將obj-c代碼翻譯成swift

Question

我需要將這個obj-c代碼翻譯成swift的幫助。我不知道我應該怎麼寫塊...

self.circularTimerView.frameBlock = ^(CircularTimerView *circularTimerView){ 
     circularTimerView.text = [NSString stringWithFormat:@"%f", [circularTimerView intervalLength]]; 
    }; 

太謝謝你了:)

你需要一個封閉的，而不是一個塊：

circularTimerView.frameBlock = { [unowned self] (circularTimerView:CircularTimerView) in 
    circularTimerView.text = NSString(format:"%f",circularTimerView.intervalLength()) 
}
