JFDepthView

This is an iOS project for presenting views in iOS with a 3D effect to add depth. JFDepthView is only available in ARC and targets iOS 7.0+.

What's New:

February 26th, 2014

  • Added new animation options. In addition to the normal blur/push back affect you can now choose any of the following animation options.

    • JFDepthViewAnimationOptionPushBack
    • JFDepthViewAnimationOptionPushBackAndBlur
    • JFDepthViewAnimationOptionPerspectiveTransform
    • JFDepthViewAnimationOptionPerspectiveTransformAndBlur
  • Removed previously deprecated initializer initWithGestureRecognizer:

  • Removed GPUImage dependency (Bad idea to add it in the first place, my bad)
  • Reduced the number of frameworks needed down to only 3 (win!)
  • Now targets iOS 7+ only
  • Code refactoring and optimization
  • Added subtle bounce to presented view (Trust me, it's beautiful, like a baby unicorn)

January 29th, 2013

  • JFDepthView now supports both iPad and iPhone.

What It Looks Like:

How To Use It:

Basic Example

#import <JFDepthView/JFDepthView.h>

...

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.topViewController = [[TopViewController alloc] initWithNibName:@"TopViewController" bundle:nil];
    UITapGestureRecognizer* tapRec = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismiss)];
    self.depthView = [[JFDepthView alloc] init];
    self.depthView.delegate = self;

    // Optional properties, use these to customize your presentations
    // self.depthView.presentedViewWidth = 700;
    // self.depthView.presentedViewOriginY = 200;
    // self.depthView.blurAmount = JFDepthViewBlurAmountHard;
    // self.depthView.animationOption = JFDepthViewAnimationOptionPushBackAndBlur;
    self.depthView.recognizer = tapRec;
}

// Here is an IBAction that is called via a UIButton
- (IBAction)presentView:(id)sender {

    // Pass in the view controller you want to present (self.topViewController) 
    // and the view you want it to be displayed within (self.view)
    [self.depthView presentViewController:self.topViewController inView:self.view];

    // Optionally, if you don't care about rotation support, you can just pass in 
    // the view you want to present (self.topViewController.view) 
    // and the view you want it to be displayed within (self.view)
    // [self.depthView presentView:self.topViewController.view inView:self.view];
}

// Here is the simple dismissal method called from the tap recognizer passed into init method of JFDepthView
- (void)dismiss {
    [self.depthView dismissPresentedViewInView:self.view];
}

Customizable Properties

/**
 * JFDepthView - presentedViewWidth
 *
 * @return A custom float value representing the desired width of the presented view. Default value is 600.
 */
@property (nonatomic, assign) CGFloat presentedViewWidth;

/**
 * JFDepthView - presentedViewOriginY
 *
 * @return A custom float value representing the desired y origin of the presented view.
 * This is the space from the top of the presented view to the top of the view that it is contained in.
 */
@property (nonatomic, assign) CGFloat presentedViewOriginY;

/**
 * JFDepthView - blurAmount
 *
 * @return A JFDepthViewBlurAmount enum value representing to desired blur amount for the background view behind the presented view. Default value is JFDepthViewBlurAmountMedium.
 */
@property (nonatomic, assign) JFDepthViewBlurAmount blurAmount;

/**
 * JFDepthView - animationOption
 *
 * @return A JFDepthViewAnimationOption enum value representing the desired animation for the presentation. Default value is JFDepthViewAnimationOptionPerspectiveTransform.
 */
@property (nonatomic, assign) JFDepthViewAnimationOption animationOption;

/**
 * JFDepthView - hideStatusBarDuringPresentation
 *
 * @return A BOOL to tell JFDepthView to hide the status bar while presenting or not. Default is NO.
 */
@property (nonatomic, assign) BOOL hideStatusBarDuringPresentation;

/**
 * JFDepthView - recognizer
 *
 * @return The UIGestureRecognizer to be used on the area around the presentedView to dismiss the presentedView.
 */
@property (nonatomic, strong) UIGestureRecognizer* recognizer;

Add rotation support to your Presenting UIViewController

#pragma mark - JFDepthView Rotation Support For Presenting UIViewController

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
    [super didRotateFromInterfaceOrientation:fromInterfaceOrientation];
    [self.depthView didRotateFromInterfaceOrientation:fromInterfaceOrientation];
}

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    [super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
    [self.depthView willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
}

JFDepthView will notify your Presented UIViewController of the didRotate... and willRotate... events so you can do what ever customizations need to be done to your presented view

#pragma mark - JFDepthView Rotation Support for Presented UIViewController

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation
{
    NSLog(@"Top View Controller Received didRotateFromInterfaceOrientation: event from JFDepthView");
}

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
    NSLog(@"Top View Controller Received willRotateToInterfaceOrientation:duration: event from JFDepthView");
}

Please see the example project include in this repo for an example of how to use this project.

Delegate Methods:

- (void)willPresentDepthView:(JFDepthView*)depthView;
- (void)didPresentDepthView:(JFDepthView*)depthView;
- (void)willDismissDepthView:(JFDepthView*)depthView;
- (void)didDismissDepthView:(JFDepthView*)depthView;
