我有保存在Documents目录中的jpg文件,可以从标准UIActivityViewController共享.所有活动项目(包括"保存图像")都按预期工作,但是当点击"保存图像"时,控制台中会显示以下错误,尽管事实上jpg确实已保存到相机胶卷.

这是iOS中的错误,还是我必须以某种方式指定我的文件是文件URL中的jpg(而不是视频)？

2015-07-29 06:46:58.317 AppName [4658:893408]视频/var/mobile/Containers/Data/Application/A63DF08E-21D0-435D-A0D7-84D73D632FC9/Documents/ImageStore/805/23.jpg无法保存到保存的相册:错误域= AVFoundationErrorDomain代码= -11828"无法打开"UserInfo = 0x1702e8b80 {NSLocalizedFailureReason =不支持此媒体格式.,NSLocalizedDescription =无法打开,NSURL = file:/// var/mobile/Containers /数据/应用/ A63DF08E-21D0-435D-A0D7-84D73D632FC9/Documents/ImageStore/805/23.jpg,NSUnderlyingError = 0x170c4f9f0"操作无法完成.(OSStatus error -12847.)"}

这是我正在使用的代码:

NSURL *fileURL = [NSURL fileURLWithPath: [...path to my file...] isDirectory:NO];
UIActivityViewController *activityViewController = [[UIActivityViewController    alloc] initWithActivityItems:@[fileURL] applicationActivities:nil];
activityViewController.excludedActivityTypes = @[UIActivityTypeCopyToPasteboard, UIActivityTypePrint, UIActivityTypeAssignToContact, UIActivityTypeAddToReadingList, UIActivityTypePostToVimeo];
[self presentViewController:activityViewController animated:YES completion:nil];

刚升级到XCode 8和我的设备到iOS 10,然后我第一次输入任何textField时收到此消息.

[MC] System group container for systemgroup.com.apple.configurationprofiles path is /private/var/containers/Shared/SystemGroup/systemgroup.com.apple.configurationprofiles

[MC] Reading from public effective user settings errors.

我的应用程序仍然可以运行,没有任何问题,但我想在提交之前摆脱这个警告.

我的应用程序是用Objective-C编写的,如果这有所不同的话.

我知道它来自键盘,因为我已经注释掉了进入textField时所采取的所有操作(实际上它是任何textField),并且仍然会出现错误.

有修复吗？如果没有,是否可以提交此警告？

当我使用以下代码时,我有错误消息:

[NSURLConnection sendAsynchronousRequest:request queue:myQueue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
        NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
        NSLog(@"response status code: %ld, error status : %@", (long)[httpResponse statusCode], error.description);

        if ((long)[httpResponse statusCode] >= 200 && (long)[httpResponse statusCode]< 400)
            {
               // do stuff
                [self requestFunction]; //Web Service
            }
}];

错误消息:

[self requestFunction]函数启动一个简单的请求:
