UIAutoAdaptKit

• 根据iOS设备屏幕尺寸比例计算调整
• 支持横竖屏屏幕适配
• 支持cocoapods : pod 'UIAutoAdaptKit'
  github链接 : https://github.com/Xianlau/UIAutoAdaptKit

一个能适配所有iphone和ipad的UI布局工具

• 结合 SnapKit 或者 frame 布局使用, 就能一套UI代码适配所有iOS设备.

     - autoWidth() : 两个view之间的宽度距离
     - autoHeight() : 两个view件之间的高度距离
     - autoLength() : 单个view之间的边长 (单个view的宽和高都必须使用这个,会自动适配)
  

• frame 布局:

        testView.frame = CGRect.init(x: autoWidth(20), y: autoHeihgt(20), width: autoLength(100), height: autoLength(100))

• SnapKit 布局:

        testButton.snp.makeConstraints { (make) in
            make.bottom.equalTo(-autoheight(50))
            make.centerX.equalToSuperview()
            make.width.equalTo(autoLength(100))
            make.height.equalTo(autoLength(30))
        }
