Loading an image into UITableViewCell from an NSArray - iphone

Question

I have several hunderd .jpgs in /Resources within an iOS project.
Here is the viewDidLoad method:
- (void)viewDidLoad {
NSArray *allPosters = [[NSBundle mainBundle] pathsForResourcesOfType:#"jpg" inDirectory:#"."];
[super viewDidLoad];
}
The above successfully loads all of the .jpgs into an NSArray.
I simply need to display all of the .jpgs within this array in UITableViewCells in a UITableView
Here is the -(UITableViewCell *)tableView:cellForRowAtIndexPath: method:
-(UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
NSDictionary *posterDict = [allPosters objectAtIndex:indexPath.row];
NSString *pathToPoster= [posterDict objectForKey:#"image"];
UITableViewCell *cell =
[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell ==nil ) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]autorelease];
}
UIImage *theImage = [UIImage imageNamed:pathToPoster];
cell.ImageView.image = [allPosters objectAtIndex:indexPath.row];
return cell;
}
I know the issue is with cell.ImageView.image, but am not sure what the issue is? How can I grab each .jpg from the array and display in each row?

Answer 1

NSArray *allPosters = [[NSBundle mainBundle] pathsForResourcesOfType:#"jpg" inDirectory:#"."];
This will give you an array of paths (as suggested by the method name). Those paths are NSStrings.
But you are assigning this array to a local variable, and this variable will be gone after you left viewDidLoad.
so you have to change it into something like this:
allPosters = [[[NSBundle mainBundle] pathsForResourcesOfType:#"jpg" inDirectory:#"."] retain];
Another one:
NSDictionary *posterDict = [allPosters objectAtIndex:indexPath.row];
NSString *pathToPoster= [posterDict objectForKey:#"image"];
And this would definitely crash if you would have assigned the array correctly.
Change it into
NSString *pathToPoster = [allPosters objectAtIndex:indexPath.row];
Next one:
UIImage *theImage = [UIImage imageNamed:pathToPoster];
cell.ImageView.image = [allPosters objectAtIndex:indexPath.row];
UIImages imageNamed: doesn't work with paths, it needs filenames. And of course you want to assign the real image to the imageview and not the path to the poster. So change it:
UIImage *theImage = [UIImage imageNamed:[pathToPoster lastPathComponent]];
cell.imageView.image = theImage;

Answer 2

Try using [UIImage imageWithContentsOfFile:pathToPoster] rather than imageNamed. And set the value to the UIImage object.

Answer 3

It's probably just a typo, but it should be:
//lowercase "i" in imageView
cell.imageView.image = [allPosters objectAtIndex:indexPath.row];
Also- you are creating UIImage *theImage, but then you don't use it. What's going on there?
