[ACCEPTED]-How do I create a CGRect from a CGPoint and CGSize?-cgrectmake
Accepted answer
Two different options for Objective-C:
CGRect aRect = CGRectMake(aPoint.x, aPoint.y, aSize.width, aSize.height);
CGRect aRect = { aPoint, aSize };
Swift 1 3:
let aRect = CGRect(origin: aPoint, size: aSize)
Building on the most excellent answer from 3 @Jim, one can also construct a CGPoint and 2 a CGSize using this method. So these are 1 also valid ways to make a CGRect:
CGRect aRect = { {aPoint.x, aPoint.y}, aSize };
CGrect aRect = { aPoint, {aSize.width, aSize.height} };
CGRect aRect = { {aPoint.x, aPoint.y}, {aSize.width, aSize.height} };
CGRectMake(yourPoint.x, yourPoint.y, yourSize.width, yourSize.height);

you can use some sugar syntax. For example:
This 2 is something like construction block you 1 can use for more readable code:
CGRect rect = ({
CGRect customCreationRect
//make some calculations for each dimention
customCreationRect.origin.x = CGRectGetMidX(yourFrame);
customCreationRect.origin.y = CGRectGetMaxY(someOtherFrame);
customCreationRect.size.width = CGRectGetHeight(yetAnotherFrame);
customCreationRect.size.height = 400;
//By just me some variable in the end this line will
//be assigned to the rect va
customCreationRect;
)}
