Scan from last instance of character to end of string using NSScanner
- by Virgil Disgr4ce
Given a string such as: "new/path - path/path/03 - filename.ext", how can I use NSScanner (or any other approach) to return the substring from the last "/" to the end of the string, i.e., "03 - filename.ext"? The code I've been trying to start with is:
while ([fileScanner isAtEnd] == NO){
slashPresent = [fileScanner scanUpToString:@"/" intoString:NULL];
if (slashPresent == YES) {
[fileScanner scanString:@"/" intoString:NULL];
lastPosition = [fileScanner scanLocation];
}
NSLog(@"fileScanner position: %d", [fileScanner scanLocation]);
NSLog(@"lastPosition: %d", lastPosition);
}
...and this results in a seg fault after scanning to the end of the string! I'm not sure why this isn't working. Ideas? Thanks in advance!
