You should be able to figure it out by modifying my code here which adds tildes
or hashes. This is in a category of NSString.
- (NSString*)pathSuffixedWithString:(NSString*)suffix {
NSString* newPath = self ;
do {
newPath = [[[newPath stringByDeletingPathExtension]
stringByAppendingString:suffix]
stringByAppendingPathExtension:[self pathExtension]] ;
} while ([[NSFileManager defaultManager] fileExistsAtPath:newPath]) ;
return newPath ;
}
- (NSString*)tildefiedPath {
return [self pathSuffixedWithString:@"~"] ;
}
- (NSString*)hashifiedPath {
return [self pathSuffixedWithString:@"#"] ;
}
