POUITabBar – setItems:animated: Crashes
text
Body
copied!<p>So I have a UITabView Controller that was created in interface builder. The title and image properties of UITabBarItem were set in IB. A Tab Bar Controller object is present in the xib and all necessary connections are made. I am able to call simple commands such as </p> <p>[tabBarController setSelectedIndex:1]; </p> <p>Everything works fine but when I set the 'items' property, I crash. Maybe I am having a memory management problem?</p> <p>Here is the crashing code:</p> <pre><code>NSMutableArray *modifiedItems = [[tabBarController.tabBar items] mutableCopy]; [modifiedItems removeObjectAtIndex:2]; NSArray *newItems = [[NSArray alloc] initWithArray:modifiedItems]; -->[tabBarController.tabBar setItems:newItems animated:NO]; </code></pre> <p><strong>* Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Directly modifying a tab bar managed by a tab bar controller is not allowed.' *</strong> Call stack at first throw:</p> <pre><code>0 CoreFoundation 0x02b9bb99 __exceptionPreprocess + 185 1 libobjc.A.dylib 0x02ceb40e objc_exception_throw + 47 2 CoreFoundation 0x02b54238 +[NSException raise:format:arguments:] + 136 3 CoreFoundation 0x02b541aa +[NSException raise:format:] + 58 4 UIKit 0x005f7019 -[UITabBar setItems:animated:] + 2037 5 Zag Map 0x00003422 -[ZagMapAppDelegate iPodTouchRemoval] + 270 6 Zag Map 0x00002eea -[ZagMapAppDelegate applicationDidFinishLaunching:] + 551 7 UIKit 0x003faf80 -[UIApplication _callInitializationDelegatesForURL:payload:suspended:] + 1252 8 UIKit 0x003fd3b0 -[UIApplication _runWithURL:payload:launchOrientation:statusBarStyle:statusBarHidden:] + 346 9 UIKit 0x004073ec -[UIApplication handleEvent:withNewEvent:] + 1958 10 UIKit 0x003ffb3c -[UIApplication sendEvent:] + 71 11 UIKit 0x004049bf _UIApplicationHandleEvent + 7672 12 GraphicsServices 0x03357822 PurpleEventCallback + 1550 13 CoreFoundation 0x02b7cff4 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ + 52 14 CoreFoundation 0x02add807 __CFRunLoopDoSource1 + 215 15 CoreFoundation 0x02adaa93 __CFRunLoopRun + 979 16 CoreFoundation 0x02ada350 CFRunLoopRunSpecific + 208 17 CoreFoundation 0x02ada271 CFRunLoopRunInMode + 97 18 UIKit 0x003fcc6d -[UIApplication _run] + 625 19 UIKit 0x00408af2 UIApplicationMain + 1160 20 Zag Map 0x00002ca0 main + 102 21 Zag Map 0x00002c31 start + 53 terminate called after throwing an instance of 'NSException' </code></pre> <p>My NSArray and NSMutableArray appear to be fine considering they came straight out of the functioning UITabBar. It returned three objects, then two. I hope I'm just overlooking something stupid here. Any ideas I would really appreciate.</p>
