建立一個 UIView

Objective-C

CGRect myFrame = CGRectMake(0, 0, 320, 35)
UIView *view = [[UIView alloc] initWithFrame:myFrame];

//Alternative way of defining the frame
UIView *view = [[UIView alloc] init];
CGRect myFrame = view.frame;
myFrame.size.width = 320;
myFrame.size.height = 35;
myFrame.origin.x = 0;
myFrame.origin.y = 0;
view.frame = myFrame;

迅速

let myFrame = CGRect(x: 0, y: 0, width: 320, height: 35)
let view = UIView(frame: myFrame)
