我在我们的应用程序中每1000到2000次会话中发生一次崩溃,我无法弄清楚该怎么做.

这是Apple iOS崩溃,我无法做任何事情吗？

我在我的项目中使用SDWebImage pod,也许就是这样？

这是崩溃日志:

我有一次罕见的崩溃，我认为它发生在用户尝试共享照片时，同样非常罕见，10,000 个会话中有 1 个崩溃。如果有人可以提供有关它可以是什么的任何信息，我会很高兴吗？

谢谢！

我已经看过iOS的iCloud Document示例代码,我用它来同步iCloud 的uidocument,现在我试图在没有的Mac OSX应用程序上同步iCloud和nsdocumentUIDocument.

我试图改变UIDocument,NSDocument但与icloud同步的所有方法都不同.我没有找到任何示例代码或教程,除了苹果的文档,这是非常令人困惑和写得不好.

例如,OS X上UIDocument不存在iOS上的以下方法NSDocument:

//doc is an instance of subclassed UIDocument
[doc openWithCompletionHandler:nil];

Apple文档为OS X提供此代码:

- (void)checkIfCloudAvaliable {
    NSURL *ubiquityContainerURL = [[[NSFileManager defaultManager]
                                    URLForUbiquityContainerIdentifier:nil]
                                   URLByAppendingPathComponent:@"Documents"];
    if (ubiquityContainerURL == nil) {
        NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:
                              NSLocalizedString(@"iCloud does not appear to be configured.", @""),
                              NSLocalizedFailureReasonErrorKey, nil];
        NSError *error = [NSError errorWithDomain:@"Application" code:404
                                         userInfo:dict];
        [self presentError:error modalForWindow:[self windowForSheet] delegate:nil
        didPresentSelector:NULL contextInfo:NULL];
        return; …

我没有找到一种没有相机界面拍照的简单方法.我只需要从相机中获取一张照片并将其保存到文件中.
