  • UIButton doesn't appear on UIToolbar

    - by Sheehan Alam
    I have a UIToolbar where I have dragged a UIButton. When I set the button properties to Custom, and assign an image (or background image) the graphics don't appear. However, when I give it a custom text, the text will appear. Why is it that the images don't appear?

  • Using undecorated UiNavigationBar

    - by Nicsoft
    Hello, I would like to use UINavigationBar without decoration. I.e. I would like to create my own custom buttons and link those to the same actions (e.g. back) as the navigation items were linked to and have no bar presented at the top. I was told that one should use navigation bar even though graphically you should design the interaction yourself. How do I go about doing this? I am quite new to navigation bar to start with... If there is some tutorial you can direct me to it would be great (that is for using nav-bar without decoration). Thanks in advance! Regards, Niklas

  • Passing html parameters to server odd problem

    - by StealthRT
    Hey all i am having a weird problem with sending data back to my server. This is the code i am using: NSString *theURL =[NSString stringWithFormat:@"http://www.xxx.com/confirm.asp?theID=%@&theName=%@&empID=%@&theComp=%@", theConfirmNum, tmpNBUserRow.userName, labelTxt.text, theID]; NSLog(@"%@,%@,%@,%@", theConfirmNum, tmpNBUserRow.userName, labelTxt.text, theID); NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:theURL]]; [request setHTTPMethod:@"POST"]; NSError *error; NSURLResponse *response; NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSString *data=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding]; if ([data isEqualToString:@"Done"]) I can run the code from the browser and it works just fine using the data i got from the NSLog output. The NSLog output for each value is correct. But for some reason when i put a break on the IF ([data isEqualToString:@"Done"]) it has no return value. I checked each value for what it was sending (and again, it was correct in the NSLog output) and i found that the value "theID" said "Out of scope". Although, again, the NSLog had the value in it correctly? So i searched the forum and found a simular problem. I took their advice and added "RETAIN" to the "theID" value like so: theID = [customObjInstance TID]; [theID retain]; However, that did not solve the issue... Here is the console NSLog output: [Session started at 2010-04-11 01:31:50 -0400.] wait_fences: failed to receive reply: 10004003 wait_fences: failed to receive reply: 10004003 nbTxt(5952,0xa0937500) malloc: *** error for object 0x3c0ebc0: double free *** set a breakpoint in malloc_error_break to debug 2010-04-11 01:32:12.270 nbTxt[5952:207] 5122,Rob S.,5122,NB010203 The NSLog values i am sending is the last line "5122,Rob S.,5122,NB010203" Any help would be great :o) David

  • UIAlertView Dismiss Not Really Dismissed

    - by Jim Bonner
    Below is the code I'm using to do a retry on an FBConnect session. When the [self loginToFaceBook] fires FBConnect adds a subview to 'window' which is still the UIAlert view, so when the UIAlert really dismisses it takes the FBConnect view with it. Any idea as to the best way to wait for the UIAlert view to be gone. -(void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex { if([self respondsToSelector:@selector(alertContinue)]) { [self alertContinue]; } } -(void)alertContinue { SocialLiteAppDelegate *appDelegate = (SocialLiteAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate.fbSession logout]; [self loginToFaceBook]; }

  • NSUserDefaults limit integer?

    - by rdesign
    Hey guys, Is it possible to limit an integer in the NSUserDefaults? Off course you can limit it within your app but I am thinking of the TextFields in Settings. Would be great to get some hints. Thanks a lot.

  • XCode newb -- #include can't find my file

    - by morgancodes
    I'm trying to get a third party audio library (STK) working inside XCode. Along with the standard .h files, many of the implimentation files include a file called SKINI.msg. SKINI.msg is in the same directory as all of the header files. The header files are getting included fine, but the compiler complains that it can't find SKINI.msg. What do I need to do to get XCode to happily include SKINI.msg?

  • How to add a badge to the system generated "More" UITabBarItem

    - by Mark Hoffman
    My app has 6 menu items, so the OS shows the first 4, then shows a "More" item that links to a screen where the user can select the other two. My problem is that I want to show a badge on the More item so that the user knows that one of the menu items that is hidden needs their attention. (It's clear to our users which hidden item the badge represents since one of the hidden items is Settings and the other is current Uploads) I don't know how to access the "More" item since the "items" array on UITabBar only contains the 6 actual UITabBarItems that I've created; it doesn't include the system generated "More" item. I've tried setting the badge on one of the hidden UITabBarItems, but no badge is ever displayed. I didn't find much on Google, which makes me wonder if I'm going about this completely wrong. The iTunes app does the same thing when you download items. They display a More item and attach a badge to it, so I figured I was in good company, but I'll be damned if I see how they did that. (Unless they manually created a UITabBarSystemItemMore item and manually handled displaying the other menu items. Ugh.)

  • Can I apply a texture to UIToolbar?

    - by Ben
    I tried doing this: [toolbar setTint:[UIColor colorWithPatternImage:[UIImage imageNamed:@"thingFromMyBundle.png"]]]; but it just ended up black. At first I assumed you weren't allowed to "tint" with a texture, but I've seen apps recently that can do this. Am I missing something? Thanks.

  • setAnimationRepeatAutoreverses not behaved as I expected

    - by danielkwan
    I am starting to learn to use UIView animation. So I wrote the following lines: [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:2.0]; [UIView setAnimationRepeatCount:2]; [UIView setAnimationRepeatAutoreverses:YES]; CGPoint position = greenView.center; position.y = position.y + 100.0f; position.x = position.x + 100.0f; greenView.center = position; [UIView commitAnimations]; In this case, the UIView (a green box) moved back and fore 2 times. So far so good, BUT I found out that after the moving twice, the green box ended up jumped to the "new position" (position.x + 100.0f, position.y + 100.0f) instead of going back to the original position (position.x, position.y). That makes the animation look pretty odd (like after the box swing back to the original position caused by setAnimationRepeatAutoreverses, it jumps back to the new position in the last microsecond!) What is the best way to make the green box NOT jump to the new position at the very last minute?

  • using AudioQueues with AudioFileReadBytes

    - by Santosh
    Hey Im trying to work with Audio queues to play a very big mp3 file (arround 23 hours long). when audio queue asks for buffers though callback, im using AudioFileReadBytes() API to read the bytes from audio file and feed the queue. startQueue fails with the error : prime failed any inputs????? Also I succeeded playing file using AudioFileReadPackets API instead of AudioFileReadBytes(). But the problem with API is that when I seek (fast forward) by a long interval, say 9 hours (for example fast forward from 32 mins playtime to 9:32 mins) then AudioFileReadPackets() takes a long time (almost 2 mins) to read from new location. any comments would be greatly appreciated.

  • NSFetchedResultsController not updating UITableView's section indexes

    - by Luther Baker
    I am populating a UITableViewController with an NSFetchedResultsController with results creating sections that populate section headers and a section index. I am using the following method to populate the section index: - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView { return [fetchedResultsController_ sectionIndexTitles]; } and now I've run into a problem. When I add a new element to the NSManagedObjectContext associated with the NSFetchedResultsController, the new element is saved and appropriately displayed as a cell in the UITableView ... except for one thing. If the new element creates a new SECTION, the new section index does not show up in the right hand margin unless I pop the UINavigationController's stack and reload the UITableViewController. I have conformed to the NSFetchedResultsControllerDelegate's interface and manually invoke [self.tableView reloadSectionIndexTitles]; at the end of both these delegate methods: controller:didChangeSection... controller:didChangeObject... and while I can debug and trace the execution into the methods and see the reload call invoked, the UITableView's section index never reflects the section changes. Again, the data shows up - new sections are physically visible (or removed) in the UITableView but the section indexes are not updated. Am I missing something?

  • - (void)keyboardWasShown not called when switching to another UITextField

    - by Shawn
    I'm having a strange problem that I don't understand. I have a UIScrollView with several UITextField objects. When I switch to the view, I set the first UITextField as firstresponder, and the keyboardWasShown method gets called due to the UIKeyboardDidShowNotification that the view is registered for. The weird thing is, when I touch the next UITextField, the keyboardWasShown method is not called. I don't understand this, since Apple's documentation says "If your interface has multiple text fields, the user can tap between them to edit the values in each one. When that happens, however, the keyboard does not disappear but the system does still generate UIKeyboardDidShowNotification notifications each time editing begins in a new text field." My code I've copied directly from Apple's documentation as well, and it works properly, but it only gets called the first time. What am I missing? - (void)registerForKeyboardNotifications { [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasShown:) name:UIKeyboardDidShowNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWasHidden:) name:UIKeyboardDidHideNotification object:nil]; } - (void)keyboardWasShown:(NSNotification *)aNotification { //if (keyboardShown) return; NSDictionary* info = [aNotification userInfo]; CGSize kbSize = [[info objectForKey:UIKeyboardBoundsUserInfoKey] CGRectValue].size; CGRect bkgndRect = activeField.superview.frame; bkgndRect.size.height += kbSize.height; [activeField.superview setFrame:bkgndRect]; [scrollView setContentOffset:CGPointMake(0.0, activeField.frame.origin.y) animated:YES]; keyboardShown = YES; UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(done)]; self.navigationItem.rightBarButtonItem = doneButton; [doneButton release]; }

  • How to HIDE the iPad keyboard from a MODAL view controller?

    - by Cal
    I'm trying to hide the iPad keyboard from a modal view controller but it doesn't work. I have tried resignFirstResponder but that doesn't have any affect if we are in a modal view controller. I tried resignFirstResponder in a non-modal UINavigationController with the very same UIViewController and the keyboard hides correctly. Does anyone know how solve this problem? Thanks. [Update] it looks like there's something wrong with my code because the resignFirstResponder does work (I made a simple test case instead of using my code). But I still don't know what the problem is.

  • release does not free up memory in low-memory condidtion

    - by user322945
    I am trying to follow the Apple's recommendation to handle low-memory warnings (found in Session 416 of WWDC 2009 videos) by freeing up resources used by freeing up my dataController object (referenced in my app delegate) that contains a large number of strings for read from a plist: - (void)applicationDidReceiveMemoryWarning:(UIApplication *)application { [_dataController release]; _dataController = nil; NSLog([NSString stringWithFormat:@"applicationDidReceiveMemoryWarning bottom... retain count:%i", [_dataController retainCount]]); } But when I run ObjectAlloc within Instruments and simulate a Low-Memory Condition, I don't see a decrease in the memory used by my app even though I see the NSLog statements written out and the retain count is zero for the object. I do pass references to the app delegate around to some of the view controllers. But the code above releases the reference to the _dataController object (containing the plist data) so I would expect the memory to be freed. Any help would be appreciated.

  • KeyboardWillShow with UITextView

    - by Philip J
    Here's the setup: I have a textView (txtReply) where the user puts information I have a UIView that contains a scroll view and some labels, as well as the textView (ChatView) When the user selects the textView, then it brings the keyboard up. I use 'keyboardWillAppear' to move the 'ChatView' up so that the text view is still visible. I then have a reply button that submits the message, draws it into the ChatView, and calls [textView resignFirstResponder]. However, when I do this, it calls the keyboardWillHide, my view resizes, then the it brings the keyboard back up again. Is there something special you have to do to get the keyboard to stay hidden? Thanks

  • NSPredicate that is the equivalent of SQL's LIKE

    - by randombits
    I'm looking for a way to use NSPredicate to set a LIKE condition to fetch objects. In addition to that, an OR would be useful as well. I'm trying to do something where if a user searches "James" I can write an NSPredicate that will do the equivalent of: select * from users where firstname LIKE '%James%' OR lastname LIKE '%James%';

  • How does UIImage work in low-memory situations?

    - by kubi
    According to the UIImage documentation: In low-memory situations, image data may be purged from a UIImage object to free up memory on the system. Does anyone know how this works? It appears that this process is completely transparent and will occur in the background with no input from me, but I can't find any definitive documentation one way or the other. Second, will this data-purge occur when the image is not loaded by me? (I'm getting the image from UIImagePicker). Here's the situation: I'm taking a picture with the UIImagePickerController and and immediately taking that image and sending it to a new UIViewController for display. Sending the raw image to the new controller crashes my app with memory warnings about 30% of the time. Resizing the image takes a few moments, time that I'd rather not spend if there's a 3rd option available to me.

  • How do I programmatically duplicate UIViews built in interface builder?

    - by Cam Spiers
    I want to build up a sub-UIView in Interface Builder (contained within a UIScrollView) with some UILabels contained, I then want to programmatically "copy" this view adjust its left position (by multiples of its width) to achieve a "floating" left effect inside a UIScrollView. I then want to add this copied UIView back into the UIScrollView with different text for the UILabels. The problem is I don't know how and if you can "copy" UIViews.

  • How to capitalize maximally on location-independence … my personal #1-incentive for working as a developer

    - by SomeGuy
    To me the ultimate beauty in working as a developer is the fact that given a nice CV, your are going to find a new job, everywhere at any time. So I would like to ask if somebody here as experience in working while travelling for example. Or job-hopping from metropolis to metropolis every, say, six months. For example I have been investigating for how to get to Brazil. But it seems like that working as an employee in Brazil would be no option, b/c it takes a lot of time/money/effort to get the proper visas and permissions. So the only practical solution would be to freelance and the just travel, while getting your job done wherever you are. I bet my ass that there are loads of IT-guys out there and on here who know exactly what I am talking about. I'm looking forward to interesting ideas and stories.
