为什么我的UISegmentedControl的高度比它的高度约束大一个点？

Question

正如您在此屏幕截图中看到的，我为UISegmentedControl的高度添加了约束，但它总是比UISegmentedControl的高度小一点。知道为什么吗？

您已从# Example of custom encoder class CustomJsonEncoder(json.JSONEncoder): def default(self, o): # Here you can serialize your object depending of its type # or you can define a method in your class which serializes the object if isinstance(o, (Employee, Autocar)): return o.__dict__ # Or another method to serialize it else: return json.JSONEncoder.encode(self, o) # Usage json.dumps(items, cls=CustomJsonEncoder) 更改为Frame Rectangle

框架矩形取原框架。和对齐矩形采用布局框架。
