Problem writing string to a file ...(iPhone SDK ) - iphone

Question

I want to grab all URL's accessed in webview and write them to a text file.I don't want to use writeToFile coz in -(BOOL)webView method it would overwrite instead of appending to file. I can create file but all it writes to that file is string I used to create the file using FileManager createFileAtPath with Content ...
Also in the -(BOOL) webView method... when I tried to see if the file is read-only or writable ( isWritableFileAtPath ) it gives read-only.
POSIX Permissions in viewDidLoad -> 511 ...
checked file attributes in terminal going to that location its -rwxrwxrwx
I am new to Stack Overflow don't know how to post code here so using pastebin...http://pastebin.com/Tx7CsXVB
- (void)viewDidLoad {
[super viewDidLoad];
[myBrowser loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.apple.com"]]]; // UIWebView *myBrowser; is an instance variable
NSFileManager *fileMgr=[NSFileManager defaultManager];
NSDictionary* fileAttrs = [NSDictionary dictionaryWithObject:[NSNumber numberWithInteger:777] forKey:NSFilePosixPermissions]; /*for setting attribute to rwx for all users */
NSDictionary *attribs; // To read attributes after writing something to file
NSString *aPath = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/file1.txt"];
myBrowser.delegate = self; // UIWebView delegate Self
// if the File Doesn't exist create one
if([fileMgr fileExistsAtPath:aPath])
{
NSLog(#"File Exists at this Location");
}
else
{
NSString *someString = #"This is start of file";
NSData *startString =[someString dataUsingEncoding: NSASCIIStringEncoding];
[fileMgr createFileAtPath:aPath contents:startString attributes: fileAttrs]; // earlier attributes was nil changed to fileAttrs
}
NSLog(#"aPath is %#",aPath);
attribs = [fileMgr attributesOfItemAtPath:aPath error: NULL];
NSLog (#"Created on %#", [attribs objectForKey: NSFileCreationDate]);
NSLog (#"File type %#", [attribs objectForKey: NSFileType]);
NSLog (#"POSIX Permissions %#", [attribs objectForKey: NSFilePosixPermissions]);
}
//UIWebView delegate calls this method every time user touches any embedded URL's in the current WebPage. I want to grab all the URL's accessed and write them to file.
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {
NSFileManager *fileManager =[NSFileManager defaultmanager];
NSString *path = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents/file1.txt"];
fileHandle = [NSFileHandle fileHandleForWritingAtPath:path];
[fileHandle seekToEndOfFile]; // Moved up next to fileHandleForWritingAtPath since the above would place pointer to start of file again so setting handle to seek to End of File
/* section of code to check if the file at that path is writable or not */
if ([fileManager isWritableFileAtPath:path] == YES)
NSLog (#"File is writable");
else
NSLog (#"File is read only");
/* section of code to check if the file at that path is writable or not ENDS*/
NSURL *url = request.URL;
NSString *currenturl = url.absoluteString;
NSString *currentURL = [NSString stringWithFormat:#"%#\n",currenturl];
NSString *str =[NSString stringWithFormat:#"%#",currentURL];/* has already been set up */
[fileHandle writeData:[str dataUsingEncoding:NSUTF8StringEncoding]];
// testing if string has been written to file by reading it...
NSData *dataBuffer = [fileMgr contentsAtPath:path];
NSString *some;
some = [[NSString alloc] initWithData:dataBuffer encoding:NSASCIIStringEncoding];
NSLog(#"SOme String is: %#",some);
[fileHandle closeFile];
}

I think your issue may be that you're testing Documents/file1.txt and not /Documents/file1.txt
The leading '/' is important
[edit]
May I make a suggestion? Distill this down to what works first and then figure out what makes it fail?
I would recommend using the following form and continuing from there:
if ([fileManager isWritableFileAtPath: #"/Documents/file1.txt"] == YES)
NSLog (#"File is writable");
else
NSLog (#"File is read only");
