MPMoviePlayer setCurrentPlaybackTime iOS [英] MPMoviePlayer setCurrentPlaybackTime iOS

问题描述

我使用 MPMoviePlayer 播放视频，我遇到的问题是，当用户按下设备的 home 按钮时，我保存了视频的当前位置，而不是当他再次午餐应用程序时，我希望他从他离开的地方开始，所以我使用 setCurrentPlaybackTime 函数，它在 iOS 5中非常有效 ，但不在视频从头开始的 iOS 5.1 中.

任何人都可以解决此类问题吗?

解决方案

我的问题已解决，我将解释到目前为止我所做的事情.

当我找不到该行为的解决方案/解释时(我觉得很奇怪)，我开始进行大量的日志记录，所以我注意到的是当我记录当前位置时(在iOS 5.1中) )

  currentPlaybackTime = nan

但是在iOS 5中，我的正常值为0.00000

因此我设置了一个计时器(重复执行)以每次记录当前时间，因此我注意到它从 nan 更改为 0.00000

我得出的结论是，我需要在设置PlaybackTime之前稍等一会(不明白为什么)，所以在等待1 ms (1/1000 s )，并且可以正常工作.

I use MPMoviePlayer to play my video, the problem I have is when the user press the home button of the device, I save the current position of the video, than when he lunch the application again I would like him to start from where he left, so I use setCurrentPlaybackTime function, it works perfectly in iOS 5 but not in iOS 5.1 where the video starts from the beginning.

Does any body have a solution for this kind of problem ?

解决方案

My problem is solved and I will explain what I've done so far.

When I couldn't find a solution/explanation of that behavior (which I find it strange) I start making lot and lot of logging, so what I noticed is when I log the current position I get always (in iOS 5.1)

  currentPlaybackTime = nan

but in iOS 5 I got a normal value as 0.00000

so I made a timer (which repeats itself) to log every time the current time, so I noticed that its changing from nan to 0.00000 after a while

The conclusion I made is that I need to wait a bit (don't understand why) before setting the PlaybackTime, and so it is, after waiting 1 ms (1/1000 s) and it works.
