友盟This application is modifying

This application is modifying the autolayout engine from a background thread, which can lead to engine corruption and weird crashes. This will cause an exception in a future release.

把弹出友盟的方法放到主线程就行了

//打开umeng分享面板
dispatch_async(dispatch_get_main_queue(), ^{
[UMSocialUIManager showShareMenuViewInWindowWithPlatformSelectionBlock:^(UMSocialPlatformType platformType, NSDictionary *userInfo) {

        //创建分享消息对象
        UMSocialMessageObject *messageObject = [UMSocialMessageObject messageObject];
        //设置文本
        messageObject.text = [dic objectForKey:@"title"];
        
        //调用分享接口
        [[UMSocialManager defaultManager] shareToPlatform:platformType messageObject:messageObject currentViewController:self completion:^(id data, NSError *error) {
            if (error) {
                NSLog(@"************Share fail with error %@*********",error);
            }else{
                NSLog(@"response data is %@",data);
            }
        }];
        
        
    }];

});
