iCloudを統合しようとしています。
すべて正常に動作しますが、iCloud からファイルを読み取ろうとすると、次のような警告が表示されます。
Foundation called mkdir("/var/mobile/Library/Mobile Documents/.ubd/peer-E8A60A8F-FB9D-8721-F47C-hdffgdfg-v23/ftr/(A Document Being Saved By XYZ)"), it didn't return 0, and errno was set to 1.
データを取得するための私のコード:
for (NSMetadataItem *item in results)
{
NSString *filename = [item valueForAttribute:NSMetadataItemDisplayNameKey];
NSURL *url = [item valueForAttribute:NSMetadataItemURLKey];
MyDocument *doc = [[MyDocument alloc] initWithFileURL:url];
[doc openWithCompletionHandler:^(BOOL success) {
if (success) {
NSData *file = [NSData dataWithContentsOfURL:url];
NSString *docDir = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"Import/iCloud"];
if (![[NSFileManager defaultManager] fileExistsAtPath:docDir])
[[NSFileManager defaultManager] createDirectoryAtPath:docDir withIntermediateDirectories:YES attributes:nil error:nil];
NSString *pdfFile = [docDir stringByAppendingPathComponent:filename];
if(![[NSFileManager defaultManager] fileExistsAtPath:pdfFile])
[[NSFileManager defaultManager] createFileAtPath:pdfFile contents:file attributes:nil];
NSLog(@"Successfully loaded data from cloud file name %@", filename);
}
else
{
NSLog(@"Failed to load data");
}
}];
}
}
