  • iPhone UIImage initWithData fails

    - by DD
    Hello all, I'm trying to code up an async image downloader. I use NSURLConnection to get the data into an NSMutableData and use that data once it is complete to initialize a UIImage. I checked the bytes and it downloads the entire image correctly (right number of bytes at least), however; when I call [UIImage imageWithData:data] and then check the properties of the image, it is zero width and a garbage number for height, in fact, same number no matter what the image is. I tried with bunch of different images, png, jpg, different urls, it always downloads the image completely but UIImage can't initialize with that data. What could I be doing wrong here? Thanks.

  • saving iPhone program state with a deep UINavigationController

    - by jr
    Can someone a good way to save the program state (UINavigationController stack, etc) of an iPhone application. My application obtains a bunch of information from the network and I want to return the person back to the last screen they were on, even if it was 3 or 4 screens deep. I assume that I will need to reload the data from the network along the way as I recreate the UINavigation controllers. I don't necessarily have a problem with this. I'm thinking about maybe having my UINavigationController objects implement some type of protocol which allow me to save/set their state? I'm looking to hear from others who may have needed to implement a similar scenario and how they accomplished it. My application has a UITabbarController at the root and UINavigationController items for each tab bar item. thanks!

    - by sunnycmf

  • VerifyError When Running jUnit Test on Android 1.6

    - by DKnowles
    Here's what I'm trying to run on Android 1.6: package com.healthlogger.test; public class AllTests extends TestSuite { public static Test suite() { return new TestSuiteBuilder(AllTests.class).includeAllPackagesUnderHere().build(); } } and: package com.healthlogger.test; public class RecordTest extends AndroidTestCase { /** * Ensures that the constructor will not take a null data tag. */ @Test(expected=AssertionFailedError.class) public void testNullDataTagInConstructor() { Record r = new Record(null, Calendar.getInstance(), "Data"); fail("Failed to catch null data tag."); } } The main project is HealthLogger. These are run from a separate test project (HealthLoggerTest). HealthLogger and jUnit4 are in HealthLoggerTest's build path. jUnit4 is also in HealthLogger's build path. The class "Record" is located in com.healthlogger. Commenting out the "@Test..." and "Record r..." lines allows this test to run. When they are uncommented, I get a VerifyError exception. I am severely blocked by this; why is it happening? EDIT: some info from logcat after the crash: E/AndroidRuntime( 3723): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 3723): java.lang.VerifyError: com.healthlogger.test.RecordTest E/AndroidRuntime( 3723): at java.lang.Class.getDeclaredConstructors(Native Method) E/AndroidRuntime( 3723): at java.lang.Class.getConstructors(Class.java:507) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping$TestCasePredicate.hasValidConstructor(TestGrouping.java:226) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping$TestCasePredicate.apply(TestGrouping.java:215) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping$TestCasePredicate.apply(TestGrouping.java:211) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.select(TestGrouping.java:170) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.selectTestClasses(TestGrouping.java:160) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.testCaseClassesInPackage(TestGrouping.java:154) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestGrouping.addPackagesRecursive(TestGrouping.java:115) E/AndroidRuntime( 3723): at android.test.suitebuilder.TestSuiteBuilder.includePackages(TestSuiteBuilder.java:103) E/AndroidRuntime( 3723): at android.test.InstrumentationTestRunner.onCreate(InstrumentationTestRunner.java:321) E/AndroidRuntime( 3723): at android.app.ActivityThread.handleBindApplication(ActivityThread.java:3848) E/AndroidRuntime( 3723): at android.app.ActivityThread.access$2800(ActivityThread.java:116) E/AndroidRuntime( 3723): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1831) E/AndroidRuntime( 3723): at android.os.Handler.dispatchMessage(Handler.java:99) E/AndroidRuntime( 3723): at android.os.Looper.loop(Looper.java:123) E/AndroidRuntime( 3723): at android.app.ActivityThread.main(ActivityThread.java:4203) E/AndroidRuntime( 3723): at java.lang.reflect.Method.invokeNative(Native Method) E/AndroidRuntime( 3723): at java.lang.reflect.Method.invoke(Method.java:521) E/AndroidRuntime( 3723): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:791) E/AndroidRuntime( 3723): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) E/AndroidRuntime( 3723): at dalvik.system.NativeStart.main(Native Method)

  • Passing Activity to non-activity object properly

    - by rayman
    In my app ive got a non-activity object which it's role is being a manager class. many times i need to pass "source activity" to methods as parameter to that manager class in order to make some operations on that activity. for exaple let's assume we have MyActivity which gotta do some toast. so i have this manager class called MyManager, and i have this method in it raiseToast(Activity sourceActivity) { Toast.makeText(sourceActivity, demo, Toast.LENGTH_LONG).show(); } and from Myactivity class we calling that method this way: MyManager manager=new MyManager(); manager.raitetoast(MyActivity.this); it works fine. what I'm asking here, is this a proper way to pass an Activity as parameter to a non-activity object? I'm having a memory leaks on real device(not the emulator), I wonder if this could also causing any reason for that? Thanks Idan.

  • How do you get Length of Text in a Mojo TextField?

    - by figus
    How do you get the length of the text inside a Mojo TextField? I'm trying to set a multiLine TextField with a limit of 150 chars, I tried doing it with a counter, but ran into a issue of not being able to decrement the counter when the text was erased, or adding the right number when pasting text, so my new approach was to get the length of the text each time you press a letter. I've already tried this: (gets called in the charsAllow attribute of the textField) if (this.controller.get("mensaje").mojo.getValue().length &lt;= 150) { return true; } this.controller.get("mensaje").mojo.blur(); return false; but it doesn't work.... I debugged and the function exits just after the line in bold... it doesn't even returns true or false. I also tried assigning the length value to a variable or assigning the text to a variable and then get the length, but nothing. It's the same issue. It returns just after the getValue(). Also, maybe because of this issue, the text scrolls instead of wrapping, but when the textField loses focus it wraps the text.

  • How to manage orientation lock in android?

    - by pixel
    I want to create checkbox in my preference Activity that allows user to toggle orientation change. In similar questions people write only about complete orientation lock (by overriding onConfigurationChanged method or adding configChanges in AndroidManifest.xml) or orientation enforcing ( by setRequestedOrientation ). Is there a way to toggle orientation lock?

    - by Manjunath
    Hi all, I am trying to draw custom shapes in iPad application. I am using UIBezierPath for drawing which is available for 3.2 onwards.

  • 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.

  • Dragging an UIView inside UIScrollView

    - by Sergey Mikhanov
    Hello community! I am trying to solve a basic problem with drag and drop on iPhone. Here's my setup: I have a UIScrollView which has one large content subview (I'm able to scroll and zoom it) Content subview has several small tiles as subviews that should be dragged around inside it. My UIScrollView subclass has this method: - (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event { UIView *tile = [contentView pointInsideTiles:[self convertPoint:point toView:contentView] withEvent:event]; if (tile) { return tile; } else { return [super hitTest:point withEvent:event]; } } Content subview has this method: - (UIView *)pointInsideTiles:(CGPoint)point withEvent:(UIEvent *)event { for (TileView *tile in tiles) { if ([tile pointInside:[self convertPoint:point toView:tile] withEvent:event]) return tile; } return nil; } And tile view has this method: - (void)touchesMoved:(NSSet*)touches withEvent:(UIEvent*)event { UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:self.superview]; self.center = location; } This works, but not fully correct: the tile sometimes "falls down" during the drag process. More precisely, it stops receiving touchesMoved: invocations, and scroll view starts scrolling instead. I noticed that this depends on the drag speed: the faster I drag, the quicker the tile "falls". Any ideas on how to keep the tile glued to the dragging finger? Thanks in advance!

  • NSNotification center may not respond to -object ?

    - by blackkettle
    Hi, I'm trying to make simple use of the NSNotification center inside my iPhone application, but I seem to be doing something wrong in this case. I was under the impression that it was possible to retrieve an object associated with a particular message, or at least a reference to the object, but using the following example code I'm getting a warning, "NSNotification center may not respond to -object" - (void)addNewBookmark:(NSNotificationCenter *)notification { Bookmark *newBookMark = (Bookmark *)[notification object]; //Do some stuff with the bookmark object } Indeed, when I compile and run the code, basically nothing I try to do with the contents of the object actually gets carried out - it's simply ignored. The post code is as follows, - (IBAction)save:(id) sender{ //Sending the message with the related object [[NSNotificationCenter defaultCenter] postNotificationName:@"addNewBookmark" object:bookmark]; } and the bookmark object itself is just a dictionary. I also tried using the "userInfo" argument and passing the bookmark object through that, but the result was the same. How should I be doing this? What am I doing wrong?

  • How to add star rating to UITableView cell?

    - by RaYell
    I need to display a bunch of UITableViewCell in my iPhone application. Sample look below. I know how I can enable accessory view and image to UITableView cell but the problem is that I need to add a star rating as visible on the screen. There's no fancy logic behind it, it will just be few images that will be either enabled or disabled. I though that I could create a custom UITableViewCell in NIB but how would I use it in cellForRowAtIndexPath method. If it was just one custom cell I'd just provide an outlet for it and hook it with a property and use it there. But since it would be used multiple times I think I'll need to clone it or copy somehow. What is the simpliest way of adding such stuff to UITableViewCell?

I found this thread http://discussions.apple.com/thread.jspa?threadID=1649012&tstart=0 But am not sure how to implement the code snippet that is given. Is the code implemented as a new class? Also where do I instatiate the NavigationController as I have an application built with the NavigationView template so it is not done in my root controller as per the example

  • forwarding a notification to another class

    - by Mike
    I am using this method - (void)keyboardWillShow:(NSNotification *)notification that is triggered when the keyboard shows. When this method is triggered, it receives a notification that contains several parameters about the keyboard, as the animation duration, animation curve and frame. I need to forward this notification and all its parameters to another class. So, I've tried to do this inside keyboardWillShow: [[NSNotificationCenter defaultCenter] postNotificationName:@"doSomething" object:notification userInfo:nil]; the doSomething notification runs doSomething method on another class, and it has this form: - (void) doSomething:(NSNotification *)notification { but when I try to read the notification values on this other class, using, for example, myRect = [[[notification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue]; I obtain zero for all values. The notification is losing its parameters and not being forwarded. How can I do that? thanks.
