    <p>I have a class that parses the result of a web service call. Based on that result it calls a method in another class and that method is supposed to change the image in a UIImageView. But it won't set the image and I have no idea why.</p> <p>First class relevant parts. 'Server' value does come back "rb".</p> <pre><code>#import "GetBBYprod.h" #import "MyViewController.h" static NSString *kAblue = @"A_blue.png"; static NSString *kBblue = @"B_blue.png"; static NSString *kCblue = @"C_blue.png"; @implementation GetBBYprod @synthesize vc; -(id)init { if (self = [super init]) { vc = [[MyViewController alloc] init]; } return self; } -(void)connectionDidFinishLoading:(NSURLConnection *)conn { NSString *bbyProdString = [[NSString alloc] initWithData:bbyProdData encoding:NSUTF8StringEncoding]; NSString *server = [bbyProdString substringToIndex:2]; if ([server isEqualToString:@"rb"]) { [vc setAlight:kBblue]; } } </code></pre> <p>So that sends kBblue to the method setAlight in my MyViewController class. (The value of kBblue is "B_blue.png".</p> <p>So in my MyViewController class, setAlight method:</p> <pre><code>-(id)init { if (self = [super init]) { aImage = [[UIImageView alloc] init]; bImage = [[UIImageView alloc] init]; cImage = [[UIImageView alloc] init]; } return self; } -(void)setAlight:(NSString *)aValue { NSLog(@"image name: %@", aValue); [aImage setImage:[UIImage imageNamed:aValue]]; } </code></pre> <p>That will successfully log "image name: B_blue.png" so I know the data is being passed and the method is being called. But it won't set the image in the aImage UIImageView. Why?</p> <p><strong>EDIT</strong></p> <ul> <li>I'm using a xib and the imageView is assigned a default image.</li> <li>All of my connections are connected in the xib and they all look correct.</li> <li>There is no whitespace in the string that I'm passing.</li> <li>I can tell that the image hasn't been set because it will be very obvious to me when it's set correctly.</li> </ul>

    1. COAre you sure there isn't whitespace at the end of aValue? A simple test is to do ```NSLog(@"image name: [%@]", aValue);``` and see if the ] is really right after the last file name character.

    3. COMaybe a threading thing? You can only do UI things from the main thread. Maybe try [self performSelectorOnMainThread:@selector(setAlight:) withObject:kBblue waitUntilDone:NO];

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.
