在項(xiàng)目中合理的使用一些宏忙上，可以很大的提高代碼效率，代碼簡(jiǎn)潔度闲坎！下面我就列舉一些我常用的宏疫粥，隨著項(xiàng)目的進(jìn)行茬斧，我會(huì)持續(xù)更新！
在這里呢梗逮，我一般是把常用宏分類寫(xiě)：基礎(chǔ)宏项秉，顏色宏，地址宏库糠，通知文字等常量

在iPhone x以后蘋(píng)果新推出劉海屏機(jī)型涮毫，蘋(píng)果的各機(jī)型狀態(tài)欄高度均為44瞬欧。
但是今年蘋(píng)果隨著蘋(píng)果新操作系統(tǒng)iOS 14的推出導(dǎo)致了iPhone x以后的部分蘋(píng)果劉海屏機(jī)型狀態(tài)欄的高度的改變有的為47，有的為48罢防，有的還是44艘虎。
目前這個(gè)更改不知道是ios 14.2的bug，還是說(shuō)以后蘋(píng)果會(huì)把劉海屏機(jī)型的狀態(tài)欄的高度依然全部改成44咒吐。
