    <p>I have a circle at the center of the screen, and I am allocating around this fixed circle (a UIImageView) a series of UIlabels. the number of the labels is given by the number of elements in an NSMutableArray, and the position of the labels depends on the number of labels. I can't give a fixed x and y coordinate to the labels, because the number of labels will vary.</p> <p>I tried using this code:</p> <pre><code>- (void)loadContent{ NSString *filename6 = [[NSUserDefaults standardUserDefaults]objectForKey:@"Setting"]; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *groupPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@", filename6]]; NSString *fileContent = [[NSString alloc] initWithContentsOfFile:groupPath]; NSMutableArray* array = [[NSMutableArray alloc] initWithArray:[fileContent componentsSeparatedByString:@", "]]; int arrayCount = array.count; int yCoordinate = (2*M_PI) / arrayCount; int xCoordinate = ; for(int i = 0; i &lt; [array count]; i++){ CGRect textframe = CGRectMake( the xcoordinate, the ycoordinate, 328, 30); NSString *nameOfGroup = [array objectAtIndex:i]; UITextView* theGroupTextLabel; theGroupTextLabel = [[UITextView alloc] initWithFrame: textframe]; [theGroupTextLabel setText: nameOfGroup]; [theGroupTextLabel setTextColor: [UIColor redColor]]; [self.view addSubview:theGroupTextLabel]; //theGroupTextLabel.enabled = NO; theGroupTextLabel.backgroundColor = [UIColor clearColor]; theGroupTextLabel.layer.borderWidth = 3.5f; theGroupTextLabel.layer.borderColor = [[UIColor blackColor] CGColor]; int z; z = z + 1; theGroupTextLabel.tag = z; } } </code></pre> <p>but i am stuck with finding the right equation for the:</p> <pre><code>int yCoordinate = (2*M_PI) / arrayCount; int xCoordinate = ; </code></pre> <p>...coordinates. Any ideas? Is this the right method I am using?</p>

    1. COHow are these labels being positioned? In a grid? or are they in a circle around the image(like the numbers on the face of a clock)? I noticed you have an M_PI in there so I'm guessing it's like a clock?

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.
