iOS sdk中可以使用MPMoviePlayerController来播放电影文件。但是在iOS设备上播放电影文件有严格的格式要求，只能播放下面两个格式的电影文件。
? H.264 (Baseline Profile Level 3.0)
? MPEG-4 Part 2 video (Simple Profile)
幸运的是你可以先使用iTunes将文件转换成上面两个格式。
MPMoviePlayerController还可以播放互联网上的视频文件。但是建议你先将视频文件下载到本地，然后播放。如果你不这样做，iOS可能会拒绝播放很大的视频文件。
#import <UIKit/UIKit.h>
#import <MediaPlayer/MediaPlayer.h>
@interface ViewController :UIViewController
@property(nonatomic,retain)NSString *selectedName;
@property(nonatomic,retain)MPMoviePlayerController *moviePlayer;
@end
#import "ZKChoiseMoveViewController.h"，它是新建的一个类，用来展示视频列表
-(void)viewWillAppear:(BOOL)animated{

tableView.dataSource =self;
tableView.tag =TABLE_TAG;
[self.viewaddSubview:tableView];

// Do any additional setup after loading the view.
}
#pragma mark tableviewdatasource
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *str =@"identifier";
UITableViewCell *cell = [tableViewdequeueReusableCellWithIdentifier:str];
if (!cell) {
cell = [[UITableViewCellalloc]initWithStyle:UITableViewCellStyleDefaultreuseIdentifier:str];
//加视频标题
cell.textLabel.text = [self.arrobjectAtIndex:[indexPath row]];
}
return cell;
}
#pragma mark tableviewdelegate
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
[[NSNotificationCenterdefaultCenter]postNotificationName:@"moviename"object:[self.arrobjectAtIndex:[indexPath row]]];
[selfdismissViewControllerAnimated:YEScompletion:nil];
}
还有一个MPMoviePlayerViewController类，用于全屏播放视频文件，用法和MPMoviePlayerController一样。
