Pass array of images from multiple UITableView selected cells - ios

Question

I am having such an issue right now. I have a UIViewController that has a UITableView, I have it set up so that when the UITableView is in editing mode it returns 3 - circles with the check marks. My UITableView has custom cells with in image and text. When I put the UITableView in edit mode, I am trying to pass an array of the images from multiple selected rows to a second view controller to use those images in a collection view, but I am just having a hard time passing the array of images. Any suggestions would be appreciated.
here is my TableView code:
-(void)didTapEditBUtton:(id)sender{
if ([self.ribbonTableView isEditing]) {
viewButton.hidden = YES;
headerLabel.hidden = NO;
[ribbonTableView setEditing:NO animated:YES];
[selectButton setTitle:#"select"];
}
else {
[selectButton setTitle:#"Cancel"];
// Turn on edit mode
headerLabel.hidden = YES;
viewButton.hidden = NO;
[ribbonTableView setEditing:YES animated:YES];
}
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection (NSInteger)section{
return [ribbonsArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
RibbonCustomCell *cell = (RibbonCustomCell *) [ribbonTableView dequeueReusableCellWithIdentifier:#"RibbonDetail"];
if (cell != nil)
{
RibbonsInfo *ribbonsInfo = [ribbonsArray objectAtIndex:indexPath.row];
//NSLog(#"%#", ribbonsInfo);
//Ribbon Image
cell.ribbonImageView.image = ribbonsInfo.ribbonImage;
cell.ribbonLabel.text = ribbonsInfo.ribbonName;
}
return cell;
}
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
return 3;
}
-(void)tableView:(UITableView *)tableView didSelectRowsAtIndexPath:(NSIndexPath *)indexPath{
}
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath{
}

You should take the property of NSMutableArray...
#property (nonatomic, strong) NSMutableArray *selectedImages;
- (void)viewDidLoad {
[super viewDidLoad];
self.selectedImages = [NSMutableArray new];
}
now when you select or deselect the cell the delegates are called -
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"%#",indexPath);
RibbonsInfo *ribbonsInfo = [ribbonsArray objectAtIndex:indexPath.row];
[self.selectedImages addObject:ribbonsInfo.ribbonImage];
}
- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"%#",indexPath);
if (self.selectedImages.count > 0) {
[self.selectedImages removeObjectAtIndex:indexPath.row];
}
}
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
return 3;
}
Now the selectedImages array contains the selected cell images and you can pass this array.
Hope it will solve your problem.
