1 , Frame The frame of an UIView is the rectangle , expressed as a location (x,y) and size (width, height) relative to the superview it is contained within. In short , a view's location and size using the parent view's coordinate system 2 , Bounds The bounds of an UIView is the rectangle , expressed as a location (x,y) and size (width, height) relative to its own coordinate system (0,0). In short , a view's location and size using its own coordinate system Example: Frame origin = ( 40 , 60 ) width = 80 height = 130 Bounds origin = ( 0 , 0 ) width = 80 height = 130 Thanks for reading, Happy Coding 👨💻
