One way to use a custom reorder control in iOS 8 apps.

CustomUITableViewCell.m

- (void)addSubview:(UIView *)view {
	// For the system-supplied reorder control, we want to eliminate the default
	// image and instead use our own. In order to achieve this, we need to use
	// the somewhat hacky way of confirming that this is indeed a system-created
	// UITableViewCellReorderControl by checking the class name. Icky? Icky.
	NSArray *relevantClassnameParts = @[@"ReorderControl"];
	NSString *viewClassname = NSStringFromClass([view class]);
	
	for (NSString *classname in relevantClassnameParts) {
		if (![viewClassname containsString:classname]) {
			// This is not the droid I'm looking for.
			continue;
		}
		
		// Make sure to remove all existing subviews from the reorder container
		// view.
		for (UIView *currentSubview in view.subviews) {
			[currentSubview removeFromSuperview];
		}
		
		// Create a UIImageView with the image we would actually like to use as
		// a reorder control, add it to the container view and set up layout
		// constraints to keep it centered within its container.
		UIImageView *controlImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"reorder_control"]];
		controlImageView.translatesAutoresizingMaskIntoConstraints = NO;
		[view addSubview:controlImageView];
		
		[view addConstraint:[NSLayoutConstraint constraintWithItem:controlImageView
														 attribute:NSLayoutAttributeCenterX
														 relatedBy:NSLayoutRelationEqual
															toItem:view
														 attribute:NSLayoutAttributeCenterX
														multiplier:1.0
														  constant:0.0]];
		[view addConstraint:[NSLayoutConstraint constraintWithItem:controlImageView
														 attribute:NSLayoutAttributeCenterY
														 relatedBy:NSLayoutRelationEqual
															toItem:view
														 attribute:NSLayoutAttributeCenterY
														multiplier:1.0
														  constant:0.0]];
	}
	
	[super addSubview:view];
}

Very prone to break in future iOS versions, but it's the best way I could find. Iterating through the view hierarchy is even more dangerous, IMO.
