how to remove UITableView offset on the left in Swift

Question

I've found some questions and answers to remove offset of UITableViews in ios7, namely this one here How to fix UITableView separator on iOS 7?

I was wondering if anyone had come across the correct functions to remove inset margins. Something similar to this answer in objective-c

if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
    [tableView setSeparatorInset:UIEdgeInsetsZero];
}

Answer 1

You can just set the property: tableView.separatorInset = UIEdgeInsetsZero

Answer 2

Just like the Objective-C example, but converted to swift. I had some trouble myself. This code works in a UITableView if you were doing it in a UITableViewController you would substitute self.tableView for self:

// iOS 7
if(self.respondsToSelector(Selector("setSeparatorInset:"))){
    self.separatorInset = UIEdgeInsetsZero
}

// iOS 8
if(self.respondsToSelector(Selector("setLayoutMargins:"))){
    self.layoutMargins = UIEdgeInsetsZero;
}

And for the cell (iOS 8 only) put the code below in the following function:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath)

get the cell, and set the following property:

// iOS 8
if(cell.respondsToSelector(Selector("setLayoutMargins:"))){
    cell.layoutMargins = UIEdgeInsetsZero;
}

Answer 3

Put the following lines in viewDidLoad()

tableView.layoutMargins = UIEdgeInsetsZero
tableView.separatorInset = UIEdgeInsetsZero

Now look for your cellForRowAtIndexPath method and add this:

cell.layoutMargins = UIEdgeInsetsZero

nowadays ".zero" syntax...

    tableView.layoutMargins = UIEdgeInsets.zero
    tableView.separatorInset = UIEdgeInsets.zero

    cell.layoutMargins = UIEdgeInsets.zero

Answer 4

for Swift 3 just type:

tableView.separatorInset = .zero
