快速以编程方式添加不同数量的标签和滑块

Question

In swift and Xcode I want to be able to make an app where the user can enter what subjects they have, and then proceed to the next page, where they are greeted with a page where they can pick how much they like each subject as a percentage, using labels and sliders.

What I am unsure about is how I can add varying amounts of labels and sliders, depending on how many subjects they add.

eg if the user inputs Maths, English, and Science, on the next page, I will need to add exactly 3 labels and exactly 3 sliders programmatically.

If anyone could tell me how I would go about solving this problem I would much appreciate it :)

Answer 1

In the first page, where the user 'picks' the subject, add these subjects to an array object. The array object will then have a count.

On the second page, pass through the array of 'subject' object inside of an array. Then add a UITableView to the second page. Make a prototype UITableViewCell that contains a UILabel and a UISlider. Then on the UITableViewDelegate and Datasource, set the numRowsForSection to be the count of the array, and the table will draw that many cells. Then pass the subject data from the array to the cell with cellForRowAtIndexPath and continue from there.

If you are not familiar with UITableView and its delegate/datasources, look those up first!
