Question

我想在应用程序的游戏结束时播放一段短片，我将如何完成它？有关MPMovieplayer的任何教程吗？

感谢您回答我的问题

欢呼声

我目前有这些代码，如何在应用中播放它而不会弹出youtube界面？

NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"EndVideo" ofType:@"m4v"]];

MPMoviePlayerViewController * playercontroller = [[MPMoviePlayerViewController alloc] initWithContentURL:url];

[self presentMoviePlayerViewControllerAnimated:playercontroller];

playercontroller.moviePlayer.movieSourceType = MPMovieSourceTypeFile;
[playercontroller.moviePlayer play];
[playercontroller release]; playercontroller = nil;

I am playing a movie stored on server.Even if you have local file you can convert the path to NSURL & use it


    Create a NSObject class CustomMoviePlayerViewController

In the .h file 

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


@interface CustomMoviePlayerViewController : UIViewController 
{ 
    MPMoviePlayerController *mp;
    NSURL *movieURL;

}


- (id)initWithPath:(NSString *)moviePath;
- (void)readyPlayer;

@end

In the .m file

//
//  CustomMoviePlayerViewController.m
//

#import "CustomMoviePlayerViewController.h"

#pragma mark -
#pragma mark Compiler Directives & Static Variables

@implementation CustomMoviePlayerViewController

-(void)viewWillDisappear:(BOOL) animated
{  



    if(mp) {
        [mp stop];
    }


}



- (id)initWithPath:(NSString *)moviePath
{ 
    mp.controlStyle =  MPMovieControlStyleNone;
    // Initialize and create movie URL
    if (self = [super init])
    {
        movieURL = [NSURL fileURLWithPath:moviePath];    
        [movieURL retain];

    }
    return self;
}


- (void) moviePlayerLoadStateChanged:(NSNotification*)notification 
{   

        [mp setControlStyle:MPMovieControlStyleFullscreen];

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200
    NSString *deviceModel = [NSString stringWithFormat: @"Device Type: %@\n", [[UIDevice currentDevice] model]];    
    NSRange range = [deviceModel rangeOfString:@"iPad"];


    if(range.location != NSNotFound){
        if ([mp loadState] != MPMovieLoadStateUnknown)
        {
            [[NSNotificationCenter  defaultCenter] removeObserver:self name:MPMoviePlayerLoadStateDidChangeNotification object:nil];

            [[self view] setBounds:CGRectMake(0, 0, 1024, 748)];


            UIInterfaceOrientation interfaceOrientation = [self interfaceOrientation];
            if(interfaceOrientation == UIInterfaceOrientationLandscapeLeft ){

                [[mp view] setFrame:CGRectMake(0, 0, 480, 320)];

            }
            else if(interfaceOrientation == UIInterfaceOrientationLandscapeRight ){

whenever you want to play the file


    NSString *movieFile=[[NSBundle mainBundle] pathForResource:@"test" ofType:@"mp4"];

    // Create custom movie player   
    moviePlayer = [[[CustomMoviePlayerViewController alloc] initWithPath:movieFile] autorelease];

    [self presentModalViewController:moviePlayer animated:NO];
    [moviePlayer readyPlayer];

还要将MediaPlayer.framework添加到项目中

如何在应用中播放电影？
