Question

I need to return an array but don’t know how to do this, here is how it looks

CGPoint position[] = {
    CGPointMake(500, 200),             
    CGPointMake(500, 200)                         
};

return position;

But I get an error of incompatible result. Any way around this error? Need to return multiple positions.

You can do something like this

NSArray *position = [NSArray arrayWithObjects:
                     [NSValue valueWithCGPoint:CGPointMake(500, 200)],
                     [NSValue valueWithCGPoint:CGPointMake(600, 300)],
                     nil];  

for getting the values from array

for(int i=0; i<[position count]; i++) {
    NSValue *value = [position objectAtIndex:i];
    CGPoint point = [value CGPointValue];
    NSLog(@"%@",NSStringFromCGPoint(point);
}
