2.分析
大概都分3步，发送请求并回调，回调中处理返回结果，根据返回结果再去请求下一步。
3.info.plist里配置对应URL types
4.代码

#import "WeiboSDK.h"

6.最后，调用发送授权请求，在所需要的viewController
- (IBAction)loginQq:(id)sender
{
_oauthQQ = [[TencentOAuth alloc] initWithAppId:kTencentAppKey andDelegate:self];
NSArray * permissions = @[@"get_user_info", @"get_simple_userinfo", @"add_t"];
[_oauthQQ authorize:permissions];
}
- (IBAction)loginWeixin:(id)sender
{
SendAuthReq* req =[[SendAuthReq alloc ] init];
req.scope = @"snsapi_userinfo,snsapi_base";
req.state = @"fandian0722" ;
[WXApi sendReq:req];
}
- (IBAction)loginWeibo:(id)sender;
{
WBAuthorizeRequest *request = [WBAuthorizeRequest request];
request.redirectURI = @"http://";
request.scope = @"all";
[WeiboSDK sendRequest:request];
}
