Question

What is the simplest way to split an NSString by the maximum number of characters?

For example, if I have a string that is 204 characters long and I want to split it at 100 characters, it should yield an NSArray with three substrings (100,100,4).

Answer 1

NSMutableArray *array = [[NSMutableArray alloc] init];
int len=0;

while( (len+100)<[string length]) {
    [array addObject:[string substringWithRange:NSMakeRange(len,100)]];
    len+=100;
}

[array addObject:[string substringFromIndex:len]];

Don’t forget to release the array when you have done.
