How To Make Fast Scrolling UITableViews With Custom Section Headers and Custom UITableViewCells




1. Create a new master detail application in XCode.

2. To set a custom flat navigation bar color create a two new objective-c categories with the code below and configure the navigation bar by importing the UINavigationBar+FlatUI.h file into your master view controller and calling configureFlatNavigationBarWithColor: on your navigation bar in the viewDidLoad method. You should end up with something like below.




// At the Top of the file
#import "UINavigationBar+FlatUI.h" 

- (void)viewDidLoad
{
    [super viewDidLoad];
 // Do any additional setup after loading the view, typically from a nib.
  self.navigationItem.leftBarButtonItem = self.editButtonItem;
  [self.navigationController.navigationBar configureFlatNavigationBarWithColor:[UIColor colorWithRed:44.0f/255.0f green:71.0f/255.0f blue:98.0f/255.0f alpha:1.0f]];
  UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(insertNewObject:)];
  self.navigationItem.rightBarButtonItem = addButton;
}

    [self setBackgroundImage:[UIImage imageWithColor:color cornerRadius:0]
               forBarMetrics:UIBarMetricsDefault & UIBarMetricsLandscapePhone];
    NSMutableDictionary *titleTextAttributes = [[self titleTextAttributes] mutableCopy];
    if (!titleTextAttributes) {
        titleTextAttributes = [NSMutableDictionary dictionary];
    }
    [titleTextAttributes setValue:[UIColor clearColor] forKey:UITextAttributeTextShadowColor];
    [titleTextAttributes setValue:[NSValue valueWithUIOffset:UIOffsetMake(0, 0)] forKey:UITextAttributeTextShadowOffset];
    [self setTitleTextAttributes:titleTextAttributes];
    if([self respondsToSelector:@selector(setShadowImage:)])
    {
        [self setShadowImage:[UIImage imageWithColor:[UIColor clearColor] cornerRadius:0]];
    }
}

@interface UIImage (FlatUI)

+ (UIImage *)imageWithColor:(UIColor *)color
               cornerRadius:(CGFloat)cornerRadius;

+ (UIImage *) backButtonImageWithColor:(UIColor *)color
                            barMetrics:(UIBarMetrics) metrics
                          cornerRadius:(CGFloat)cornerRadius;

UIImage+Color.m


+ (UIImage *)imageWithColor:(UIColor *)color
               cornerRadius:(CGFloat)cornerRadius {
    CGFloat minEdgeSize = edgeSizeFromCornerRadius(cornerRadius);
    CGRect rect = CGRectMake(0, 0, minEdgeSize, minEdgeSize);
    UIBezierPath *roundedRect = [UIBezierPath bezierPathWithRoundedRect:rect cornerRadius:cornerRadius];
    roundedRect.lineWidth = 0;
    UIGraphicsBeginImageContextWithOptions(rect.size, NO, 0.0f);
    [color setFill];
    [roundedRect fill];
    [roundedRect stroke];
    [roundedRect addClip];
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return [image resizableImageWithCapInsets:UIEdgeInsetsMake(cornerRadius, cornerRadius, cornerRadius, cornerRadius)];
}

+ (UIImage *) backButtonImageWithColor:(UIColor *)color
                            barMetrics:(UIBarMetrics) metrics
                          cornerRadius:(CGFloat)cornerRadius {

    CGSize size;
    if (metrics == UIBarMetricsDefault) {
        size = CGSizeMake(50, 30);
    }
    else {
        size = CGSizeMake(60, 23);
    }
    UIBezierPath *path = [self bezierPathForBackButtonInRect:CGRectMake(0, 0, size.width, size.height) cornerRadius:cornerRadius];
    UIGraphicsBeginImageContextWithOptions(size, NO, 0.0f);
    [color setFill];
    [path addClip];
    [path fill];
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return [image resizableImageWithCapInsets:UIEdgeInsetsMake(cornerRadius, 15, cornerRadius, cornerRadius)];
    
}

3. Now to make the navigation items look flat we can create another objective-c category to change the appearance. Import UIBarButtonItem+FlatUI.h in your master view controller Then add the code below to the viewDidLoad method. You should see something like this:



- (void)viewDidLoad
{
    [super viewDidLoad];
 // Do any additional setup after loading the view, typically from a nib.
  self.navigationItem.leftBarButtonItem = self.editButtonItem;
  [self.navigationController.navigationBar configureFlatNavigationBarWithColor:[UIColor colorWithRed:44.0f/255.0f green:71.0f/255.0f blue:98.0f/255.0f alpha:1.0f]];
  UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(insertNewObject:)];
  self.navigationItem.rightBarButtonItem = addButton;
  [UIBarButtonItem configureFlatButtonsWithColor:[UIColor colorWithRed:52.0f/255.0f green:152.0f/255.0f blue:219.0f/255.0f alpha:1.0f]
                                highlightedColor:[UIColor colorWithRed:41.0f/255 green:128.0f/255 blue:185.0f/255 alpha:1.0f]
                                    cornerRadius:3];
}

4. To create custom section header views in your tableview create a new section header view class and add a new category and add the code below to your master view controller. Also add the QuartzCore.Framework to your project. You should end up with something like this.








- (void)viewDidLoad
{
    [super viewDidLoad];
 // Do any additional setup after loading the view, typically from a nib.
  self.navigationItem.leftBarButtonItem = self.editButtonItem;
  [self.navigationController.navigationBar configureFlatNavigationBarWithColor:[UIColor colorWithRed:44.0f/255.0f green:71.0f/255.0f blue:98.0f/255.0f alpha:1.0f]];
  UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(insertNewObject:)];
  self.navigationItem.rightBarButtonItem = addButton;
  [UIBarButtonItem configureFlatButtonsWithColor:[UIColor colorWithRed:52.0f/255.0f green:152.0f/255.0f blue:219.0f/255.0f alpha:1.0f]
                                highlightedColor:[UIColor colorWithRed:41.0f/255 green:128.0f/255 blue:185.0f/255 alpha:1.0f]
                                    cornerRadius:3];
  // Add This Line
  self.tableView.sectionHeaderHeight = 46.0f;
}

#pragma mark - Table View

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{ // Change This to Non Zero Number
  return 100;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{ // Change This to Non Zero Number
  return 1;
}

// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
    
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    }


//  NSDate *object = _objects[indexPath.row];
  cell.textLabel.text = @"";
    return cell;
}

static NSString *SectionHeaderIdentifier = @"SectionHeaderIdentifier";

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
  SectionHeaderView *headerView = [self.tableView dequeueReusableHeaderFooterViewWithIdentifier:SectionHeaderIdentifier];
  if (headerView == nil) {
    headerView = [[SectionHeaderView alloc] initWithFrame:CGRectMake(0, 0, CGRectGetWidth(tableView.frame), tableView.sectionHeaderHeight)];
  }
  [headerView setTitle:@"Title" subTitle:@"Subtitle" image:[UIImage imageNamed:@"search-icon-timeline-translucent@2x.png"]];
  return headerView;
}

5. To custom draw fast tableview cells create a subclass of ABTableViewCell: https://github.com/enormego/ABTableViewCell, which draws the cell with core graphics. You should end up with something like this:
