Question

I have an NSString that contains some values separated by an unknown number of whitespace characters. For example:

NSString* line = @"1 2     3";

I would like to split the NSString into an NSArray of values like so: {@"1", @"2", @"3"}.

Answer 1

Get the components separated by @" " and remove all objects like @"" from the resultant array.

NSString* line = @"1 2     3";
NSMutableArray *array = (NSMutableArray *)[line componentsSeparatedByString:@" "];
[array removeObject:@""]; // This removes all objects like @""
