iOS Bezier Curve Method explained

1, according to a rectangular drawing curve

+ (Uibezierpath *) Bezierpathwithrect: (cgrect) rect

2, according to the rectangular frame of the inscribed circle Draw curve

+ (Uibezierpath *) Bezierpathwithovalinrect: (cgrect) rect

3, according to the curve of the rectangular drawing with rounded corners

+ (Uibezierpath *) Bezierpathwithroundedrect: (cgrect) Rect Cornerradius: (cgfloat) Cornerradius

4, in the rectangle, you can have a corner in the corners of the fillet, generally used to set a view of the top two corners of the circle

+ (Uibezierpath *) Bezierpathwithroundedrect: (cgrect) rect byroundingcorners: (uirectcorner) Corners cornerRadii: ( Cgsize) cornerradii

Parameters:

Corners: Enumeration value, you can select a corner

Cornerradii: size of rounded corners

5. Draw an arc with a center point + (Uibezierpath *) Bezierpathwitharccenter: (cgpoint) Center radius: (cgfloat) Radius startangle: (cgfloat ) startangle Endangle: (cgfloat) endangle clockwise: (BOOL) clockwise;

Parameters:

Center: The coordinates of the ARC's central point

Radius: radius of the circle in which the arc is located

StartAngle: The angle value at which the arc starts

Endangle: Angle value for arc end

Clockwise: Whether to draw an arc clockwise

6, draw two Yuan curve, general and movetopoint with use

-(void) Addquadcurvetopoint: (cgpoint) endPoint controlpoint: (cgpoint) ControlPoint

Parameters:

EndPoint: The end of the curve

ControlPoint: Drawing a datum point of a curve

7, with three points to draw a curve, general and movetopoint with the use of

-(void) Addcurvetopoint: (cgpoint) endPoint controlPoint1: (cgpoint) controlPoint1 ControlPoint2: (cgpoint) ControlPoint2

Parameters:

EndPoint: The end of the curve
