Question

Just to first say that I’m a total coding noob and so I’m probably trying to do something above my knowledge level. I went online and sought code for adding a video to an x-code program. I tried various different online tutorials and none of them worked.
I tried at first to program it into Xcode 4.2 but to no avail. I then downloaded the latest version 4.5

The build succeeds in the iphone6 simulator but then it fails to actually run.

The error message I’m getting is a SIGABERT:- * Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘* -[NSURL initFileURLWithPath:]: nil string parameter’

My header file is:-

#import UIkit/UIkit.h (with the smaller than larger than symbols)

#import MediaPlayer/MediaPlayer.h (with the smaller than larger than symbols)

@interface ViewController :UIViewController {

}

-(IBAction)playvideo;

@end

My implementation file is:-

#import "ViewController".h
#import <UIKit/UIKit.h>


@implementation ViewController


-(IBAction)playvideo {
 NSURL *url = [NSURL fileURLWithPath:
              [[NSBundle mainBundle] pathForResource:@"jamcookvid1" ofType:@"mv4"]];

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

[[self navigationController]presentMoviePlayerViewControllerAnimated:
 playercontroller];
playercontroller.moviePlayer.movieSourceType = MPMovieSourceTypeFile;

[playercontroller.moviePlayer play];
// [playercontroller release];
playercontroller = nil;

}

@end

If any of you guys could help me – it would be much appreciated. JB

It’s likely that your file doesn’t exist in the app bundle…or not with that exact spelling. Try logging the result of [[NSBundle mainBundle] pathForResource:@"jamcookvid1" ofType:@"mv4"]. You will probably find it’s nil, which would explain the message.
