This method will be called when user performs the swipe action
当用户执行滑动操作时将调用此方法
Just Place this in your CustomCell
只需将其放在您的 CustomCell 中
- (void)willTransitionToState:(UITableViewCellStateMask)state
{
[super willTransitionToState:state];
if ((state & UITableViewCellStateShowingDeleteConfirmationMask) == UITableViewCellStateShowingDeleteConfirmationMask)
{
for (UIView *subview in self.subviews)
{
if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"])
{
UIImageView *deleteBtn = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 64, 33)];
[deleteBtn setImage:[UIImage imageNamed:@"arrow_left_s11.png"]];
[[subview.subviews objectAtIndex:0] addSubview:deleteBtn];
}
}
}
}
You should not try that, you are not supposed to alter Apple's default views .
您不应该尝试这样做，您不应该更改 Apple 的默认视图。

If you only need to change the title of the button, you only need to add the titleForDeleteConfirmationButtonForRowAtIndexPath method.
如果只需要改变按钮的标题，只需要添加titleForDeleteConfirmationButtonForRowAtIndexPath方法即可。
- (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath {
return @"NewButtonName";
}

Try this:
尝试这个：
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (editingStyle == UITableViewCellEditingStyleDelete)
{
// Your Code
}
}
