微信分享
1、注冊第三方軟件 + (BOOL) registerApp:(NSString *) appidwithDescription:(NSString *) appdesc
2、使appDelegate成為代理 + (BOOL) handleOpenURL: (NSURL *) urldelegate:(id< WXApiDelegate >) delegate
a、參數url 微信啟動第三方應用時傳遞過來的url
b、參數delegate WXApiDelegate對象
3、發送消息給微信 + (BOOL) sendReq:(BaseReq *) req
a、函數調用后，會切換到微信的界面。第三方應用程序等待微信返回onResp。微信在異步處理完成后一定會調用onResp。支持以下類型 SendAuthReq、SendMessageToWXReq等。
b、BaseReq 基類 可以使用下面的三個子類
4、發送請求后等待微信響應，第一次交互。接收到微信傳來的數據后，系統會自動調用
- (void)onResp:(BaseResq *)resp? 可選方法
5、- (void)onResp:(BaseResq *)resp 顯示微信返回的信息
示例代碼：
AppDelegate.h兩個重要方法：
//如果第三方程序向微信發送了sendReq的請求，那么onResp會被回調。sendReq請求調用后，會切到微信終端程序界面
- (void)onResp:(id)resp{
// QQ的
if ([resp isKindOfClass:[QQBaseResp class]]) {
}
else if ([resp isKindOfClass:[SendAuthResp class]]) {
SendAuthResp *aresp = (SendAuthResp *)resp;
/*

code? ? 用戶換取access_token的code，僅在ErrCode為0時有效
