Foundation -[NSConcreteMapTable assign:key:value:isNew:] 崩溃：com.apple.main-thread EXC_BAD_ACCESS KERN_INVALID_ADDRESS 在

Question

我有一个崩溃只发生在 IOS 7，我无法重现它，但它发生了很多次。有人有答案或至少知道问题出在哪里吗？我已经删除了所有关于 ios7 的警告，但崩溃仍然发生。附上日志。

Answer 1

我遇到了类似的崩溃，只是当我对在网络回调中创建的 UIView 执行 removeFromSuperview 时发生。 [NSISEngine withBehaviors:performModifications:] 是在 removeFromSuperview

之后开始出错的地方

例如。里面 handleReadStreamEvent

if (!CFReadStreamSetClient( inputStream, kCFStreamEventHasBytesAvailable | kCFStreamEventErrorOccurred | kCFStreamEventEndEncountered | kCFStreamEventOpenCompleted
                           , handleReadStreamEvent, &context ) )

大多数情况下，似乎在此回调中创建的任何视图在从父视图中删除时都会崩溃。

每当我在回调中进行任何 UIView 更改时，我最终都会使用它。

- (void)performSelector:(SEL)aSelector withObject:(id)anArgument afterDelay:(NSTimeInterval)delay;

在循环计时器回调中发生同样的情况

CFRunLoopAddTimer( CFRunLoopGetMain(), timeoutTimer, kCFRunLoopCommonModes);

Answer 2

我遇到了同样的问题。奇怪的是它只出现在3.5inch设备（ip4，ip4S），os7.x。在 ip5 上工作正常。

更新：我们的团队找到了根本原因。因为我们在代码中使用了这个动画

[UIView animateWithDuration:0.4f delay:0 usingSpringWithDamping:0.5f initialSpringVelocity:0.3f options:UIViewAnimationOptionCurveEaseOut animations:^{
                self.transform = CGAffineTransformMakeScale(sx,sy);
            } completion:^(BOOL finished) {
                self.hidden = !visible;
            }];

为了修复错误，如果 iOS <8.0

，我们会避免运行动画

 if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_7_1) {
        [UIView animateWithDuration:0.4f delay:0 usingSpringWithDamping:0.5f initialSpringVelocity:0.3f options:UIViewAnimationOptionCurveEaseOut animations:^{
            self.transform = CGAffineTransformMakeScale(sx,sy);
        } completion:^(BOOL finished) {
            if (finished) {
                self.hidden = !visible;
            }
        }];
    } else {
        self.transform = CGAffineTransformMakeScale(sx,sy);
        self.hidden = !visible;
    }

希望对您有所帮助！

Answer 3

感谢您的回复。我通过在弹出视图控制器之前移除键盘 (resignFirstResponder) 来解决它。

在那个屏幕上，我有 2 个文本字段，其中一个连接到键盘（inpuAccessoryView），另一个刚刚激活第一个（我正在开发聊天），弹出视图控制器时可能出了点问题。

希望这会对某人有所帮助。
