_YYTextKeyboardViewFrameObserver崩溃

[zhazhaYang]

__unsafe_unretained UIView *_keyboardView;

推测：_keyboardView在_YYTextKeyboardViewFrameObserver对象dealloc前被释放掉了，导致访问了野指针。很可能两者的关联处理有关系。
场景：并未使用YY相关组件，而是使用了UITextField，调起了键盘。YYTextKeyboardManager单例收到了UIKeyboardDidChangeFrameNotification通知，最后导致的崩溃。

查了issues似乎有两个相关问题，麻烦看看呢。

这个有解决方法吗？

哈喽，能分享一下你的处理方案吗，我也遇到这个问题了

@implementation YYTextKeyboardManager (Helper)

哈哈，好惭愧，我是这么解决的，
@implementation YYTextKeyboardManager (FixCrash)

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wobjc-protocol-method-implementation"

• (instancetype)defaultManager {
  static YYTextKeyboardManager *mgr = nil;
  static dispatch_once_t onceToken;
  dispatch_once(&onceToken, ^{
  if (![UIApplication isAppExtension]) {
  mgr = [[self alloc] _initWithFixCrash];
  }
  });
  return mgr;
  }
  #pragma clang diagnostic pop

• (instancetype)_initWithFixCrash {
  self = [super init];
  return self;
  }

weakPropertyMap 这个实现方法是啥呀?
