  • How do I set an ABPeoplePickerNavigationController's prompt?

    - by mverzilli
    This is the code I'm using to call the people picker, but the prompt label text doesn't change: ABPeoplePickerNavigationController *picker = [[ABPeoplePickerNavigationController alloc] init]; picker.peoplePickerDelegate = self; picker.displayedProperties = [NSArray arrayWithObjects: [NSNumber numberWithInt:kABPersonEmailProperty], nil]; picker.navigationItem.prompt = @"Choose a contact to..."; [self presentModalViewController:picker animated:YES];

  • iPhone Camera and Image Chooser

    - by PF1
    Hi Everyone: I have found a lot of information on using UIImagePickerController to let the user choose the image they want from the Photos application's data. I am wondering how I can create this same effect on 3.0, as it doesn't seem as if a lot of the old code works anymore. In addition, I would like the user to be able to take a new picture from this same pop-up. Thanks for any help!

  • How do I get Spotlight attributes to display in the get info window?

    - by Alexander Rauchfuss
    I have created a spotlight importer for comic files. The attributes are successfully imported and searchable. The one thing that remains is getting the attributes to display in a file's get info window. It seems that this should be a simple matter of editing the schema.xml file so the attributes are nested inside displayattrs tags. Unfortunately this does not seem to be working. I simplified the plugin for testing. The following are all of the important files. schema.xml <types> <type name="cx.c3.cbz-archive"> <allattrs> kMDItemTitle kMDItemAuthors </allattrs> <displayattrs> kMDItemTitle kMDItemAuthors </displayattrs> </type> <type name="cx.c3.cbr-archive"> <allattrs> kMDItemTitle kMDItemAuthors </allattrs> <displayattrs> kMDItemTitle kMDItemAuthors </displayattrs> </type> GetMetadataForFile.m Boolean GetMetadataForFile(void* thisInterface, CFMutableDictionaryRef attributes, CFStringRef contentTypeUTI, CFStringRef pathToFile) { NSAutoreleasePool * pool = [NSAutoreleasePool new]; NSString * file = (NSString *)pathToFile; NSArray * authors = [[UKXattrMetadataStore stringForKey: @"com_opencomics_authors" atPath: file traverseLink: NO] componentsSeparatedByString: @","]; [(NSMutableDictionary *)attributes setObject: authors forKey: (id)kMDItemAuthors]; NSString * title = [UKXattrMetadataStore stringForKey: @"com_opencomics_title" atPath: file traverseLink: NO]; [(NSMutableDictionary *)attributes setObject: title forKey: (id)kMDItemTitle]; [pool release]; return true; }

  • How to rotate a UIImageView?

    - by jkally
    It's quite frustrating not to be able to do such a simple task: I have an "app" with a single viewcontroller, and in it a single UIImageView, that's initialized to a specific image at potrtait mode. Now when the iPhone gets roteated to landscape mode and the shouldAutorotateToInterfaceOrientation event fires, at which I return YES, my resulting UIImageView looks totally screwed up: either the image is stretched so to fill landscape mode frame (which looks ridiculuous of course) or the top and bottom of the image are cropped. How can I have my UIImageview and the contained image handle the device rotation gracefully, and display normal looking image at landscape mode as well?

  • How to wait until location is completely found? (Core Location)

    - by sudo rm -rf
    Hello. I have a problem within my app. I'm trying to find the user's location to the best preciseness in order to determine their zip-code. Currently I have a button that, when pressed, starts a method named locateMe. -(IBAction)locateMe; { self.locationManager = [[CLLocationManager alloc] init]; locationManager.delegate = self; locationManager.desiredAccuracy = kCLLocationAccuracyBest; [locationManager startUpdatingLocation]; Then I've implemented didUpdateToLocation: -(void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation; { NSLog(@"Found location! %f,%f",newLocation.coordinate.latitude,newLocation.coordinate.longitude); } I had previously done much more complicated stuff in didUpdateToLocation but as I tested some things I realized that the first location it found was not precise in the least. So, I put the NSLog call in there and it gave me an output similar to below... Found location! 39.594093,-98.614834 Found location! 39.601372,-98.592171 Found location! 39.601372,-98.592171 Found location! 39.611444,-98.538196 Found location! 39.611444,-98.538196 As you can see, it first gives me a value which is not correct, which was causing problems within my app because it wasn't giving the correct location. So, here's my question. Is there any way I can wait for the location manager to finish finding the most precise location? Thanks in advance! EDIT: I'm wanting something like this: if (newLocation.horizontalAccuracy <= locationManager.desiredAccuracy) { } But it never gets called!

  • Any simple way to "resize" an NSBezierPath?

    - by d11wtq
    I have an NSBezierPath that I'm filling and stroking. I'd like to add some inner glow to the path (a light stroke, just inside of the outer stroke), and the thing that comes to mind is to use the same path shrunk by 1 pixel (the size of the line that is already )stroked. Is there a way to do this? Alternatively, is there some sort of pattern I can use when applying both a border (stroke) and a glow to a bezier path? Example, the (extremely subtle) inner glow on the Google Chrome tabs:

  • How can I dynamically hide a button from a view?

    - by jpm
    I would like to dynamically hide a button in one of my views, depending on a certain condition. I tried adding some code to the view controller's -viewWillAppear method, to make the button hidden before displaying the actual view, but I still don't know how to do that. I have a reference to the button through an IBOutlet, but I'm not sure how to move forward from here. For reference, this is a UIBarButtonItem instance.

  • iPhone noob - different method types?

    - by codemonkey
    My apologies in advance for what is probably a really dumb question. I'm familiar (or at least getting familiar) with instance and class methods in objective-c, but have also seen method implementations that look like this: #import "Utilities.h" #import "CHAPPAppDelegate.h" #import "AppState.h" @implementation Utilities CHAPPAppDelegate* GetAppDelegate() { return (CHAPPAppDelegate *)[UIApplication sharedApplication].delegate; } AppState* GetAppState() { return [GetAppDelegate() appState]; } @end What are these? While I'm sure this is documented somewhere, I don't know what term to use in searching for an explanation of what's being done here. I like the syntax methods like this let me use when calling them, but I'm not sure exactly what I'm doing, what the implications are, how to send parameters to these types of functions, etc? To clarify how I ended up in this position, I started using these methods in a "utilities" class of mine after reading some online blog describing the author's preference for declaring these functions this way. Now I can't seem to track down a more detailed explanation of what exactly the differences are, etc.

The following image shows the delete button of my program.

  • remove image from tableViewCell created programatically

    - by Ruthy
    Hello, I would like to move an imageView contained on a cell and it works but creating a new image at new position keeping old image (then two are shown). How could I remove old one?? used code: UIImage *cellImage = [UIImage imageNamed:(@"%@", showIconName)]; UIImageView *imageViewToPutInCell = [[UIImageView alloc] initWithImage:cellImage]; imageViewToPutInCell.frame = CGRectMake(iconPos, 7, cellImage.size.width, cellImage.size.height); [cell.contentView addSubview:imageViewToPutInCell]; every time that I reload tableView, it creates a new overlapped image. [cell.contentView removeFromSuperview]; used before, removes it but then new image is not created. Please help!! Thanx

  • 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.

  • When an NSWindow object has a delegate that is a NSWindow subclass, who is responsible to act on received events?

    - by spade78
    So I'm building a program that features the use of the IKImageBrowserView component as a subview in an NSWindow. As a side note, I have a controller object called ImageBrowserController which subclasses NSWindow and is set as the delegate of the NSWindow object of my app. I have sent IKImageBrowserView the message setCanControlQuickLookPanel:YES to enable it to automatically use the QuickLook functionality to preview image files when the IKImageBrowserView is a first responder to receive key events. Then it took me a while to figure out how to make the IKImageBrowserView a first responder which I finally got working by overriding acceptsFirstResponder inside my ImageBrowserController. Now I understand that as the delegate to the NSWindow, ImageBrowserController has a place in the responder chain after the event gets triggered on NSWindow. And I understand that as a subview of NSWindow, IKImageBrowserView is in line to be passed events for event handling. What I don't get is where the connection is between the ImageBrowserController being a first responder and the event somehow making it to the IKImageBrowserView. I didn't set NSWindow or IKImageBrowserView as first responders explicitly. So why isn't it necessary for me to implement event handling inside my ImageBrowserController? EDIT: So after reading the accepted answer and going back to my code I tried removing the acceptsFirstResponder override in my ImageBrowserController and the QuickLook functionality still triggered just like the accepted answer said it would. Commenting out the setCanControlQuickLookPanel:YES made the app beep at me when I tried to invoke QuickLook functionality via the spacebar. I'm getting the feeling that my troubles were caused by user error of XCode in hitting the RUN button instead of the BUILD button after making changes to my code (sigh).

  • Ok to implement backend/shared functionality for iPhone in JavaScript?

    - by John Wright
    Is it ok to use the Webkit Javascript engine to implement cross-platform, non-GUI backend functionality on the iPhone, iPad? In my case, I was interested in re-using Javascript code that I have that works on top of SQLite. I thought I would need to re-implement the logic in Obj-C but perhaps I could just share it and expose some hooks into Obj-C using JSCocoa or straight through JavaScript core. Is this legal per Apple guidelines?

  • EASY: How does one release memory correctly in the attached C array?

    - by Tricky
    Hi, I'm just trying to work out why the following code is leaking memory and I have a funny feeling that i'm not releasing the array memory correctly. This is a C function in a wider objective-c app and I'm not native to C... i've tried just using free() on the array, but have a feeling this isn't the whole story... Could someone have a look and see what I'm missing here. Thanks! CFIndex theNumberOfSettings = 3; CTParagraphStyleSetting theSettings[3] = { {kCTParagraphStyleSpecifierAlignment, sizeof(CTTextAlignment), &alignment}, {kCTParagraphStyleSpecifierLineSpacing, sizeof(lineSpacing), &lineSpacing}, {kCTParagraphStyleSpecifierHeadIndent, sizeof(headIndent), &headIndent} }; CTParagraphStyleRef theParagraphRef = CTParagraphStyleCreate(theSettings, theNumberOfSettings); CFAttributedStringSetAttribute(attrString, CFRangeMake(0, CFAttributedStringGetLength(attrString)-1), kCTParagraphStyleAttributeName, theParagraphRef); CFRelease(theParagraphRef); free(theSettings);

  • How do Apple code level support requests work?

    - by JustinXXVII
    I'm having an issue with a build that I can't figure out, and I'm considering filing a support request. It says I'll get contacted in about 3 days usually. Can anyone explain the process this takes, because I don't want to burn one of these by screwing up! Should I include a zip file of my entire project, or will the source file I'm having issues with be enough? Do I have to be at my computer when they contact me? Thanks for your help, generous ones!
