UICollectionView adding image and button - xcode

Question

I used UICollectionView for displaying the images from CameraRoll, it is working fine, now I want to add the Camera button in the collectionview cell. I had written the code like this, button is not getting displayed.
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:#"collectionCell" forIndexPath:indexPath];
[self.cameraRoll thumbAtIndex:indexPath.row completionHandler:^(UIImage *thumb) {
UIImageView *imageView = [[UIImageView alloc] initWithImage:thumb];
imageView.frame = CGRectMake(0,0,cell.frame.size.width, cell.frame.size.height);
imageView.contentMode = UIViewContentModeScaleAspectFill;
[cell.contentView addSubview:imageView];
//Now Create Button
UIImage* img = [UIImage imageNamed:#"btn_take_pic"];
UIImageView *btnImage = [[UIImageView alloc] initWithImage:img];
btnImage.frame = CGRectMake(0,0, 50,50);
btnImage.frame = CGRectMake(0,0,cell.frame.size.width, cell.frame.size.height);
btnImage.contentMode = UIViewContentModeScaleAspectFill;
//End of create button
[cell.contentView addSubview:btnImage];//Add Button to the cell
}];
return cell;
}

Answer 1

Create Button like this
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:#"collectionCell" forIndexPath:indexPath];
//Add your image showing code here
//Now Create Button in cell
CGRect btnRect = CGRectMake(0, 0 , 30 , 30);
UIButton *cellBtn = [[UIButton alloc] initWithFrame:btnRect];
[cellBtn setBackgroundImage:[UIImage imageNamed:#"img.png"] forState:UIControlStateNormal];
[cellBtn setTitle:#"Text to Show" forState:UIControlStateNormal];
[cell.contentView addSubview:cellBtn];
[[cell cellBtn] addTarget:self action:#selector(CellBtnTapped:event:) forControlEvents:UIControlEventTouchUpInside];
return cell;
}
method for button tap
-(void)CellBtnTapped:(id)sender event:(id)event
{
// perform your action here that you want to do on button tap
}
But It is good that you should make a separate class for your CollectionViewCell and add all objects there, that you want to take in your collectionView cell.

This is the solution for the issue I mentioned above, I think it might be helpful for others, so positing the code here
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath
{
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:#"collectionCell" forIndexPath:indexPath];
if(indexPath.row>0)
[self.cameraRoll thumbAtIndex:(indexPath.row-1) completionHandler:^(UIImage *thumb) {
UIImageView *imageView = [[UIImageView alloc] initWithImage:thumb];
imageView.frame = CGRectMake(0,0,cell.frame.size.width, cell.frame.size.height);
imageView.contentMode = UIViewContentModeScaleAspectFill;
[cell.contentView addSubview:imageView];
}];
else{
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"btn_take_pic.png"]];
imageView.frame = CGRectMake(0,0,cell.frame.size.width, cell.frame.size.height);
imageView.contentMode = UIViewContentModeScaleAspectFill;
[cell.contentView addSubview:imageView];
}
return cell;
}
