What is frame and bound view?

frame = a view’s location and size using the parent view’s coordinate system ( important for placing the view in the parent) bounds = a view’s location and size using its own coordinate system (important for placing the view’s content or subviews within itself)

What is frame in Uiview?

Frame A view’s frame ( CGRect ) is the position of its rectangle in the superview ‘s coordinate system. By default it starts at the top left. Bounds A view’s bounds ( CGRect ) expresses a view rectangle in its own coordinate system.

What does the frame do in Swift?

The frame has to do with where the view is situated(location) within the parent view, but also, something like a rotation will affect it too. The frame rectangle, which describes the view’s location and size in its superview’s coordinate system. Let’s talk about the location of the frame.

What is a views frame?

A view’s frame specifies the view’s size and its position relative to its superview. Because a view’s size is always specified by its frame, a view is always a rectangle. A CGRect contains the members origin and size.

What is the difference between frame and bounds in IOS?

11 Answers. 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). 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.

What is the difference between frames and bounds in Swift?

At its simplest, a view’s bounds refers to its coordinates relative to its own space (as if the rest of your view hierarchy didn’t exist), whereas its frame refers to its coordinates relative to its parent’s space.

What is the difference between frame and bound of a UIView?

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). 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.

Are bounds origin always zero?

The origins of a bounds is not always zero. Remember I said that the bounds origin is the origin of the view with respect to its own coordinate system, so in the majority of cases, the bounds origin is (0, 0) . A transform on the view’s coordinate system will affect its origin.

What is bound properties in IOS?

What happens to the the frame and bounds when performing a transform to the view?

Remember, the bounds is relative to the view’s own space, and internally to the view nothing has changed. If you transform the view, e.g. rotating it or scaling it up, the frame will change to reflect that, but the bounds still won’t – as far as the view is concerned internally, it hasn’t changed.

Is bounds origin always zero?

What is frame origin?

frame is the origin (top left corner) and size of the view in its super view’s coordinate system , this means that you translate the view in its super view by changing the frame origin , bounds on the other hand is the size and origin in its own coordinate system , so by default the bounds origin is (0,0).
