POKeep getting breakpoint error when trying to run iOS application on iphone simulator with xcode 5
text
Body
copied!<p>I just started creating a new checklist app for the first time.</p> <p>So far I have added a Table View object and Table View Cell object to the app's UI in main.storyboard.</p> <p>I then went to my View Controller header file and made sure to change the superclass type to "UITableViewController".</p> <p>I then went to my View Controller main file and added the following methods:</p> <pre><code>-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 1; } -(UITableViewCell *)tableview:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"ChecklistItem"]; return cell; } </code></pre> <p>I keep getting a breakpoint error and cannot get the app to run on the iPhone simulator. I have tried starting from scratch and recreating this app 3 times now and have also tried using different simulators, and still nothing is working.</p> <p>Whenever I try running the app this is the final output in the debug console:</p> <pre><code>libc++abi.dylib: terminating with uncaught exception of type NSException (lldb) </code></pre> <p>Also, here is a link to a screenshot of what my xcode looks like when I try to run the program and get the breakpoint error: <a href="http://oi40.tinypic.com/25im3kn.jpg" rel="nofollow">http://oi40.tinypic.com/25im3kn.jpg</a></p> <p>I have gotten breakpoint errors many times in the past but usually can fix everything by just going to Debug > Deactivate Breakpoints but that is not working for me right now.</p> <p>Any help is greatly appreciated thank you.</p> <p>PS. Also, here is the entire output in the debug console log:</p> <pre><code>2013-12-18 18:25:55.183 Checklists[4910:70b] *** Assertion failure in -[UITableView _configureCellForDisplay:forIndexPath:], /SourceCache/UIKit_Sim/UIKit- 2903.23/UITableView.m:6246 2013-12-18 18:25:55.190 Checklists[4910:70b] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:' *** First throw call stack: ( 0 CoreFoundation 0x017385e4 __exceptionPreprocess + 180 1 libobjc.A.dylib 0x014bb8b6 objc_exception_throw + 44 2 CoreFoundation 0x01738448 +[NSException raise:format:arguments:] + 136 3 Foundation 0x0109bfee -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:] + 116 4 UIKit 0x003123d5 __53-[UITableView _configureCellForDisplay:forIndexPath:]_block_invoke + 426 5 UIKit 0x0028b3ef +[UIView(Animation) performWithoutAnimation:] + 82 6 UIKit 0x0028b438 +[UIView(Animation) _performWithoutAnimation:] + 40 7 UIKit 0x00312226 -[UITableView _configureCellForDisplay:forIndexPath:] + 108 8 UIKit 0x0031863d -[UITableView _createPreparedCellForGlobalRow:withIndexPath:] + 442 9 UIKit 0x003186f3 -[UITableView _createPreparedCellForGlobalRow:] + 69 10 UIKit 0x002fc774 -[UITableView _updateVisibleCellsNow:] + 2378 11 UIKit 0x0030fe95 -[UITableView layoutSubviews] + 213 12 UIKit 0x00294267 -[UIView(CALayerDelegate) layoutSublayersOfLayer:] + 355 13 libobjc.A.dylib 0x014cd81f -[NSObject performSelector:withObject:] + 70 14 QuartzCore 0x03b462ea -[CALayer layoutSublayers] + 148 15 QuartzCore 0x03b3a0d4 _ZN2CA5Layer16layout_if_neededEPNS_11TransactionE + 380 16 QuartzCore 0x03b46235 -[CALayer layoutIfNeeded] + 160 17 UIKit 0x0034f613 -[UIViewController window:setupWithInterfaceOrientation:] + 304 18 UIKit 0x0026e177 -[UIWindow _setRotatableClient:toOrientation:updateStatusBar:duration:force:isRotating:] + 5212 19 UIKit 0x0026cd16 -[UIWindow _setRotatableClient:toOrientation:updateStatusBar:duration:force:] + 82 20 UIKit 0x0026cbe8 -[UIWindow _setRotatableViewOrientation:updateStatusBar:duration:force:] + 117 21 UIKit 0x0026cc70 -[UIWindow _setRotatableViewOrientation:duration:force:] + 67 22 UIKit 0x0026bd0a __57-[UIWindow _updateToInterfaceOrientation:duration:force:]_block_invoke + 120 23 UIKit 0x0026bc6c -[UIWindow _updateToInterfaceOrientation:duration:force:] + 400 24 UIKit 0x0026c9c3 -[UIWindow setAutorotates:forceUpdateInterfaceOrientation:] + 870 25 UIKit 0x0026ffb6 -[UIWindow setDelegate:] + 449 26 UIKit 0x00341737 -[UIViewController _tryBecomeRootViewControllerInWindow:] + 180 27 UIKit 0x00265c1c -[UIWindow addRootViewControllerViewIfPossible] + 609 28 UIKit 0x00265d97 -[UIWindow _setHidden:forced:] + 312 29 UIKit 0x0026602d -[UIWindow _orderFrontWithoutMakingKey] + 49 30 UIKit 0x0027089a -[UIWindow makeKeyAndVisible] + 65 31 UIKit 0x00223cd0 -[UIApplication _callInitializationDelegatesForURL:payload:suspended:] + 1851 32 UIKit 0x002283a8 -[UIApplication _runWithURL:payload:launchOrientation:statusBarStyle:statusBarHidden:] + 824 33 UIKit 0x0023c87c -[UIApplication handleEvent:withNewEvent:] + 3447 34 UIKit 0x0023cde9 -[UIApplication sendEvent:] + 85 35 UIKit 0x0022a025 _UIApplicationHandleEvent + 736 36 GraphicsServices 0x036df2f6 _PurpleEventCallback + 776 37 GraphicsServices 0x036dee01 PurpleEventCallback + 46 38 CoreFoundation 0x016b3d65 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ + 53 39 CoreFoundation 0x016b3a9b __CFRunLoopDoSource1 + 523 40 CoreFoundation 0x016de77c __CFRunLoopRun + 2156 41 CoreFoundation 0x016ddac3 CFRunLoopRunSpecific + 467 42 CoreFoundation 0x016dd8db CFRunLoopRunInMode + 123 43 UIKit 0x00227add -[UIApplication _run] + 840 44 UIKit 0x00229d3b UIApplicationMain + 1225 45 Checklists 0x00001b7d main + 141 46 libdyld.dylib 0x01d7670d start + 1 ) libc++abi.dylib: terminating with uncaught exception of type NSException </code></pre> <p>PPS.
