Swift使用OC的位移枚举的话可以像写数组一样
例如
typedef NS_OPTIONS(NSUInteger, QMUIViewBorderPosition) {
QMUIViewBorderPositionNone = 0,
QMUIViewBorderPositionTop = 1 << 0,
QMUIViewBorderPositionLeft = 1 << 1,
QMUIViewBorderPositionBottom = 1 << 2,
QMUIViewBorderPositionRight = 1 << 3
};
item.qmui_borderPosition = [.left, .top]
