Compare part of a string in Obj C

I am trying to compare multiple strings. I have tried isEqual and caseSensitiveCompare but they only work if they match completely. I would like to compare a string and the start of another string.

ex string1 = @"hello"
string2 = @"he"

I would like compare these and get a positive result.

Looks like the method could be your solution. I found that in the NSString class documentation.

That worked. Thanks.
I used prefixWithString. I am new to programming and just getting used to finding the right methods in the documentation. I appreciate the help. Thanks again.
