Recently i was making an NSMutableArray from a string by separating the string by component, Unfortunately it was filling too many empty useless elements into my array…in order to remove them i used following code
for (int i=0;i<contentsOfFile.count; i++)
{
if(!([[contentsOfFile objectAtIndex:i]isEqual:@”n”]||[[contentsOfFile objectAtIndex:i]isEqual:@””]||[[contentsOfFile objectAtIndex:i]isEqual:@”rn”]))
[arrayToBereturned addObject:[contentsOfFile objectAtIndex:i]];
}
i added only those object which were relevant to an array and returned it
