NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, 
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:@"abc.txt"];
NSString *content = [NSString stringWithContentsOfFile:filePath     
encoding:NSUTF8StringEncoding error:NULL];

Answer 1

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, 
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSArray *directoryContent = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:nil];
NSString *fileWithExt = nil;
for (NSString *file in directoryContent )
{
    if([file stringByDeletingPathExtension] isEqualsTo:@"abc"]
    {
       fileWithExt = file;
       break;
    }
}

PS : The fileWithExt will contain the first file with name abc
