How can I retrieve detail disclosure button's view in ios 7? - iphone

Question

Here, I'm trying to get the view of an accessoryButton in ios7.
My issue is similar to this one, but in a different version as I'm upgrading an ios 6 app to ios 7,
how can I retrieve detail disclosure buttons view
This work fine in ios 6, but it doesn't work in ios 7, I wonder why... here's my code:
- (UIView *)accessoryOfCell:(UITableViewCell *)tableViewCell
//Code inside method. I don't know how to quick indent so forget this {}
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"7.0")) {
for (UIView *view in [tableViewCell subviews]) {
//this loop 1 times, return view has class UITableViewCellScrollView
for (UIView *subview in [view subviews]) {
//this loop 3 times, return subview as:
//UITableViewCellContentView, _UITableViewCellSeparatorView , UITableViewCellDetailDisclosureView
NSLog(#"%#", subview.class);
if ([view isKindOfClass:[UIButton class]]) {
return view;
}
}
}
}
else {
// in ios 6, this works super fine!
for (UIView *view in [tableViewCell subviews]) {
if ([view isKindOfClass:[UIButton class]]) {
return view;
}
}
}
return nil;
So with my code above won't return anything as UIButton in ios7.
NOTE: the "tableViewCell.accessoryView" return nil, I wonder why, since I choose detail disclosure in storyboard.
Any idea please?
EDIT NOTE:
I can as well put the code like this:
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"7.0")) {
return ((UIView *)tableViewCell.subviews[0]).subviews[2];
} else { ... }
But I don't wanna, since this may cause update app in the future a pain in the #$$
EDIT NOTE #2:
This method is being called inside
- (void)tableView:(UITableView *)tableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath {
...
}
