  • persistent view controller

    - by derrichh
    Im building an iphone radio application and I want to have the controls, play, pause, stop, etc. in a tool bar (a custom view controller) at the bottom of the application. I want to keep this there throughout all the views so you can control the audio while navigating through the other parts of the application (multiple view/table controllers). Is there a way to create a view that stays in place like a tab bar?

  • 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

  • runModalForWindow throttles http requests

    - by Nikita Rybak
    I have url connection, which normally works fine NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:delegate]; But when I create a modal window, no request ever receives response: [NSApp runModalForWindow:window]; If I comment this line out, thus creating a 'standard' window, everything works. I tried implementing all methods from NSURLConnectionDelegate, not a single of them called. I suspect this is something about 'run loops', but have little experience in this area. Does anybody have experience in this? Thank you

  • autorelease object not confirming protocol does not give any warning

    - by Sahil Wasan
    I have a class "ABC" and its method which returns non autoreleases object of that class. @interface ABC:NSObject +(ABC *)aClassMethodReturnsObjectWhichNotAutoreleased; @end @implementation ABC +(ABC *)aClassMethodReturnsObjectWhichNotAutoreleased{ ABC *a = [[ABC alloc]init]; return a; } @end If I have a protocol Foo. @Protocol Foo @required -(void)abc; @end My ABC class is "not" confirming Foo protocols. 1st call id<Foo> obj = [ABC aClassMethodReturnsObjectWhichNotAutoreleased]; //show warning It shows warning "Non Compatible pointers.." thats good.Abc did not confirm protocol Foo BUT 2nd call id<Foo> obj = [NSArray arrayWithObjects:@"abc",@"def",nil]; // It will "not" show warning as it will return autorelease object.NSArray don't confirm protocol Foo In first call compiler gives warning and in second call compiler is not giving any warning.I think that is because i am not returning autorelease object. Why is compiler not giving warning in 2nd call as NSArray is also not confirming FOO Thanks in advance

  • Read Call History from iPhone on iOS 5 and above

    - by Sandeep Dhama
    I am developing an application and need to read the users call history from iPhone.I have go though all the forums and google it and found that we can get the records from teh callHistory sqlite database by "private/var/root/Library/CallHistory/call_history.db". But this path is not working from iOS 5 and above. Seems like apple has changed all their database path and structure so that no one can accees it. I have also seen some of the application on iTunes who are capable of getting the users call history like:-https://itunes.apple.com/us/app/callog/id327883585?mt=8 I have also check a mac desktop utility called "WonderShare Dr.Fone" which will fetch all the data from your iPhone like call history messages, notes , etc.How this utility is fetching the call history records and other details? If their is any API or private APIs by which i can get the callHistory data path please let me know.

  • Unable to call storyboard from xib

    - by Shruti Kapoor
    I am new to iOS development. I am trying to connect to a storyboard from xib file. My xib View Controller has a "Login" which if successful should connect to storyboard. I have googled and searched on stackoverflow for a solution and I am using this code that is given everywhere: UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil]; YourViewController * yourView = (YourViewController *)[storyboard instantiateViewControllerWithIdentifier:@"identifier ID"]; I have created an identifier for my storyboard as well. However, I am not being redirected to the storyboard no matter what I try. When the login finishes, I go back to my main View Controller (xib). I should be instead redirected to the storyboard. Here is what my code looks like in a file called ProfileTabView.m: -(void) loginViewDidFinish:(NSNotification*)notification { [[NSNotificationCenter defaultCenter] removeObserver:self]; UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil]; ProfileTabView * yourView = (ProfileTabView *)[storyboard instantiateViewControllerWithIdentifier:@"myID"]; } I have implemeted this code in the function that gets called once the login is successful. However, the storyboard "Storyboard" never gets called. Am i doing this right? Am I supposed to be writing this code anywhere else? Thanks a lot for any help :)

  • SQLite3 or SQLite Manager make me crazy !!! Please help me !! I have a presentation next week

    - by ahmet732
    My friend added 90 rows into the database, I tied it up to my app. In my table view name of my variables are shown in proper fashion but when I tapped one of them, in detailsViewController their description is wrong. It shows very old description of variables not the new ones in database. Moreover, it displays the same description for different variables. What's the problem ? What am i missing? My database is correct. It displays same desscriptions for different values. It makes me worried about. Additionally, when I added a new row to my db, it accepts it but it does not perceive it when i run the app. It shows new row in my tableview if and only if I change the name of my db file. I do not want to use another SQL manager ..

  • editButtonItem set but no minus buttons?

    - by QAD
    My edit button is placed in viewDidLoad: self.navigationItem.rightBarButtonItem = self.editButtonItem; It shows up correctly on the nav bar, and tapping this button indeed change it to Done. However, no minus buttons show up in my table rows. Swiping a row, then tap Delete works, though. Any ideas? EDIT 1: Here's how I'm doing: - (void)loadView { tableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; tableView.delegate = self; tableView.dataSource = self; tableView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; self.view = tableView; } EDIT 2: My observation is that the edit and minus buttons display fine if my tableview is created in IB (RootViewController). The other two (or three) tableview are created by the aforemention code, so that might be the problem. Guess I'd have to dive in to isEditing, editing and whatnot.

  • Using drawAtPoint with my CIImage not doing anything on screen

    - by Adam
    Stuck again. :( I have the following code crammed into a procedure invoked when I click on a button on my application main window. I'm just trying to tweak a CIIMage and then display the results. At this point I'm not even worried about exactly where / how to display it. I'm just trying to slam it up on the window to make sure my Transform worked. This code seems to work down through the drawAtPoint message. But I never see anything on the screen. What's wrong? Thanks. Also, as far as displaying it in a particular location on the window ... is the best technique to put a frame of some sort on the window, then get the coordinates of that frame and "draw into" that rectangle? Or use a specific control from IB? Or what? Thanks again. // earlier I initialize a NSImage from JPG file on disk. // then create NSBitmapImageRep from the NSImage. This all works fine. // then ... CIImage * inputCIimage = [[CIImage alloc] initWithBitmapImageRep:inputBitmap]; if (inputCIimage == Nil) NSLog(@"could not create CI Image"); else { NSLog (@"CI Image created. working on transform"); CIFilter *transform = [CIFilter filterWithName:@"CIAffineTransform"]; [transform setDefaults]; [transform setValue:inputCIimage forKey:@"inputImage"]; NSAffineTransform *affineTransform = [NSAffineTransform transform]; [affineTransform rotateByDegrees:3]; [transform setValue:affineTransform forKey:@"inputTransform"]; CIImage * myResult = [transform valueForKey:@"outputImage"]; if (myResult == Nil) NSLog(@"Transformation failed"); else { NSLog(@"Created transformation successfully ... now render it"); [myResult drawAtPoint: NSMakePoint ( 0,0 ) fromRect: NSMakeRect ( 0,0,128,128 ) operation: NSCompositeSourceOver fraction: 1.0]; //100% opaque [inputCIimage release]; } }

  • My UITableView has duplicated rows

    - by Mark
    Im not sure why, but my UITableView, which isnt anything fancy, is showing repeating rows when it shouldnt be. It seems that the rows that get added when the user scrolls (i.e. the rows that are off the screen to start with) are getting the data for the wrong row index. Its almost like when a new cell is de-queued, it's using a cell that 'was' used, but wasn't cleaned up correctly. Do you need to 'clean up' cells that are de-queue so that new cells dont use cells that are already created? my code is as below: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CustomCellIdentifier = @"CustomCellIdentifier"; MyDayCell *cell = (MyDayCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MyDayCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[MyDayCell class]]) cell = (MyDayCell *)oneObject; } NSUInteger section = [indexPath section]; NSUInteger row = [indexPath row]; NSArray *thisSectionItems = (NSArray*)[self.listData objectForKey: [[NSNumber alloc] initWithInt:section]]; MyDayDetails *rowData = [thisSectionItems objectAtIndex:row]; //setup my cells data here... return cell; } Is there anything wrong with this code? has anyone seen anything like this before?

  • UITableView not getting populated with sqlite database column

    Here's the code of a method I used to populate UITableView with the contents of a column in sqlite database. However, this is giving no errors at run-time but still does not give any data in UITableView. If anyone could help, it'll be highly appreciated. - (void)viewDidLoad{ [super viewDidLoad]; self.title = @"Strings List"; UITableViewCell *cell; NSString *docsDir; NSArray *dirPaths; sqlite3_stmt *statement; // Get the documents directory dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); docsDir = [dirPaths objectAtIndex:0]; // Build the path to the database file databasePath = [[NSString alloc]initWithString: [docsDir stringByAppendingPathComponent:@"strings.sqlite"]]; NSFileManager *filemgr = [NSFileManager defaultManager]; if ([filemgr fileExistsAtPath: databasePath ] == NO) { const char *dbpath = [databasePath UTF8String]; if (sqlite3_open(dbpath, &contactDB) == SQLITE_OK) { NSString * query = @"SELECT string FROM strings"; const char * stmt = [query UTF8String]; if (sqlite3_prepare_v2(contactDB, stmt, -1,&statement, NULL)==SQLITE_OK){ if (sqlite3_step(statement) == SQLITE_ROW) { NSString *string = [[NSString alloc]initWithUTF8String:(const char*)sqlite3_column_text(statement, 0)]; cell.textLabel.text = string; } } else NSLog(@"Failed"); sqlite3_finalize(statement); } sqlite3_close(contactDB); } }

  • UISearchBar in UINavigationBar with ScopeBar

    - by ncipollina
    I am trying to put a UISearchBar inside of the UINavigationBar, which I am able to do without much problem. The problem is that I have logic when editing to show the Scope Bar. This all works fine, with one exception. The navigation bar tries to center the UISearchBar inside of the title view. This causes the search bar to move up above the navigation bar. I tried adding some logic to set the frame of the search bar so that it just draws overtop of my main view, which is fine. I can only set the height, which causes the search bar to draw over the view just fine, but it isn't wide enough to cover the whole screen. If I set the width on the frame, it goes back to the same behavior of trying to center the UISearchBar on the navigation bar. Anyone know how I can accomplish this? Thanks, Nick

  • How do I enable spell checking within an NSTextField?

    - by Luke
    I have an NSTextField that I would like to enable "as-you-type" spell checking. When I load my application I can do this from the Menu Bar Edit Spelling and Grammar Check Spelling While Typing. I would like this option to be enabled by default. Within IB I can enable this for a NSTextView but I would like to use NSTextField for this part of the UI. Thank you.

  • Compile error on action for iPhone app: "error:expected ')' before ';' token"

    - by Jamis Charles
    I'm working through the tutorials in the "Beginning iPhone Development" book. I'm on chapter 4 and I'm getting the following compile error on the "if (segment == kShowSegmentIndex)" line: error:expected ')' before ';' token Here's my code: - (IBAction)toggleShowHide:(id)sender{ UISegmentedControl *segmentedControl = (UISegmentedControl *)sender; NSInteger segment = segmentedControl.selectedSegmentIndex; if (segment == kShowSegmentIndex) [switchView setHidden:NO]; else [switchView setHidden:YES]; } I've compared it with the code in the book several times and have retyped it. Sounds like this error is caused by improper brace placement. Any thoughts?

  • Best practice to pass a value from pop up control on iPad.

    - by Tattat
    It is an iPad app based on SDK 3.2. I have a MainUIView, that is subclass from UIView, it have a UIButton and a UILabel. When user press the UIButton, the pop up control will be appeared with a table view. When the user select a cell from the table view, the UILabel changes content base on the user click, and the pop up table view will disappear. The question is, how can I pass the "selected cell" to the UILabel. I am thinking making a "middle man" object. When the user click the UIButton, and the "middle man" will pass to the table. When the cell is selected, the "middle man" will store the idx, and call the UILabel change content from the value of "middle man". But I think it is pretty complex to implement, is there any easier way to implement it? thz u.
