問題：
I have discovered that I can create UILabel much faster than UITextField and I plan to use UILabel most of the time for my data display app.我發現創建 UILabel 的速度比 UITextField 快得多，而且我計劃大部分時間將 UILabel 用於我的數據顯示應用程序。
To make a long story short though, I wish to let the user tap on a UILabel and have my callback respond to that.長話短說，我希望讓用戶點擊 UILabel 並讓我的回調響應。 Is that possible?那可能嗎？
Thanks.謝謝。
