How can I load images from plist into UITableView?

I have saved videos and thumbnails in the Documents folder. And I gave the path to plist. In plist, I took an array and I added directories to the array. And in the dictionary I saved the image path

/Users/srikanth/Library/Application Support/iPhone Simulator/User/Applications/9E6E8B22-C946-4442-9209-75BB0E924434/Documents/image1

for the key image.

for video

/Users/srikanth/Library/Application Support/iPhone Simulator/User/Applications/9E6E8B22-C946-4442-9209-75BB0E924434/Documents/video1.mp4

for filePath.

I used the following code but it doesn't work. I am trying for images only. I need images to be loaded into a table in every cell.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
    static NSString *CellIdentifier = @"Cell";
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) 
    {
       cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];

        [cell setAccessoryType:UITableViewCellAccessoryDetailDisclosureButton];
        UIImageView *image2;
        image2.frame = CGRectMake(0.0f, 0.0f, 80.0f, 80.0f);
        image2.backgroundColor = [UIColor clearColor]; 

    }
    NSDictionary *dictOfplist = [cells objectAtIndex:indexPath.row];
    NSString *path = [dictOfplist objectForKey:@"imagePath"];
    NSLog("path: %@", path);
    return cell;
}  

- (void)viewDidLoad 
{
    [super viewDidLoad];
    self.title = @"Library";
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)];

    NSString* plistPath = [[NSBundle mainBundle] pathForResource:@"details" ofType:@"plist"];
    contentArray = [NSArray arrayWithContentsOfFile:plistPath];

    cells = [[NSMutableArray alloc]initWithCapacity:[contentArray count]];

    for(dCount = 0; dCount < [contentArray count]; dCount++)
        [cells addObject:[contentArray objectAtIndex:dCount]];
}

I got the path to images from plist.
 But how can I extract the image from the path. NSLog output signal:

path: /Users/srikanth/Library/Application Support/iPhone Simulator/User/Applications/9E6E8B22-C946-4442-9209-75BB0E924434/Documents/snook.jpg

How can I get an image from it and store it in cell.imageView.image?
How can I make this work. Thanks.

I see some problems in your code:

  • When you instantiate a UITableViewCell you are creating a UIImageView image2

    that is unassigned and hence a memory leak. This not normal?
  • You don't need to get a reference to the cell's UIImageView by tag. UITableViewCell already has a UIImageView and its image can be set using the property cell.imageView.image

    .


Where do you download UIImage? You say you are saving the image path, but there is no code to load the image from that path.
