Xcode的代碼編輯器是可以進(jìn)行主題設(shè)置的继找，如果是白色背景一般會(huì)比較傷眼喘帚，所以都會(huì)修改一些主題。
在Xcode菜單欄中進(jìn)行偏好設(shè)置恨狈，可以設(shè)置Fonts&Colors，它會(huì)提供一些現(xiàn)有的主題介返，可以對(duì)現(xiàn)有的主題進(jìn)行顏色拴事、字體大小的設(shè)置：
image
也可以自行進(jìn)行設(shè)置沃斤，或者下載其他人設(shè)置好的主題文件，導(dǎo)入到Xcode中去刃宵。比如我這個(gè)主題：
image
主題文件都是xml寫的衡瓶，內(nèi)容在文末可以直接復(fù)制，新建一個(gè)文件命名為Monokai.dvtcolortheme牲证，將文末的xml內(nèi)容復(fù)制進(jìn)去就可以了哮针。
然后將這個(gè)主題文件放到Xcode的主題文件夾中，這個(gè)文件夾通過終端來打開比較方便坦袍，路徑是：~/Library/Developer/Xcode/UserData/FontAndColorThemes/
放進(jìn)去后重啟一下Xcode十厢，就可以在偏好設(shè)置中看到他了，選中就可以了捂齐，我習(xí)慣將所有文字大小都調(diào)成18蛮放，比較大，看起來對(duì)眼睛好一些奠宜，也可以把背景調(diào)成護(hù)眼色（色調(diào)：55包颁，飽和度：123，亮度：205压真，紅：199娩嚼，綠：237，藍(lán)：204）滴肿。
主題內(nèi)容：
