Simple usage of Cgrectcontainspoint

Determine if CGRect contains a point that can be used with the Cgrectcontainspoint function

Cgrectcontainspoint See parameter description, whether a point is contained in a rectangle, so the parameter is a dot a rectangle

BOOL contains = cgrectcontainspoint(cgrect rect, cgpoint point);

Determines whether a cgrect is included in another cgrect, and whether it overlaps with the test given object

BOOL contains = cgrectcontainsrect(cgrect rect1, cgrect rect2);

cgrectintersectsrect

BOOL contains = cgrectintersectsrect(cgrect rect1, cgrect rect2);

float float_ = cgrectgetmaxx(cgrect rect); Returns the coordinates of the right edge of the rectangle

cgrectgetmaxy Returns the coordinates of the top of the rectangle

Cgrectgetmidx Returns the coordinates of the center x of the rectangle

Cgrectgetmidy Returns the coordinates of the center y of the rectangle

Cgrectgetminx Returns the coordinates of the left edge of the rectangle

Cgrectgetminy returns the coordinates at the bottom of the rectangle
