Question

I am making an nsmutable array by separating a string by component it is causing a lot of new line and white spaces to be inserted in the array how to identify and remove them?

for (int i=0;i<contentsOfFile.count; i++) 
 {
        if(!([[contentsOfFile objectAtIndex:i]isEqual:@"\n"]||[[contentsOfFile     objectAtIndex:i]isEqual:@""]))
       [arrayToBereturned addObject:[contentsOfFile objectAtIndex:i]];
 }

this code which i am using cannot identify all new line charectors
thanks

If you want an array without whitespace:

NSString *string = @"Hello, World!";
NSCharacterSet *separator = [NSCharacterSet whitespaceAndNewlineCharacterSet];
NSArray *stringComponents = [string componentsSeparatedByCharactersInSet:separator];
