YIDragScrollBar 1.2.0

Attaches draggable scroll bar on top of original UIScrollView for iOS5+, works like a drug.

ScreenShot1

  • YIDragScrollBar uses JRSwizzle to extend UIScrollView's functionality, and does not use any private APIs.
  • Installed UIScrollView subclass will add another dragging-scrollIndicator on top of it and temporarily hides original-scrollIndicator while dragging.
  • Several application tests have been passed including:
    • vertical/horizontal dragging
    • zooming
    • device rotation
    • indicatorStyle (black & white)
    • contentInsets/scrollIndicatorInsets
    • UIScrollView subclasses (e.g. UITableView, UIWebView, UITextView)
    • never intercepts touches while original-scrollIndicator is hidden

How to use

Just import the files, and all set!

#import "YIDragScrollBar.h"

...

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // set NO to disable dragScrollBar on each scrollView-init. defalut = YES.
    // [UIScrollView setDefaultDragScrollBarEnabled:NO];

    return YES;
}

Set scrollView.dragScrollBarDelegate to detect dragScrollBar began/ended.


- (void)viewDidLoad
{
    ...

    self.scrollView.dragScrollBarDelegate = self;
}

- (void)dragScrollBarWillBeginDragging:(UIScrollView *)scrollView
{
    NSLog(@"dragScrollBar began");
}

- (void)dragScrollBarWillEndDragging:(UIScrollView *)scrollView
{
    NSLog(@"dragScrollBar ended");
}
