SwiftでObjective-Cのインスタンス生成メソッドobjectWithXXXの置き換え

More than 5 years have passed since last update.

内容

Objective-Cでインスタンスを生成するobjectWithXXXのようなクラスメソッドはSwiftだとClass(XXX:XXX)となる。
これは自作クラスでも適用される模様。

NSDateの例

NSDatedateWithTimeIntervalSince1970:の場合、それぞれ以下のようなコードになる。

Objective-C
NSDate * date = [NSDate dateWithTimeIntervalSince1970:0];
Swift
let date:NSDate = NSDate(timeIntervalSince1970:0)

自作クラスの例

Objective-Cで自作したクラスのクラスメソッドでも同様の対応は行われる。
TestClass+(TestClass*)testClassWithData:(TestData*)dataを用意すると以下のようになる。

Objective-C
TestClass * test = [TestClass testClassWithData:data];
Swift
let test:TestClass = TestClass(data:data)
