swift UITableView set rowHeight

Question

I am trying to set the height of each row in the tableView to the height of the corresponding cell with this code:

override func tableView(tableView: UITableView!, heightForRowAtIndexPath indexPath: NSIndexPath!) -> CGFloat {       var cell = tableView.cellForRowAtIndexPath(indexPath)       return cell.frame.height } 

I get this error when initialising var cell :

Thread 1:EXC_BAD_ACCESS(code=2,address=0x306d2c)

Answer 1

For setting row height there is separate method:

For Swift 3

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {     return 100.0;//Choose your custom row height } 

Older Swift uses

func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {     return 100.0;//Choose your custom row height } 

Otherwise you can set row height using:

self.tableView.rowHeight = 44.0 

In ViewDidLoad.

Answer 2

Put the default rowHeight in viewDidLoad or awakeFromNib. As pointed out by Martin R., you cannot call cellForRowAtIndexPath from heightForRowAtIndexPath

self.tableView.rowHeight = 44.0
