POAppend Data To NSDictionary

Body
copied!<p>My app is of type SplitView and I am using <code>UITableView</code> to display the name of sites. In <code>didSelectRowAtIndexPath</code> method, I am using the following the lines of code ::</p> <pre><code>dateString = [formatter stringFromDate:[NSDate date]]; dict = [[NSDictionary alloc] init]; dict = [NSDictionary dictionaryWithObjectsAndKeys: urlString, dateString, nil]; [history addObject:dict]; NSLog(@"dateString: %@", dateString); //will let you know if it's nil or not NSLog(@"urlString : %@", [dict objectForKey:dateString]); NSString *docDir = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]; NSLog(@"docDir is yoyo :: %@", docDir); NSString *spaceFilePath = [docDir stringByAppendingPathComponent:@"space.txt"]; [history writeToFile:spaceFilePath atomically: TRUE]; </code></pre> <p>I am trying to add the url of sites visited alongwith the timestamp into the <code>NSDictionary</code> "dict". I have initialised formatter in <code>viewDidLoad</code> method. History is an array which stores the list of dictionaries.</p> <p>I have used the following lines of code in <code>viewDidLoad</code> method :</p> <pre><code>formatter = [[NSDateFormatter alloc] init]; [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"]; </code></pre> <p>I want to append the name of the new site visited into the already existing file space.txt.</p> <p>But, however, only one name appears (the last visited site's url). How can I append the newly visited siteNames into my already existing file space.txt? I am unable to sort out this issue. </p> <p>Thanks and Regards.</p>
