  • Custom iPhone analytic tool

    - by Ondrej
    Do you think that if I'll build my own custom analytic tool (Flurry, Pinchmedia) and I'll host that on the same server where I have my data source for the application, will Apple consider this as a thirdparty analytic tool or not? ... Problem is that Flurry and Pinch are being banned from Appstore by the newest T&C ... than I thought that I'll build an open source library that will allow anyone to have their own analytic installed on their server ... Thanks, Ondrej

  • UIKeyboard slides from wrong coordinates when in landscape, why?

    - by Horatiu Paraschiv
    Hi I have an app that starts in Landscape Right mode. When I tap a textField the keyboard should slide up, however first time when the keyboard slides it slides from the right (where the home button is). After that it slides up and down as expected. So only the first time when I call the keyboard in it comes from where it would come if the app would be in portrait mode. Does anyone know how can I fix this?

  • NSTimer freezes the app until it gets fired again?

    - by itai alter
    Hello all, I have a simple app with a button, UIImageView and a NSTimer. The timer is fired up every 5 seconds repeatedly to update the ImageView with a new image, while the button simply stops the timer and switches to another View. The problem is that when I press the button, nothing happens for a few seconds (until the timer fires up again). Is there a way to cause the button to stop the timer and do its job at any given time instead of between intervals of the timer? Thanks!

  • Connection

    - by pepersview
    Hello, I would like to ask you about NSURLConnection in objective-c for iPhone. I have one app that needs to connect to one webservice to receive data (about YouTube videos), Then I have all the things that I need to connect (Similar to Hello_Soap sample code in the web). But now, my problem is that I create a class (inherits from NSObject) named Connection and I have implemented the methods: didReceiveResponse, didReceiveData, didFailWithError and connectionDidFinishLoading. Also the method: -(void)Connect:(NSString *) soapMessage{ NSLog(soapMessage); NSURL *url = [NSURL URLWithString:@"http://....."]; NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url]; NSString *msgLength = [NSString stringWithFormat:@"%d", [soapMessage length]]; [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"]; [theRequest addValue: msgLength forHTTPHeaderField:@"Content-Length"]; [theRequest setHTTPMethod:@"POST"]; [theRequest setHTTPBody: [soapMessage dataUsingEncoding:NSUTF8StringEncoding]]; NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if( theConnection ) { webData = [[NSMutableData data] retain]; } else { NSLog(@"theConnection is NULL"); } } But when from my AppDelegate I create one Connection object: Connection * connect = [[Connection alloc] Init:num]; //It's only one param to test. [connect Connect:method.soapMessage]; And I call this method, when this finishes, it doesn't continue calling didReceiveResponse, didReceiveData, didFailWithError or connectionDidFinishLoading. I'm trying to do this but I can't for the moment. The thing I would like to do is to be able to call this class "Connection" each time that I want to receive data (after that to be parsed and displayed in UITableViews). Thank you.

Also how can i index files of these extension for fast search. Any help is appreciated. Thanks.

  • UIDisplayLink stops updating when UIScrollView scrolled

    - by Tricky
    Title is quite self explanatory, but I have some animation being done in a loop triggered by UIDisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill.... Anyway to cancel this behaviour?

  • webOS style view switching on iPhone app

    - by Taylor Satula
    Hello, I have been working with a iPhone app that I would like to have switch views like the Palm Pre does for multitasking. I know the usual way of switching views by using the black bar at the bottom of the app but the app I am working on does not lend itself to having a big black bar in the way (see attached picture #1). I guess my question is, how do I shrink the current view (Current Location window) and show other views on the sides? (see attached picture #2) Then be able to swipe left and right to view other views. I have no idea how to do this and would be eternally grateful if someone could help me out with this. http://www.threepixeldrift.com/images/deep-storage/webOScardapp1.jpg http://www.threepixeldrift.com/images/deep-storage/webOScardapp2.jpg

  • Out-Of-Memory while doing Core Data migration

    - by Kamchatka
    Hello, I'm migrating a CoreData model between two versions of an application. I was storing binary data as blobs in the previous version and I want to take them out of the blobs for performance. My issue is that during the migration it seems that Core Data loads everything into memory which leads to Low Memory Warnings and then to my app being killed. Apple documentation suggests the following : http://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/CoreDataVersioning/Articles/vmCustomizingTheProcess.html#//apple_ref/doc/uid/TP40005510-SW9 However, it seems to rely on the fact that the large objects are applied different mapping. In my case, all the objects are basically the same and the same mapping has to be applied to each of them. I don't see in this case how I could apply their technique. How should I handle a migration with very large objects ?

  • Handle row deletion in UITableViewController

    - by Kamchatka
    Hello, I hava a UINavigationController. The first level is a UITableViewController, the second level just shows details on one of the items of the table view. In this detail view, I can delete the item. It deletes the underlying managed object. When I pop back to the view, I have a crash. I understand why, it's because I didn't update the cached array that contains the data. I looked at several tutorials and I don't exactly understand how am I supposed to handle deletion. Maybe I don't understand exactly where I should fetch the objects in the model. Should I do a query for every cellForRowAtIndexPath and take the item in the result at position indexPath.row? It doesn't look efficient. Should I check for changes somewhere and recache the whole query in an array. I would think CoreData would provide something more natural but I couldn't find it so far. Thanks in advance.

  • UIViewController prevent view from unloading

    - by Ican Zilb
    When my iPhone app receives a Memory warning the views of UIViewControllers that are not currently visible get unloaded. In one particular controller unloading the view and the outlets is rather fatal. I'm looking for a way to prevent this view from being unloaded. I find this behavior rather stupid - I have a cache mechanism, so when a memory warning comes - I unload myself tons of data and I free enough memory, but I definitely need this view untouched. I see UIViewController has a method 'unloadViewIfReloadable', which gets called when the Memory Warning comes. Does anybody know how to tell Cocoa Touch that my view is not reloadable? Any other suggestions how to prevent my view from being unloaded on Memory Warning? Thanks in advance

  • How do I send text to a UITextView?

    - by Lee
    I'm new to iphone development. I'm a VB programmer who is trying to convert a VB application to an ipad app. I need some help with sending text to a UITextView. I want to first have a UIPickerView and then once the user hits a UIButton, a UITextView appears and the text is then generated by my source code code, line by line. The code would constantly be concatenating strings to the text. It would sort of go like this-- 1) User makes selections with UIPickerView. 2) User then hits UIButton. 3) UIPickerView is replaced on the screen with a UITextView. 4) The code does stuff. 5) The code adds the 1st line of text into the UITextView. 6) The code does more stuff. 7) The code then adds the 2nd line of text into the UITextView, retaining the 1st line that was already there. Steps 6 and 7 are repeated until the code is done. Does anyone know of any examples of this that I could look at? I am mostly interested in finding something like a youtube video, a webpage that explains the code or even a good book that covers this particular topic. I am finding that the sample codes that Apple has on this site goes over my head. In fact, I could probably benefit from a good book. But, I am looking for one that I would already know covers this particular topic, since it is so essential to the app that I am trying to build.

  • iPhone App Development - UITableView DetailsView

    - by leo
    Hi, I have a UITableView with a list of items such as item1, item2, item3, item4 and so on. If I select on item1, it will go to the detail view of item1 (which is controlled by DetailsViewController). What I am trying to do is to add a button called "Next" on DetailsView. When clicked, the DetailsView will refresh and show item2. When clicked again, it will show item3 and so on. I have been searching high and low for that to implement. But to no avail. Many thanks in advance!!!

    I have my user preferences set to display in the system-settings application BUT I want to give them the option of adding additional settings. Specifically, the user has a group 'favorites' in the settings bundle and they then can put in the details of their three favorite contacts. However, I want to give the user the option of adding more. I know how to do this with inapp but can this be done through the settings application?
