//AppDelegate.h文件
//宏定义
#define kAppKey             @"略"
#define kAppSecret           @"略"
#define kAppRedirectURI      @"略"

//属性设置
@property (readonly, nonatomic) SinaWeibo *sinaweibo;

//AppDelegate.m文件
#pragma mark - 集成新浪SDK
    
    //创建新浪对象
    _sinaweibo = [[SinaWeibo alloc] initWithAppKey:kAppKey appSecret:kAppSecret appRedirectURI:kAppRedirectURI andDelegate:self];
    
    //存储数据
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSDictionary *sinaweiboInfo = [defaults objectForKey:@"SinaWeiboAuthData"];
    if ([sinaweiboInfo objectForKey:@"AccessTokenKey"] && [sinaweiboInfo objectForKey:@"ExpirationDateKey"] && [sinaweiboInfo objectForKey:@"UserIDKey"])
    {
        _sinaweibo.accessToken = [sinaweiboInfo objectForKey:@"AccessTokenKey"];
        _sinaweibo.expirationDate = [sinaweiboInfo objectForKey:@"ExpirationDateKey"];
        _sinaweibo.userID = [sinaweiboInfo objectForKey:@"UserIDKey"];
    }
    
    return YES;
}

//移除认证信息
- (void)removeAuthData {
    [[NSUserDefaults standardUserDefaults] removeObjectForKey:@"SinaWeiboAuthData"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}

//保存认证数据
- (void)storeAuthData {
    
    NSDictionary *authData = [NSDictionary dictionaryWithObjectsAndKeys:
                              _sinaweibo.accessToken, @"AccessTokenKey",
                              _sinaweibo.expirationDate, @"ExpirationDateKey",
                              _sinaweibo.userID, @"UserIDKey",
                              _sinaweibo.refreshToken, @"refresh_token", nil];
    [[NSUserDefaults standardUserDefaults] setObject:authData forKey:@"SinaWeiboAuthData"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}

- (void)sinaweiboDidLogIn:(SinaWeibo *)sinaweiboz {
    NSLog(@"登陆成功");
    [self storeAuthData];
}

- (void)sinaweiboDidLogOut:(SinaWeibo *)sinaweibo {
    NSLog(@"注销");
    [self removeAuthData];
}

在ViewController页面签订代理协议<SinaWeiboRequestDelegate>
在ViewDidLoad方法里添加下面一段代码

SinaWeibo *sina = [self sinaweibo];
    if (sina.isAuthValid) {
        //请求数据
        [sina requestWithURL:@"statuses/friends_timeline.json" params:nil httpMethod:@"GET" delegate:self];
    
    } else {
        
        [sina logIn];
    }
    

实现它的代理方法

#pragma mark -SinaWeiboRequestDelegate
- (void)request:(SinaWeiboRequest *)request didFailWithError:(NSError *)error;{
   NSLog(@"请求失败");
//    NSLog(@"%@",error);
}

- (void)request:(SinaWeiboRequest *)request didFinishLoadingWithResult:(id)result{
   
   NSLog(@"请求成功");
   NSArray *arr = result[@"statuses"];

}

//获取新浪微博对象
- (SinaWeibo *)sinaweibo
{
   AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
   return delegate.sinaweibo;
}
