  • Objects do not retain the frame that I give then when using CGAffineTransforms with Core Animation

    - by user170030
    Hi, I'm making a game where when a card is touched, it grows so that it is focused, and when you 'let go', it goes back to its original size and place. This seems pretty standard, however, when I add cards and move the hand around to accommodate different numbers of cards, touching the card makes it go to its original place, and not to the new place. This has been stumping me for a while now Any hints would be much appreciated. Thanks !

  • Changing Tint / Background color of UITabBar

    - by pixel
    The UINavigationBar and UISearchBar both have a tintColor property that allows you to change the tint color (surprising, I know) of both of those items. I want to do the same thing to the UITabBar in my application, but have found now way to change it from the default black color. Any ideas?

  • How to get orientation of android from gyrsocope sensor events ?

    - by Pritam
    I am using android 2.3 on Nexus S and want to get orientation from gyroscope sensor events. As gyro gives angular velocity how to use this for getting device orientation ? Also is there any way we can get pure linear accelerations on phone's axis, without gravity vector. I expected this from Linear acceleration sensor event but just found a post and referred android source as well for Sensor which currently uses only accelerometer. So what's the best way to combine the readings from both hardware to get pure accelerations without gravity inclusions ? Thanks.

  • Get String Instead of Source - Xcode Cocoa

    - by Kevin
    Hello everyone, I have a program that will scan the contents of a website, and display it in a textbox. The problem is that it shows the html source. For example if my html code was: <html> <body> <p>Hello</p> </body> </html> instead of just showing hello, it'll show the code above... How can I get my objective c program to just read the hello, and not the html source.. I was assuming that it was the encoding when reading the website, but I might be possibly wrong.. I would greatly appreciate it if someone could give me a reasonable answer.. Best Regards, Kevin

    - by sudhakarilla

  • Showing value of UISlider inside App Prefs?

    - by Garrett H
    I have a settings bundle, working perfectly, that I would like to customize a bit. I have, among other things, a PSSliderSpecifier and a PSTitleValueSpecifier. What I would like to do is change the value of the PSTitleValueSpecifier to show the current value of the slider, preferably updating every time the slider's value changes (Actually, what I'd like even more would be displaying the slider's value on the same row as the slider). I know the settings bundle is rather strict about what you're allowed to do in it, but is there any way of doing this?

  • How much difference you find between scrollview offset and contentview offset of table?

    - by neha
    Hi all, In my application, I want to detect the end of the entire table with scrollview. Since there're no sections in my scrollview, I'm using noOfRows*rowHeight to reach the end. I'm using scrollview.contentOffset.y to detect the y offset, but this contentOffset isn't matching the multiplication result i.e. I have 20 rows and with height as 250. So it comes as 5000, but my scrollview.offset.y at the end of last cell is nearly about 4650. What's this difference? Thanx in advance.

  • iPhone Push Notification Reliablity

    - by David Beck
    How reliable do you find push notification on the iPhone to be? Does it improve when moving from the sandbox to production server? I am testing (with the sandbox of course) and have found that notifications are often delayed or not received at all. I am not talking about sending multiple messages and only the last one arriving, as the documentation indicates, but any notification never showing up. Also, I noticed that if I send a notification with an alert, and then send one with just a badge number, that the second notification will close the alert even after it's already opened. Does this happen between apps as well? For instance, if I send an alert for my app, and then the Facebook app sends a badge, will the Facebook badge close my alert window?

  • Core Data and Relationships

    - by alku83
    I have two objects, a Trip and a Place. A Trip represents a journey from one Place to another Place, ie. a Trip needs a fromPlace and a toPlace. So, this is a 1-to-2 relationship, but I need to know which is the "from" and which is the "to". I am not sure how to model this in Core Data. I have created two entities (Trip, Place), and now I want to setup the relationship(s) so I have a fromPlace and a toPlace. Do I need to add an extra field on the Place entity called isFrom, or similar? If this was in a database, I would just have a id column on the Place table, and then two columns in the Trip table - fromPlaceId and toPlaceId. How do I achieve something similar in Core Data?

  • iphone simulator crashes when it tries to access user location

    - by kevin Mendoza
    for some reason my code causes my program to crash. does anyone know why or how to fix it? NSLog(@"here"); CLLocation *location = [locationManager location]; [mapView removeAnnotations:mapView.annotations]; NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; CLLocationCoordinate2D workingCoordinate = [location coordinate]; NSLog(@" this is %@", workingCoordinate.latitude); it makes it to the first NSLog, but somewhere between the first and second it crashes. My guess is that it has to do with the CLLocation *location line.

  • Leak in managedObjectContext save:

    - by Kamchatka
    Hi I have the following piece of code and when I use Instruments/Object Allocations, it tells me that there is a leak there (which goes down to sqlite3MemMalloc). Is there something that I should release? if (![managedObjectContext save:&error]) { NSLog(@"Error while saving."); } The save works well and doesn't trigger an error.

  • Issues declaring already existing NSMutableArray in new class

    - by Graeme
    I have a class (DataImporter) which has the code to download an RSS feed. I also have a view and separate class (TableView) which displays the data in a UITableView and starts the parsing process, storing parsed information in an NSMutableArray (items) which is located in the (TableView) subclass. Now I wish to add a UIMapView which displays the items in the (items) NSMutableArray. Herein lies the issue - I need to somehow get the data from the (items) NSMutableArray into the new (mapView) subclass which I'm struggling with - and I preferably don't want to have to create a new class to download the data again for the mapView class when it already is in the applications memory. Is there a way I can transfer the information from the NSMutableArray (items) class to the (mapView) class (i.e. how do I declare the NSMutableArray in the (mapView) class)? Here's a overview of how the system works: App opened Data downloaded (using DataImporter class) when (TableView) viewDidLoad runs Data stored in NSMutableArray accessible by the (TableView) class And from here I need to access and declare the array from a new (mapView) class. Any help greatly appreciated, thanks. Code for viewDidLoad MapKit: Data *data = nil; NSString *ilocation = [data locations]; NSString *ilocation2 = @"New Zealand"; NSString *inewlString; inewlString = [ilocation stringByAppendingString:ilocation2]; NSLog(@"inewlString=%@",inewlString); if(forwardGeocoder == nil) { forwardGeocoder = [[BSForwardGeocoder alloc] initWithDelegate:self]; } // Forward geocode! [forwardGeocoder findLocation: inewlString]; Code for parsing data into original NSMutable Array: - (void)beginParsing { NSLog(@"Parsing has begun"); //self.navigationItem.rightBarButtonItem.enabled = NO; // Allocate the array for song storage, or empty the results of previous parses if (incidents == nil) { NSLog(@"Grabbing array"); self.datas = [NSMutableArray array]; } else { [datas removeAllObjects]; [self.tableView reloadData]; } // Create the parser, set its delegate, and start it. self.parser = [[DataImporter alloc] init]; parser.delegate = self; [parser start]; }

  • How to prevent modal view controllers flashing when changing

    - by KP Overflow
    I have three view controllers, let's call them A, B and C. When a button is pressed on view A, view B is shown using presentModalViewController:animated: When the finish button is pressed on screen B, it dismisses itself. View A is notified whereupon it immediately shows view C, again using presentModalViewController:animated: The problem is that view A's content is momentarily flashed on the screen between view B closing and view C opening. I can get around this by making view A blank and moving it's current content to a new view, D. (For various reasons, I don't want view B to own view C, that's why it's not opening it) Am I over-complicating this? I'm sure there is a smarter way to go? ThanksT

  • iphone core data loop array and save each

    - by Matt Facer
    I have a core data model with two tables (meal and ingredients). I am trying to save ONE meal with MANY ingredients. I have the code below which loops through an array of ingredients. I'm trying to save it, but I cannot redeclare the "entity" below. How do I do it? I've tried releasing it, but that didn't work! Thanks for any help. for (x=0;x<ingredients;x++) { NSEntityDescription *entity = [NSEntityDescription insertNewObjectForEntityForName:@"Ingredient" inManagedObjectContext:managedObjectContext]; entity.name = @"test"; } (this method does work saving ONE record out of the loop.. so that's not the problem)
