[sendAGift setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:#"swipe.png"]]];
return #[sendAGift];
}

I think your class SimpleCell should contain the UIButton, in order perform reusing correctly.
It will be simpler if you create a custom UITableViewCell that contains all the UI actions over the cell and operate them within the cell, not in the UITableView itself.
Let's see an example:
Here's the customCell.h file:
#interface customCell : UITableViewCell {
UIButton *buttonSwipe;
}
#end
Here's the customCell.h file:
#import "customCell.h"
#implementation customCell
- (instancetype) initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
[self commonInit];
}
return self;
}
- (instancetype) initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
[self commonInit];
}
return self;
}
- (instancetype)initWithCoder:(NSCoder *)aDecoder {
self = [super initWithCoder:aDecoder];
if (self) {
[self commonInit];
}
return self;
}
- (void) commonInit {
buttonSwipe = [UIButton... // Initialize here your button
[buttonSwipe addTarget:self action:#selector(swipeCell:) forControlEvents:UIControlEventTouchUpInside];
}
- (void) swipeCell {
// Embed here the code that makes the effect of swipe the cell.
}
This is a fast-untested workaround with some predefined code, but I think it's a working example if you want to make your cells swipe with your own code.
But if you want a faster way, I recommend you to visit Chris Wendel and his SWTableViewCell on GitHub

You can call editActionsForRowAtIndexPath: method as
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:SELECTED_ROW_INDEX inSection:0];
[self tableView:self.tableView editActionsForRowAtIndexPath:indexPath];
try the below code
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
//swipe button allocation
UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
btn.tag = indexPath.row;
[cell.contentView addSubview:btn];
[btn addTarget:self action:#selector(buttonTouched:) forControlEvents:UIControlEventTouchUpInside];
cell.textLabel.text = [NSString stringWithFormat:#"%lu",indexPath.row];
return cell;
}
-(void)buttonTouched:(id)sender{
UIButton *btn = (UIButton *)sender;
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:btn.tag inSection:0];
[self tableView:self.tableView editActionsForRowAtIndexPath:indexPath];
}
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
// Return NO if you do not want the specified item to be editable.
return YES;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
[self.objects removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationFade];
} else if (editingStyle == UITableViewCellEditingStyleInsert) {
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view.
}
}
-(NSArray *)tableView:(UITableView *)tableView editActionsForRowAtIndexPath:(NSIndexPath *)indexPath{
NSLog(#"edit");
// code
return nil;
}
