跪求iOS开发的新浪微博授权登录，要求源码实现.

1.首先你要有新浪开发者账号，无非是到开放平台建立一个项目，然后把你的账号添加进去，你创建的项目中有app key，app secret以及授权跳转地址uri，还要在工程中导入新浪SDK
AppDelegate.h
#import "SinaWeibo.h"
#define kAppKey

#define kAppSecret

#define kAppRedirectURI
宏后面对应你的app key，app secret以及授权跳转地址uri
AppDelegate..m
//初始化新浪微博对象

• (void)_initSinaWeibo
  {
  _sinaweibo = [[SinaWeibo alloc] initWithAppKey:kAppKey appSecret:kAppSecret appRedirectURI:kAppRedirectURI andDelegate:self];

  //读取本地保存的认证信息
  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"];

  NSLog(@"读取本地授权信息成功");
  

  }

}

#pragma mark -SinaWeibo delegate

• (void)sinaweiboDidLogIn:(SinaWeibo *)sinaweibo { 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];

}
在你需要登录的视图控制器里面
写如下方法

• (SinaWeibo *)sinaweibo { AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate; return delegate.sinaweibo; } 登陆的地方写，在相同视图控制器里面 //打开授权界面登陆 [self.sinaweibo logIn];

//注销账号
//删除新浪的认证信息
[[NSUserDefaults standardUserDefaults] removeObjectForKey:@"SinaWeiboAuthData"];
[[NSUserDefaults standardUserDefaults] synchronize];

参考 iOS 新浪微博客户端Demo实践之（一）OAuth2.0认证
