Problem with substring from NSArray

[garyshaf]

Hi everyone,

I can't seem to figure out how to get a substring from an array element to a different string:

I have the following NSArray:

"image1.png|Description for image"
"image2.png|Description for image"
"image3.png|Description for image"

I already have the image name in a for loop but can't get the descpription where it matches the image name in the array.

NSString *imageDesc = nil;

NSString *positionsPath = [[NSBundle mainBundle]  pathForResource:@"position_descriptions" ofType:@"txt" inDirectory:@"/"];
	NSArray *positionsDesc = [[NSString stringWithContentsOfFile:positionsPath encoding:NSUTF8StringEncoding error:nil] componentsSeparatedByString:@"\n"];
	
...
...
...

UIImage *image = [UIImage imageNamed:imageName];
		imageView = [[UIImageView alloc] initWithImage:image];

I'd like to get the corresponding imageDesc from NSArray where it's equal to the imageName.

Any help would greatly be appreciated.

Thanks!
