Several ways to cut corners in iOS

These days in the study to the fillet of the method, also found the next online information----------

Cut corners to avoid off-screen rendering as much as possible.

1. Setting fillets directly with the two properties in a layer in the view is simple, but not recommended for performance:

@property (Strong, nonatomic) Iboutlet Uiimageview *imageview;

Self.imageView.layer.cornerRadius = 5;

Self.imageView.layer.masksToBounds = YES;

2. Set the fillet through layer and Bezierpath

-(void) Setlayerandbezierpathcutcircularwithview: (UIView *) view

{

Create Bezierpath and set corners and radii

Uibezierpath *path = [Uibezierpath bezierPathWithRoundedRect:view.bounds byroundingcorners:uirectcornertopleft | Uirectcornertopright| Uirectcornerbottomleft| Uirectcornerbottomright Cornerradii:cgsizemake (5, 5)];

Cashapelayer *layer = [[Cashapelayer alloc] init];

Layer.frame = View.bounds;

Layer.path = path. Cgpath;

View.layer.mask = layer;

}

3. Set the fillet with the graphics and Bezierpath

-(void) Setgraphicscutcirculaywithview: (Uiimageview *) view

{

Uigraphicsbeginimagecontextwithoptions (View.bounds.size, NO, 1.0);

[[Uibezierpath BezierPathWithRoundedRect:view.bounds cornerradius:5] addclip];

[View DrawRect:view.bounds];

View.image = Uigraphicsgetimagefromcurrentimagecontext ();

End

Uigraphicsendimagecontext ();

}
