前言: 首先你要明白, 这种集成三方的东西, 都非常简单,可能会有坑, 填上就好, 这篇文章以微博为例, 其实都是一样的. 步骤或繁或简单, 习惯就好.

1. 首先在微博开放平台注册成为开发者http://open.weibo.com

2. 创建应用

3. 完善应用信息, 这里需要注意的是Bundle ID需要与应用一致, 同时记录appKey 项目中会用到

4. 在应用信息-高级信息中

与上方的保持一致---这段代码后面后使用到

5. 填写URL Types

6. 配置info.plist同时加入白名单

 <array>
  <string>sinaweibohd</string>
  <string>sinaweibo</string>
  <string>weibosdk</string>
  <string>weibosdk2.5</string>
 </array>

7. 导入SDK.

7.1 使用cocoapods你可以这样

pod "WeiboSDK", :git => "https://github.com/sinaweibosdk/weibo_ios_sdk.git"

7.2 或者直接下载拖入工程

8. 代码

// AppDelegate中
#import <WeiboSDK.h>
#define WB_iOS_Key @""
@interface AppDelegate ()<WeiboSDKDelegate>

   /**
     *  1. 设置WeiboSDK的调试模式
     *  2. 注册
     */
    [WeiboSDK enableDebugMode:YES];
    [WeiboSDK registerApp:WB_iOS_Key];

#pragma mark - WeiboSDKDelegate
- (void)didReceiveWeiboRequest:(WBBaseRequest *)request
{

}
// 根据自己的需求写回调
// 这是微博Demo提供的代码
- (void)didReceiveWeiboResponse:(WBBaseResponse *)response
{
if ([response isKindOfClass:WBSendMessageToWeiboResponse.class])
    {
        NSString *title = NSLocalizedString(@"发送结果", nil);
        NSString *message = [NSString stringWithFormat:@"%@: %d\\n%@: %@\\n%@: %@", NSLocalizedString(@"响应状态", nil), (int)response.statusCode, NSLocalizedString(@"响应UserInfo数据", nil), response.userInfo, NSLocalizedString(@"原请求UserInfo数据", nil),response.requestUserInfo];

        WBSendMessageToWeiboResponse* sendMessageToWeiboResponse = (WBSendMessageToWeiboResponse*)response;
        NSString* accessToken = [sendMessageToWeiboResponse.authResponse accessToken];
        if (accessToken)
        {
            self.wbtoken = accessToken;
        }
        NSString* userID = [sendMessageToWeiboResponse.authResponse userID];
        if (userID) {
            self.wbCurrentUserID = userID;
        }
    }
    else if ([response isKindOfClass:WBAuthorizeResponse.class])
    {
        NSString *title = NSLocalizedString(@"认证结果", nil);
        NSString *message = [NSString stringWithFormat:@"%@: %d\\nresponse.userId: %@\\nresponse.accessToken: %@\\n%@: %@\\n%@: %@", NSLocalizedString(@"响应状态", nil), (int)response.statusCode,[(WBAuthorizeResponse *)response userID], [(WBAuthorizeResponse *)response accessToken],  NSLocalizedString(@"响应UserInfo数据", nil), response.userInfo, NSLocalizedString(@"原请求UserInfo数据", nil), response.requestUserInfo];
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
                                                        message:message
                                                       delegate:nil
                                              cancelButtonTitle:NSLocalizedString(@"确定", nil)
                                              otherButtonTitles:nil];

        self.wbtoken = [(WBAuthorizeResponse *)response accessToken];
        self.wbCurrentUserID = [(WBAuthorizeResponse *)response userID];
        self.wbRefreshToken = [(WBAuthorizeResponse *)response refreshToken];
        [alert show];
    }
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    return [WeiboSDK handleOpenURL:url delegate:self];
}

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
    return [WeiboSDK handleOpenURL:url delegate:self ];
}

9. 写个登陆按钮登陆

- (void)loginClick
{
    [[[[UIApplication sharedApplication] delegate] window] makeKeyWindow];

    WBAuthorizeRequest *request = [WBAuthorizeRequest request];
    // 前面提到的
    request.redirectURI = kRedirectURI;
    request.scope = @"all";
    request.userInfo = @{@"SSO_From": @"SendMessageToWeiboViewController",
                         @"Other_Info_1": [NSNumber numberWithInt:123],
                         @"Other_Info_2": @[@"obj1", @"obj2"],
                         @"Other_Info_3": @{@"key1": @"obj1", @"key2": @"obj2"}};
    [WeiboSDK sendRequest:request];
}

10. 完成图

状态0 代表成功. 如果回忆没有错基本就成功了. O.-
