  • Pick an image from the Gallery

    - by Steve Jones
    I have seen a lot of posts about this, and it seems like the code below should work. I have created an SD Card image and added it to the emulator (and that works fine). Intent intent = new Intent(Intent.ACTION_PICK); intent.setType("image/*"); //intent.setAction(Intent.ACTION_GET_CONTENT); startActivityForResult(intent, 1); It does launch and allow selection of images, but when I click on an image, everything exits and the emulator returns to the home screen, not the back to my app. My onActivityResult is never called either. What am I missing?

  • How to set up a database and API web page to accept POST updates from iPhone?

    - by lionfly
    Hi there, I am developing an iPhone app, which now can update Twitter account with GPS coordinates in real-time, by the Twitter API link: http://username:[email protected]/statuses/update.xml , and I am looking at how to make my own database to accept updates from iPhone, via a similar API page. It seems a .php page can serve as the API, and MySQL can serve as the database. What are the good ways of doing it? Any template code and tutorial please?

  • How to schedule heavy work for later display for Listviews?

    - by Pentium10
    I have a listview with 200 items. I use a custom view for each row. There is a code that takes some time to calculate, and because of this the list hangs out on scrolling and loads in slow (2-3sec). I have subclassed SimpleCursorAdapter, and using Filterable and SectionIndexer. I have in mind to show initially the name of the record, and put in a thread the calculation, and will show up later when it's done. How do I push back some work, and later update the listview to include the calculated data? This should show up on fly without user interaction.

  • How to check if Contact has Image?

    - by Pentium10
    I am assigning to an ImageView contacts images using this code: mPhotoView = (ImageView) findViewById(R.id.photo); mPhotoView.setImageURI(objItem.getPhotoUri()); If the contact has no image, this does nothing, and no error is raised. When there is no image, I want to add a default image. So I need to check either if the image was added to the view, or check that the URI holds some image data How do I achieve that? Than I will set default image by this: mPhotoView.setImageResource(R.drawable.ic_contact_picture_2);

  • Recording app sound in iphone

    - by user292127
    Hi, I am developing a music mixing app in iphone. It'll mix the music and user can compose a new music from it. I need to record this final music. I had used AVAudiorecorder to record this one. But no change. It can record sound from microphone but I need to record app sound. I had used audio queue call back function to record the audio. But when app runs I can hear the audio from my app and I couldn't hear any sound from recorded audio. There is no problem with recording since I can hear the audio recorded through microphone. But I need an offline recorder which can record the audio output of iphone, rather than the audio input through microphone. I need a recorder which can record audio using ipod touch (no microphone). Any help?

  • Grouped table with image in first row (and section), the remaining ones having text with different l

    - by Structurer
    Hi I have a grouped table with two sections where I display text with different length and therefore cell height. I have solved the problem with the different length/height with constrainedToSize in cellForRowAtIndexPath. Now I want to add a section with one single row in which I want to show a picture. How should I best implement that? (still a bit of a beginner with the Objective C) I would guess that I would have to create an UIImageView and somehow link that to the cell, but my biggest concern is how do I do with the dequeueReusableCellWithIdentifier now that I will have two different type of cells? Appreciate any advice that will help me save time from trial and error!

  • UIView viewWithTag 0 problem

    - by leon
    Hi, On view in IB I have numerous items (including view itself). ONLY one item has tag 0, yet following line works for ANY UITextBox other then the one with tag 0. Note that only ONE UITextBox has tag 0, why: (UITextField *) [self.view viewWithTag:0]).text = @"foo"; Interesting that when triggered event received for the element with tag 0, I can get value of Tag 0 with no problem. Is there a limitation to look for tag 0 elements?

    - by itai alter
    Hello all, First of all, I'd like to thank the good people who helped me around on this site. Thanks. I'm trying to detect a failed authentication attempt in my app... I'm using the didReceiveAuthenticationChallenge method, and the checking if [challenge previousFailureCount] is equal to 0. The problem is that it's always stays on zero, even if the username and password that I send with the credentials are incorrect. I couldn't find any info about this kind of issue, any help will be much appreciated. Thanks!
