我的微信登錄按鈕下的代碼，就是從官網(wǎng)里拷貝的。

UMSocialSnsPlatform *snsPlatform = [UMSocialSnsPlatformManager getSocialPlatformWithName:UMShareToWechatSession];

snsPlatform.loginClickHandler(self,[UMSocialControllerService defaultControllerService],YES,^(UMSocialResponseEntity *response){

if (response.responseCode == UMSResponseCodeSuccess) {

UMSocialAccountEntity *snsAccount = [[UMSocialAccountManager socialAccountDictionary]valueForKey:UMShareToWechatSession];

NSLog(@"username is %@, uid is %@, token is %@ url is %@",snsAccount.userName,snsAccount.usid,snsAccount.accessToken,snsAccount.iconURL);

}

});

然后，點登錄按鈕時就崩潰，出錯信息如下：

+[WXApi sendAuthReq:viewController:delegate:]: unrecognized selector sent to class 0x1004dd558

libc++abi.dylib: terminate_handler unexpectedly threw an exception

QQ登錄和微博登錄都沒問題。SDK版本是4.2.3

最后的解決方法：友盟的sdk和share的sdk沖突，項目里面刪除share的sdk就可以了
