  • How to read file.xml from resources to NSString with format?

    - by falkon
    Actually I have such a code: NSString *path = [[NSBundle mainBundle] pathForResource: @"connect" ofType: @"xml"]; NSError *error = nil; NSString *data = [NSString stringWithContentsOfFile: path encoding: NSUTF8StringEncoding error: &error]; NSString *message = [NSString stringWithFormat:data, KEY, COUNTRY_ID]; which reads the connect.xml from resources. But on the formating the string (message) APP quits without displaying any errors. How can I read file.xml from resources to NSString with format?

  • UITextField for Phone Number

    Hello everyone, I was wondering how I can format the textField that I'm using for a phone number (ie like the "Add New Contact" page on the iPhone. When I enter in a new mobile phone, ex. 1236890987 it formats it as (123) 689-0987.) I already have the keyboard set as the number pad. Thanks!

  • Implementing a 30 day time trial

    - by svintus
    Question for indie Mac developers out there: How do I implement a 30-day time trial in a non-evil fashion? Putting a counter in the prefs is not an option, since wiping prefs once a month is not a problem for an average user. Putting the counter in a hidden file somewhere sounds a bit dodgy - as a user I hate when apps sprinkle my hard drive with random files. Any ideas?

  • My table cells don't highlight immediately when touched

    - by Steve Denenberg
    Hi, In my app, I have a table view that has about eight cells. There is a navigation bar at the top. When a user touches a cell, nothing happens for about 1/2 second. Then the touched cell highlights blue and immediately the new view slides into position. The problem is that there is no feedback to the user about which cell he touched until just before the new view slides into position. For example, when I explore the tables in the iPhone's Settings application, when you touch a cell, the cell immediately turns blue, and then there is a 1/2 second delay, and then you see the new view. How do I get my table's feedback of highlighting the cells to happen immediately? I am using tableView didSelectRowAtIndexPath:, and each cell has an accessory button. Thanks for any insight.

  • Singleton Creation preference

    - by cwieland
    You can create singletons in a variety of ways. I am wondering which is better between these. +(ServerConnection*)shared{ static dispatch_once_t pred=0; __strong static id _sharedObject = nil; dispatch_once(&pred, ^{ _sharedObject = [[self alloc] init]; // or some other init method }); return _sharedObject; } I could see that this compiles down to something very fast. I would think that checking the predicate would be another function call. The other is: +(ServerConnection*)shared{ static ServerConnection* connection=nil; if (connection==nil) { connection=[[ServerConnection alloc] init]; } return connection; } Are there any major differences between the two? I know these are probably similar enough to not worry about it. But Just wondering.

  • Should i use a C function or Obj-C Method?

    - by Daniel Granger
    I'm about to create a function which adds to NSDateComponents together is there any advantage to putting this in a C style function or should it go in a Obj-C method? Is there ever a reason to use one rather then the other or should I always stick to Obj-C? BTW: Not that it makes any difference I'm sure but this is for an app on the iPhone Many thanks

  • Which icons/buttons to use for help, about, info?

    - by 4thSpace
    I use the info button to display a settings page. This page is a modal. I need another button from here to display "About" info, since I've already used "info" for something. I have a search form that is accessed only from the modal. On the search form, I need a help icon. I can use the info button but that seems confusing, since I already use the info button from the main view to access the modal. What else can I do for help and about icons/buttons?

  • Putting methods in separate files

    - by Garry
    I have a class (MyClass) with a lot of methods. Consequently, the .m file has become quite difficult to read. I'm relatively new to Objective-C (having come from REALbasic) and I was wondering if it's possible to put some of the methods in MyClass into different files and then include them in the class. How would I go about this in Xcode?

  • Pre-release checklist

    - by bogdansrp
    I built an 10.6+ only app, I tested it in 32-bit and 64-bit mode and everything works (or at least I couldn't find anything wrong). I need help with the actual release build of the app. What settings should I keep an eye out for? Thanks!

  • Setting up an independent delegate?

    - by fuzzygoat
    Its common for the dataSource and delegate to be the same object, its also common for this object to be the viewController. In all the info/tutorials that I have seen online delegates are always setup as above. If I wanted to create my own class instead can anyone give me any pointers as to how I might do that. Where does that object get instantiated, how do you connect the dataSource and delegate items etc. I am using UITableView to test this.

  • iPhone Application

    - by user553627
    Hello, Im working on an iPhone project using xcode and i actually have not programmed using objective-c before. So, my problem mainly is that my app crashes whenever i hit the button that it suppose to show a view of the world map. I think the problem is within the last 2 lines of the code but still i cant figure out why ?!! because whenever i comment out the line "[self presemtM.....]" the program doesn't crash. Would appreciate your help! -(IBAction) pushedGo:(id)sender { CLLocationCoordinate2D coord = {37.331689, -122.030731}; MapViewController *mapView = [[MapViewController alloc] initWithCoordinates:coord andTitle:@"Apple" andSubTitle:@"111"]; [self presentModalViewController:mapView animated:YES] [mapView release]; }
