视频
一般用MPMoviePlayerController（需要导入MediaPlayer.Framework），还有一种是使用AVPlayer.但在iOS9,苹果将要弃用MPMoviePlayerController,所以推荐使用AVPlayer.
注: 区别:MPMoviePlayerController,简单易用,通过通知监听状态,添加到View上;
AVPlayer复杂,灵活,需要自定义UI实现,需要添加到layer上;
MPMoviePlayerController
一.基本播放视频
//懒加载
- (MPMoviePlayerViewController *)playerVc
{
if (_playerVc == nil) {
NSURL *url = [NSURL URLWithString:self.movie.videourl];
_playerVc = [[JDMMoviePlayerViewController alloc] initWithContentURL:url];
_playerVc.moviePlayer.scalingMode = MPMovieScalingModeAspectFit;
_playerVc.moviePlayer.controlStyle = MPMovieControlStyleDefault ;
[_playerVc.moviePlayer prepareToPlay];
[_playerVc.moviePlayer play];
}
return _playerVc;
}
//设置数据
self.playerVc.view.frame = CGRectMake(0, 0, JDMScreenW, _playMovieView.height);
[self.scrollView addSubview: self.playerVc.view];
[[UIApplication sharedApplication] setStatusBarHidden:NO];
二.MPMoviePlayerController全屏模式下横屏与竖屏切换
- 1.都在AppDelegate文件中实现
AppDelegate.h文件中引入MediaPlayer头文件
#import <MediaPlayer/MediaPlayer.h>
- 2.声明记录当前应用状态变量
@implementation AppDelegate
{
BOOL _isFullScreen;
}
- 3.在application:didFinishLaunchingWithOptions:中注册进入全屏和退出全屏消息事件
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(willEnterFullScreen:)
name:MPMoviePlayerWillEnterFullscreenNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(willExitFullScreen:)
name: MPMoviePlayerWillExitFullscreenNotification object:nil];
- 4.实现上面消息对应的事件响应函数
- (void)willEnterFullScreen:(NSNotification *)notification
{
_isFullScreen = YES;
}
- (void)willExitFullScreen:(NSNotification *)notification
{
_isFullScreen = NO;
}
- 5.实现application:supportedInterfaceOrientationsForWindow:方法
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
if (_isFullScreen) {
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
} else {
return UIInterfaceOrientationMaskPortrait;
}
注意:MPMoviePlayerController在全屏播放的时候会默认隐藏状态栏,所以需要在全屏结束的时候代码手动显示状态栏,否则导航栏会出现20点的空白
- 1.开始播放的时候
[self.scrollView addSubview: self.playerVc.view];
[[UIApplication sharedApplication] setStatusBarHidden:NO];
- 2.结束全屏的时候
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(willExitFullScreen) name:MPMoviePlayerDidExitFullscreenNotification object:nil];
-(void)willExitFullScreen
{
[[UIApplication sharedApplication] setStatusBarHidden:NO];
}
