因此,根据我们之前的检查,我们将按钮连接起来以显示图像/视频/音频。那部分工作正常。它知道要播放哪一个,但是,当我们点击视频和音频按钮时,没有任何反应。图像效果很好。
视频和音频正在网上拍摄,它们不是本地的,但到处都说这仍然是可能的。以下是我们播放这两个文件的代码片段:
if ( [fName hasSuffix:@".png"])
{
NSLog(@"PICTURE");
NSURL *url = [NSURL URLWithString:
fName];
UIImage *image = [UIImage imageWithData: [NSData dataWithContentsOfURL:url]];
self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
// self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"MainBG.jpg"]];
[self.view addSubview:[[UIImageView alloc] initWithImage:image]];
}
if ( [fName hasSuffix:@".mp4"])
{
NSLog(@"VIDEO");
//NSString *path = [[NSBundle mainBundle] pathForResource:fName ofType:@"mp4"];
//NSLog(path);
NSURL *url = [NSURL fileURLWithPath:fName];
MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:url];
[player play];
}
if ( [fName hasSuffix:@".mp3"])
{
NSLog(@"AUDIO");
NSURL *url = [NSURL fileURLWithPath:fName];
NSData *soundData = [NSData dataWithContentsOfURL:url];
AVAudioPlayer *avPlayer = [[AVAudioPlayer alloc] initWithData:soundData error: nil];
[avPlayer play];
}
看错了什么?顺便说一下,它编译并运行,但是当我们点击执行该代码的按钮时没有任何反应。
答案 0 :(得分:0)
我不确定他们为什么不玩,有没有达到视频和音频条件?
在您播放电影之前,您目前失踪的方式
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(movieFinishedCallback:)
name:MPMoviePlayerPlaybackDidFinishNotification object:player];
然后您将需要该函数来处理回调
-(void)movieFinishedCallback:(NSNotification *)notification{
NSLog(@"MOVIE FINISHED");
if(player == [notification object]){
[[NSNotificationCenter defaultCenter] removeObserver:self
name:MPMoviePlayerPlaybackDidFinishNotification object:player];
[player release];
player = nil;
}
}
