Title: RE: checking if a string is with in a different string
The method you want isn't immediately obvious by name, but its in the 'Substrings' section of the NSString docs. You want to use one of these...
[myString rangeOfString:subString];
[myString rangeOfString:subString options:];
[myString rangeOfString:subString options: range:];
Returns an NSRange, with a location of NSNotFound if 'subString' isn't a substring of 'myString'.
Hope that helped!

Subject: checking if a string is with in a different string
Sorry thats worded badly but i couldn't think of how else to put it,
anyways. I have recently moved from RB, as stated in previous posts of
mine, and i'm still trying to get to grips with it all, but i must say
i am getting there, thankfully.
I'm creating a search function for my program, and in RB i would of
used the InStr function to check if a string occured in side another
string for example
searchString :World
string :Hello World
Found :YES
like i said i would of done
if instr(String,SearchString)>0 Then
//It was found
else
//not found
end if
In Obj-C i have tried to do this:
if ([string compare:searchString] == NSNotFound){
//Not Found
}else{
//Found
}
but it has not worked, could anyone help me out and tell where i'm
going wrong?
