appropriate position and size, so when the constraints imposed on a uiview can uniquely determine its frame (x, y, Width, Height), the use of our automatic layout is correct. The two types of mistakes that novices usually make are constraints (too few constraints) and constraint conflicts (too many constraints). If you give a constraint that only determines the size of the view, or if there is an item (such as x) in the position or position, there will be insufficient constraints, and in Xib or

In this case, it is still difficult to get rid of the judgment and reliance on the equipment, and then, if there are new sizes and device
