一、配置微信白名单
首先你在Xcode中，选择你的工程设置项，选中“TARGETS”一栏，在“info”标签栏的“LSApplicationQueriesSchemes“添加weixin

二、配置APP的URL Scheme
配置APP的URL Scheme
特别注意，能成功返回的关键在于URL Scheme的填写内容！
假设你想要App标识为abc，公司域名为baidu.com。那么URL Scheme就为：abc.baidu.com
其中，公司域名应与在微信商户平台填写的一致才能正常支付。如需添加或修改授权域名申请H5支付时提交的授权域名，请登陆商户号对应的商户平台--"产品中心"--"开发配置"自行配置！

三、APP端代码
APP端代码
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
NSString *str = request.URL.absoluteString;
if ([str hasPrefix:@"https://wx.tenpay.com"]) {
NSDictionary *headers = [request allHTTPHeaderFields];
NSString *string = [NSString stringWithFormat:@"%@",[headers objectForKey:@"Referer"]];
if ([string hasPrefix:@"http"] || [string containsString:@"null"] || string.length == 0) {
NSURL *url = [request URL];
NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:10.0];
NSArray *tmpArray = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleURLTypes"];
for (NSDictionary *tmpDic in tmpArray) {
NSString *CFBundleURLName = [NSString stringWithFormat:@"%@",tmpDic[@"CFBundleURLName"]];
if ([CFBundleURLName isEqualToString:[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleIdentifier"]]) {
NSArray *CFBundleURLSchemesArray = [NSArray arrayWithArray:tmpDic[@"CFBundleURLSchemes"]];
if (CFBundleURLSchemesArray.count > 0) {
NSString *needString = [NSString stringWithFormat:@"%@",CFBundleURLSchemesArray[0]];
[request setValue:[NSString stringWithFormat:@"%@://",needString] forHTTPHeaderField:@"Referer"];
[self.webView loadRequest:request];
}
break;
}
}
}
}
return YES;
}
这样，不仅能够正常支付，在微信支付界面也能直接跳转回APP了。
