版本为Swift2.3
- let imgCoupon = UIImageView()
- imgCoupon.frame = CGRectMake(0,0,16,16)
- imgCoupon.loadImgByNamed("coupon")
- imgCoupon.tag = 12345
- cell.addSubview(imgCoupon)
- imgCoupon.translatesAutoresizingMaskIntoConstraints = false
- let l = NSLayoutConstraint(item: imgCoupon,attribute: .Leading,relatedBy: .Equal,toItem: firstView,attribute: .Trailing,multiplier: 1,constant: 3)
- l.active = true
- let c = NSLayoutConstraint(item: imgCoupon,attribute: .CenterY,toItem: lbName,constant: 0)
- c.active = true
- let h = NSLayoutConstraint(item: imgCoupon,attribute: .Height,toItem: nil,attribute: .NotAnAttribute,constant: 16)
- h.active = true
-
- let w = NSLayoutConstraint(item: imgCoupon,attribute: .Width,constant: 16)
- w.active = true
Swfit2.3中使用w.active = true
而Swift3.0中是addConstraint(w),并且attribute的值也不同
