Q:

Is there any way to change "DELETE" button from UITableViewCell?

I want to change DELETE button in UITableViewCell. 
Actually, I need to :

Change position of button 
font 
text color of that button.

Here I can only change button text in following delegate method :
- (NSArray<UITableViewRowAction *> *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath  
{  
    UITableViewRowAction *viewAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"Follow" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {  

        NSLog(@"View Action fired");  
    }];  
    viewAction.backgroundColor = [UIColor clearColor];  

    return @[callAction];  
}  

But how to change other attributes of button. If anyone knows, please let me know.
Thanks.

A:

To get this working, implement the following two methods on your UITableView's delegate to get the desired effect
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
    return YES;
}

 - (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
// you need to implement this method too esle nothing will work:

}

check your method you created the name of UITableViewRowAction *viewAction but you returned teh value of callAction modify once and try
- (NSArray<UITableViewRowAction *> *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath  
{  
    UITableViewRowAction *callAction = [UITableViewRowAction rowActionWithStyle:UITableViewRowActionStyleDefault title:@"Follow" handler:^(UITableViewRowAction *action, NSIndexPath *indexPath) {  

        NSLog(@"View Action fired");  
    }];  
    callAction.backgroundColor = [UIColor clearColor];  

    return @[callAction];  
}  

In Standard UITableViewRowAction we can't change , we can change only 
style
title
backgroundColor
backgroundEffect
