The FlipNumberView is simulating an analog flip display (like those for the departure time on the airport). It's well abstracted and damn easy to use. Please open a Github issue, if you think anything is missing or wrong.
See screenshots of the example project below.
If you are using this class, you may list your app on the wiki page.
A) Use CocoaPods (preferred way, see cocoapods website)
- add
pod 'JDFlipNumberView'to your Podfile- run
pod install
B) Manual way (not needed, if you use cocoapods):
- Add all files from
JDFlipNumberView/JDFlipNumberView/*to your project, including theJDFlipNumberView.bundle- Link with the
QuartzCore.framework
The two main classes are:
JDFlipNumberView
The Standard FlipNumberView. It shows an integer value as FlipView. It has a choosable amount of digits.JDDateCountdownFlipView
A date countdown. Just init with a target date and it will show the remaining days, hours, minutes and seconds until that date.
In any case, after installing, you only need to follow some simple steps to get started. Here is a full example usage:
Example: A 4 digit FlipNumberView animating down every second.
// create a new FlipNumberView, set a value, start an animation
JDFlipNumberView *flipNumberView = [[JDFlipNumberView alloc] initWithDigitCount:4];
flipNumberView.value = 1337;
[flipNumberView animateDownWithTimeInterval: 1.0];
// add to view hierarchy and resize
[self.view addSubview: flipNumberView];
flipNumberView.frame = CGRectMake(20,100,300,100);
That's it. This will display a working, flipping, animating countdown view!
Basic animations:
- (void)setValue:(NSInteger)newValue animated:(BOOL)animated;
- (void)animateToNextNumber;
- (void)animateToPreviousNumber;
Targeted animation over time:
- (void)animateToValue:(NSInteger)newValue duration:(CGFloat)duration;
Timed animation without target value:
- (void)animateUpWithTimeInterval:(NSTimeInterval)timeInterval;
- (void)animateDownWithTimeInterval:(NSTimeInterval)timeInterval;
You may use the original .psd file from the gfx folder to create custom graphics.
A) Replace original images
Replace the images within the JDFlipNumberView.bundle. But the next pod install will revert your changes.
B) Use your own bundle
Add your own graphics bundle to your project. You need one image per digit. 0.png, 1.png, 2.png, etc.
Before using any FlipNumberViews, set your own images like this:
[JD_IMG_FACTORY generateImagesFromBundleNamed:@"yourBundleName"]
