UIBezierPath bezierPathWithRoundedRect cornerRadius example in Objective C (iOS).

UIBezierPath bezierPathWithRoundedRect cornerRadius

Creates and returns a new UIBezierPath object initialized with a rounded rectangular path.

+ (UIBezierPath *)bezierPathWithRoundedRect:(CGRect)rect cornerRadius:(CGFloat)cornerRadius

Parameters
rect
The rectangle that defines the basic shape of the path
cornerRadius
The radius of each corner oval. A value of 0 results in a rectangle without rounded corners. Values larger than half the rectangle’s width or height are clamped appropriately to half the width or height.

Return Value
A new path object with the rounded rectangular path.

UIBezierPath bezierPathWithRoundedRect cornerRadius example.

CGRect outerRect = {0, 0, 200, 200};
CGRect innerRect  = CGRectInset(outerRect,  30, 30);

UIBezierPath *path = [UIBezierPath bezierPathWithRoundedRect:outerRect cornerRadius:10];

[path appendPath:[UIBezierPath bezierPathWithRoundedRect:innerRect cornerRadius:5]];
path.usesEvenOddFillRule = YES;

[[UIColor orangeColor] set];
[path fill];
