這是因?yàn)槟愕膙iewcontroller 繼承了UIViewController.而UIViewController 繼承自oc的NSObject. 在swift 中被修飾成@objc class. 那么就必須要遵循oc的selector，在oc中是不支持方法重載的。所以會(huì)報(bào)上面的錯(cuò)誤
如果要解決這種問(wèn)題有兩種方法
1. 刪除繼承自oc的類
2. 其中一個(gè)方法重命名
你的這種情況，顯然第一種方法不合適，你的控制器還是需要繼承自u(píng)iviewcontroller，那么只能用第二種方法，對(duì)這個(gè)方法進(jìn)行重命名。
參考：
其實(shí)就是想知道怎么開(kāi)發(fā)ios的app吧?
首先, 不要倔強(qiáng), 你需要付出99$購(gòu)買開(kāi)發(fā)者賬號(hào), 需要一臺(tái)測(cè)試用的iphone/ipad, 最好有一臺(tái)mac電腦.
然后, 你會(huì)購(gòu)買賬號(hào)之后, 那個(gè)買賬號(hào)的網(wǎng)站會(huì)把這些問(wèn)題的答案全部告訴你.
最后, 你問(wèn)題比較多, 就不詳細(xì)描述了, 有耐心的話, 那個(gè)網(wǎng)站會(huì)把所有的告訴你
首先我們要打開(kāi)手機(jī)，然后從iPhone手機(jī)的底部向上滑動(dòng)，調(diào)出“控制中心”頁(yè)面，然后點(diǎn)擊右上方的“轉(zhuǎn)屏”按鈕，關(guān)閉“豎排方向鎖定”。
iPhone手機(jī)調(diào)用科學(xué)計(jì)算器
第二步：這時(shí)我們的手機(jī)就可以橫豎自由旋轉(zhuǎn)了，接下來(lái)在“附加程序”中找到“計(jì)算器”并打開(kāi)，這時(shí)我們看到的還是簡(jiǎn)單的計(jì)算器。
iPhone手機(jī)調(diào)用科學(xué)計(jì)算器
第三步：之后我們只要旋轉(zhuǎn)手機(jī)，讓手機(jī)由豎向轉(zhuǎn)為橫向，計(jì)算器就可以變?yōu)椤翱茖W(xué)計(jì)算器”的界面了，這時(shí)用戶就可以算那些復(fù)雜的數(shù)據(jù)了。
