应用程序崩溃iPhone 5s ios 7.1.1

时间:2014-05-08 12:41:18

标签: iphone ios7 crash

我将我的应用提交到应用商店,5天后他们拒绝了。他们告诉我该应用程序在运行iOS 7.1.1的7.1.1 iPhone 5上崩溃。

库AFNetworking上有问题吗?

感谢您的帮助。

这是崩溃报告:

来自Apple文档:

@property(nonatomic) AVCaptureFlashMode flashMode

Discussion
Before changing the value of this property, 
you must call lockForConfiguration: 
to acquire exclusive access to the device’s configuration properties. 
Otherwise, setting the value of this property raises an exception. 
When you are done configuring the device, call unlockForConfiguration 
to release the lock and allow other devices to configure the settings.

这就是崩溃的原因,您需要获得独家访问权限。

所以只需添加:

if ([device isFlashModeSupported:AVCaptureFlashModeOff) {
    NSError *error;
    if ([device lockForConfiguration:&error) {
        //It's now safe to add your original code here....
        [device setFlashMode:AVCaptureFlashModeOff]; 
    }

    else 
        NSLog(@"ERROR: %@", [error localizedDescription]);
}

这样一来,如果有一个原因导致应用程序无法锁定您想要的闪光模式,您将收到错误消息。它也会跳过它,因此它不会引发异常&崩溃。
