-新浪微博 SDK，支持 OAuth 2.0 认证，支持 ARC。
+新浪微博 SDK，支持 OAuth 2.0 认证，支持 ARC。基于官方 SDK [SinaWeiBoSDK2][1] 修改，`WBRequest` 直接使用了官方封装，不支持 ARC，在 ARC 下要添加 `-fno-objc-arc` flag.
+
+#### 使用
+
+1. 在 `WBEngine.m` 修改设置 appKey, appSecret, redirectURL. redirectURL 必须和微博应用设置的授权回调页一致。
+1. Code
+
+    ```objc
+    [[WBEngine sharedWBEngine] setDelegate:self];
+    if ([[WBEngine sharedWBEngine] isLoggedIn]) {
+        [[WBEngine sharedWBEngine] loggedInUserInfo];
+    } else {
+        [[WBEngine sharedWBEngine] logIn];
+    }
+    ```
+
+1. 实现 delegate：
+
+    ```objc
+    #pragma mark - WBEngineDelegate
+    - (void)engineDidLogIn
+    {
+        //login success
+    }
+
+    - (void)engineDidFailLogInWithError:(NSError *)error
+    {
+        //login failed.
+    }
+
+    - (void)engineRequest:(WBRequestType)type didSucceedWithResult:(id)result
+    {
+        if (WBRequestTypeUsersShow == type) {
+            if (result && [result isKindOfClass:[NSDictionary class]]) {
+                //...
+            }
+        }
+    }
+
+    - (void)engineRequest:(WBRequestType)type didFailWithError:(NSError *)error
+    {
+        DLog(@"requestType:%d, error: %@", type, [error description]);
+    }
+    ```
