nsfilemanager

As I need to read a file when my app is launched and write it sometimes while using it, I tried to reach it with : NSString *dataFile = [[NSBundle mainBundle] pathForResource:@"data" ofType:@"txt"]; NSLog(@"%@",dataFile); And the file, that should be in my project folder, is instead in the simulator folder : 2012-06-13 17:36:56.398 MyFileApp[610:15203] /Users/Rob/Library/Application Support/iPhone Simulator/5.1/Applications/1FFD4436-DCCA-4280-9E47-F6474BEE0183/MyFileApp.app/myFile.txt So if I want to read/write it in using the simulator as well as the real device, what should I do ? Thanks for

I am saving files in a document directory in swift 3 with this code: fileManager = FileManager.default // let documentDirectory = fileManager?.urls(for: .documentDirectory, in: .userDomainMask).first as String var path = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)[0] as String path = path + name let image = #imageLiteral(resourceName: "Notifications") let imageData = UIImageJPEGRepresentation(image, 0.5) let bool = fileManager?.createFile(atPath: path, contents: imageData, attributes: nil) print("bool is \(bool)") return true But as you can see, I am not

I have a NSURL object. It has address of a filesystem element, it is either a file or a directory. I want to be able to tell if the NSURL is a directory or a file. I have already tried this, which doesn"t seem to work! NSURL * temp ....... ;// it is initialized and has a valid value CFURLRef xx = (CFURLRef)CFBridgingRetain(temp); if(CFURLHasDirectoryPath(xx)) NSLog(@"was a file"); else NSLog(@"was a folder"); NSNumber *isDirectory; // this method allows us to get more information about an URL. // We're passing NSURLIsDirectoryKey as key because that's the info we want to know. // Also, we pass

I guess this is a beginner's problem, but I was trying to check if a directory exists in my Documents folder on the iPhone. I read the documentation and came up with this code which unfortunately crashed with EXC_BAD_ACCESS in the BOOL fileExists line: -(void)checkIfDirectoryAlreadyExists:(NSString *)name { NSFileManager *fileManager = [[NSFileManager alloc] init]; NSString *path = [[self documentsDirectory] stringByAppendingPathComponent:name]; BOOL fileExists = [fileManager fileExistsAtPath:path isDirectory:YES]; if (fileExists) { NSLog(@"Folder already exists..."); } } I don't understand

It appears after much searching that there seems to be a common problem when trying to do a file copy and show a progress indicator relative to the amount of the file that has been copied. After spending some considerable time trying to resolve this issue, I find myself at the mercy of the StackOverflow Gods once again :-) - Hopefully one day I'll be among those that can help out the rookies too! I am trying to get a progress bar to show the status of a copy process and once the copy process has finished, call a Cocoa method. The challenge - I need to make use of File Manager Carbon calls

In my application I download PDF files which gets stored in "Document" directory under different sub folders. Now I have file name for which I want to get its path in "Document" directory but problem is I don't know the exact sub folder under which that file is stored. So is there any method which will give me file path by file's name like there is one method which works for main bundle: (NSString *)pathForResource:(NSString *)name ofType:(NSString *)extension I don't want to iterate through each folder which is a tedious way. Thanks. Abhi Beckert You can search the documents directory like

I want to quickly check to see if a file exists in my iPhone app's Documents directory (or any path for that matter). I can enumerate through the directory's files, or I can try to open a specific file. What's the fastest way? I just need to know if the file is there or if it does not exist. rein Swift v3: let fileExists = FileManager.default.fileExists(atPath: somePath) Thanks to Nikolay Suvandzhiev . Objective-C (Original): BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:somePath]; 来源： https://stackoverflow.com/questions/1356701/whats-a-quick-way-to-test-to-see-a-file
