我有一个只在 IOS 7 中发生的崩溃，我无法重现它，但它经常发生。有人有答案吗，或者至少知道问题出在哪里。我已经删除了有关 ios7 的所有警告，但仍然发生崩溃。附上日志。

【问题讨论】：

这里一样，有时它会在 Foundation 或 UIKit 上崩溃
你知道导致这个崩溃的原因吗？
不，希望这篇文章能收集到答案
我遇到了同样的问题。奇怪的是它只出现在3.5英寸设备（ip4、ip4S）、os7.x中。在 ip5 上工作正常我尝试了很多方法但仍然无法修复错误

我遇到了同样的问题。奇怪的是它只出现在3.5英寸设备（ip4、ip4S）、os7.x中。在 ip5 上运行良好。

更新：我们的团队找到了根本原因。这是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;
            }];

为了修复这个错误，我们避免在 iOS

 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！

感谢曾经回复过的人。我通过在弹出视图控制器之前移除键盘（resignFirstResponder）解决了这个问题。

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），当弹出视图控制器时可能出了问题。

希望这会对某人有所帮助。

【解决方案3】：

我也遇到过类似的崩溃，但它发生在我在网络回调中创建的 UIView 上执行 removeFromSuperview 时。 [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 ) )

似乎在此回调中创建的任何视图在从超级视图中删除时都会崩溃 - 大多数情况下。

每当我在回调内部进行任何 UIView 更改时，我最终都会使用它。

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

在循环定时器回调中也发生了同样的情况

CFRunLoopAddTimer( CFRunLoopGetMain(), timeoutTimer, kCFRunLoopCommonModes);
