pathForResource? without using extension (Iphone)

Question

Here is what I\'m doing, when I create an image with the path in the bundle:

UIImage *image = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathFo         


        

Answer 1

You can easily use the NSBundle method without passing the extension, just pass nil for extension.

[[NSBundle mainBundle] pathForResource:@"image.jpg" ofType:nil];

Answer 2

- (NSData *)applicationDataFromFile:(NSString *)fileName {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *appFile = [documentsDirectory stringByAppendingPathComponent:fileName];
    NSData *myData = [[[NSData alloc] initWithContentsOfFile:appFile] autorelease];
    return myData;
}

Could be easily adapted if you wanted it to return a UIImage instead of an NSData.

Also, you don't say if you are saving the images to the documents directory, or adding them to your app bundle before compiling. because if it's the latter, you can use [UIImage imageNamed:(NSString *)filename] to get the image. It expects an extension as part of the file-name.

Answer 3

The easiest way is to store the name and file type in your database separately, and retrieve them using the first method.I'm not sure that you can be successful in implementing the latter one.

Answer 4

I found that with an extension of ".jpg" it was necessary to use ofType for the extension for the app to work on an iPod Touch, whereas with an extension of ".png" I could just put "image.png" in pathForResource and say ofType:nil. But all versions worked on the simulator.

The app bundle contains the image file, and I am using:

[[NSBundle mainBundle] pathForResource:@"Auto" ofType:@"jpg"]

to get a path.

Answer 5

Why don't you split the string that you get from the DB?

NSString* fullFileName = @"image.jpg";
NSString* fileName = [[fullFileName lastPathComponent] stringByDeletingPathExtension];
NSString* extension = [fullFileName pathExtension];

Now you can simply use:

[[NSBundle mainBundle] pathForResource:fileName ofType:extension]];
