Question

我已经在网上搜索了很多关于这个问题但是我还没有设法解决它，所以不得不转而发布这个问题。

我在我的应用中使用浮动按钮;我通过Cocoapods将库包含在我的Podfile中。 Pod库是MVFloatingButton＆＃39;。应用程序工作正常，直到我添加浮动按钮。

请在TableView上找到浮动按钮的屏幕截图（在iOS模拟器中运行）

我遇到的问题是我的TableView。浮动按钮在tableView上显示正常但是当我导航回主屏幕时，我的应用程序崩溃并出现以下错误：

*由于未捕获的异常而终止应用程序＆＃39; NSInternalInconsistencyException＆＃39;，原因：＆＃39;类UITableView的实例0x7a8a5000已取消分配，而键值观察者仍在其中注册。目前的观察资料:( 上下文：0x0，属性：0x79f91d10＆gt; 上下文：0x0，属性：0x79f92bf0＆gt; 上下文：0x0，属性：0x79f93000＆gt; ）＆＃39; * 第一次抛出调用堆栈：（ 0 CoreFoundation 0x036a1494 __exceptionPreprocess + 180 1 libobjc.A.dylib 0x0315be02 objc_exception_throw + 50 2 CoreFoundation 0x036a13bd + [NSException raise：format：] + 141 3基础0x02d94097 NSKVODeallocate + 353 4 UIKit 0x020cf348 - [UIView（UIKitManual）发布] + 142 5 libobjc.A.dylib 0x0316e34f objc_release + 47 6 libobjc.A.dylib 0x0316f52d _ZN12_GLOBAL__N_119AutoreleasePoolPage3popEPv + 371 7 CoreFoundation 0x035718a8 _CFAutoreleasePoolPop + 24 8 CoreFoundation 0x035a943c __CFRunLoopRun + 2364 9 CoreFoundation 0x035a8846 CFRunLoopRunSpecific + 470 10 CoreFoundation 0x035a865b CFRunLoopRunInMode + 123 11 GraphicsServices 0x0662a664 GSEventRunModal + 192 12 GraphicsServices 0x0662a4a1 GSEventRun + 104 13 UIKit 0x017dfeb9 UIApplicationMain + 160 14 NHSF 0x00096afa main + 138 15 libdyld.dylib 0x04865a25 start + 1 ） libc ++ abi.dylib：以NSException类型的未捕获异常终止

据我所知，我认为这与＆＃39; dequeueReusableCellWithIithntifier＆＃39; 有关，但我并非百分百肯定。

这是我的.h文件：

#import <UIKit/UIKit.h>

@interface NHSFAdminTeamTableViewController : UITableViewController

@property (strong, nonatomic) NSMutableArray *jsonArray;
@property (strong, nonatomic) NSMutableArray *AdminArray;


#pragma mark - Class Method
-(void)retrieveData;

- (void)floatingButtonDidDisappear:(UIScrollView *)scrollView;
//3.0 --

@end

任何帮助都会有很大的帮助！谢谢！
