[iOS9]3D-Touch-Example

참고 : https://github.com/minjoongkim/iOS-3D-Touch-Example

3D터치를 하기위해 View에 3d터치 등록.

*.m viewDidLoad

if (self.traitCollection.forceTouchCapability == UIForceTouchCapabilityAvailable) {
    [self registerForPreviewingWithDelegate:self sourceView:self.image1];
    [self registerForPreviewingWithDelegate:self sourceView:self.image2];
}
else {
    NSLog(@"ForceTouch not available. use LongPress...");
}

Head파일에 Delegate 등록.

@interface ViewController : UIViewController <UIViewControllerPreviewingDelegate>

픽을 했을때의 델리게이트. 
- (nullable UIViewController *)previewingContext:(id <UIViewControllerPreviewing>)previewingContext viewControllerForLocation:(CGPoint)location
{
    DetailImageViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"DetailImageView"];
    vc.preferredContentSize = CGSizeMake(0, 300);
    vc._delegate = self;
    if(previewingContext.sourceView.tag == 1) {
    vc.imageTag = 1;
    }else if(previewingContext.sourceView.tag == 2) {
    vc.imageTag = 2;
    }
    previewingContext.sourceRect = CGRectMake(0, 0, previewingContext.sourceView.frame.size.width, previewingContext.sourceView.frame.size.height);
    return vc;
}

- (void)previewingContext:(id <UIViewControllerPreviewing>)previewingContext commitViewController:(UIViewController *)viewControllerToCommit
{
    [self presentViewController:viewControllerToCommit animated:YES completion:nil];
}

포스터치를 했을때, 보이는 메뉴 설정.

DetailImageViewController.m

//add previewActionItem
- (NSArray <id <UIPreviewActionItem>> *)previewActionItems
{
    UIPreviewAction *action1 = [UIPreviewAction actionWithTitle:@"Soccer" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
    [self._delegate callParentControll:TRUE];
    }];
    UIPreviewAction *action2 = [UIPreviewAction actionWithTitle:@"BasketBall" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
    [self._delegate callParentControll:FALSE];
    }];
    UIPreviewAction *action3_1 = [UIPreviewAction actionWithTitle:@"BaseBall" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
    [self._delegate callParentControll:FALSE];
    }];
    UIPreviewAction *action3_2 = [UIPreviewAction actionWithTitle:@"VolleyBall" style:UIPreviewActionStyleDefault handler:^(UIPreviewAction * _Nonnull action, UIViewController * _Nonnull previewViewController) {
    [self._delegate callParentControll:FALSE];
    }];
    UIPreviewActionGroup *action3 = [UIPreviewActionGroup actionGroupWithTitle:@"More" style:UIPreviewActionStyleDestructive actions:@[action3_1, action3_2]];

    return @[action1, action2, action3];
}

ForceTouch 강도 체크.
