UITableView被解除分配，而键值观察者仍在其中注册，只是在iOS9和iOS10中崩溃

我在解除锁定时移除了所有的障碍，但我看起来崩溃似乎并没有移除成功，我不知道为什么，每个人都可以帮助我

@interface SYDiagnoseFloatingView()

@property (nonatomic, strong) UIImageView *imageView;

@property (nonatomic, strong) NSMutableArray<UIScrollView *> *scrollViews;

@end

@implementation SYDiagnoseFloatingView

这是我的代码和崩溃信息。我不知道我的代码出了什么问题，谁能帮我

@interface SYDiagnoseFloatingView()

@property (nonatomic, strong) UIImageView *imageView;

@property (nonatomic, strong) NSMutableArray<UIScrollView *> *scrollViews;

@end

@implementation SYDiagnoseFloatingView

添加观察者

- (void)addFloatingTargetView:(UIScrollView *)scrollView {
    if ([self.scrollViews containsObject:scrollView]) {
        return;
    }
    [self.scrollViews addObject:scrollView];
    [scrollView addObserver:self forKeyPath:keypath options:NSKeyValueObservingOptionNew|NSKeyValueObservingOptionOld context:nil];
}

我认为您添加了两次相同的观察者。始终调用

[scrollView removeObserver:self-forKeyPath:keypath上下文：nil]

；

[scrollView addObserver:self-forKeyPath:keypath选项：NSKeyValueObservingOptionNew | NSKeyValueObservingOptionOld上下文：nil]之前

如何添加观察者？我已将代码添加到问题中，请查看您在主线程调用中调用
addFloatingTargetView:
