Otherwise it will fail.</p> <p>The interesting part is: The class Method will return the right Class every time.</p> <p>Is this a bug? Or is it supposed to work that way?</p> <p>Thanks..</p> <p>EDIT:</p> <p>Ok this did not solve the problem.. Here is what I do.. isMemberOfClass will always return NO</p> <p>Testcase:</p> <pre><code>- (void)test010_broadcastWait {    ...    GDataXMLDocument *doc = [[GDataXMLDocument alloc] initWithData:xmlData                                                           options:0 error:&amp;error];    Brick *newBrick = [self.parser loadBroadcastWaitBrick:doc.rootElement];    if (![newBrick isMemberOfClass:[BroadcastWaitBrick class]])        STFail(@"Wrong class-member");    .... } </code></pre> <p>BroadCastWait Class:</p> <p>import "BroadcastWaitBrick.h"</p> <pre><code>@implementation BroadcastWaitBrick -(id)initWithMessage:(NSString *)message { self = [super init]; if (self) { self.message = message; } return self; } ... </code></pre> <p>loadMethod:</p> <pre><code>-(BroadcastWaitBrick*)loadBroadcastWaitBrick:(GDataXMLElement*)gDataXMLElement { NSArray *messages = [gDataXMLElement elementsForName:@"broadcastMessage"]; GDataXMLElement *message = (GDataXMLElement*)[messages objectAtIndex:0]; BroadcastWaitBrick* brick = [[BroadcastWaitBrick alloc]initWithMessage:message.stringValue]; return brick; } </code></pre>
