Get the List Of Specified File Types (png, xml, etc) In Any Folder In iOS

Here we are going to show how you can get a list of file types using the NSPredicate object.

For example, let's you need a list of all the PNG files available in your application bundle, then

NSString *bundlePath = [[NSBundle mainBundle] bundlePath];
 
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *bundleDirectory = [fileManager contentsOfDirectoryAtPath:bundlePath error:nil];
 
NSPredicate *filter = [NSPredicate predicateWithFormat:@"self ENDSWITH '.png'"];
NSArray *pngFiles = [bundleDirectory filteredArrayUsingPredicate:filter];
 
NSLog(@"PNG files: %@", pngFiles);

Here the output is like,

2012-06-18 12:36:16.869 Sandbox[23412:13a03] PNG files: (
"default.png",
"photo1.png",
"photo2.png",
"myImage.png"
)

You can change the path and filter as needed to list files of any type and in any folder.
