Sweep a string and insert portions into an array

Question

I have this string, inside the variable 'strings':

NSMutableArray *array_strings;
NSString *strings = @"one<-+->two<-+->three";

The separator string is "<-+->". I want to place certain words from the string within an array, as below:

• [0] -> one
• [1] -> two
• [3] -> three

Answer 1

Try:

array_strings = [[string componentsSeparatedByString:@"<-+->"] mutableCopy];

Notes:

1. array_strings should really be named arrayStrings
2. strings should generally be named as a singular, not plural (plural would be used for collections)
3. Scan the methods on a class to see what's readily available ;-)
