我一直在努力让VLC在我的iOS应用程序中工作一段时间.使用Cocoapods,MobileVLCKit被导入到我的项目中.当我现在运行应用程序时,它编译没有问题.但是,当我从MobileVLCKit(MobileVLCKit.h,VLCMediaPlayer.h)中包含任何内容时,应用程序崩溃,告诉我没有找到符号.这是崩溃:

我正在开发的应用程序仅支持纵向模式.但是,在iOS8中,现在已弃用的UIAlertView可以进入横向并显示其他一些小问题.为了解决这个问题,我决定UIAlertController尝试一下.它有效,但我有一个新问题仍然有点烦人.警报不再进入景观,但确实以视差运动为特色.我在UIAlertController视图中添加了一个标签和一个图像,但那些不具有视差的东西,这意味着当用户移动手机时它看起来很奇怪.

我正在寻找两种选择,但我找不到如何做其中任何一种.
第一个解决方案是禁用视差,看看我们如何在应用程序的任何地方不支持它.
第二种解决方案是将视差支持添加到标签和图像.
无论如何,这是一段代码:

UIAlertController *welcomeAlertController = [UIAlertController
                                              alertControllerWithTitle:[NSString stringWithFormat:NSLocalizedString(@"Would you like to send %@ a message?", @"This message is displayed after adding a new message receiver. The %@ is the name of the receiver."), self.receiver.name]
                                              message:@"\n\n\n\n\n\n\n\n"
                                              preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction *cancelAction = [UIAlertAction
                               actionWithTitle:NSLocalizedString(@"Skip", @"Skip: meaning user can skip a certain step.")
                               style:UIAlertActionStyleCancel
                               handler:^(UIAlertAction *action)
                               {
                                   [self cancelButtonPressed];
                               }];

UIAlertAction *okAction = [UIAlertAction
                           actionWithTitle:NSLocalizedString(@"Send", @"Send: meaning user can send information to somewhere.")
                           style:UIAlertActionStyleDefault
                           handler:^(UIAlertAction …
