This is my first real project. I have an app that captures several seconds of video using AVFoundation, outputs this to a file in the documents directory and lets the user preview the video before they upload it using HTTP and a PHP script on my website.
All the video capture and preview work perfectly but I am stuck on uploading the video file.
I learnt a lot from this simpleSDK video which shows how to achieve the desired effect using a video file stored in the apps main bundle.
The code from the tutorial that set up videoData ready to upload originally looked like this:
NSData *videoData = [NSData dataWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"Movie" ofType:@"mov"]];
NSString *urlString = @"http://www.iphonedevnation.com/video-tutorial/upload.php";
The filename of the video file that I need to upload is always unique and generated using CFUUIDCreateString. I join this string to the path for the documents directory, add ".mov" to the end of it and save it into a text file for retrieving later.
This all works as I am able to retrieve the filename from the file and use it to preview the movie clip elsewhere in the app.
My path is in an NSString, that I have tried converting to NSURL and removing the file suffix to get it to work with the NSData *videoData.........line but it doesn't compile, I get an "No known class method for selector 'dataWithContentsOfFile:ofType.' error. I am targeting iOS 5 and using Xcode 4.3 with ARC and Storyboards.
I've been at this for best part of 5 hours now so hopefully someone can help. My code, which included tips from elsewhere on converting from a NSString to NSURL follows:
NSString *content = [[NSString alloc] initWithContentsOfFile:lastSavedTalentFilenamePath
usedEncoding:nil
error:nil];
NSLog(@"content=%@",content);
//Need to now remove the '.mov' file type identifier
NSString *shortContent= [content substringToIndex:[content length]-4];
NSLog(@"***************shortContent***************%@", shortContent);
NSURL *convertedContent = [NSURL fileURLWithPath:shortContent];
NSLog(@"***************convertedContent***********%@",convertedContent);
NSData *videoData = [NSData dataWithContentsOfFile:convertedContent ofType:@"mov"];];
There is no NSData method called dataWithContentsOfFile:ofType:
The methods available are:
+ dataWithContentsOfFile:
+ dataWithContentsOfFile:options:error:
both of which take the file location as an NSString so there's not need to convert to an NSURL
