How to find a file in Project? - ios

I'm getting a problem to find a file from project. I am getting this file using code but I can't get it using url.
Please help me out from this problem.
Here is the path of file
Users/yatish/Library/Developer/CoreSimulator/Devices/65048208-DC46-4B30-9526-470D6D8081D3/data/Containers/Data/Application/2E7EFDA0-9C0C-4440-962D-610C2AC18DDD/Documents/file.txt
Here is the code
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *Path = [NSString stringWithFormat:#"%#/%#%#",documentsDirectory,#"file"#".txt"];
[str writeToFile:Path atomically:YES encoding:NSUTF8StringEncoding error:&error];
NSString *fn=#"file";
NSString *searchFilename =[fn stringByAppendingString:#".txt"]; // name of the PDF you are searching for
NSArray *pathss = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectorys = [pathss objectAtIndex:0];
NSDirectoryEnumerator *direnum = [[NSFileManager defaultManager] enumeratorAtPath:documentsDirectorys];
NSString *documentsSubpath;
BOOL fileFound = false;
while (documentsSubpath = [direnum nextObject])
{
if (![documentsSubpath.lastPathComponent isEqual:searchFilename]) {
continue;
fileFound=NO;
}
NSLog(#"found %#", documentsSubpath);
fileFound =YES;
}
if(fileFound){
NSLog(#"File Found");///this line is execute when i run this code
}

In code, you can use:
NSURL *fileURL = [NSURL URLWithPath: documentsSubpath];
And that will be the path to your file.
If you want to see the actual file, go to the Macintosh Finder and click "Go To Folder" (it's under the "Go" menu, or ⇧⌘G all together). Then type in your path MINUS the last path component, which is the filename. In your case, that is "/Users/yatish/Library/Developer/CoreSimulator/Devices/65048208-DC46-4B30-9526-470D6D8081D3/data/Containers/Data/Application/2E7EFDA0-9C0C-4440-962D-610C2AC18DDD/Documents".

Files added to documents directory shows up in Simulator but nothing in iphone

This is the code I'm using and it works in simulator but showing nothing in idevice. If I add an folder or a file through ifunbox it shows up in device though. Do I need any permission to create or add files?
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat: #"/Folders/%#", self.txtFolder.text]];
NSLog(#"%#", dataPath);
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
{
[[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder
[sec1Contents addObject:self.txtFolder.text];
sec1 = [NSArray arrayWithArray:sec1Contents];
[self.tblFiles reloadData];
}
thanks in advance.
Use this code :
NSURL *allitemsImageurl =[NSURL URLWithString: url];
NSData *allItemsImageData = data1; // Load XML data from web
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * documentsDirectoryPath = [paths objectAtIndex:0];
NSString *st1=[ #"img_" stringByAppendingString:[NSString stringWithFormat:#"%d.png",imageCount]];
NSString *allitemsImagePath = [documentsDirectoryPath stringByAppendingPathComponent:st1];
NSLog(#"%#",allitemsImagePath);
[allItemsImageData writeToFile:allitemsImagePath atomically:TRUE];

How can i do that?
Get all the contents in the folder
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSArray *fileList = [[NSFileManager defaultManager] directoryContentsAtPath:documentsDirectory];
Enumerate over the files list and check if it constains .txt
[fileList enumerateObjectsUsingBlock:^(NSString *string, NSUInteger index, BOOL *stop) {
if ([string hasSuffix:#".txt"]) {
[[NSFileManager defaultManager]copyItemAtPath:strdestination toPath:toPath error:&Error];
}
}];
Update
Updated my answer according to comments by Martin R
Update 2
As pointed out by Hot Licks use
if ([[string pathExtension] isEqualToString:#"txt"]) {
To check for the file extension.

How to copy text file from document directory in iOS

Hello i am trying to copy text file from document directory into folder name Temp that located in document directory.
Here is some of code i tried and didn't work.
self.fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *documentsDirectoryToTemp = [NSString stringWithFormat:#"%#/Temp/",[paths objectAtIndex:0]];
NSString *txtPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.txt",tblGetNameToMove.textLabel.text]];
[self.fileManager copyItemAtPath:txtPath toPath:documentsDirectoryToTemp error:&error];
How can i do that?
There could be many reasons for this :
First try to print all the path like documentsDirectoryToTempn and txtPath whether it is correct or not .
The second thing is make use that error variable :
if(error)
{
NSLog("Error while coping :%#",[error localizedDiscription]);
}
so you can track exact problem .
Here is solution. I need to add directory and also name of file and extension.
Here is codes.
self.fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *txtPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.txt",tblGetNameToMove.textLabel.text]];
NSString *fileName = [NSString stringWithFormat:#"%#/Temp/%#.txt",documentsDirectory,tblGetNameToMove.textLabel.text];
[self.fileManager copyItemAtPath:txtPath toPath:fileName error:&error];

NSKeyedArchiver archiveRootObject keeps returning NO

I've spent the past few hours trying to figure this out, but I've ran out of ideas.
All I'm trying to do is archive an object, but the method archiveRootObject keeps on returning NO
Here's my code:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *cacheDirectory = [paths objectAtIndex:0];
cacheDirectory = [cacheDirectory stringByAppendingPathComponent:#"MyAppCache"];
NSString *fullPath = [cacheDirectory stringByAppendingPathComponent:#"archive.data"];
if(![[NSFileManager defaultManager] fileExistsAtPath:fullPath]){
[[NSFileManager defaultManager] createDirectoryAtPath:fullPath withIntermediateDirectories:YES attributes:nil error:nil];
}
NSArray *array = [NSArray arrayWithObjects:#"hello", #"world", nil];
NSLog(#"Full Path: %#", fullPath);
BOOL res = [NSKeyedArchiver archiveRootObject:array toFile:fullPath];
if(res){
NSLog(#"YES");
}else{
NSLog(#"NO");
}
Every time time I run this, it prints NO.
Any help would be appreciated!
You create a directory with the path fullPath and then you try to write the file at the same path. Overwriting a directory with a file like this is not possible. Use your cacheDirectory string to create your directory.
NSString *cacheDirectory is not a mutable string and after you init it, you attempt to modify it so you are writing to the top-level directory.
For a quick fix, try:
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *documentPath = ([documentPaths count] > 0) ? [documentPaths objectAtIndex:0] : nil;
NSString *documentsResourcesPath = [documentPath stringByAppendingPathComponent:#"MyAppCache"];
NSString *fullPath = [documentsResourcesPath stringByAppendingPathComponent:#"archive.data"];
