IOS Authoring Table (data source control row, number of columns)

　Remember the interview process last year, an interviewer asked me how to make a form. Because have not done before, at that time a bit of a confused force, today think up, and use TableView made a, hope not someone like me drop pit,

directly on the code :

Because the table is generally the overall scrolling, it closed the tableview rolling, put TableView on the Uiscrollview, but feel this will affect the efficiency of operation, time to optimize it,

Do you have any good advice for me to say, thank you
