iPhone X / iOS 11 toolbar support on sample

[bernaferrari]

I am having issues with the toolbar on Sample on the latest iOS version, example:

ZFPlayer fixed this a few days ago. -> https://github.com/renzifeng/ZFPlayer/commit/358fd430bf9e9669dce7f7886bbb4e1dfdbf7d1e + https://github.com/renzifeng/ZFPlayer/commit/f471b5e6e3077adf7c973b3a5d6dc8b35e54fcb8 Also, they fixed the samples not working because the source was offline -> https://github.com/renzifeng/ZFPlayer/commit/3be443c6457553ef6e61cb9fd9e9aa7f6079480a
