    <p>Ok so I i am trying to make the user pick an image from the iphone photos and save that image as an image on a button. When the user shuts down the app and opens it again I want the user to see his saved image again :) theButton contains the sender of which button is clicked btw.</p> <p>I can do the part where the user can put the image as the button image. I use this line to set the image</p> <pre><code>[theButton setImage:btnImage forState:UIControlStateNormal]; </code></pre> <p>Now I am wondering how can I access that image of the button? So I can save and load it?</p> <p>I use this code according to a tutorial but I am stuck with the load part because apparently I do not have to use Imageview because it is only readable :) My code for that:</p> <pre><code>//SAVE -(NSString *)pathOfFile{ NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsFolder = [paths objectAtIndex:0]; return [documentsFolder stringByAppendingFormat:@"myfile.plist"]; } -(void)applicationWillTerminate:(NSNotification*)notification{ NSMutableArray *array = [[NSMutableArray alloc]init]; [array addObject: tileOne.imageView]; [array addObject: tileTwo.imageView]; [array writeToFile:[self pathOfFile] atomically:YES]; } //LOAD - (void)viewDidLoad { NSString *filePath = [self pathOfFile]; if ([[NSFileManager defaultManager] fileExistsAtPath:filePath]) { NSArray *array = [[NSArray alloc]initWithContentsOfFile:filePath]; //Here it says read only, what to use then? tileOne.imageView = [array objectAtIndex:0]; } UIApplication *app = [UIApplication sharedApplication]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(applicationWillTerminate:) name:UIApplicationWillTerminateNotification object:app]; [super viewDidLoad]; } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
