How can I do it ? My array looks like this : ( { Name = "John"; Image = "/9j/4AAQSkZJRgABAQAAAQABAAD//gA7Q1JFQVRPUjogZ2QtanBlZyB2MS4wICh1c2luZyBJS kcgSlBFRyB2NjIpLCBxdWFsaXR5ID0gODAK/9sAQwAGBAUGBQQGBgUGBwcGCAoQCgoJCQoUDg8MEBcUGBgXF BYWGh0lHxobIxwWFiAsICMmJykqKRkfLTAtKDAlKCko/9sAQwEHBwcKCAoTCgoTKBoWGigoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgoKCgo/8AAEQgEKwZAAwEiAAIRAQMRAf/........ //big byte array } ) First of all I need to clear whether it is a byte array ?How can I extract image from this ?

  • UITableView headings shown on top of MBProgressHUD

    - by Chris Ballinger
    So I have a subclass of UITableViewController that loads some data from the internet and uses MBProgressHUD during the loading process. I use the standard MBProgressHUD initialization. HUD = [[MBProgressHUD alloc] initWithView:self.view]; [self.view addSubview:HUD]; HUD.delegate = self; HUD.labelText = @"Loading"; [HUD show:YES]; This is the result: . Is there any way to resolve this issue, or should I just abandon MBProgressHUD? Thanks!

  • Extend PickerViews Component while touching

    - by vikingosegundo
    I have a UIPickerView with a variable number of components to display. In its contoller i have this -pickerView:withForComponent: - (CGFloat)pickerView:(UIPickerView *)pv widthForComponent:(NSInteger)component { CGFloat f; if (component == 0) { f = 30; } else { if ([componentsData count]>2) { f = 260.0/([componentsData count]-1); } else{ f = 260.0; } } return f; } this works fine if I call [pickerView reloadAllComponents], but how could I extend a components width if it is touched (and of course shrink all others)?

  • Determine if a subview is visible in a UIScrollView

    - by Jools
    Hi all, I've added a view to my app, that contains a UIScrollView, with a number of UITextViews in it's content view. This works perfectly on OS 3.0 and up, but when I test it on my 2.2.1 iPod touch, there is a UITextView bug that stops any text views automatically updating their content when they are scrolled into view - so you have to send them the setNeedsDisplay message. However, I only want to do this when they start to become visible during the scroll - how do I determine, in the UIScrollView's scrollViewDidScroll delegate method, whether a UITextView is visible in the UIScrollView's frame? Ta. Jools.

  • How to set background color of tableView

    - by Praveen
    Hi Folks, I have tried all the way but could not succeed to set backgroundColor of TableView. setting tableView.backgroundColor and/or cell.backgroundColor to clearColor didn't work when the parent view controller was UIViewContoller. My nib file structure is FileOwner View UITableView (Note: i set the TableView to groupedTable section) First attempt, I created the UIView in the code viewDidLoad UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 160, 300)] autorelease; [view setBackgroundColor:UIColor blueColor]; // color it just to see if it is created at the right place [self.tableView sendSubViewToBack:view]; It works but it hides the content of cell. I am able to see the content of header but not cell content. (But when i change the co-ordinate of view(0,150,160,300) then i am able to see the cell's content but then it loose the backgroundColor of tableview. Second attempt, I created the imageView View ImageView UITableView and set the self.tableView.backgroundColor = [UIColor clearColor]; but did not work. I googled but did not the peaceful answer.

  • resignFirstResponder when tapping UITableView?

    - by Canada Dev
    I have a UITableView with two custom cells and each of them has a subview with a UITextField inside it. I have tried adding a UIButton on top of the UITableView and have it resignFirstResponder but that just means you won't be able to tap anywhere else - not even on the UITextFields to enter text. How do I make it so if I tap outside those two UITextFields, I can call resignFirstResponder, so the user can get back to the other cells? Thanks

  • What causes a UIViewController to become active?

    - by Rob Bonner
    I am sure this is an easy question, but one that has escaped me for some time now. Say I have a UIViewController, either defined as a root in an XIB or on a stack. At some point in my code I want to replace it with another view controller. Just flat out replace it. How would I do that? I have tried defining the controller and assigning, but not sure what actually makes it push on the screen with the absence of a navigation controller.

  • Remove newline character while XML parsing

    - by Prashant
    Hi, I am facing a problem while XML parsing. I have an NSMutablestring currentElementValue that has newlines into it. It has been received as an XMl from a web source. Even when i am trying to remove newline charactersets of substring the first 3 char there is no effect on the string. What can be done here? Regards PC Code is (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { if(!currentElementValue) currentElementValue = [[NSMutableString alloc] initWithString:string]; else { [currentElementValue substringFromIndex:3]; [currentElementValue stringByTrimmingCharactersInSet:[NSCharacterSet newlineCharacterSet]]; NSLog(@"Processing Value : %@ with length %d", currentElementValue,[currentElementValue length] ); }

  • Reload a UITable on the fly when editing a UITextField inside one of the cells

    - by Saze
    I have a UITable containing some customs UITableCells. Those cells contain a few UILabels and a UITextField. The datasource of the table comes from a main controller's property. (This controller is also the delegate and the dataSource for the table). Here's a simplified screenshot of the UI: Now, I need to update "on the fly" the content of all the UILabels when the user edits one of the UITextFields. To do so, at the I am listening to the "Editing Changed" event at the UITextField level. This triggers the following action: - (IBAction) editChangeHandler: (id) sender { MyAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; [[delegate.viewController.myDataSourceArray objectAtIndex:self.rowIndex] setANumber: [theTextField.text intValue]]; [delegate.viewController reloadRows]; } The reloadRows method in the viewController is as such: - (void) reloadRows { NSLog(@"called reloadRows"); //perform some calculations on the data source objects here... [theUITable reloadData]; } My problem here is that whenever the user changes the value in the field, the reloadRows method is successfully called, so is apparently the reloadData but it also causes the keyboard to be dismissed. So in the end, the user can only touch one key when editing the TextField before the keyboard is dismissed and the table reloaded. Does anybody knows a solution to this or have experienced the same issue?

  • So where is this calling super?

    - by dontWatchMyProfile
    From the Core Data docs: Inheritance If you have two subclasses of NSManagedObject where the parent class implements a dynamic property and its subclass (the grandchild of NSManagedObject) overrides the methods for the property, those overrides cannot call super. @interface Parent : NSManagedObject @property(nonatomic, retain) NSString* parentString; @end @implementation Parent @dynamic parentString; @end @interface Child : Parent @end @implementation Child - (NSString *)parentString { // this throws a "selector not found" exception return parentString.foo; } @end very, very funny, because: I see nobody calling super. Or are they? Wait... parentString.foo results in ... a crash ??? it's a string. How can that thing have a .foo suffixed to it? Just another documentation bug?

  • Does Core Data automatically validate new values when they are set?

    - by mystify
    In this question, someone asked how to write a validation method for Core Data. I did that, and it looks cool. But one thing doesn't happen: The validation. I can easily set any "bad" value and this method doesn't get called automatically. What's the concept behind this? Must I always first call the validation method before setting any value? So would I write setter methods which call the appropriate validation method first? And if yes, what's the point of following a strict convention in how to write the validation method signature? I guess there's also some automatic way of validation, then. How to activate this?

  • Compare filedate before download it

    - by Christian
    Hi, I have an app which is downloading several plist-files when starting the app and storing them in the NSHomeDirectory/Documents/ path. This will take some time and often there is only one file that changed. My questions are: -how can I get the date of the files (the stored one and the file on my webserver)? -how can I compare the date of the stored file with the date of the file on my webserver?
