wie man ein Video im iphone streamt

Question

tut initWithContentURL: in MPMoviePlayerController zuerst die Videodatei herunterladen und dann anfangen zu spielen oder wird es streamen Datei wie in youtube?

Ich möchte ein Video im Server durch Streaming wiedergeben, um Zeit zu verschwenden.

So führen Sie Streaming im iPhone durch? Kann mir bitte jemand vorschlagen, wenn Sie es wissen.

Vielen Dank im Voraus.

NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 

if (!documentsDirectory) { 
    NSLog(@"Documents directory not found!"); 
} 
NSString *appFile; 
NSArray *myWords = [[NSString stringWithFormat:@"%@",[[videolistArray objectAtIndex:[number intValue]] valueForKey:@"video"]] componentsSeparatedByCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"/"]]; 
appFile = [documentsDirectory stringByAppendingPathComponent:[myWords lastObject]]; 
NSFileManager *fileMgr=[NSFileManager defaultManager]; 
if (![fileMgr fileExistsAtPath:appFile]) { 
    NSData *imageData; 
    NSURL *imageURL = [[[NSURL alloc] initWithString:[[videolistArray objectAtIndex:[number intValue]] valueForKey:@"video"] ] autorelease]; 
    if (imageURL) { 
     imageData = [NSData dataWithContentsOfURL:imageURL]; 
    } 

    [imageData writeToFile:appFile atomically:YES]; 
} 
[pool release]; 


if (spinner) { 
    [spinner stopAnimating]; 
    [spinner removeFromSuperview]; 
    [spinner release]; 
    spinner = nil; 
}
