How to get strings with specific length from NSArray?

Question

I want to get strings that have specific length in NSArray.

The array has many elements and I don't want to use fast enumeration.

Is there a possible way?

Answer 1

This works like a charm:

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"self.length == %d", lenght];
NSArray *filtered = [array filteredArrayUsingPredicate:predicate];

Answer 2

No matter what you do you will be using fast enumeration whether you realize it or not. However, have you considered using an NSPredicate object and the filteredArrayWithPredicate method?

Answer 3

NSArray *yourArray = [[NSArray alloc] initWithObjects:@"Apple, Orange, Grapes, Cherry, nil"];

for(NSString *element in yourArray){

    if(element.length==yourLength){
        [filteredArray addObject:element];
    }
}

NSLog(@"Filtered array now contains the elements with length %d", yourLength);
NSLog(@"Filtered array--%@", filteredArray);
