I have some calculation that involves negative values: row = (stagePosition - col) / PHNumRow; Say stagePosition is -7 and col is 1. They are both NSInteger, including row. PHNumRow is 8. If PHNumRow is NSInteger, I get the result I expect: -1. But if PHNumRow is NSUInteger, the result is garbage. Why should it matter if the divisor...

I am trying to retrieve my NSIndexSet by calling GetIndexes:MaxCount:IndexRange Here is my code const NSUInteger arrayCount = picturesArray.count; NSUInteger theIndexBuffer[arrayCount]; [picturesArray getIndexes:theIndexBuffer maxCount:arrayCount inIndexRange:nil]; However, in the ...
I was wondering what is the rationale behind different styles of enum declaration on cocoa?

I have the following code: NSUInteger one = 1; CGPoint p = CGPointMake(-one, -one); NSLog(@"%@", NSStringFromCGPoint(p)); Its output: {4.29497e+09, 4.29497e+09} On the other hand: NSUInteger one = 1; NSLog(@"%i", -one); // prints -1 I know there’s probably some kind of overflow going on, but why do the two cases differ and why d...
