//初始化weiboApi

tencent=[[WeiboApi alloc]initWithAppKey:tencentAppKey andSecret:tencentkAppSecret andRedirectUri:tencentkAppReddirectURI andAuthModeFlag:0 andCachePolicy:0]

//通过auth2.0代理登录

 [tencent loginWithDelegate:self andRootController:self]
//代理成功，回调方式

- (void)DidAuthFinished:(WeiboApi *)wbapi_
{
    NSString  *str=@"";
    UIImage *pic = [UIImage imageNamed:@"install.png"];
    NSMutableDictionary *params = [[NSMutableDictionary alloc]initWithObjectsAndKeys:@"json",@"format",str, @"content",pic, @"pic",nil];
    [tencent requestWithParams:params apiName:@"t/add_pic" httpMethod:@"POST" delegate:self];
}

这儿有一个不太清楚的地方，即tencentkAppReddirectURI回调地址，该回调地址是：
　　“我的应用》应用XXX》基本信息》应用网址”
