微信分享
1、注册第三方软件 + (BOOL) registerApp:(NSString *) appidwithDescription:(NSString *) appdesc
2、使appDelegate成为代理 + (BOOL) handleOpenURL: (NSURL *) urldelegate:(id< WXApiDelegate >) delegate
a、参数url 微信启动第三方应用时传递过来的url
b、参数delegate WXApiDelegate对象
3、发送消息给微信 + (BOOL) sendReq:(BaseReq *) req
a、函数调用后，会切换到微信的界面。第三方应用程序等待微信返回onResp。微信在异步处理完成后一定会调用onResp。支持以下类型 SendAuthReq、SendMessageToWXReq等。
b、BaseReq 基类 可以使用下面的三个子类
4、发送请求后等待微信响应，第一次交互。接收到微信传来的数据后，系统会自动调用
- (void)onResp:(BaseResq *)resp 可选方法
5、- (void)onResp:(BaseResq *)resp 显示微信返回的信息
示例代码：
AppDelegate.h两个重要方法：
//如果第三方程序向微信发送了sendReq的请求，那么onResp会被回调。sendReq请求调用后，会切到微信终端程序界面
- (void)onResp:(id)resp{
// QQ的
if ([resp isKindOfClass:[QQBaseResp class]]) {
}
else if ([resp isKindOfClass:[SendAuthResp class]]) {
SendAuthResp *aresp = (SendAuthResp *)resp;
/*
ErrCode ERR_OK = 0(用户同意)
ERR_AUTH_DENIED = -4（用户拒绝授权）
ERR_USER_CANCEL = -2（用户取消）
code 用户换取access_token的code，仅在ErrCode为0时有效
state 第三方程序发送时用来标识其请求的唯一性的标志，由第三方程序调用sendReq时传入，由微信终端回传，state字符串长度不能超过1K
lang 微信客户端当前语言
country 微信用户当前国家信息

QQ分享1.在工程中添加QQ互联IOS SDK2.生成分享的QQApiObject3.生成sendReq发送消息4.通过判断SendReq方法的返回值，查看是否成功调用定向分享5.查看分享出去的消息#import//构造QQ分享内容
