  • how can I know current viewcontroller name in iphone

    - by Shikhar
    I have BaseView which implement UIViewController. Every view in project must implement this BaseView. In BaseView, I have method: -(void) checkLoginStatus { defaults = [[NSUserDefaults alloc] init]; if(![[defaults objectForKey:@"USERID"] length] > 0 ) { Login *login=[[Login alloc] initWithNibName:@"Login" bundle:nil]; [self.navigationController pushViewController:login animated:TRUE]; [login release]; } [defaults release]; } The problem is my Login view also implement BaseView, checks for login, and again open LoginView i.e. stuck in to recursive calling. Can I check in checkLoginStatus method if request is from LoginView then take no action else check login. Ex: (void) checkLoginStatus { if(SubView is NOT Login){ defaults = [[NSUserDefaults alloc] init]; if(![[defaults objectForKey:@"USERID"] length] 0 ) { Login *login=[[Login alloc] initWithNibName:@"Login" bundle:nil]; [self.navigationController pushViewController:login animated:TRUE]; [login release]; } [defaults release]; } } Please help..

  • iPhone Map: Identifying Users Location

    - by senfo
    I have a number of annotations on my map, in addition to the users current location. This works fine, except the default color for the users current location is the same as all of the other annotations. I'd like to make the pin green for the users current location so that it's uniquely identifiable from the other pins. How do I do this? Bellow is the method I've been using (I can't find a way to determine which annotation is the users current location): - (MKAnnotationView *)mapView:(MKMapView *)mapViewLocal viewForAnnotation:(id <MKAnnotation>)annotation { static NSString *identifier = @"Pin"; MKPinAnnotationView *pinView = (MKPinAnnotationView*)[mapView dequeueReusableAnnotationViewWithIdentifier:identifier]; if (pinView == nil) { pinView = [[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:identifier] autorelease]; pinView.rightCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeDetailDisclosure]; pinView.animatesDrop = YES; pinView.canShowCallout = YES; } else { pinView.annotation = annotation; } return pinView; }

  • "No architectures" error when compiling objective flickr for iphone device

    - by user176723
    I'm getting the following error when I attempt to compile my XCode project to debug on my device. No architectures to compile for (ARCHS=x86_64, VALID_ARCHS=armv6 armv7). I've included ObjectiveFlickr in my project just as the readme describes. I've gone through the process several times and redownloaded objectiveFlickr a few times to start over. I've gotten objectiveFlickr to work on devices in the past. I don't know why I am suddenly having trouble. Can anybody point me to something that might hold the clue I need? Any other info I need to provide? I made only changes to my project that are specified by the OF documentation. I also get this error when compiling the included snap-n-run example project provided with OF. So I must be missing something beneath my project. Thanks, Charlie

  • iphone scanning a dat file for data

    - by Brodie4598
    I am trying to remake a program I have made in C# in OBJ-C.In C# I used streamreader to search the data file for the line I am looking for then convert that line into a string that I can work with. I have looked at NSScanner but I'm not sure if thats quite waht I'm looking for but I'm by no means a cocoa expert. All I would like to be able to do is have it search a data file for an occurance of a string, then when/if it finds an occurance of that string, it returns the line that string was found on as a string. Any ideas?

  • Small gaps in section headers with custom headers - iPhone / Objective-C

    - by zhar
    Hi there! Since I wanted to use the standard section header with a different font size, I just made custom section headers by using an UIImageView with the standard section header as an image. It looks fine at first, but when I scroll the table, there are small gaps below and above the section headers: Since I am not allowed to post images or more than one hyperlink yet, I will have to provide you with one link to those images: Click me! Picture: How it looks like without touching anything Picture: Dragging the table down Picture: Dragging/Scrolling the table up So as you can hopefully see, there is a small empty gap under (2nd pic) and above (3rd pic) the section header. Another thing to mention is, that the standard behaviour of non-custom section headers is, that they don't become transparent when I drag the table down (making the table offset < 0.0). Is there a way to make custom section headers mimic the same behaviour without those annoying gaps? Greetings, Zhar

  • Suppressing the language select button iPhone

    - by AWinter
    I'm working on an application now that contains an account register section. One field with secureTextEntry = NO (for registering only). The idea is this make registration faster and hopefully increases the number of signups. It's simple enough for me to just place a regular UITextField but if the user has any additional language keyboards then it's possible for the user to enter non-password friendly characters. Unlike in when secureTextEntry = YES. I know I can do textField.keyboardType = UIKeyboardTypeASCIICapable to get the text field to display the ASCII keyboard first, but the user will still have the keyboard switch button which will allow them to get to undesirable characters. Is there a simple method for suppressing the international button or forcing ASCII only keyboard with no international button? [EDIT] Another perhaps better option might be to suppress multi byte keyboards or even to display the text in the case that secureTextEntry = YES any ideas here? [EDIT AGAIN] I've decided it's a really bad idea to suppress the international button as non-multibyte characters should all be allowed.

  • Count files in directories AND subdirectories? iPhone

    - by AWright4911
    I am trying to count entire files in a directory, including subdirectories. This is what I have to count files in the first folder: -(NSString *)numberOfPhotos { NSString *MyPath = @"/rootdirectory/"; NSArray *directoryContent = [[NSFileManager defaultManager] directoryContentsAtPath:MyPath]; return [NSString stringWithFormat:@"%d", [directoryContent count]]; } I was thinking maybe something like for (file in folder){ [file count] { but doesnt seem to work.

  • iPhone / NSArray : How do I format a text file to be read in using arrayWithContentsOfFile

    - by nickthedude
    I have several large word lists and I had been loading them in place in the code as follows: NSArray *dict3 = [[NSArray alloc] initWithObjects:@"abled",@"about",@"above",@"absurd",@"absurdity", ... but now it is actually causing an exc_bad_access error weirdly, i know it seems implausible but for some reason IT IS causing it. (trust me on this I just spend the better part of a day debugging this crap) Anyway, I'm looking to get these humongous lines of code out of my files but I'm not sure what the best approach is. I guess I could do a plist but I need to figure out how to automate the process. it be easiest if I could just use the text files I've been compiling so if anyone knows how I can format the text file so that the myArray = [NSArray arrayWithContentsOfFile: @"myTextFile.txt"]; will be read in correctly as one word per element in the array it would really be appreciated. Thanks, Nick

  • iPhone - dismiss multiple ViewControllers

    - by Oscar Peli
    Hi there, I have a long View Controllers hierarchy; in the first View Controller I use this code: SecondViewController *svc = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; [self presentModalViewController:svc animated:YES]; [svc release]; In the second View Controller I use this code: ThirdViewController *tvc = [[ThirdViewController alloc] initWithNibName:@"ThirdViewController" bundle:nil]; [self presentModalViewController:tvc animated:YES]; [tvc release]; and so on. So there is a moment when I have many View Controllers and I need to come back to the first View Controller. If I come back one step at once, I use in every View Controller this code: [self dismissModalViewControllerAnimated:YES]; If I want to go back directly from the, say, sixth View Controller to the first one, what I have to do to dismiss all the Controllers at once? Thanks

  • Playing video and audio in iPhone not working...

    - by Scott
    So we have buttons linked up to display images/videos/audio on click depending on a check we do earlier. That part works fine. It knows which one to play, however, when we click the buttons for video and audio, nothing happens. The image one works fine. The video and audio are being taken for a URL online, they are not local, but everywhere said this was still possible. Here is a little snippet of the code where we play the two files: if ( [fName hasSuffix:@".png"]) { NSLog(@"PICTURE"); NSURL *url = [NSURL URLWithString: fName]; UIImage *image = [UIImage imageWithData: [NSData dataWithContentsOfURL:url]]; self.view = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]]; // self.view.backgroundColor = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"MainBG.jpg"]]; [self.view addSubview:[[UIImageView alloc] initWithImage:image]]; } if ( [fName hasSuffix:@".mp4"]) { NSLog(@"VIDEO"); //NSString *path = [[NSBundle mainBundle] pathForResource:fName ofType:@"mp4"]; //NSLog(path); NSURL *url = [NSURL fileURLWithPath:fName]; MPMoviePlayerController *player = [[MPMoviePlayerController alloc] initWithContentURL:url]; [player play]; } if ( [fName hasSuffix:@".mp3"]) { NSLog(@"AUDIO"); NSURL *url = [NSURL fileURLWithPath:fName]; NSData *soundData = [NSData dataWithContentsOfURL:url]; AVAudioPlayer *avPlayer = [[AVAudioPlayer alloc] initWithData:soundData error: nil]; [avPlayer play]; } See anything wrong? By the way it compiles and runs, but nothing happens when we hit the button that executes that code.

  • Using XCode and instruments to improve iPhone app performance

    - by MrDatabase
    I've been experimenting with Instruments off and on for a while and and I still can't do the following (with any sensible results): determine or estimate the average runtime of a function that's called many times. For example if I'm driving my gameLoop at 60 Hz with a CADisplayLink I'd like to see how long the loop takes to run on average... 10 ms? 30 ms etc. I've come close with the "CPU activity" instrument but the results are inconsistent or don't make sense. The time profiler seems promising but all I can get is "% of runtime"... and I'd like an actual runtime.

  • iPhone iOS4: API for AVRCP (ff/rewind commands on Bluetooth headsets)

    - by Michael Kessler
    Hi, I know that AVRCP abilities were added to iOS 4.1 (in iPod application now you can forward and rewind songs by using hardware buttons on supporting headsets). I am trying to find any API for using these abilities in a music application that I work on. The requirement is to catch play/stop, forward and rewind buttons events from the headset. Any information will be more than welcome. Thank you.

  • iPhone PopUp RGB colors

    - by McLas
    Hi, I am presenting a UIView with an animation that takes half of the screen. I've seen it in many apps but could not find the appropriate RGB colors: iOS uses it for example in "contacts": http://img98.imageshack.us/img98/9402/image001u.png I'm trying with : bottomLayer.backgroundColor = [[UIColor colorWithRed:80.0/255.0 green:86.0/255.0 blue:97.0/255.0 alpha:1] CGColor]; but it's all whitey. If anyone could get how this popup is designed... Thanks!
