  • UITableViewCell separator line disappears on scroll

    - by iconso
    I'm trying to have a separator cell with a custom image. I did try something like that: In my cellForRowAtIndexPath: NSString *cellIdentifier = [NSString stringWithFormat:@"identifier"]; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier]; } cell.textLabel.font = [UIFont fontWithName:@"Helvetica" size:19]; cell.textLabel.text = [self.menuItems objectAtIndex:indexPath.row]; cell.textLabel.textColor = [UIColor colorWithRed:128/255.0f green:129/255.0f blue:132/255.0f alpha:1.0f]; cell.backgroundColor = [UIColor whiteColor]; UIImageView *imagView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"reaL.png"]]; imagView.frame = CGRectMake(0, cellHeight, cellWidth, 1); [cell.contentView addSubview:imagView]; switch (indexPath.row) { case 0: cell.imageView.image = [self imageWithImage:[UIImage imageNamed:@"img1.png"] scaledToSize:CGSizeMake(27, 27)]; cell.imageView.highlightedImage = [self imageWithImage:[UIImage imageNamed:@"route.png"] scaledToSize:CGSizeMake(27, 27)]; break; case 1: cell.imageView.image = [self imageWithImage:[UIImage imageNamed:@"img.png"] scaledToSize:CGSizeMake(27, 27)]; cell.imageView.highlightedImage = [self imageWithImage:[UIImage imageNamed:@"money.png"] scaledToSize:CGSizeMake(27, 27)]; break; case 2: cell.imageView.image = [self imageWithImage:[UIImage imageNamed:@"auto.png"] scaledToSize:CGSizeMake(27, 27)]; cell.imageView.highlightedImage = [self imageWithImage:[UIImage imageNamed:@"cars.png"] scaledToSize:CGSizeMake(27, 27)]; break; case 3: cell.imageView.image = [self imageWithImage:[UIImage imageNamed:@"impostazioni.png"] scaledToSize:CGSizeMake(27, 27)]; cell.imageView.highlightedImage = [self imageWithImage:[UIImage imageNamed:@"impostazioni.png"] scaledToSize:CGSizeMake(27, 27)]; // cell.imageView.contentMode = UIViewContentModeScaleAspectFill; break; case 4: cell.imageView.image = [self imageWithImage:[UIImage imageNamed:@"info.png"] scaledToSize:CGSizeMake(27, 27)]; cell.imageView.highlightedImage = [self imageWithImage:[UIImage imageNamed:@"info.png"] scaledToSize:CGSizeMake(27, 27)]; break; default: break; } return cell; When I lunch the app everything is good, but when I scroll the the table, or when I select a cell the separator lines disappear. How I can have a permanent custom line separator?

  • Usage of autorelease pools for fetch method

    - by Matthias
    Hi, I'm a little bit confused regarding the autorelease pools when programming for the iPhone. I've read a lot and the oppionions seem to me from "Do-NOT-use" to "No problem to use". My specific problem is, I would like to have a class which encapsulates the SQLite3 Access, so I have for example the following method: -(User*)fetchUserWithId:(NSInteger)userId Now, within this method a SQL query is done and a new user object is created with the data from the database and then returned. Within this DB Access class I don't need this object anymore, so I can do a release, but since the calling method needs it, I would do an autorelease, wouldn't I? So, is it okay to use autorelease here oder would it gain too much memory, if this method is called quite frequently? Some websites say, that the autorelease pool is released first at the end of the application, some say, at every event (e.g. user touches something). If I should not use autorelease, how can I make sure, that the object is released correctly? Can I do a release in the fetch method and hope, that the object is still there until the calling method can do a retain? Thanks for your help! Regards Matthias

  • Using a proxy for NSURLConnection

    - by SideSwipe
    Is there any way to get the content of a webfile (namely a .html Document) using a proxy, which is not defined in the system settings? I know that NSURLConnection is the right way to download a web file into a variable and not into a file (for which we should use NSURLDownload), but I don't find a way to use a proxy for it. Are there some unofficial APIs, Libraries or Classes or such I could use for what I want to do? I'm not that pro in Mac Programming, so I'm searching for something more or less simple. SideSwipe

  • How to call another class's method from my app delegate

    - by Jared
    I have an application that utilizes UILocalNotifications to pop-up UIAlertViews. When the notification fires, the user chooses to go into the app, and this method is called from my app delegate: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {...} Where I can handle it and where I also prompt another alertview for more information. So when the app launches, it is displaying view A, and then the alertview pops up and prompts for input. This alertview, however, is originating from my app delegate. I need to be able to reload view A when the user hits Yes/No on the alertview. How can I do that from within my app delegate? Any help is appreciated!!

  • Creating Actions from UIActionSheets help

    - by user337174
    I am using two UIAction sheets within my current project. I can get one to work perfectly fine but when i insert a second action sheet it runs the same arguements as the first. How do i define the actionsheets seperatly? -(IBAction) phoneButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Phone: %@",phone],nil]; actionSheet.actionSheetStyle = UIActionSheetStyleDefault; [actionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [actionSheet release]; } -(IBAction) mapButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *mapActionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Map"],nil]; mapActionSheet.actionSheetStyle = UIActionSheetStyleDefault; [mapActionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [mapActionSheet release]; } -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if(buttonIndex == 0){ NSString *callPhone = [NSString stringWithFormat:@"tel:%@",phone]; NSLog(@"Calling: %@", callPhone); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]]; } }

  • Core Data fetch request with array

    - by JK
    I am trying to set a fetch request with a predicate to obtain records in the store whose identifiers attribute match an array of identifiers specified in the predicate e.g. NSString *predicateString = [NSString stringWithFormat:@"identifier IN %@", employeeIDsArray]; The employeeIDsArray contains a number of NSNumber objects that match IDs in the store. However, I get an error "Unable to parse the format string". This type of predicate works if it is used for filtering an array, but as mentioned, fails for a core data fetch. How should I set the predicate please?

  • When to release a class with delegates

    - by Stefan Mayr
    A quick question to delegates. Lets say, CLASSA has a delegate defined: @protocol MyDelegate -(void) didFinishUploading; @end In CLASSB I create an instance of CLASS A -(void) doPost { CLASSA *uploader = [[CLASSA alloc] init]; uploader.delegate = self; // this means CLASSB has to implement the delegate uploader.post; } and also in CLASSB: -(void)didFinishUploding { } So when do I have to release the uploader? Because when I release it in doPost, it is not valid anymore in didFinishUploading. Thanks

  • Using NSUserDefaults to load data depending on which table view cell is pressed

    - by Bad_APPZ
    I want my app to work just like the 'contacts' app on iOS. When a user selects a certain TableViewCell, i want to load certain data. No Matter which cell is pressed, Either "Joseph, Richard, or Shannon", This view comes up: Both of the views look the exact same, but they just display different information. So i guess my question is: How can I programmatically set a key @"cell1" @"cell2", etc... for each cell using NSUserDefaults? But here is the catch, I dont know how many cells will be added, so i cant hard code this, How can I create a key for each table view cell for how ever many is added? Thanks for the help!

  • Tab-Bar not hiding on all views

    - by Sheehan Alam
    I have a tab-bar controller that loads a RootView. The RootView has 4 buttons that will load a UITableView I don't want my tab-bar to be visible in the RootView so I added the following code: -(void)viewDidLoad{ self.hidesBottomBarWhenPushed = YES; } When I initially load the app the tab-bar doesn't appear, but when I click on a button, and go back to the RootView the tab-bar still appears. I have tried placing this code in viewWillAppear and other application lifecycle methods but no luck.

  • Oracle access from iOS

    - by Michael Lowman
    I'm developing an iPad app that needs read-only access to an Oracle database. Is there any way to do this? As far as I can see, the only options are using OCI, which requires a prebuilt binary in the form of the instant client (and not built for ARM), or OJDBC drivers. Both of these seem to be out of the question. In my research I have discovered that libmysqlclient compiles for arm with minimal tuning. This is a stretch, but is there any possible way to use this to my advantage? I have seen this product providing odbc connectivity through the use of a Windows gateway machine using the ODBC client libraries, but this solution really isn't an option for me at the present time. Any ideas?

  • Designing the iPhone interface in a nib or in code?

    - by Jacob Relkin
    I've been pondering over this question for a long time already. On the one hand, Interface Builder offers a really easy way to design the interface and wire the elements up with objects in code. On the other hand, in larger projects, Interface Builder becomes a hassle to maintain. Any suggestions would be greatly appreciated.

  • className method?

    - by fuzzygoat
    I have just been watching the Stanford iPhone lecture online from Jan 2010 and I noticed that the guy from Apple keeps referring to getting an objects class name using "className" e.g. NSArray *myArray = [NSArray arrayWithObjects:@"ONE", @"TWO", nil]; NSLog(@"I am an %@ and have %d items", [myArray className], [myArray count]); However, I can't get this to work, the closest I can come up with it to use class, is className wrong, did it get removed, just curious? NSArray *myArray = [NSArray arrayWithObjects:@"ONE", @"TWO", nil]; NSLog(@"I am an %@ and have %d items", [myArray class], [myArray count]); Gary

  • using KVO to update an NSTableView filtered by an NSPredicate

    - by KingRufus
    My UI is not updating when I expect it to. The application displays "projects" using a view similar to iTunes -- a source list on the left lets you filter a list (NSTableView) on the right. My filters update properly when they are examining any simple field (like name, a string), but not for arrays (like tags). I'm removing a tag from one of my objects (from an NSMutableArray field called "tags") and I expect it to disappear from the list because it no longer matches the predicate that is bound to my table's NSArrayController. ProjectBrowser.mm: self.filter = NSPredicate* srcPredicate = [NSPredicate predicateWithFormat:@"%@ IN %K", selectedTag, @"tags"]; Project.mm: [self willChangeValueForKey:@"tags"]; [tags removeAllObjects]; [self didChangeValueForKey:@"tags"]; I've also tried this, but the result is the same: [[self mutableArrayValueForKey:@"tags"] removeAllObjects]; Interface Builder setup: a ProjectBrowser object is the XIB's File Owner an NSArrayController (Project Controller) has its Content Array bound to "File's Owner".projects Project Controller's filter predicate is bound to "File's Owner".filter NSTableView's column is bound to "Project Controller".name
