iOS / objective-c：将对象传递给新的视图控制器

I am launching a modal view controller in code and wish to pass along a data object. I have created a property on the destination VC for the object. The new VC is launching fine but not getting the data object. Is there anything wrong with the following code? If not, I will have to look for error somewhere else but wondering if this is right way to pass data object.I am launching a modal view controller in code
