transform tableview - iphone

Question

I want to images display for cell. but this code display, only white tableview.Why? Please tell me. (I use not storyboard.)
TableCell.h
#import <UIKit/UIKit.h>

#end
TableCell.m

#implementation TableCell
#synthesize tableCellView;
#synthesize cellArray;
-(NSString *)reuseIdentifier
{
return #"cell";
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [cellArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [self.tableCellView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
for (UIImageView *view in cell.subviews)
{
[view removeFromSuperview];
}
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)];
imageView.image = [UIImage imageNamed:[cellArray objectAtIndex:indexPath.row]];
imageView.contentMode = UIViewContentModeCenter; // 画像サイズを合わせて貼る
CGAffineTransform rotateImage = CGAffineTransformMakeRotation(M_PI_2);
imageView.transform = rotateImage;
[cell addSubview:imageView];
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 220;
}

Answer 1

UITableViewCell by default already has support for images. You do not need to to add a new UIImageView as a subview ...
So instead of this:
for (UIImageView *view in cell.subviews)
{
[view removeFromSuperview];
}
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(10, 10, 200, 200)];
imageView.image = [UIImage imageNamed:[cellArray objectAtIndex:indexPath.row]];
imageView.contentMode = UIViewContentModeCenter; // 画像サイズを合わせて貼る
CGAffineTransform rotateImage = CGAffineTransformMakeRotation(M_PI_2);
imageView.transform = rotateImage;
[cell addSubview:imageView];
Write this:
cell.imageView.image = [UIImage imageNamed:[cellArray objectAtIndex:indexPath.row]];
Oh, I now notice that LOTS OF OTHER STUFF is wrong with your code! Sorry to say that. Other stuff you need to change:
Copy this method from your TableCell to your TableViewController: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath and remove the existing one
DELETE the TableCell class
I see you're also doing rotation... but leave that out for now. First try to make it work and THEN worry about rotation of the image.
Can I maybe advise you to read a book on iOS development? It seems as if you don't know what you're doing at all :(
But I do like to help you out. Can you maybe put all your code on http://www.github.com and invite me as a collaborator? My username is tomvanzummeren. I can make this app work for you.

Answer 2

your numberOfSectionsInTableView method might return 0. check the value of [arrays count]. And one more thing is you are not created UITableViewCell in proper way. That might be the problem too. Check this link for creating Custom UITableViewCell

Answer 3

Each UITableViewCell has an image support if it's style is default.
cell.imageView.image = yourImageView.image;
You don't need to do anything else.
You can change Image settings with changing yourImageView settings if you want.
