Xcode快捷鍵:
格式化代碼:
control + i (Editor-Structure-Re indent)
移動(dòng)代碼:
alt+command+[ (Editor-Structure-Move Line Up)
alt+command+] (Editor-Structure-Move Line Down)
從當(dāng)前位置刪除到分隔符:
例如: 如下代碼, 我們想把dataArray改為resultArray:
let group = dataArray[section]
通常做法是將鼠標(biāo)放到data后面, 然后按delete多次刪除data, 其實(shí)刪除的這一步可以按住alt+delete; 這樣就會(huì)刪除當(dāng)前鼠標(biāo)指針到前面分隔符之間的字符.
向后刪除:
fn + delete; 只是Mac系統(tǒng)的功能, 也就是說(shuō), 所有的編輯界面都可以用, 不僅限于Xcode
創(chuàng)建橋接文件:
因?yàn)槟壳癚MUI還沒(méi)有Swift版本, 是OC版本, 而我們是Swift項(xiàng)目, 所有需要?jiǎng)?chuàng)建橋接文件, 方法是在項(xiàng)目里面創(chuàng)建一個(gè)OC文件, 會(huì)自動(dòng)彈出提示詢問(wèn)是否添加橋接文件, 選擇是就行了
