Problem with displaying images

I have developed an iPad app using core data to store employee details. I have only three fields: Name, id and department. On launching the application the names are displayed in a table view and on clicking in any row, the respective id and department is displayed in the detail view.

Now I want to display picture of the employees in detail view too but not by storing them in core data. I have a subfolder named "Images" in the resources folder in which the pictures are stored in order of the names displayed in the table view.

Please help me in this regard.

You should read something about transient properties of CoreData entities. You can easily add property image for example, which is transient (= does not store values to underlying persistent store), which can read/write your images directly from your file system. In other words, you can have everything in one place and no entity in one class, image handling in another, etc.

Use the static method [NSBundle mainBundle] to get an object that represents your application bundle. With this you can then call the instance method - (NSString *)pathForResource:(NSString *)name ofType:(NSString *)extension to get a path to the image you have stored. Once you have the path, you can create an instance of UIImage with the image path. You can then create a UIImageView (which could be done in interface builder if you wish), of which you can then set the image to your instance of UIImage.

For example:

NSString* pathToImage = [[NSBundle mainBundle] pathForResource:@"pictureOfJohn" ofType:@"png"];
UIImage* image = [UIImage imageWithContentsOfFile:pathToImage];
UIImageView* imageView = [[UIImageView alloc] init];
imageView.image = image;
[myEnclosingView addSubview:imageView];
[imageView release];

Note that the creation and adding of the imageView could be done in interface builder.
