【问题描述】：

我正在尝试循环播放本地视频，但我一直遇到问题。 iphone 模拟器构建将成功，但视频不会播放或循环。我正在制作一个在 LaunchImage 之后循环播放视频的应用程序。和MPMoviePlayerController有关系吗？

代码如下： ViewController.h

#import <UIKit/UIKit.h>
#import <MediaPlayer/MediaPlayer.h>

@interface ViewController : UIViewController

@end

ViewController.m

#import "ViewController.h"

@interface ViewController ()
@property (strong, nonatomic) MPMoviePlayerController *moviePlayer;

@end

@implementation ViewController
@synthesize moviePlayer;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSString*thePath=[[NSBundle mainBundle] pathForResource:@"ColoredDiamond" ofType:@".mp4"];
    NSURL*theurl=[NSURL fileURLWithPath: thePath];

    self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:theurl];
    [self.moviePlayer.view setFrame:CGRectMake(40,197,240,160)];
    [self.moviePlayer prepareToPlay];
    [self.moviePlayer setShouldAutoplay:YES];
    [self.view addSubview:self.moviePlayer.view];

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(playBackFinished:) name:MPMoviePlayerPlaybackDidFinishNotification object:moviePlayer];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

/* - (void) playbackFinished: (NSNotification*) notification{
    NSLog(@"playBackFinished");
    if(moviePlayer){
        [moviePlayer play];
    }
}
*/

@end

【解决方案1】：

self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:theurl];
[self.moviePlayer.view setFrame:CGRectMake(40,197,240,160)];
[self.moviePlayer prepareToPlay];

[self.moviePlayer setRepeatMode:MPMovieRepeatModeOne];

[self.moviePlayer setShouldAutoplay:YES];
[self.view addSubview:self.moviePlayer.view];

RepeatMode 确定电影播放器如何重复播放电影。

@property (nonatomic) MPMovieRepeatMode repeatMode

此属性的默认值为MPMovieRepeatModeNone。

可用的重复模式列表，

 MPMovieRepeatModeNone,
 MPMovieRepeatModeOne

适用于 iOS 3.2 及更高版本。
