Hi.
I have class MyDot. This class has function:
- (BOOL) containsPoint: (NSPoint) pt;
I have also NSArray, which contains several MyDot objects:
NSArray* dots;
I want to get new array
NSArray* newDots
which contains MyDot objects and
for these dots containsPoint:(NSPoint)pt = YES.
How can I do that?
I would like to write something like that:
NSPoint checkedPoint = NSMakePoint(100, 100);
NSPredicate* predicate = [NSPredicate predicateWithFormat:
@"containsPoint %p == YES ", checkedPoint]; //i don't know what to
write here
NSArray* newDots = [dots filteredArrayUsingPredicate: predicate];
I would be glad if you helped me.
