_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。 https://github.com/ibireme/YYText/issues/842 https://github.com/ibireme/YYText/issues/924

这个有解决方法吗？

我用分类覆盖了他有问题的地方

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)

• (void)_initFrameObserver { UIView keyboardView = self.keyboardView; if (!keyboardView) { return; } UIView lastKeyboard = [[self weakPropertyMap] objectForKey:@"keyboardView"]; if(lastKeyboard == keyboardView) { return; } [[self weakPropertyMap] setObject:keyboardView forKey:@"keyboardView"]; weak typeof(self) weakSelf = self; weak UIView *weakKeyboardView = keyboardView; SEL sel = NSSelectorFromString(@"_keyboardFrameChanged:"); void(^block)(id x) = ^(id x) { if(weakKeyboardView && [weakSelf respondsToSelector:sel]) {

  pragma clang diagnostic push

      #pragma clang diagnostic ignored "-Warc-performSelector-leaks"
          [weakSelf performSelector:sel withObject:weakKeyboardView];
      #pragma clang diagnostic pop

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?
