Hi I have a crash in the GetCell method in a custom UITableViewSource using de .dsym and the .crash files I get that error is lunched in the var item = tableItems [indexPath.Row]; instruction, the error is happening when I scroll to fast the UITableView this is my test code
public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath) { Console.WriteLine ("Here 1 "); var cell = tableView.DequeueReusableCell ("contactCellID") as ICTableContactCell; Console.WriteLine ("Here 1/2"); Console.WriteLine ("Here 2 "+(tableItems==null)); Console.WriteLine ("Here 2 "+(tableItems.Count)); Console.WriteLine ("Here 2 "+(indexPath==null)); Console.WriteLine ("Here 2 "+(indexPath.Row)); Console.WriteLine ("Here 2 "+(tableItems.Count)+" - "+(indexPath==null)+" "+(indexPath.Row)); var item = tableItems [indexPath.Row]; item.index = indexPath.Row; if (cell == null) { cell = new ICTableContactCell (item, new NSString ("contactCellID")); } cell.UpdateCell (item); return cell; } this the Xcode console output Feb 27 20:18:19 Developers-iPod CardReader_iOS[1767] <Warning>: here 1 Feb 27 20:18:19 Developers-iPod CardReader_iOS[1767] <Warning>: here 1/2 Feb 27 20:18:19 Developers-iPod CardReader_iOS[1767] <Warning>: here 2 False Feb 27 20:18:19 Developers-iPod CardReader_iOS[1767] <Warning>: here 2 659 Feb 27 20:18:19 Developers-iPod CardReader_iOS[1767] <Warning>: here 2 False Feb 27 20:18:19 Developers-iPod CardReader_iOS[1767] <Warning>: here 2 644 Feb 27 20:18:19 Developers-iPod CardReader_iOS[1767] <Warning>: here 2 659 - False 644 Feb 27 20:18:19 Developers-iPod CardReader_iOS[1767] <Warning>: here 1 Feb 27 20:18:19 Developers-iPod CardReader_iOS[1767] <Warning>: here 1/2 Feb 27 20:18:19 Developers-iPod CardReader_iOS[1767] <Warning>: here 2 False Feb 27 20:18:20 Developers-iPod CardReader_iOS[1767] <Warning>: here 2 659 Feb 27 20:18:20 Developers-iPod CardReader_iOS[1767] <Warning>: here 2 False Feb 27 20:18:20 Developers-iPod CardReader_iOS[1767] <Error>: Stacktrace: this is the symbolicate crash Date/Time: 2014-02-27 20:18:20.064 -0400 OS Version: iOS 7.0.4 (11B554a) Report Version: 104 Exception Type: EXC_BAD_ACCESS (SIGABRT) Exception Subtype: KERN_INVALID_ADDRESS at 0x00000000 Triggered by Thread: 0 Thread 0 Crashed: 0 libsystem_kernel.dylib 0x3a15d1fc __pthread_kill + 8 1 libsystem_pthread.dylib 0x3a1c6a2e pthread_kill + 54 2 libsystem_c.dylib 0x3a10dff8 abort + 72 3 CardReader_iOS 0x002f2674 mono_handle_native_sigsegv (mini-exceptions.c:2335) 4 CardReader_iOS 0x002fb508 mono_sigsegv_signal_handler (mini.c:6744) 5 libsystem_platform.dylib 0x3a1c1060 _sigtramp + 40 6 CardReader_iOS 0x00049b7c CardReader_iOS.ICTableContactSource:GetCell + 476 7 CardReader_iOS 0x001b8c50 ___lldb_unnamed_function9222$$CardReader_iOS + 196 8 CardReader_iOS 0x002fd5e4 mono_jit_runtime_invoke (mini.c:6610) 9 CardReader_iOS 0x00337b3a mono_runtime_invoke (object.c:2827) 10 CardReader_iOS 0x002ce1ca native_to_managed_trampoline_CardReader_iOS_ICTableContactSource_GetCell (registrar.m:828) 11 UIKit 0x3212ea56 -[UITableView _createPreparedCellForGlobalRow:withIndexPath:] + 406 12 UIKit 0x320d6e78 -[UITableView _updateVisibleCellsNow:] + 1800 13 UIKit 0x320d6694 -[UITableView layoutSubviews] + 180 14 UIKit 0x31ffcd9e -[UIView(CALayerDelegate) layoutSublayersOfLayer:] + 342 15 QuartzCore 0x31c83c66 -[CALayer layoutSublayers] + 138 16 QuartzCore 0x31c7f476 CA::Layer::layout_if_needed(CA::Transaction*) + 346 17 QuartzCore 0x31c7f308 CA::Layer::layout_and_display_if_needed(CA::Transaction*) + 12 18 QuartzCore 0x31c7ed1a CA::Context::commit_transaction(CA::Transaction*) + 226 19 QuartzCore 0x31c7eb2a CA::Transaction::commit() + 310 20 QuartzCore 0x31cd3820 CA::Display::DisplayLink::dispatch_items(unsigned long long, unsigned long long, unsigned long long) + 512 21 IOMobileFramebuffer 0x348c976a IOMobileFramebufferVsyncNotifyFunc + 102 22 IOKit 0x3056ba72 IODispatchCalloutFromCFMessage + 246 23 CoreFoundation 0x2f849e1e __CFMachPortPerform + 134 24 CoreFoundation 0x2f8549dc __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ + 32 25 CoreFoundation 0x2f854976 __CFRunLoopDoSource1 + 342 26 CoreFoundation 0x2f85314a __CFRunLoopRun + 1394 27 CoreFoundation 0x2f7bdc22 CFRunLoopRunSpecific + 518 28 CoreFoundation 0x2f7bda06 CFRunLoopRunInMode + 102 29 GraphicsServices 0x344ad27e GSEventRunModal + 134 30 UIKit 0x32061044 UIApplicationMain + 1132 31 CardReader_iOS 0x000ac868 (wrapper managed-to-native) MonoTouch.UIKit.UIApplication:UIApplicationMain + 268 32 CardReader_iOS 0x00088a94 MonoTouch.UIKit.UIApplication:Main (.pmcs-compat.UIApplication.cs:75) 33 CardReader_iOS 0x0003a05c CardReader_iOS.Application:Main + 44 34 CardReader_iOS 0x001b8c50 ___lldb_unnamed_function9222$$CardReader_iOS + 196 35 CardReader_iOS 0x002fd5e4 mono_jit_runtime_invoke (mini.c:6610) 36 CardReader_iOS 0x00337b3a mono_runtime_invoke (object.c:2827) 37 CardReader_iOS 0x0033b6c0 mono_runtime_exec_main (object.c:4052) 38 CardReader_iOS 0x0033b510 mono_runtime_run_main (object.c:3678) 39 CardReader_iOS 0x002ebdac mono_jit_exec (driver.g.c:1009) 40 CardReader_iOS 0x0036e060 main (main.m:489) 41 libdyld.dylib 0x3a0a6ab4 start + 0 -- View this message in context: http://monotouch.2284126.n4.nabble.com/indexPath-Row-in-UITableViewSource-Get-Cell-crash-the-app-tp4658552.html Sent from the MonoTouch mailing list archive at Nabble.com. _______________________________________________ MonoTouch mailing list MonoTouch@lists.ximian.com http://lists.ximian.com/mailman/listinfo/monotouch
