我的班级对象有一个非常奇怪的问题，在一个区块a中有一个我的View Controller的弱引用，该区块中的部分代码是
__weak typeof(self) weakSelf = self;
[weakSelf performSelector:@selector(reloadItems) withObject:nil afterDelay:0];
[weakSelf.view setUserInteractionEnabled:YES];
if (weakSelf.shouldPresentNotification) {
[[LLAPI sharedInstance] presentLatestNotification];
weakSelf.shouldPresentNotification = NO;
}
问题是我的几个用户可能遇到过此次崩溃 [__NSCFNumber shouldPresentNotification]：无法识别的选择器发送到实例0xbb3c1937855f68da
现在，我知道崩溃报告告诉我，weakSelf是一个NSNumber对象，但这并没有任何意义，如果这是真的，为什么崩溃只会被提升到变量＆＃ 34; shouldPresentNotification＆＃34;被访问？
