设置了 initialPlaybackTime 属性后, 视频(HTTP 流媒体)仍从开头播放。
iOS <= 8.3 中相同的代码可以正常工作:
self.moviePlayer.initialPlaybackTime = self.lastPlaybackTime;
[self.moviePlayer play];
设置了 initialPlaybackTime 属性后, 视频(HTTP 流媒体)仍从开头播放。

self.moviePlayer.initialPlaybackTime = self.lastPlaybackTime;
[self.moviePlayer play];
BOOL playbackDurationSet = NO;
- (void)moviePlayerPlaybackStateChanged:(NSNotification*)notification
{
MPMoviePlayerController* player = (MPMoviePlayerController*)notification.object;
switch ( player.playbackState ) {
case MPMoviePlaybackStatePlaying:
if(!playbackDurationSet){
[self.moviePlayer setCurrentPlaybackTime:yourStartTime];
playbackDurationSet = YES;
}
break;
}
}
- (void)moviePlayerPresented
{
playbackDurationSet = NO;
}
我也遇到了一些这样的问题。由于MPMoviePlayerController在iOS 9中被弃用,它们不太可能得到修复。
hariszaman的答案对我有用:
- (void)moviePlaybackStateChanged:(NSNotification*)notif
{
//...
if (self.videoPlayer.playbackState == MPMoviePlaybackStatePlaying) {
if (self.currentBookmark) {
if ([[PSDeviceInfo sharedInstance] is_iOSatLeast84]){
NSTimeInterval toTime = [self.currentBookmark.seconds doubleValue];
[self.videoPlayer setCurrentPlaybackTime:toTime];
self.currentBookmark = nil;
}
}
}
if (self.videoPlayer.playbackState == MPMoviePlaybackStatePaused) {
//...
}
if (self.videoPlayer.playbackState == MPMoviePlaybackStateStopped) {
//...
}
}
另外:
- (void)configureMoviePlayer
{
if (self.currentBookmark) {
if ([[PSDeviceInfo sharedInstance] is_iOSatLeast84]){
// will set start after did start
}else {
NSTimeInterval toTime = [self.currentBookmark.seconds doubleValue];
self.videoPlayer.initialPlaybackTime = toTime;
self.currentBookmark = nil;
}
}
else {
self.videoPlayer.initialPlaybackTime = 0;
}
//...
}
方法 is_iOSatLeast84:
- (BOOL)is_iOSatLeast84
{
// version 8.4
NSString *version = [[UIDevice currentDevice] systemVersion];
BOOL isAtLeast84 = [version floatValue] >= 8.35;
return isAtLeast84;
}
