POSet Delegate for Subview Controller

Body
copied!<p>i'm sure there is a simple way to solve this problem, but I can't figure out.</p> <p>I got a TabBarViewController with several Views. In some of the Views i loaded Tableviews with XML based content.</p> <p>My XML Parser works fine, I tested it before in a separate Projectfile. The Problem is that my TableViewController, for which I created a XMLAppDelegate to manage the parsing of my xmlfiles, still sends the methods to the main delegation file of my Project.</p> <pre><code>*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[MainAppDelegate slices]: unrecognized selector sent to instance 0x6d1fd00' </code></pre> <p>Like the error message shows, he tries to send it to my MainAppDelegate, instead of the XMLAppDelegate.</p> <p>I implemented the XMLAppDelegate in my Controller Files and init the delegate this way:</p> <p>The .h File of my Controller</p> <pre><code>#import <UIKit/UIKit.h> @class XMLAppDelegate, NewsDetailViewController; @interface NewsViewController : UITableViewController <UITableViewDelegate, UITableViewDataSource> { IBOutlet UITableView *newsTableView; XMLAppDelegate *appDelegate; NewsDetailViewController *ndvController; } @end </code></pre> <p>The .m File of my Controller</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; // self.navigationItem.rightBarButtonItem = self.editButtonItem; appDelegate = (XMLAppDelegate *)[[UIApplication sharedApplication] delegate]; self.title = @"Slices"; </code></pre> <p>}</p> <p>The Controller is loading into the TabBarView as separate .xib file. In this nib file i connected the Delegate and Data Source to my XMLAppDelegate.</p> <p>I still get this Error in the Log and the Application crashes as I try to switch to the Tab wish the TableViewController in it.</p> <p>Hope you understand my problem. Maybe someone could tell me what I'm doing wrong here setting the Delegate to my XMLAppDelegate.</p> <p>EDIT:</p> <p>To explain what I want to do:</p> <p>I have a XMLParser class to parse the File, a Slice class to store the Elements and XMLAppDelegate. From this files i get my XML results stored in an Array with name "slices".</p> <p>To use the Elements of the Array, for showing it up as Table or textlabel, I connected the TableViewController to the XMLAppDelegate (which parses my XML Document using the XMLParser File and stores Data in the Array).</p> <p>The Items of this Array are previously declared in the Files as Strings like this</p> <pre><code>@property (nonatomic, readwrite) NSInteger sliceID; @property (nonatomic, retain) NSString *image; @property (nonatomic, retain) NSString *title; @property (nonatomic, retain) NSString *text; </code></pre> <p>But like i said, the parser works. I think my problem seems to be that I requested appDelegate.slices, but the selector is not my XMLAppDelgate. The Error says it uses the Main Delegate, which don't have any propertys of the xml Delegate file.</p> <p>The TabView loads the NewsViewController, which calls for the array in the XMLAppDelegate. I implemented the files, connected the Delegate to TableView as Data Source and Delegate, but still it seems to take the main delegate.</p> <p>That drives me crazy. The Project is a Company Profile for a great Wellness Motel. I get the Contents from the CMS as XML-Files and need to access them from XMLAppDelegate, that delivers the sites contents.</p> <p>Hope you understand my bad English. ;)</p>
