  • How do I animate a UIButton in a UITableView?

    - by Ryan Lopez
    I currently have a UITableView with each cell containing four UIButtons. I am placing an image for each button with a downloaded picture from online. I'd like to have the button fade in when the image is finished downloading. I know I can animate in the viewDidLoad, but I assign the image in the cellForRowAtIndex function. How do I go about animating just the UIButton at a later point in time when I update the UIButton with the image?

  • 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.

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

    - by fuzzygoat
    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

  • XCode Obj-C: Make new NSArray from one key each out of an Array of Dictionaries

    - by user323772
    This actually could be a multipart question. But here's the first part ... I have an array (actually in a plist) of dictionaries. Each dictionary has 3 keys in it: (title), (points), and (description). I am trying to make a NEW array with the values of the key "title" from each dictionary in that first array. Let me explain WHY I am doing this and maybe that will provide a better all around explanation. I am trying to let people pick from a pre-determined list. Heck, if this was a web page it would be very simple since all I really care about are the "points" and the "Title". On a web site I could simply do a drop down combo-box with the "points" being the value and the title being the text for each row. But this is not a web page. So what I am trying to do here is pop out a modal picker when they click the text field. The modal picker shows the alphabetical ordered "titles" from our new array. And whichever one they select, it closes the modal view and assigns that "title" text to the UITextField which cannot be edited by the user. I have some code to get my modal picker to pop out. But I need to feed it an array of just the "titles" of each dictionary in my real array. Thanks in advance (and yes I am a newbie)

  • 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?

  • 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?

  • 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?

  • 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.

  • 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.

  • 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

  • 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 ?

  • Public class: Makes pointer from integer without cast

    - by meridimus
    I have written a class to help save and load data for the sake of persistence for my iPhone application but I have a problem with some NSUIntegers that I'm passing across. Basically, I have the code to use pointers, but eventually it has to start out being an actual value right? So I get this error warning: passing argument 1 of 'getSaveWithCampaign:andLevel:' makes pointer from integer without a cast My code is laid out like so. (Persistence is the name of the class) NSDictionary *saveData = [Persistence getSaveWithCampaign:currentCampaign andLevel:[indexPath row]]; Here's Persistence.m #import "Persistence.h" @implementation Persistence + (NSString *)dataFilePath { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; return [documentsDirectory stringByAppendingPathComponent:kSaveFilename]; } + (NSDictionary *)getSaveWithCampaign:(NSUInteger *)campaign andLevel:(NSUInteger *)level { NSString *filePath = [self dataFilePath]; if([[NSFileManager defaultManager] fileExistsAtPath:filePath]) { NSDictionary *saveData = [[NSDictionary alloc] initWithContentsOfFile:filePath]; NSString *campaignAndLevelKey = [self makeCampaign:campaign andLevelKey:level]; NSDictionary *campaignAndLevelData = [saveData objectForKey:campaignAndLevelKey]; [saveData release]; return campaignAndLevelData; } else { return nil; } } + (NSString *)makeCampaign:(NSUInteger *)campaign andLevelKey:(NSUInteger *)level { return [[NSString stringWithFormat:@"%d - ", campaign+1] stringByAppendingString:[NSString stringWithFormat:@"%d", level+1]]; } @end
