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'

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))
}
