三方平台SDK初始化
首先导入头文件
//腾讯SDK头文件
#import <TencentOpenAPI/TencentOAuth.h>
#import <TencentOpenAPI/QQApiInterface.h>
//微信SDK头文件
#import "WXApi.h"
//新浪微博SDK头文件
#import "WeiboSDK.h"
各个平台的APPID，提前在开放平台申请好，这里直接使用。iOS平台QQ和微博支持网页可SSO授权，微信仅支持SSO授权。这里出现的类似SINAWEIBO_APPID的一些宏，新建了一个GMThirdPartyDefine.h，将这些宏、以及枚举集中放到这个文件里。
枚举文件具体内容如下：

我们可以在application: willFinishLaunchingWithOptions:中做SDK的初始化工作，这里耗时很短，放在这里是可以的。对启动时间影响可以忽略不计。
- (void)setupThirdPartySDK{
//微博SDK初始化
[WeiboSDK enableDebugMode:YES];
[WeiboSDK registerApp:SINAWEIBO_APPID];
//腾讯SDK初始化，这里delegate是 [GMThirdPartyOauthManager shareInstance]
[GMThirdPartyOauthManager shareInstance]
[GMThirdPartyOauthManager shareInstance].tencentOAuth = [[TencentOAuth alloc] initWithAppId:QQ_APPID andDelegate:[GMThirdPartyOauthManager shareInstance]];
//微信SDK初始化
[WXApi registerApp:WEIXIN_APPID enableMTA:YES];
//向微信注册支持的文件类型
UInt64 typeFlag = MMAPP_SUPPORT_TEXT | MMAPP_SUPPORT_PICTURE | MMAPP_SUPPORT_LOCATION | MMAPP_SUPPORT_VIDEO |MMAPP_SUPPORT_AUDIO | MMAPP_SUPPORT_WEBPAGE | MMAPP_SUPPORT_DOC | MMAPP_SUPPORT_DOCX | MMAPP_SUPPORT_PPT | MMAPP_SUPPORT_PPTX | MMAPP_SUPPORT_XLS | MMAPP_SUPPORT_XLSX | MMAPP_SUPPORT_PDF;
[WXApi registerAppSupportContentFlag:typeFlag];
}
GMThirdPartyOauthManager这个是用来处理授权的一个单例对象。在SSO授权的时候会调到对应的第三方APP，授权成功/失败，返回应用时候会执行下面的方法，iOS8和iOS8以上版本略有区别。在AppDelegate中需要实现以下方法。
// iOS 8 会走这个
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{
return [self commmonHandleOpenURL:url sourceApplication:sourceApplication];
}
// iOS 9、10、11 会走这个
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options{
return [self commmonHandleOpenURL:url sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey]];
}
- (BOOL)commmonHandleOpenURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication {
if ([string hasPrefix:[NSString stringWithFormat:@"wb%@",SINAWEIBO_APPID]]) {
//微博delegate同样也是[GMThirdPartyOauthManager shareInstance]
return [WeiboSDK handleOpenURL:url delegate:[GMThirdPartyOauthManager shareInstance]];
} else if([string hasPrefix:[NSString stringWithFormat:@"tencent%@",QQ_APPID]]) {
return [TencentOAuth HandleOpenURL:url];
} else if([string hasPrefix:[NSString stringWithFormat:@"QQ%@",QQ_HEX_APPID]]){
//QQ_HEX_APPID是16进制的QQ appid
NSDictionary* params = [string urlQueryToDictionary];
NSInteger error = [params[@"error"] integerValue];
if (error == 0) {
[[NSNotificationCenter defaultCenter] postNotificationName:kQQShare object:nil userInfo:@{@"state": @(GMShareResponseStateSuccess)}];
} else if (error == -4){
[[NSNotificationCenter defaultCenter] postNotificationName:kQQShare object:nil userInfo:@{@"state": @(GMShareResponseStateCancel)}];
} else {
[[NSNotificationCenter defaultCenter] postNotificationName:kQQShare object:nil userInfo:@{@"state": @(GMShareResponseStateFail)}];
}
return [TencentOAuth HandleOpenURL:url];
}else{
//微新的delegate同样也是[GMThirdPartyOauthManager shareInstance]
return [WXApi handleOpenURL:url delegate:[GMThirdPartyOauthManager shareInstance]];
}
return YES;
}
这里腾讯写了两个分支是为了兼容旧版本的手机QQ，需要增加 URL Scheme，QQ + 十六进制新AppId，不足八位在首部补0。（如 appid=222222 则 scheme=QQ0003640E）。我们可以看到我这里将三个平台的SDK的delegate统一设置成了[GMThirdPartyOauthManager shareInstance]，目的是避免代码散落各处，便于统一处理管理授权、分享的回调。
接下来就是真正的调用登陆授权

onUserSync:(GMThirdPartyUserHandler)userHandler{
[GMThirdPartyOauthManager shareInstance].user.platformType = platform;
if (platform == GMSharePlatformQQ) {

kOPEN_PERMISSION_GET_USER_INFO,
kOPEN_PERMISSION_GET_SIMPLE_USER_INFO,
nil];
[[GMThirdPartyOauthManager shareInstance].tencentOAuth setAuthShareType: AuthShareType_QQ];
[[GMThirdPartyOauthManager shareInstance].tencentOAuth authorize:permissions inSafari:NO];
__block id observer = [[NSNotificationCenter defaultCenter] addObserverForName:kQQLogin object:nil queue: [NSOperationQueue mainQueue] usingBlock:^(NSNotification * _Nonnull note) {
GMShareResponseState state = (GMShareResponseState )[note.userInfo[@"state"] integerValue];
userHandler(state, note.object);
[[NSNotificationCenter defaultCenter] removeObserver:observer];
}];
} else if (platform == GMSharePlatformWechat) {
if ([WXApi isWXAppInstalled]){
[GMThirdPartyLoginHelper wechatLogin];
__block id observer = [[NSNotificationCenter defaultCenter] addObserverForName:kWechatLogin object:nil queue: [NSOperationQueue mainQueue] usingBlock:^(NSNotification * _Nonnull note) {

request.redirectURI = SINAWEIBO_REDIRECTURI ;
//http://open.weibo.com/wiki/Scope

request.userInfo = @{@"flag": @"authorize"};
[WeiboSDK sendRequest:request];

userHandler(state, note.object);
[[NSNotificationCenter defaultCenter] removeObserver:observer];
}];
}
}
+ (void)wechatLogin {
if ([WXApi isWXAppInstalled]){
//构造SendAuthReq结构体
SendAuthReq* req = [[SendAuthReq alloc ] init];
req.scope = @"snsapi_userinfo" ;
req.state = @"Gengmei" ;
//第三方向微信终端发送一个SendAuthReq消息结构
[WXApi sendReq:req];
}
}

[GMThirdPartyOauthManager shareInstance].tencentOAuth = [[TencentOAuth alloc] initWithAppId:QQ_APPID andDelegate:[GMThirdPartyOauthManager shareInstance]];
}
}
授权操作结束后，从第三方App回到自己的App会收到一系列的回调,统一在GMThirdPartyOauthManager中处理

{
static dispatch_once_t onceToken;
static id instance = nil;
dispatch_once(&onceToken, ^{

});
return instance;
}

}
return self;
}
