Sharesheet from a tableViewCell popover on the ipad
I'm trying to share something to the sharesheet from a button inside a cusom cell on a UITableView thats presented as a popover. I keep getting:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Application tried to present modal view controller on itself. Presenting controller is .
func passToShareSheet(fileName: String, ext: String, stringToWriteToFile: String){
let fileName = "(fileName).(ext)"
let path = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(fileName)
do {
try stringToWriteToFile.write(to: path!, atomically: true, encoding: String.Encoding.utf8)
let vc = UIActivityViewController(activityItems: [path as Any], applicationActivities: )
vc.popoverPresentationController?.sourceView = self
vc.present(vc, animated: true, completion: nil)
print(stringToWriteToFile)
} catch {
print("Failed to create file")
print("(error)")
}
}
I realize its because this is being called on a UITableViewCell but I have no idea how to do it the correct way? any help?
vc.present
theTableViewController.present
How do I get a reference to that from the cell?

May be you can set a weak reference of the tableVIewController to the UItableViewCell when you are loading the UItableVIewCell. Thus you can avoid retain cycle and at the same time can also present the view controller.

This code should be executed in your view controller, not in the cell. Use delegation or a closure to have the cell call code in the view controller

Try below code
using button action of custom cell.
@IBAction func tapOnShowShareSheet(_ sender:UIButton) {
let buttonposition = sender.convert(CGPoint.zero, to: tableview_name)
if let indexpath = tableview_name.indexPathForRow(at: buttonposition) {
let stringToWriteToFile = stringToWriteToFile_using_indexpath
let fileName = fileName_from_cell_using_indexpath
let ext = ext_from_cell_using_indexpath
let fileName = "(fileName).(ext)"
let path = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent(fileName)
do {
try stringToWriteToFile.write(to: path!, atomically: true, encoding: String.Encoding.utf8)
let vc = UIActivityViewController(activityItems: [path as Any], applicationActivities: )
vc.modalPresentationStyle = .popover
vc.popoverPresentationController?.sourceView = self
vc.popoverPresentationController?.sourceView = sender
vc.popoverPresentationController?.sourceRect = sender.bounds
self.present(vc, animated: true, completion: nil)
print(stringToWriteToFile)
} catch {
print("Failed to create file")
print("(error)")
}
}
}
This works only if
self is a view controller, which might not be the case– Crazyrems

self
@Crazyrems actually the popoverPresentationController Will present on ViewController but the permittedArrowDirections will be on Sender Button of Cell.

You need to change
vc.presenttotheTableViewController.present. But of course you don't have a reference to that view controller from the cell.– rmaddy
