nsfilemanager

I cannot get the NSFileManager method replaceItemAtURL:withItemAtURL:backupItemName:options:resultingItemURL:error: to work in iOS 6. Apps that call this method and worked fine on iOS 5 have major issues on iOS 6. The problem does not occur on devices running versions of iOS below 6.0. The problem does not occur if the app is launched in the iOS Simulator by Xcode. Otherwise the problem seems to be universal. Here is the test code I am trying to execute: NSError *error; NSFileManager *fileManager = [NSFileManager defaultManager]; NSString *documentsDirectory =

After reading Apple documentation , I used URLsForDirectory to obtain the Library destination within my app, and my objective is to download content from a hosted service & cache it in the Library folder, so that User cannot interact with the contents through iTunes. NSArray *docPaths= [[NSFileManager defaultManager] URLsForDirectory:NSLibraryDirectory inDomains:NSUserDomainMask]; NSLog(@"%@",[docPaths description]); NSString *docPath=[(NSURL *)[docPaths objectAtIndex:0] path]; docPath = [docPath stringByAppendingPathComponent:@"audios"]; Running & executing the code several times(various

Thanks to a variety of helpful posts in this forum, I have some code that works for obtaining the Creation Date of a single user-selected NSURL. However, I cannot get the code to work for either a hard-coded NSURL, nor within a loop through an NSFileManager enumerator. I am not a professional programmer; I make apps that are tools for office. My ultimate goal is to simply sort an Array of NSURL objects based on Creation Date. The code I am using is below, which functions just fine as is, but if I try to use the commented line to evaluate a specific PDF file, I get the following error: I get

I try to call the fileManager.createFileAtPath -method, but it always fails. My variable success is always false . I looked at some similar posts here but nothing fits my needs exactly. Here is my code: pListPath = NSURL(fileURLWithPath: String(reportsPath)).URLByAppendingPathComponent("myReports.plist", isDirectory: false) let data: NSData = NSData() var isDir: ObjCBool = false if fileManager.fileExistsAtPath(String(pListPath), isDirectory: &isDir) { print("File already exists") } else { let success = fileManager.createFileAtPath(String(pListPath), contents: data, attributes: nil) print("Was

Say I've got a folder in my iOS app's data directory with several thousand small files in it. Deleting this folder (via [NSFileManager removeItemAtPath] ) takes a nontrivial amount of time. But on OS X, deleting a folder with the same contents is very fast. It seems to simply unlink the folder from the filesystem. So why does iOS take so long? What is the difference? Edit: On an iPad 3, deleting 3 folders with 5,000 to 9,000 files each takes about 35 seconds. On the simulator running on an older Retina MBP, it takes about 1.5 seconds. Harsh The hierarchical structure that you see is not "real"

I am making two iPad app that communicate with one file and fetches all the data from one file. I search and find this "containerURLForSecurityApplicationGroupIdentifier" we can create group and store in that. I have write the code below. In entitlement file i write <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.security.app-sandbox</key> <true/> <key>com.apple.security.application-groups</key> <array> <string>$(TeamIdentifierPrefix)com.xxx.catalogapp

My app will write some files to file system and it is installed in /Application not in /var/mobile/Application, On my develop iPhone, every things goes right.But when distribute to others, They got "Cocoa error 513".The files are written at /var/mydir/files, What's that problem? Where is right place for me to write with full permission? Thank you. Code: NSString *dir = @"/var/mydir/docs/"; NSFileManager *fileManager = [NSFileManager defaultManager]; if(![fileManager fileExistsAtPath:dir]) { NSError *error = nil; BOOL createdDir = [fileManager createDirectoryAtPath:dir
