YIDragScrollBar 1.2.0

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

• 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

Install via CocoaPods

pod 'YIDragScrollBar'

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");
}

If we meet some day, and you think this stuff is worth it, you can buy me a beer in return.

yidragscrollbar's Issues

any plans for swift?

I need a control like this for swift.
not aware of this existing anywhere else.

Would it be possible to add a "bubble" view that would scroll alongside with the scrollbar?

It would be interesting to have support to display a "bubble" view that would scroll alongside with the scrollbar.

Would that be possible?
