  • How to change format of date/time?

    - by 4thSpace
    I have this date and time format: 2010-05-19 07:53:30 and would like to change it to: Wednesday @ 7:53PM 5/19/2010 I'm doing this, which gets the current format: NSDateFormatter *formatter = [[NSDateFormatter alloc] init]; formatter.dateFormat = @"yyyy-MM-dd HH:mm:ss"; but when I change the format, I end up with a null. For example: formatter.dateFormat = @"hh:mm tt MM-dd-yyyy"; date = [formatter stringFromDate:formattedDate]; date will be null. I want to put the end result into an NSString. It would be nice if time and date could come out as separate properties so I can arrange them however I like. Any ideas on how I can change the formatting?

  • Mail attachement on iPhone

    - by Infinity
    Hello guys! Is there a way to get the attachements from the Mail app on the iPhone? I've seen some apps which can do it. But how? Can you point me on the right way? I was trying with the MessageUI, but I don't think it is the right way.

  • Can the memory used by MKMapView be released some how?

    - by gdr
    I am using an MKMapView in my iPhone application. When I load this view, the activity monitor instrument shows that the real memory of my App is increasing significantly. It keeps going up as you move the map around or zoom in and out. Once the View controller that loads this view is removed, the memory that was allocated due to the usage of the mapView does not get freed up. Is there something that can be done to get all this memory back?

  • Exception when creating an activity: Could not select item Parcel unable to marshal value

    - by user341652
    Hi, I am trying to call an Activity from another instance of the activity. The code is supposed to be a simple file browser (part of a larger application). I am using a ListActivity, and when an item (such as a folder) is selected, it is supposed to open it up in the new Activity. I have a feeling it is a problem with the AndroidManifest (which just has the basic tag). Any assistance would be appreciated. Thanks, Steve

  • release vs setting-to-nil to free memory

    - by Dan Ray
    In my root view controller, in my didReceiveMemoryWarning method, I go through a couple data structures (which I keep in a global singleton called DataManager), and ditch the heaviest things I've got--one or maybe two images associated with possibly twenty or thirty or more data records. Right now I'm going through and setting those to nil. I'm also setting myself a boolean flag so that various view controllers that need this data can easily know to reload. Thusly: DataManager *data = [DataManager sharedDataManager]; for (Event *event in data.eventList) { event.image = nil; event.thumbnail = nil; } for (WondrMark *mark in data.wondrMarks) { mark.image = nil; } [DataManager sharedDataManager].cleanedMemory = YES; Today I'm thinking, though... and I'm not actually sure all that allocated memory is really being freed when I do that. Should I instead release those images and maybe hit them with a new alloc and init when I need them again later?

  • View controller/NIB architecture for non-navigation application with transitions?

    - by Ben
    I'm tinkering with an app that doesn't use the UINavigation root view control system, so I don't have natural ownership for each app "view". I essentially have two basic views, a document list view, and a document edit view. I'm playing with UIView animation for getting from a selected document to the edit view. I also have a toolbar that exists in both "views". Because I don't have UINavigation running the show for me, I have a tendency to just throw more and more stuff into one NIB and one view controller that owns the whole container. But now I'm trying to figure out how to segue from the document list view to the edit view if the edit view lives inside a different NIB, preserving the toolbar too. Anyone have thoughts or experience on app structures like this? I find the docs lacking on best practices around code/UI structure for anything except trivial one-screen apps or full-on navigation apps. Thanks!

  • Is there an easy way to change iPhone Application Settings from within an application?

    - by Matt
    I've got application settings working just fine. However, I'd like to be able to change my app settings from within my app. It seems as though there should be some kind of generic way to add this functionality to my app without having to recreate all the controls myself. I mean, the code is already written in apple's settings app. Maybe someone wrote this code and open sourced it? (if it is not already available)

  • Android OS 2.2 Permissions: I have absolutely no idea why this simple piece of code doesn't work. Wh

    - by Kevin
    I'm just playing around with some code. I create an Activity and simply do something like this: long lo = currentTimeMillis(); System.out.println(lo); lo *= 3; System.out.println(lo); SystemClock.setCurrentTimeMillis(lo); System.out.println( currentTimeMillis() ); Yes, in my AndroidManifest.xml, I've added: <uses-permission android:name="android.permission.SET_TIME"></uses-permission> <uses-permission android:name="android.permission.SET_TIME_ZONE"></uses-permission> Nothing changes. The SystemClock is never reset...it just keeps on ticking. The error that I'm getting just says that the permission "SET_TIME" was not granted to the program. Protection level 3. The permissions are there...and in the API for 2.2 it says that this feature is supported now. I have no idea what I'm doing wrong. If android.content.Intent; comes into play, please explain. I don't really understand what the idea behind intents! Thanks for any help!

  • Logging to a file on Android

    - by Greg B
    Is there any way of retrieving log messages from an Android handset. I'm building an application which uses the GPS of my HTC Hero. I can run and debug the application from eclipse but this isn't a good use case of GPS, sat at my desk. When I fire the app up when I am walking around, I get an intermittent exception. Is there anyway I can output these exceptions to a text file on the SD card or output calls to Log.x("") to a text file so that I can see what the exception is. Thanks EDIT : Solution Here is the code I finally went with... Thread.currentThread().setUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() { @Override public void uncaughtException(Thread thread, Throwable ex) { PrintWriter pw; try { pw = new PrintWriter( new FileWriter(Environment.getExternalStorageDirectory()+"/rt.log", true)); ex.printStackTrace(pw); pw.flush(); pw.close(); } catch (IOException e) { e.printStackTrace(); } } }); I had to wrap the line pw = new PrintWriter(new FileWriter(Environment.getExternalStorageDirectory()+"/rt.log", true)); in a try/catch as Eclipse would not let me compile the app. It kept saying Unhandled exception type IOException 1 quick fix Sorround with try/catch So I did and it all works which is fine by me but it does make me wonder what Eclipse was on about...

  • Sort NSFetchedResultsController results by user location

    - by cgp
    I have an application that contains some Locations in Core Data, and I want to show them to the user in order of proximity to the user's location. I am using an NSFetchedResultsController to serve the locations to the Table View. I thought about creating a virtual accessor method that returns the location's distance from the user, that would be calculated using a "global" CoreLocationManager, but it crashes with reason: Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'keypath distanceFromCurrentLocation not found in entity < NSSQLEntity Location id=4' I also give the user the option to sort alphabetically, so I would prefer it if I kept the NSFetchedResultsController, if possible. How should I do it? Thanks!

  • Performing selectors on main thread with NSInvocation

    - by kpower
    I want to perform animation on main thread (cause UIKit objects are not thread-safe), but prepare it in some separate thread. I have (baAnimation - is CABasicAnimation allocated & inited before): SEL animationSelector = @selector(addAnimation:forKey:); NSString *keyString = @"someViewAnimation"; NSInvocation *inv = [NSInvocation invocationWithMethodSignature:[workView.layer methodSignatureForSelector:animationSelector]]; [inv setTarget:workView.layer]; [inv setSelector:animationSelector]; [inv setArgument:baAnimation atIndex:2]; [inv setArgument:keyString atIndex:3]; [inv performSelectorOnMainThread:@selector(invoke) withObject:nil waitUntilDone:NO]; I get: *** +[NSCFString length]: unrecognized selector sent to class 0x1fb36a0 Calls: > #0 0x020984e6 in objc_exception_throw > #1 0x01f7e8fb in +[NSObject doesNotRecognizeSelector:] > #2 0x01f15676 in ___forwarding___ > #3 0x01ef16c2 in __forwarding_prep_0___ > #4 0x01bb3c21 in -[CALayer addAnimation:forKey:] > #5 0x01ef172d in __invoking___ > #6 0x01ef1618 in -[NSInvocation invoke] But [workView.layer addAnimation:baAnimation forKey:@"someViewAnimation"]; works fine. What am I doing wrong?

  • iPhone 4.0 Beta compile for 3.1.3

    - by Mark
    I downloaded the iPhone 4.0 Beta. But for my projects I need to compile for 3.1.3 to be able to still submit my projects to the App Store. If I run an old project that isn't a problem I can see all the versions, but when I start a new project I can only pick the 4.0 beta, how can I fix this?
