An iOS Filter UIControl Subclass. Zero Graphics. Highly Customizable.
Inspired by National Geographics: Park Guides.
- In your XCode Project, take the SEFilterControl.h and .m & SEFilterKnob.h and .m from ios-filter-control folder and drag them into your project.
- Start using this new UIControl Subclass!
It supports iOS 4 to iOS 6
Here's a screenshot for different variations
You may watch a demo video on Youtube
The class is not very well documented. I tried documenting drawing code as much as I could.
There are sample codes that illustrate various parameters.
Somewhere, for example in your viewDidLoad, alloc and init the filter UIControl:
SEFilterControl *filter = [[SEFilterControl alloc]initWithFrame:CGRectMake(10, 20, 300, 70) Titles:[NSArray arrayWithObjects:@"Articles", @"News", @"Updates", @"Featured", @"Newest", @"Oldest", nil]];
This initializes our Filter Control using CGRect and Titles Array of NSStrings.
Note That height of the control is predifined as 70 and can't be changed
Then, add target for Value Change Event handling:
[filter addTarget:self action:@selector(filterValueChanged:) forControlEvents:UIControlEventValueChanged];
Don't forget to impelment the handler we specified later:
-(void)filterValueChanged:(SEFilterControl *) sender{
NSLog(@"%@", [NSString stringWithFormat:@"%d", sender.SelectedIndex]);
}
Adding to your UIView & releasing the object:
[self.view addSubview:filter];
[filter release];
To change the track color:
[filter setProgressColor:[UIColor lightGrayColor]];
To change the handler color:
[filter setHandlerColor:[UIColor darkGrayColor]];
To change the Titles text color:
[filter setTitlesColor:[UIColor blackColor]];
To change the Titles text font:
[filter setTitlesFont:[UIFont fontWithName:@"Didot" size:14]];
