我们使用苹果自带的视频播放框架来播放一般的视频，一些专业的视频播放器则要使用第三方开源框架。

// PlayerViewController.h

// MPMoviePlayerDemo

#import

@interface PlayerViewController : MPMoviePlayerViewController

@end

// PlayerViewController.m

#import "PlayerViewController.h"

@interface PlayerViewController ()

@implementation PlayerViewController

//---------------6.0之后使用一下两个方法控制横屏、竖屏--------------------------

- (BOOL)shouldAutorotate {

return YES;

}

- (NSUInteger)supportedInterfaceOrientations {

return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;

}

//6.0之前用于控制横、竖

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {

if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft) {

return YES;

}

return NO;
