任何人都可以帮助我我有这个简单的视图,如果我正在使用故事板但我的所有UILabel都基于某个地方(API),这就是我需要以编程方式创建视图的原因。
这是我想要实现的观点
我目前所取得的成就是将顶部标签固定在其位置,并在标签1,2和&处添加前导空间。 3
基本上我需要的是:到目前为止,这是我的代码。
private func addTopConstraint(from:AnyObject,to:AnyObject,cons:CGFloat){
let topConstraint = NSLayoutConstraint(item: from, attribute: .Top, relatedBy: .Equal, toItem: to, attribute: .Bottom, multiplier: 1.0, constant: cons)
self.view.addConstraint(topConstraint)
}
private func addVerticalSpace(from:AnyObject,to:AnyObject,cons:CGFloat){
let verticalSpace = NSLayoutConstraint(item: from, attribute: .Bottom, relatedBy: .Equal, toItem: to, attribute: .Bottom, multiplier: 1.0, constant: cons)
self.view.addConstraint(verticalSpace)
}
private func addLeadingSpace(from:AnyObject,to:AnyObject,cons:CGFloat){
let leadingSpace = NSLayoutConstraint(item: from, attribute: .Leading, relatedBy: .Equal, toItem: to, attribute: .Leading, multiplier: 1.0, constant: cons)
self.view.addConstraint(leadingSpace)
}
private func sameWidthAndHeight (from:AnyObject,to:AnyObject){
let width = NSLayoutConstraint(item: from, attribute: .Width, relatedBy: .Equal, toItem: to, attribute: .Width, multiplier: 1.0, constant: 0)
let height = NSLayoutConstraint(item: from, attribute: .Height, relatedBy: .Equal, toItem: to, attribute: .Height, multiplier: 1.0, constant: 0)
self.view.addConstraint(width)
self.view.addConstraint(height)
}
但sameWidthAndHeight
和addVerticalSpace
功能失败
谁能分享想法?提前致谢
