iphone - 应用程序在 iPhone 5 6.1.4 上崩溃，但在其他版本上运行良好

Question

我正在提交我的第一个应用程序，所以我肯定仍在学习很多东西。我刚刚收到应用拒绝通知，我的应用:

我们发现您的应用在运行 iOS 6.1.4 的 iPhone 5 上崩溃当闹钟应该响起时，您的应用程序崩溃了。

使用您的应用时会发生这种情况:

• 通过 Wi-Fi
• 通过蜂窝网络

我在这里附上了崩溃报告，我希望有人能够帮助我解决这个问题!它在所有其他版本上都运行良好，不幸的是我没有 iPhone5 6.1.4 来测试它，所以从来没有注意到它!思考是否与 CFRunLoop 有关？

谢谢!

这是崩溃前我的代码中的最后一个方法:

-(void)torch:(BOOL)isOn { 
    torchIsOn = isOn; 
    [self strobeOff]; 
    [device lockForConfiguration:nil]; 
    if (isOn) { 
        [slider setHidden:NO]; 
        [device setTorchModeOnWithLevel:[slider value] error:nil]; 
        [slider addTarget:self action:@selector(torch:) forControlEvents:UIControlEventValueChanged]; 
    }
    else { 
        [device setTorchMode:NO]; 
    } 

    [device unlockForConfiguration]; 
}

Answer 1

在设置手电筒模式之前，请尝试在 torch: 方法中进行这些检查。

[设备 hasTorch] 和 [设备 torchAvailable] 和 [设备 isTorchModeSupported:AVCaptureTorchModeOn]

手电筒可能无法使用。这可能会导致崩溃。请注意，[device torchAvailable] 适用于 iOS 5 及更高版本。

来自 AVCaptureDevice class reference :

Even if the device has a torch, that torch might not be available for use. Thus, you should also check the value of the torchAvailable property before using it.

所以你的 torch: 方法可能看起来像:

-(void)torch:(BOOL)isOn { 
    torchIsOn = isOn; 
    [self strobeOff]; 
    [device lockForConfiguration:nil]; 

    if (isOn && [device hasTorch] && [device torchAvailable] && [device isTorchModeSupported:AVCaptureTorchModeOn]) { 
        [slider setHidden:NO]; 
        [device setTorchModeOnWithLevel:[slider value] error:nil]; 
        [slider addTarget:self action:@selector(torch:) forControlEvents:UIControlEventValueChanged]; 
    }
    else { 
        [device setTorchMode:NO]; 
    } 

    [device unlockForConfiguration]; 
}
