YSPanel uses KVO and the Objective-C runtime to attach a view to the UIScrollView indicator and at the same time to provide some useful information.
Usage
[_scrollView addDefaultPanelWithBlock:^(CGPoint location, CGFloat percent) {
// Do your thing
}];
You can use it in a UIWebView by using _webView.scrollView instead. And if you have a UITextView or a UITableView, by calling the following convenience methods you can get the text line and the index path.
[_textView addTextViewPanelWithBlock:^(CGPoint location, NSInteger line) {
// Etc
}];
[_tableView addTableViewPanelWithBlock:^(CGPoint location, NSIndexPath *indexPath) {
// Etc
}];
Customization
By defeault YSPanel has a view attached to the scroll view's bar on the right.
@property (nonatomic, strong) YSPanelView *panelView;
It is possible to do some customizing to it and center it, but most important: you can add any view to it by setting the customView property. YSPanelView object has the following properties:
@property (nonatomic, strong) UIView *customView;
@property (nonatomic, strong) UILabel *titleLabel;
@property (nonatomic, assign) BOOL centered;
Installation
Manual: just drag and drop UIScrollView+YSPanel .h and .m onto your project. You have to include QuartzCore and, in case you aren't using arc, you should.
