Hey Everybody,
If I wanted to store an object in a dictionary and set its key as the
object's memory address - how would I go about doing this?
Right now I'm doing this:
int i;
for (i = 0 ; i < 10 ; i++)
{
NSObject *myObject = [[NSObject alloc] init];
[dictionary setValue:myObject forKey:[NSString
stringWithFormat:@"%x",
&myObject]];
}
Use:
int i;
for (i=0;i<10;i++)
{
NSObject *myObject = [[NSObject alloc] init];
NSValue *val = [NSValue valueWithPointer:myObject];
[dictionary setValue:myObject forKey:val];
}
Or [NSNumber numberWithInt:(int)myObject] instead of the NSValue.
Actually now that I'm looking at this more closely, NSDictionary is
expecting an NSString for the key when inserting a value. Your
example uses an NSValue for the key - the compiler is throwing a
warning for this one..
