Question

当用户轻按标记（GMSMapVIew：didTapMarker）时，我的应用程序崩溃了，而myApp在99％的时间内运行良好，但有时它在crashlytics上崩溃了。而且它是如此随机发生。

崩溃报告显示以下内容。

Crashed: com.apple.main-thread
EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x00000002f6ce97f4

下面是我的代码，其中应用程序崩溃。

BadgerMapView.m：1784

if（！[waypt isKindOfClass：[NSNull class]]）This is the line where i got crash

                        [mapViewController showMarkerSelectedAtMiddle:waypt];

                [waypt release];
                waypt = nil;
                break;


            }
        }
    } @catch (NSException *exception) {
        NSLog(@"Exception in ProcessdidTapMarker: %@",exception);
        [DeviceLoger log:[NSString stringWithFormat:@"Exception in ProcessdidTapMarker: %@",exception]];
    }
 }
   return YES;
}

有人有主意吗？

请帮助我，因为我面临这个问题的时间很长

谢谢！
