创建项目时使用的Xcode 版本是 11.3 , AppDelegate 已拆分开来 ,存在ScaneDelegate 窗口代理 , 微信SDK也更新到最新版本, 1.8.6, 如果Xcode 的版本低于11, 在AppDelegate 没有被拆分的时候创建的项目 . 使用微信登录或支付在 iOS 系统版本 13 以上都是OK 的 , 需要讲的是高版本Xcode下的微信回调,
窗口代理SceneDelegate'
- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions API_AVAILABLE(ios(13.0)){
if (scene) {
[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;
UIWindowScene *windowScene = (UIWindowScene *)scene;
self.window = [[UIWindow alloc] initWithWindowScene:windowScene];
self.window.frame = CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height);
[NSThread sleepForTimeInterval:1.5];
// 已废弃, 使用 [WXApi registerApp:APP_ID universalLink:Universal_Links];
// [WXApi registerApp:APP_ID];
// Universal_Links 是通用配置, 微信SDK 有详细说明,
[WXApi registerApp:APP_ID universalLink:Universal_Links];
// 其他界面操作
LoginViewController *loginVC = [[LoginViewController alloc]initWithNibName:@"LoginViewController" bundle:nil];
self.window.rootViewController = loginVC;
self.window.overrideUserInterfaceStyle = UIUserInterfaceStyleLight;
[self.window makeKeyAndVisible];
}
}
在调试过程中. 发现 iOS 版本在 13 至13.2 时回调的方法如下:
#pragma mark ===== 适配 iOS 13 - 13.2
-(void)scene:(UIScene *)scene openURLContexts:(NSSet *)URLContexts
{
NSEnumerator *enumerator = [URLContexts objectEnumerator];
UIOpenURLContext *context;
while (context = [enumerator nextObject]) {
NSString *url = [NSString stringWithFormat:@"%@",context.URL];
// getURLParameters 是 自定义的一个字符串转字典的方法,
NSDictionary *urlDic = [self getURLParameters:url];
if([url containsString:@"oauth"]){
if (urlDic.allKeys > 0) {
// 微信登录时的状态标识
if ([urlDic[@"state"] isEqualToString:@"YYLxxxx"]) {
NSString *requestStr = [NSString stringWithFormat:@"code=%@&type=1",urlDic[@"code"]];
// 自己封装的方法向后台请求微信登录
[self wechatLoginWithUrlStr:requestStr];
// 微信回调的状态等于 AuthorizeApp 授权认证时
}else if ([urlDic[@"state"] isEqualToString:@"AuthorizeApp"]){
NSDictionary *dic = @{@"code":urlDic[@"code"]};
NOTIFICATION_POST_USERINFO(WXCHATAUTHORIZE_KEY, nil, dic);
}
}
// 微信支付的回调
}else if([url containsString:@"pay"]){
switch([urlDic[@"ret"] intValue]){
case 0:
{
NSLog(@"支付成功");
NOTIFICATION_POST(PAYSUCCESS_KEY);
}
break;
case -2:
{
NSLog(@"用户点击取消");
NOTIFICATION_POST(PAYCANCEL_KAY);
}
break;
default: NOTIFICATION_POST(PAYFAILE_KEY);
NSLog(@"支付失败，retcode = %@",urlDic[@"ret"]);
break;
}
// 重点: 判断APPID 是否一致 , 调用微信Api处理.
}else if ([context.URL.scheme rangeOfString:@"wx56102e6e4cxxxxxxx"].length!=0) {
// 完整的 URL样式应为: wx56102e4c3rr6hfd://resendContextReqByScheme?wechat_auth_context_id=9xxxxxx6228692e3957321bc9xxxxxxxxxxxx
[WXApi handleOpenURL:context.URL delegate:self];
}
// 打印出相关的数据
NSLog(@"urlDic ==== %@",urlDic);
NSLog(@"context.URL =====%@",context.URL);
NSLog(@"context.options.sourceApplication ===== %@",context.options.sourceApplication);
}
}
以上在我测试时. 系统版本 13 至 13.2 回调正常, 在 iOS 13.3 系统版本上依然没有回调 , 在写项目时 , 13.3 刚出来一个星期, 以为万事大吉, 万万没想到..hhhhhh
13.3 的回调方法:
#pragma mark ====== 适配 iOS 13.3
- (void)scene:(UIScene *)scene continueUserActivity:(NSUserActivity *)userActivity
{
if (userActivity.webpageURL) {
NSLog(@" %@",userActivity.webpageURL);
BOOL isSuccess = [WXApi handleOpenUniversalLink:userActivity delegate:self];
NSLog(@"ios 13 %@",@(isSuccess));
}
}
到此就全部ok了 , 至于
-(void)onResp:(BaseResp *)resp
这个方法, 我也有写上, 和旧版写在 Appdelegate 一致, 但在测试过程中, 好像并没有走这个方法,
附上字符串 转字典的封装方法:
-(NSMutableDictionary*)getURLParameters:(NSString *)urlStr {
NSRange range = [urlStr rangeOfString:@"?"];
if(range.location==NSNotFound) {
return nil;
}
NSMutableDictionary *params = [NSMutableDictionary dictionary];
NSString *parametersString = [urlStr substringFromIndex:range.location+1];
if([parametersString containsString:@"&"]) {
NSArray *urlComponents = [parametersString componentsSeparatedByString:@"&"];
for(NSString *keyValuePair in urlComponents) {
//生成key/value
NSArray *pairComponents = [keyValuePair componentsSeparatedByString:@"="];
NSString *key = [pairComponents.firstObject stringByRemovingPercentEncoding];
NSString*value = [pairComponents.lastObject stringByRemovingPercentEncoding];
//key不能为nil
if(key==nil|| value ==nil) {
continue;
}
id existValue = [params valueForKey:key];
if(existValue !=nil) {
//已存在的值，生成数组。
if([existValue isKindOfClass:[NSArray class]]) {
//已存在的值生成数组
NSMutableArray*items = [NSMutableArray arrayWithArray:existValue];
[items addObject:value];
[params setValue:items forKey:key];
}else{
//非数组
[params setValue:@[existValue,value]forKey:key];
}
}else{
//设置值
[params setValue:value forKey:key];
}
}
}else{
//单个参数生成key/value
NSArray *pairComponents = [parametersString componentsSeparatedByString:@"="];
if(pairComponents.count==1) {
return nil;
}
//分隔值
NSString *key = [pairComponents.firstObject stringByRemovingPercentEncoding];
NSString *value = [pairComponents.lastObject stringByRemovingPercentEncoding];
//key不能为nil
if(key ==nil|| value ==nil) {
return nil;
}
//设置值
[params setValue:value forKey:key];
}
return params;
}
