    <p>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...<a href="http://pastebin.com/Tx7CsXVB" rel="nofollow">http://pastebin.com/Tx7CsXVB</a></p> <pre><code>- (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.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
