創(chuàng)建空白文本盖呼，命名為apple-app-site-association（無后綴），
內(nèi)容如：
{
"applinks": {
"apps": [],
"details": [
{
"appID": "2EX886S24H.com.ZXKJ.Maintenance",
"paths": ["/app/*"]
}
]
}
}
說明：appID填寫格式： "TeamID.Bundle ID"化撕，“蘋果賬號(hào)團(tuán)隊(duì)ID.BundleID”
文件交給后臺(tái)程序員几晤，上傳至根目錄或 .well-known 目錄下。形成鏈接后植阴，可下載即成功蟹瘾。
https://cloud.xxxxxx.com/.well-known/apple-app-site-association
?????? Universal Links 配置舉??
假設(shè)域名為：https://www.mydomain.com
1.微信開放平臺(tái)設(shè)置為：
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 填寫：
4.Xcode中代碼配置為：
[WXApi registerApp:@"App Id" universalLink:@"https://www.mydomain.com/app/"];
第四步：微信支付代碼
AppDelegate.m 中導(dǎo)入頭文件
#import "WXApi.h"
: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 中加入代碼：
//微信調(diào)試代碼
/*
[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!");
}
//調(diào)用自檢函數(shù)掠手，調(diào)試代碼
/*
[WXApi checkUniversalLinkReady:^(WXULCheckStep step, WXCheckULStepResult* result) {
NSLog(@"WeChatSDK step = %@, %u, %@, %@ result=%@", @(step), result.success, result.errorInfo, result.suggestion, result);
}];
*/
??不能少憾朴！否則無法調(diào)起微信
#pragma mark - 設(shè)置系統(tǒng)回調(diào)

微信支付工具類：

request.timeStamp = [dataDict[@"timeStamp"] intValue];
request.sign = dataDict[@"sign"];
[WXApi sendReq:request completion:^(BOOL success) {
NSLog(@"success - %d", success);

}
}
#pragma mark - Delegate回調(diào)方法
- (void)onResp:(id)resp {

default: {

if (self.payFailedBlock) {

@end
支付頁面調(diào)用工具類：
- (void)wxPay {
NSDictionary *data = @{
@"appId" : @"wx862e7a21b8df70b7",
@"nonceStr" : @"li8tjxvshpxcmryefu8b87xftdf4ljnn",

@"sign" : @"03359D5970F910EE5609E7BB4CA52DA8",
@"timeStamp": @"1631166282"
};
[WXTools doWXPay:data paySuccess:^{
NSLog(@"success！");
} payFailed:^{
NSLog(@"支付失敗");
}];
}
說明
?????? 全部配置完后喷鸽，如果微信調(diào)用不起來众雷，使用SDK 自檢函數(shù)排查問題
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，說明sdk接入和配置都沒有問題做祝。
