This Post is to tell about the BOUND and FRAME in ios.

BOUND:

The bounds property of a view defines the size of the view and its position in the view's own coordinate system. This means that in most cases the origin of the bounds of a view are set to {0,0}. The view's bounds is important for drawing the view.

FRAME:

The frame of a view is a structure, a CGRect, that defines the size of the view and its position in the view's superview, the superview's coordinate system.

BELOW EXAMPLE WILL MAKE THE DIFFERENCE MORE CLEAR

Imagine a view that has a size of 100x100 (width x height) positioned at 25,25 (x,y) of its superview. The following code prints out this view's bounds and frame: // This method is in the view controller of the superview

- (void)viewDidLoad
{
[super viewDidLoad];

NSLog(@"bounds.origin.x: %f", label.bounds.origin.x);
NSLog(@"bounds.origin.y: %f", label.bounds.origin.y);
NSLog(@"bounds.size.width: %f", label.bounds.size.width);
NSLog(@"bounds.size.height: %f", label.bounds.size.height);

NSLog(@"frame.origin.x: %f", label.frame.origin.x);
NSLog(@"frame.origin.y: %f", label.frame.origin.y);
NSLog(@"frame.size.width: %f", label.frame.size.width);
NSLog(@"frame.size.height: %f", label.frame.size.height);

}

And the output of this code is:

bounds.origin.x: 0
bounds.origin.y: 0
bounds.size.width: 100
bounds.size.height: 100

frame.origin.x: 25
frame.origin.y: 25
frame.size.width: 100
frame.size.height: 100
