Answer 1

Checkout this library

https://github.com/BadChoice/Collection

It comes with lots of easy array functions to never write a loop again

So you can just do

NSArray* result = [thArray filter:^BOOL(NSString *text) {
    return [[name substr:0] isEqualToString:@"A"]; 
}] sort];

This gets only the texts that start with A sorted alphabetically

If you are doing it with objects:

NSArray* result = [thArray filter:^BOOL(AnObject *object) {
    return [[object.name substr:0] isEqualToString:@"A"]; 
}] sort:@"name"];
