IOS UIView Setting rounded corners

UIView setting rounded corners

1, relatively simple situation, uiview Four Corners are rounded corner:

    UIView *aview = [[UIView alloc] init];        Aview.frame = CGRectMake (0, 0, +);    Aview.backgroundcolor = [Uicolor redcolor];        Set rounded border        AView.layer.cornerRadius = 8;        AView.layer.masksToBounds = YES;        Set border and border color        aView.layer.borderWidth = 8;        AView.layer.borderColor =[[Uicolor Graycolor] cgcolor];        [Self.view Addsubview:aview];

2. Set one or a few of the four corners as rounded corners

    UIView *aview = [[UIView alloc] init];        Aview.frame = CGRectMake (0, 0, +);    Aview.backgroundcolor = [Uicolor redcolor];        [Self.view Addsubview:aview];        Set the desired fillet position and size    uibezierpath *maskpath = [Uibezierpath bezierPathWithRoundedRect:aView.bounds byroundingcorners : Uirectcornerbottomleft | Uirectcornerbottomright Cornerradii:cgsizemake (Ten)];    Cashapelayer *masklayer = [[Cashapelayer alloc] init];    Masklayer.frame = aview.bounds;    Masklayer.path = Maskpath.cgpath;    AView.layer.mask = Masklayer;

Among them, Uirectcornerbottomleft,uirectcornerbottomright is the angle that can be selected.

typedef ns_options (Nsuinteger, Uirectcorner) {    Uirectcornertopleft     = 1 << 0,    Uirectcornertopright    = 1 << 1,    uirectcornerbottomleft  = 1 << 2,    Uirectcornerbottomright = 1 << 3,    uirectcornerallcorners  = ~0ul};

The above enumeration is a corner that you can choose from: Top left, top right, bottom left, bottom right, and so on.
