nsarray

Maybe I'm doing something wrong and my approach is bad altogether. I know I could create a new class and have 2 properties (title, desc), but is there a way without creating a class

Here's my code snippet for this, NSPredicate *predicate = [NSPredicate predicateWithFormat:@"Date >= %@ AND Date <= %@", startDate,endDate]; NSArray *filter = [arrayEvents filteredArrayUsingPredicate:predicate]; Test filtration : Case 1: NSString *startDate = @"01/07/14"; NSString *endDate = @"31/07/2014"; Output: All events (rows). Case 2: NSString

For example, I read a data like this a\tbcd\tttte\tjjjd\tnjnjnjd\tss\tee and I want to make a array like this: { @"a", @"bcd", @"ttte", @"jjjd", @"njnjnjd", @"ss", @"ee" } How can I do so? Thank you.

Are there any advantages/disadvantages to storing either an NSArray or an NSDictionary ? Also, are there any rules with regards to what you can or can't store in a plist?
