如何将此VB.net/C#代码移植到Objective-C / iOS？

Question

I need to do this in Objective-C / iOS:

Math.Round(h, MidpointRounding.AwayFromZero)

I know we have a round() function, but how about that "AwayFromZero" option? What is the equivalent to use?

Answer 1

是细胞

ceil(h)

Answer 2

Is there a ceil / ceiling function in Objective-C / iOS? It would have the same effect as your vb/c# code.
