How to add array to a TableViewController? - ios

Question

While I was surfing over the Internet I've found a lot of examples how to load array in the TableViewController, but none of them helped me!
Couldn't you help me to find what is wrong in my code ?
Thank you in advance!!!

Answer 1

well 1) numberOfSections is 0. to see something it should be one IIRC
think thats it but havent double checked

Answer 2

Assuming your data array is built up correctly, your mistake in is your numberOfSections methods. Currently, it returns 0, which tells the UITableView that there are currently no sections to be displayed… ever.
You can either return 1; there or remove the entire method altogether. The default implementation, which you inherit from UITableViewController, also returns 1 by default.
My advice would be to remove the method, as that keeps your own code cleaner. You can always implement it in a later stage, when you might actually need it.
