  • How to navigate clicking row to another UITableView ?

    - by Meko
    Hi. I am trying to show detailed UItable view when clicking on row. I used - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; photoListViewController = [[PhotoListViewController alloc]initWithNibName:@"PhotoListViewController" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:photoListViewController animated:YES]; [photoListViewController release]; // [self.navigationController pushViewController:anotherViewController]; // [anotherViewController release]; } This PhotoListViewController is an empty UITableViewController. As I know UITableViewCOntroller has a navigation controller implemented and I don`t have to create navigation controller. But When I clicked on row it does not navigate to second view.AM I have to make some connection on nib file?I only created this PhotoListViewController in File-New-UIViewCOntroller and selected UITableView. EDIT : SOLVED I solved my problem.I should use UINAvigation object.I thought that UITable has it but there was no ))

  • Cross-Page communication in firefox extension

    - by OzBarry
    I have two tabs that my extension uses and I wanted to pass events back and forth between them. I've already developed a Google Chrome extension that does this via the background page api, but there doesn't seem to be an equivalent in firefox. I thought message-manager in the firefox extension docs would do the trick, but the documentation on the object is quite poor. I'd be just as happy with using one of the tabs to control the other if I can't directly import the ideas of a background page from google chrome api. Any help/guidance would be great.

  • iTunes Music Store Link Maker — how to search from within my app?

    - by prendio2
    I'm writing a music reference app and for each album (pulled from last.fm) would like to link to the ITMS (if the album is in the store). iTunes link maker web tool http://apple.com/itunes/linkmaker/ is great for getting links for a known album but I need to access it programatically from within my app. This NSLog blogpost which is from 2003 but was referenced more recently in another question here seems to offer the only solution I've come across so far, suggesting to submit a query to: phobos.apple.com/WebObjects/MZSearch.woa/wa/advancedSearchResults? Put "itms://" before it and the link will work in iTunes, put "http://" before it and the link will work in Camino (Safari sometimes spits back a malformed XML error). The tags that are of importance are as follows: songTerm - song title artistTerm - artist name albumTerm - album name composerTerm - composer name term - all fields The suggestion is that would using http:// rather than itms:// the server will return an XML document of results instead of opening iTunes but either way I am sent directly to iTunes. Is it possible to get back a list of results?

  • Opening Another Xib form an Xib

    - by Goods
    Not a Noob as yesterday, but still green. I have been playing around with the code that Elisabeth Robson has put together HERE. I have a UITabbarcontoller and a IUNavigationController they seem to work fine. I have a UITableviewController to which I loads my NSMutable array. The user clicks a cell and didSelectRowAtIndexPath xib is loaded onto the stack. I put a 'Learn More' button on the current xib(BookDetailView). I've tried a few approaches to load a newer xib when the 'Learn More' button is pressed but have failed. Ive Tried IBAction and Pushing the Newer xib to the top. Do I need to create another view controller? Thanks for looking.

  • Core Audio on iPhone - any way to change the microphone gain (either for speakerphone mic or headpho

    - by Halle
    After much searching the answer seems to be no, but I thought I'd ask here before giving up. For a project I'm working on that includes recording sound, the input levels sound a little quiet both when the route is external mic + speaker and when it's headphone mic + headphones. Does anyone know definitively whether it is possible to programmatically change mic gain levels on the iPhone in any part of Core Audio? If not, is it possible that I'm not really in "speakerphone" mode (with the external mic at least) but only think I am? Here is my audio session init code: OSStatus error = AudioSessionInitialize(NULL, NULL, audioQueueHelperInterruptionListener, r); [...some error checking of the OSStatus...] UInt32 category = kAudioSessionCategory_PlayAndRecord; // need to play out the speaker at full volume too so it is necessary to change default route below error = AudioSessionSetProperty(kAudioSessionProperty_AudioCategory, sizeof(category), &category); if (error) printf("couldn't set audio category!"); UInt32 doChangeDefaultRoute = 1; error = AudioSessionSetProperty (kAudioSessionProperty_OverrideCategoryDefaultToSpeaker, sizeof (doChangeDefaultRoute), &doChangeDefaultRoute); if (error) printf("couldn't change default route!"); error = AudioSessionAddPropertyListener(kAudioSessionProperty_AudioRouteChange, audioQueueHelperPropListener, r); if (error) printf("ERROR ADDING AUDIO SESSION PROP LISTENER! %d\n", (int)error); UInt32 inputAvailable = 0; UInt32 size = sizeof(inputAvailable); error = AudioSessionGetProperty(kAudioSessionProperty_AudioInputAvailable, &size, &inputAvailable); if (error) printf("ERROR GETTING INPUT AVAILABILITY! %d\n", (int)error); error = AudioSessionAddPropertyListener(kAudioSessionProperty_AudioInputAvailable, audioQueueHelperPropListener, r); if (error) printf("ERROR ADDING AUDIO SESSION PROP LISTENER! %d\n", (int)error); error = AudioSessionSetActive(true); if (error) printf("AudioSessionSetActive (true) failed"); Thanks very much for any pointers.

  • How to declare NSString constants for passing to NSNotificationCenter

    - by synic
    I've got the following in my .h file: #ifndef _BALANCE_NOTIFICATION #define _BALANCE NOTIFICATION const NSString *BalanceUpdateNotification #endif and the following in my .m file: const NSString *BalanceUpdateNotification = @"BalanceUpdateNotification"; I'm using this with the following codes: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updateBalance:) name:BalanceUpdateNotification object:nil]; and [[NSNotificatoinCenter defaultCenter] postNotificationName:BalanceUpdateNotificatoin object:self userInfo:nil]; Which works, but it gives me a warning: Passing argument 1 of 'postNotificationName:object:userInfo' discards qualifiers from pointer target type So, I can cast it to (NSString *), but I'm wondering what the proper way to do this is.

  • UIScrollView resizes when a UIViewController is pushed in UINavigationController. Why?

    - by user210504
    Hi! When I push a UIViewController within a UINavigationController, the UIScrollView in the view changes dimensions. Now even I am trying to resize the UIScrollView. It wont simply resize. It maintains the framework dimensions. Any idea why this would be happening. Example: My NIB has a view which has a scrollview with dimensions (320, 430) now when I push the UIViewController associated with the view the scrollview still shows dimensions has 320, 430, but is drawn much smaller then 320,430 Any suggestions in this regard.

  • Capture Backspace , is this a OK solution?

    - by f0rz
    Hello, I having a hard time to capture the backspace button in a UITextView. I am trying to capture it in the method - (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text I thought it was ok to do like this. if([text isEqualToString:@"\b") { // code ... } But for some reason, when backspace is pressed 'text' is empty. I know I can compare lenght of the UITextView but it isnt what I want to achieve. So I found a solution to this. If I look at '[text lenght]' every key on the defaultkeyboard returns 0 . Every key excepts the backspace wich is 0. In that way i know when backspace is pressed. I do this check. if([text lenght] == 0) { // BACKSPACE PRESSED   } What is your opinion about this? -or can I do it in a better way? Regards. - Martin

  • How to ask UIImageView if MultipleTouchEnabled is "YES"

    - by Rob
    I have created a few UIImageViews programmatically, but I have a feeling that even though I setMultipleTouchEnabled to YES during the setup, it is not getting set properly and it's leading to multi-touch issues. My question is, within touchesBegan how do I go about asking the UIImageView that was touched if it has MultipleTouchEnabled or not? I am fairly new to this so I'm really stumbling through code and learning as I go (with your help of course). Thank you ahead of time!

  • Android Keep Activity from Dieing

    - by GuyNoir
    The main Activity I use in my Android application uses a fair amount of memory, meaning that on a less powerful phone, it is susceptible to being killed off when not at the front. Normally this is fine, but it also happens when I am still inside my application, but have a different activity at the top of the stack (such as a preference activity). Obviously it's a problem if my application is killed while the user is still running it. Is there any way to disable the OS's ability to kill off the application for low memory problems? Thanks.

  • Forwarding first responder to UIScrollView unsuccessful

    - by Winston
    Hello, I am trying to create an image cropping bpx whereby the underlying image can be zoomed an scrolled while the cropping "maskview" layer stays the same and the corners can be dragged in any direction. To achieve this, the ImageView is added to a UIScrollView, and this is added to the SelectionViewController.view . I then add the cropping "maskview" layer to the SelectionViewController.view. I did this instead of adding to the scrollview so that the cropping maskview won't be expanded when the underlying image expands. @interface SelectionViewController : UIViewController <UIScrollViewDelegate> { UIImageView *photoview; // Added to self.scrollview MaskedView *maskedview; // Added to self.view UIScrollView *scrollview; // Added to self.view } The maskview has first responder status and responds accordingly. However, the only event I am interested in the maskview is if any of the corners are dragged (this works fine). The problem I want to try to solve is two-fold: If it is a pinch or zoom gesture, I am trying to forward the responder to the UIScrollview using: [self.nextResponder touchesMoved:touches withEvent:event]; The scrollview does not seem to respond. I have confirmed that the self.nextResponder after the maskedview is the SelectionViewController's view itself. From there, it doesn't seem like the UIScrollview responds. It does respond fine if I remove the cropping maskedview. If I zoom in on the underlying image and the cropping maskview rectangle is still the same, I want to now crop the actual zoomed image. Let's say for the upper left hand corner of the crop box, how can I find what the coordinates translates to in the underlying UIImageView now that the image has been zoomed? Any insight into either of these questions would be appreciated. Thank you, Winston

  • Convert bitmap image information into CGImage in iPhone OS 3

    - by giftederic
    I want to create a CGImage with the color information I already have Here is the code for converting the CGImage to CML, CML_color is a matrix structure - (void)CGImageReftoCML:(CGImageRef *)image destination:(CML_color &)dest{ CML_RGBA p; NSUInteger width=CGImageGetWidth(image); NSUInteger height=CGImageGetHeight(image); CGColorSpaceRef colorSpace=CGColorSpaceCreateDeviceRGB(); unsigned char *rawData=new unsigned char[height*width*4]; NSUInteger bytesPerPixel=4; NSUInteger bytesPerRow=bytesPerPixel*width; NSUInteger bitsPerComponent=8; CGContextRef context=CGBitmapContextCreate(rawData, width, height, bitsPerComponent, bytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast | kCGBitmapByteOrder32Big); CGColorSpaceRelease(colorSpace); CGContextDrawImage(context, CGRectMake(0, 0, width, height), image); CGContextRelease(context); int index=0; for (int i=0; i<height; i++) { for (int j=0; j<width; j++) { p.red=rawData[index++]; p.green=rawData[index++]; p.blue=rawData[index++]; p.alpha=rawData[index++]; dest(i,j)=p; } } delete[] rawData; } Now I want the reverse function, which converts CML into CGImage. I know all the color and alpha information to create the image, which stored in the matrix CML, but how can I do that?

  • CGContextSetRBStrokeColor to replace, not add, for alpha?

    - by Peter Hajas
    I use CGContexts to allow the user to draw in my application, here's an example: CGContextSetLineCap(UIGraphicsGetCurrentContext(), kCGLineCapRound); CGContextSetLineWidth(UIGraphicsGetCurrentContext(), size); CGContextSetRGBStrokeColor(UIGraphicsGetCurrentContext(),r,g,b,a); I want the user to have an "eraser" tool that actually erases - it can't draw white (that would add white to the image, which may not have a white background) or alpha (or else the stroke won't do anything). Is there a way to do this? Perhaps replacing contents of a CGContext or UIImage?

  • Disabling home button on iPhone/iPad

    - by alku83
    First of all, I'm completely aware that doing this will get my app rejected by Apple, that it's a poor user experience, and so on. My question is fairly simple, is there a way using private APIs to disable the home button? The aim is to effectively put an iPad into kiosk mode.

  • iPhone OpenGL and NSTimer issues

    - by Kyle
    I have an NSTimer that runs at 60hz. With an OpenGL scene loaded and rendering, my game can get 60fps, solid, all day long.. Then if I go and recompile the app, or reload it, it will get 40fps. Same resources loaded. I've been running into this problem for years, and I just want to know why. It's crazy, and I want to know if I should just abandon this stupid Timer. Conditions are not different on my 3GS between loads. It will just get 40fps sometimes. Obviously the clockrate is not different between loads, so the performance figures should be constant given a constant scene. Here is a log of my framerates: A good load: :-) FrameRate: 61 FrameRate: 61 FrameRate: 61 FrameRate: 60 FrameRate: 60 FrameRate: 61 FrameRate: 60 FrameRate: 60 FrameRate: 61 FrameRate: 60 FrameRate: 61 Now, I'll go ahead and do nothing, recompile, and run: FrameRate: 43 FrameRate: 50 FrameRate: 45 FrameRate: 48 FrameRate: 40 FrameRate: 45 FrameRate: 42 FrameRate: 41 FrameRate: 42 FrameRate: 44 FrameRate: 41 FrameRate: 46 ^- Massive difference visually. What the flying heck could cause this? SAME area of the scene, SAME camera setup. No variables are different.
