How to set Frame properly in Viewdidappear using reference of cell

Question

I want to display captured video using MPMoviePlayer for that purpose I designed one customcell and number of sections is one and I am loading ten by ten records in tableView so number of rows depends on array count so every time ten by ten records displaying from getService and my problem is frame is not setting properly in cell for that purpose I wrote entire code in one method and called that method in viewDidAppear() and when getting cell reference in viewDidAppear() getting fatal error in NSIndexPath I am thinking that viewDidAppear() is calling before I am getting cell reference so how to solve this problem please tell me any solution?

Answer 1

You are not supposed to manipulate with frames of cells from viewDidAppear of your view controller.

A frame consists of: left, top, width, and height.

• left is always 0;
• top is specified by a table and is based on the index path and heights of previous cells, section headers, and a table's header;
• width is always equal to a width of the table;
• height you can specify by yourself by overriding UITableViewDelegate's method optional func tableView(_ tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat

But most likely you are interested in a different thing. And you want to layout UI elements within you cells. If yes, you have a few ways to do this:

• Override func layoutSubviews() method in the cell and set all frames you want. This method is called every time when frame is changed. So it's exactly what you need.
• Also you can specify the desired layout using auto layouts. This may be done in a storyboard/xib file or in code (in a designated constructor of the cell).
