Tap and Hold UITableViewCell and move to other UITableView


i have problems / understanding troubles with multiple UITableViews in one ViewController ... I have 4 UItableviews. So i created foreach a:
NSObjet<TableViewDelegate/Source>
Then i created in the ViewController a UILongPressGestureRecognizer -Action and get the item i selected and hold to drag it into a other UITableView

Works fine, i get my cell but how can i hold it? And is there a way to find out in which tableview i drop the UITableViewCell?

enter image description here

SOLVED SPECIAL THANKS TO user1966730 (Kristof)
My new UIVIEW.h:

@interface MovingCell : UIView
@property(strong,nonatomic)UIImageView *imageViewCell;
@property(strong,nonatomic)UITableViewCell *cell;    //This should be later my Custom Cell
@property(strong,nonatomic)NSIndexPath *indexPath;
@property(strong,nonatomic)UITableView* tableView;

-(void)displayCell:(UITableViewCell *)cell inView:(UIView *)mainView;
-(void)bringViewOverSelectedCell:(UIView *)mainView;

@end

UIVIEW.m:

#import "MovingCell.h"

#define _Shadow_Space_Height 7.0f

@implementation MovingCell

@synthesize imageViewCell = _imageViewCell;
@synthesize cell = _cell;

-(void)displayCell:(UITableViewCell *)cell inView:(UIView *)mainView{

    self.cell = cell;

    //Screenshot of touchedCell
    UIGraphicsBeginImageContext(cell.bounds.size);
    [cell.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *screenShot = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    // init imageView for cell snapshop if needed
    if (_imageViewCell == nil)
    {
        _imageViewCell = [[UIImageView alloc] init];
        [self addSubview:_imageViewCell];
    }

    // set current snapshot as image
    [_imageViewCell setImage: screenShot];

    // calculate position and frame
    CGRect viewFrameInMainView = [mainView convertRect:cell.frame fromView:cell.superview];
    _imageViewCell.frame = viewFrameInMainView;
    viewFrameInMainView.origin.x -= _Shadow_Space_Width;
    viewFrameInMainView.origin.y -= _Shadow_Space_Height;
    viewFrameInMainView.size.width += _Shadow_Space_Width * 2.0f;
    viewFrameInMainView.size.height += _Shadow_Space_Height * 2.0f;
    self.frame = viewFrameInMainView;

    // set write frames for subviews
    _imageViewCell.frame = CGRectMake(_Shadow_Space_Width, _Shadow_Space_Height, _imageViewCell.frame.size.width, _imageViewCell.frame.size.height);


    self.clipsToBounds = YES;

So finally im so happy about that, after 3 Days trying different thinks Kristof help me to find out the right way and i can do my work to customize this basic solution. Hope we can help other with this. :) Have a nice Weekend :)

Long time ago, i've worked with UITableView and custom draging, but i think there is no standard way to do this. If u drag a cell to move this cell around, u can't leave the table view.

My idea for you, think about customizing of your cell. I added a new class called MoveCellView and each cell had a long press gesture recognizer. Now, let the magic begin.

My Move Cell

#define MFCMV_SHADOW_SPACE_HEIGHT 7.0f
#define MFCMV_SHADOW_SPACE_WIDTH 7.0f

@implementation MoveCellView

@synthesize imageViewCell = _imageViewCell;
@synthesize cell = _cell;

- (void)displayCell:(UITableViewCell *)cell inView:(UIView *)mainView
{
    self.cell = cell;

    // init shadow view if needed with strechable image 
    if (_imageViewShadow == nil) 
    {
        _imageViewShadow = [[UIImageView alloc] initWithImage:[[UIImage imageNamed:@"FormEditorCellBackgroundShadowOnMove"] stretchableImageWithLeftCapWidth:14.0f topCapHeight:14.0f]];
        _imageViewCell.frame = self.bounds;
        [self addSubview:_imageViewShadow];
    }

    // get current view snapshot form cell
    UIGraphicsBeginImageContext(cell.bounds.size);

    [cell.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *imageCellSnapshot = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();


    // init imageView for cell snapshop if needed
    if (_imageViewCell == nil) 
    {
        _imageViewCell = [[UIImageView alloc] init];
        [self addSubview:_imageViewCell];
    }

    // set current snapshot as image
    [_imageViewCell setImage: imageCellSnapshot];

    // calculate position and frame
    CGRect viewFrameInMainView = [mainView convertRect:cell.frame fromView:cell.superview];
    _imageViewCell.frame = viewFrameInMainView;
    viewFrameInMainView.origin.x -= MFCMV_SHADOW_SPACE_WIDTH;
    viewFrameInMainView.origin.y -= MFCMV_SHADOW_SPACE_HEIGHT;
    viewFrameInMainView.size.width += MFCMV_SHADOW_SPACE_WIDTH * 2.0f;
    viewFrameInMainView.size.height += MFCMV_SHADOW_SPACE_HEIGHT * 2.0f;
    self.frame = viewFrameInMainView;

    // set write frames for subviews
    _imageViewShadow.frame = self.bounds;
    _imageViewCell.frame = CGRectMake(MFCMV_SHADOW_SPACE_WIDTH, MFCMV_SHADOW_SPACE_HEIGHT, _imageViewCell.frame.size.width, _imageViewCell.frame.size.height);


    self.clipsToBounds = YES;
    [mainView addSubview:self];
}

- (void)bringViewOverSelectedCell:(UIView *)mainView
{
    if (self.cell == nil) 
    {
        return;
    }

    // calculate position and frame
    CGRect viewFrameInMainView = [mainView convertRect:self.cell.frame fromView:self.cell.superview];
    viewFrameInMainView.origin.x -= MFCMV_SHADOW_SPACE_WIDTH;
    viewFrameInMainView.origin.y -= MFCMV_SHADOW_SPACE_HEIGHT;
    viewFrameInMainView.size.width += MFCMV_SHADOW_SPACE_WIDTH * 2.0f;
    viewFrameInMainView.size.height += MFCMV_SHADOW_SPACE_HEIGHT * 2.0f;
    self.frame = viewFrameInMainView;

}

After a long press gesture was detected i moved the pressed cell to this move cell. i also moved the long pressed gesture.

- (void)dispatchLongPressOnCellBegan:(UILongPressGestureRecognizer *)gestureRecognizer
{
    XLog();

    UITableViewCell *cell = (UITableViewCell *)gestureRecognizer.view;

    // init if needed
    if (_cellMoveAnimationView == nil) 
    {
        _cellMoveAnimationView = [[MFCellMoveView alloc] initWithFrame:CGRectMake(0.0f , 0.0f, 10.0f, 10.0f)];
    }

    // save start index path of this cell
    _startIndexPath = [[_tableViewEditor indexPathForCell:cell] copy];

    _cellMoveAnimationView.hidden = NO;
    _cellMoveAnimationView.alpha = 0.8f;
    [_cellMoveAnimationView displayCell:cell inView:self.view];

    [_cellMoveAnimationView addGestureRecognizer:gestureRecognizer];

    _cellMoveLastTouchPoint = [gestureRecognizer locationInView:self.view];

    cell.hidden = YES;
}

Now your moving cell with the gesture is on the top of your view controller. So you can move this cell around. For your next step, bring the cell to an other UITableView, i have no idea, at this time. I think you must remove the cell action in the first table view, then add this action in the next table view and also add the item.

I hope i helps a little bit.
