我們寫(xiě)代碼時(shí)候，經(jīng)常會(huì)用到彈框，然后到處都是寫(xiě)基本一樣的代碼，干脆給它做一個(gè)分類(lèi)，封裝起來(lái)，這樣，直接調(diào)用方法。我這里僅僅提供了四種最常見(jiàn)的。使用方法非常簡(jiǎn)單，直接將UIViewController+Message 這個(gè)類(lèi)拖入到項(xiàng)目中，導(dǎo)入頭文件需要使用的地方，建議以后直接放pch

第一種：彈出UIAlertController 風(fēng)格為 UIAlertControllerStyleAlert 且有取消和確定按鈕

第二種：彈出UIAlertController 風(fēng)格為UIAlertControllerStyleAlert 并且只有一個(gè)確定按鈕

第三種：彈出UIAlertController 風(fēng)格為UIAlertControllerStyleActionSheet并且有兩個(gè)選擇項(xiàng)和一個(gè)取消項(xiàng)
