  • Looping the layout that was set up in Interface Builder

    - by Slavenko
    I just need for someone to point me in the right direction of how I should be doing things. I wanted to make an iOS news like app that would have interface resembling Windows Phone. Large and small image tiles that represent one news item each. Now I was thinking to create some basic layout in storyboard, that would consist out of, for example, a title, and a 3 different sized tiles/images (the gray part on the attached image). Now, I would be getting the data as a JSON array that has holds different news categories so I was wondering if somehow the set up layout could be reused in a for loop since the layout will only repeat itself (the red part on the attached image) and oly the data would be different. Can this be done, should I even try doing something like this, or should I try to create an entire layout programmatically? I wouldn't mind doing it programatically, it's just that I don't have much experience in creating layouts that way, and wanted to make sure that I don't do something that I might regret later. Thank you for any help and advice.

  • subview is not added immediately (iphone)

    - by Jonathan
    When the return button on the keyboard for a textfield is tapped I want to add a UIView, then connect to a website with NSURlConnection sendsynchronousrequest and I have the code in that order But when I run in the simulator (I can't run on device) the connection is run first then the subview is added (ie the opposite of the order of the code) Why is this and how can stop it, because I want the view to added, then the connection done and then the view removed.

  • What is the best way to implement a Server-Client connection between an iPad and multiple iPhones?

    - by Infinite
    Based on a college-project I'm trying to realize a relatively simple game (Poker) where an iPad acts as Server and multiple iPod-Touchs connect to it as Clients. Gamekit seems to drop out, since those old ipod-touch-devices don't have bluetooth-support. Are there already some Frameworks out there simplifying the process, or do I have to fall back on TCP-Streaming-Sockets and implement it myself?

  • Issue Displaying/Hiding Views (Obj-C iPhone Programming)

    - by roswell
    All right all, So I've got a UITableView that is inited in applicationDidFinishLaunching like so: [self showForumList]; Said method does this: -(void)showForumList { ForumList *fl = [ForumList alloc]; [fl initWithNibName:@"ForumList" bundle:[NSBundle mainBundle]]; self.ForumList = fl; [window addSubview:[self.ForumList view]]; [fl release]; }where self.ForumList is previously defined in the interface as ForumList *ForumList;, etc. Now, in ForumList (itself an extension of UITableViewController obviously), I've got didSelectRowAtIndexPath: -- within it I have the following code: Forum *f = [Forum alloc]; NSArray *forums = [f getForumList]; NSDictionary *selectedForum = [forums objectAtIndex:[indexPath row]]; NSString *Url = [selectedForum objectForKey:@"url"]; NSString *Username = [selectedForum objectForKey:@"username"]; NSString *Password = [selectedForum objectForKey:@"password"]; NSLog(@"Identified press on forum %@ (%@/%@)", Url, Username, Password); [self.globalDelegate showForumListFromForumUsingUrl:Url username:Username password:Password]; [self.globalDelegate closeForumList]; NSLog(@"ForumListFromForum init"); Both of the NSLog calls in this function are executed and perform as they should. Now, here is where the issue starts. self.globalDelegate is defined as AppDelegate *globalDelegate; in the Interface specification in my header file. However, [self.globalDelegate showForumListFromForumUsingUrl:username:password] and and [self.globalDelegate closeForumList] are never actually called. They look like so: -(void)closeForumList { NSLog(@"Hiding forum list"); [[self.ForumList view] removeFromSuperview]; } -(void)showForumListFromForumUsingUrl:(NSString *)Url username:(NSString *)Username password:(NSString *)Password { NSLog(@"Showing forum list from forum"); ForumListFromForum *fl = [ForumListFromForum alloc]; [fl initWithNibName:@"ForumListFromForum" bundle:[NSBundle mainBundle]]; [fl initFromForumWithUrl:Url username:Username password:Password]; self.ForumListFromForum = fl; [window addSubview:[self.ForumListFromForum view]]; [fl release]; } The app does not respond to my press and neither of these NSLog calls are made. Any idea where I've gone wrong?

  • Loading an image sequence in InterfaceBuilder -ObjectiveC

    - by eco_bach
    Hi Using Actionscript and or in the Flash IDE you can either instantiate bitmaps from the library, or simply import bitmaps into the timeline of a MovieClip to create an image sequence. How would you do the same thing in InterfaceBuilder and-or using ObjectiveC? Do I need to create a new view for each and every image?

  • Adding text labels to sliders in iPhone Settings application

    - by Kevin L.
    When configuring a Settings.bundle as part of an iPhone application bundle, it's trivial to add minimum and maximum value images to sliders (PSSliderSpecifier), but not simple maximum and minimum text labels. http://developer.apple.com/iPhone/library/documentation/PreferenceSettings/Conceptual/SettingsApplicationSchemaReference/Articles/PSSliderSpecifier.html iPhone gurus: Is anyone aware of a simple means to apply text labels to these sliders for use within the Settings application (therefore, no slider subclassing shenanigans; it all has to be done via a plist)? I suppose I could just use an image of the label but...ew. Bonus points if there's a way to show the current value of a slider in some sort of number format.

  • Syntax highlighting on iPhone Text-Editor

    - by pbcoder
    Hi, I want to write a simple text editor for iPhone with syntax highlighting support for c,c++. But the problem is, I dont't know how to do this. The first solution I was thinking about, was to go over the text and highlight keywords when the value of the UITextView has changed, but I think that if I got more than 1000lines of code that doesn't work very well. Thanks for help!

  • Using a Data Management Singleton

    - by Dan Ray
    Here's my singleton code (pretty much boilerplate): @interface DataManager : NSObject { NSMutableArray *eventList; } @property (nonatomic, retain) NSMutableArray *eventList; +(DataManager*)sharedDataManager; @end And then the .m: #import "DataManager.h" static DataManager *singletonDataManager = nil; @implementation DataManager @synthesize eventList; +(DataManager*)sharedDataManager { @synchronized(self) { if (!singletonDataManager) { singletonDataManager = [[DataManager alloc] init]; } } NSLog(@"Pulling a copy of shared manager."); return singletonDataManager; } So then in my AppDelegate, I load some stuff before launching my first view: NSMutableArray *eventList = [DataManager sharedDataManager].eventList; .... NSLog(@"Adding event %@ to eventList", event.title); [eventList addObject:event]; NSLog(@"eventList now has %d members", [eventList count]); [event release]; As you can see, I've peppered the code with NSLog love notes to myself. The output to the Log reads like: 2010-05-10 09:08:53.355 MyApp[2037:207] Adding event Woofstock Music Festival to eventList 2010-05-10 09:08:53.355 MyApp[2037:207] eventList now has 0 members 2010-05-10 09:08:53.411 MyApp[2037:207] Adding event Test Event for Staging to eventList 2010-05-10 09:08:53.411 MyApp[2037:207] eventList now has 0 members 2010-05-10 09:08:53.467 MyApp[2037:207] Adding event Montgomery Event to eventList 2010-05-10 09:08:53.467 MyApp[2037:207] eventList now has 0 members 2010-05-10 09:08:53.524 MyApp[2037:207] Adding event Alamance County Event For June to eventList 2010-05-10 09:08:53.524 MyApp[2037:207] eventList now has 0 members ... What gives? I have no errors getting to my eventList NSMutableArray. But I addObject: fails silently?

  • Using [self method] or @selector(method)?

    Can anyone enlighten me as to the differences between the two statements below. [self playButtonSound]; AND: [self performSelector:@selector(playButtonSound)]; I am just asking as I had some old code that used @selector, now with a little more knowledge I can't think why I did not use [self playButtonSound] instead, they both seem to do the same as written here. gary

  • iPhone - In App Purchase questions

    - by diwup
    Hey guys, Merry Christmas. I have two questions on In App Purchase. iAP application process: do I need to submit my iAP items applications, wait for Apple's responses, then build my app accordingly, or, I can just create some iAP items, build them into my app, then after everything's done, submit my binary to Apple? Intermediary currency: on Apple's documentation I found these sentences: "You may not offer items that represent intermediary currency because it is important that users know the specific good or service that they are buying." However, I found a few apps on the App Store offering its users with different kinds of intermediary currency. I'm confused. Is this a gray area in which we developers can play some tricks? Thanks in advance. Di

  • How do I run modals windows from code with cocoa?

    - by Leandro
    Hi,everybody I`m trying to run a window as modal directly from the code. My program starts and a main NSWindows is showed.A thread still running to see if the user has a valid distribution. if he doesn't I need to run a modal.I mean, I have no buttons clicked in the interface.I've designed a NSWindow on the interface builder for a password set, and I want to call it only when my validation is not successful. I have tested and realized that these methods which are responsible for modal windows running only work in a IBAction environment. //This doesn't work -(void) showPasswordWindow { [NSApp runModalForWindow:[self window]]; } //this works But its not useful for me =( - (IBAction) passwordWindowButton:(id)sender { [NSApp runModalForWindow:[self window]]; } Please, help this newbie =)

Anyone's help will be much Appreciated. Thank you, Monish.

  • iPhone Application failing to come back from sigkill

    - by overscore
    I have no idea if this is intended behaviour, but whenever the application exits (say, the user is double-clicking the home button and pressing on the red dash on the icon) I get the dreaded SIGKILL. Now, when I try to launch the app again all I get is the old screen state and a frozen (I presume ?) program. It could be because of clunky memory management, but NSZombieEnabled doesn't seem to agree. Any thoughts ?

  • Why do they initialize pointers this way?

    - by Rob
    In almost all of the books I read and examples I go through I see pointers initialized this way. Say that I have a class variable NSString *myString that I want to initialize. I will almost always see that done this way: -(id)init { if (self = [super init]) { NSString *tempString = [[NSString alloc] init]; myString = tempString; [tempString release]; } return self; } Why can't I just do the following? -(id)init { if (self = [super init]) { myString = [[NSString alloc] init]; } return self; } I don't see why the extra tempString is ever needed in the first place, but I could be missing something here with memory management. Is the way I want to do things acceptable or will it cause some kind of leak? I have read the Memory Management Guide on developer.apple.com and unless I am just missing something, I don't see the difference.

  • floats in NSArray

    - by JordanC
    I have an NSArray of floats which I did by encapsulating the floats using [NSNumber numberWithFloat:myFloat] ; Then I passed that array somewhere else and I need to pull those floats out of the array and perform basic arithmatic. When I try [myArray objectAtIndex:i] ; The compiler complains that I'm trying to perform arithmatic on a type id. It also won't let me cast to float or double. Any ideas? This seems like it should be an easy problem. Maybe it will come to me after another cup of coffee, but some help would be appreciated. Thanks.
