// SPAlertControllerStyleActionSheet样式下：默认为UILayoutConstraintAxisVertical(垂直排列),
如果设置为UILayoutConstraintAxisHorizontal(水平排列)，则除去取消样式action之外的其余action将水平排列；
SPAlertControllerStyleAlert样式下：当actions的个数大于2，或者某个action的title显示不全时
为UILayoutConstraintAxisVertical(垂直排列)，
否则默认为UILayoutConstraintAxisHorizontal(水平排列)，此样式下设置该属性可以修改所有action的排列方式；
不论哪种样式，只要外界设置了该属性，永远以外界设置的优先

// 该属性配置的是距离屏幕边缘的最小间距；SPAlertControllerStyleAlert样式下该属性是指
对话框四边与屏幕边缘之间的距离，此样式下默认值随设备变化，SPAlertControllerStyleActionSheet
样式下是指弹出边的对立边与屏幕之间的距离，比如如果从右边弹出，
那么该属性指的就是对话框左边与屏幕之间的距离，此样式下默认值为70

// SPAlertControllerStyleAlert下的偏移量配置 ,CGPoint类型，y值为正向下偏移，
为负向上偏移；x值为正向右偏移，为负向左偏移，该属性只对SPAlertControllerStyleAlert样式有效,
键盘的frame改变会自动偏移，如果外界手动设置偏移只会取手动设置的
