目标C
CGRect myFrame = CGRectMake(0, 0, 320, 35) UIView *view = [[UIView alloc] initWithFrame:myFrame]; //定义框架的另一种方法 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)
