Podfile

pod "ABFullScrollViewController"

Installation

For install this component you only need to download the ABFullScrollViewController folder and copy it into your proyect. Then you need to inherate your view controller of ABFullScrollViewController:

#import "ABFullScrollViewController.h"

@interface ViewController : ABFullScrollViewController <UITableViewDataSource>

@end

In .m file you need to implements the classes that allow you to customize the behaviour, for example:

//The view that you want to set in toolbar view
-(UIView *) headerView:(UIView *)view forTableView:(UITableView *)tableView
{
    [view setFrame:CGRectMake(0, 0, self.tableView.frame.size.width, HEADER_STANDARD_HEIGHT)];
    
    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0,
                                                               20/*status bar*/,
                                                               view.frame.size.width,
                                                               view.frame.size.height-20)];
    [label setFont:[UIFont fontWithName:@"Copperplate" size:20]];
    [label setTextColor:[UIColor blackColor]];
    [label setTextAlignment:NSTextAlignmentCenter];
    [label setText:@"ABFullScrollViewController"];
    [view addSubview:label];
        
    return view;
}

//The height of the toolbar view
-(float) headerHeightForTableView:(UITableView *)tableView
{
    return HEADER_STANDARD_HEIGHT;
}

//The color background color of the toolbar
- (UIColor *)toolbarBackgroundColor
{
    return [UIColor colorWithWhite:1.0 alpha:0.7];
}

//The minimum size that you want to show of the toolbar
- (float)minHeightWithoutHide
{
    return 20 /*status bar height*/;
}

For the last, you need to link in .xib file the tableViewDelegate, the toolbar and the tableView.

Notes

This component uses scrollViewDidScroll:, scrollViewDidEndDragging: willDecelerate: and scrollViewDidEndDecelerating so if you need to implment it in you class remember to call the super of it ;).
This component doesn't work fine with Autolayout :(.
