    <p>Hi. I am developing an app and I would like to set the background in the app itself. Now I created an array of buttons using a for loop and setting tags, but for some reason when I click the buttons nothing happens.</p> <p>This is where the buttons are created:</p> <pre><code>-(void)showSettings { [[objc_getClass("DreamBoard") sharedInstance] hideAllExcept:mainView]; [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:.5]; if(toggled){ photos = [[NSArray arrayWithObjects: [UIImage imageWithContentsOfFile:@"/var/mobile/Library/iZoon/Images/Wallpapers/Wallpaper1.png"], [UIImage imageWithContentsOfFile:@"/var/mobile/Library/iZoon/Images/Wallpapers/Wallpaper2.png"], [UIImage imageWithContentsOfFile:@"/var/mobile/Library/iZoon/Images/Wallpapers/Wallpaper3.png"], [UIImage imageWithContentsOfFile:@"/var/mobile/Library/iZoon/Images/Wallpapers/Wallpaper4.png"], nil] retain]; w=0; for ( UIImage *image in photos ) { for (l = 0; l&lt;(int)photos.count; l++) { wallpaperButton = [[UIButton alloc] initWithFrame:CGRectMake(5,130+150*w,150,150)]; wallpaperButton.tag = l; [wallpaperButton setImage:image forState:UIControlStateNormal]; [wallpaperButton addTarget:self action:@selector(setWallpaper) forControlEvents:UIControlEventTouchDown]; [settingsMenu addSubview: wallpaperButton]; [wallpaperButton release]; } w++; } </code></pre> <p>Here is the function to set the wallpaper:</p> <pre><code>-(void)setWallpaper { UIImageView *bgView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,480)]; if ([wallpaperButton tag] == 1) { bgView.image = [UIImage imageWithContentsOfFile:@"/var/mobile/Library/iZoon/Images/Wallpapers/Wallpaper1.png"]; } else if ([wallpaperButton tag] == 0) { bgView.image = [UIImage imageWithContentsOfFile:@"/var/mobile/Library/iZoon/Wallpapers/Wallpaper2.png"]; } else if ([wallpaperButton tag] == 2) { bgView.image = [UIImage imageWithContentsOfFile:@"/var/mobile/Library/iZoon/ Wallpapers/Wallpaper3.png"]; } else if ([wallpaperButton tag] == 3) { bgView.image = [UIImage imageWithContentsOfFile:@"/var/mobile/Library/iZoon/Wallpapers/Wallpaper4.png"]; } [mainView insertSubview:bgView atIndex:0]; [bgView release]; </code></pre> <p>}</p> <p>Now the buttons display correctly but they don't do anything. Any help is appreciated. Thanks.</p>

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.
