  • iPhone switching views without first view being reset

    - by user298261
    Heya! I'm making a role-playing game, and I want to have a Map View and a Battle Screen. With the possibility of other screens as well. I thought the best way to achieve this was to use multiple NIB files. When I prototyped this by have one view that creates content, switches to the next view, and then back, the content on the original view was reset. How do I make it so that the first view doesn't reset the data each time it's loaded? Thanks!

    This below is my code, when it gets to the end of the function, the debugger throws an EXC_BAD_ACCESS error and when I check the website's logs, the url was never visited. If anyone could help me fix this issue, it would be greatly appreciated: -(IBAction)submitEmail:(id)sender { NSString *urlStringRaw = [[NSString alloc] init]; urlStringRaw = [NSString stringWithFormat:@"http://vedev.org/AnonMail/sendEmail.php?from=%@&to=%@&subject=%@&body=%@", from.text, to.text, subject.text, bodyContent.text]; NSString *urlString = [urlStringRaw stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; [urlStringRaw release]; NSURL * url = [NSURL URLWithString:urlString]; [urlString release]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [url release]; NSURLConnection *connection = [NSURLConnection connectionWithRequest:requestObj delegate:nil]; [connection release]; [requestObj release]; }

  • iPhone -trouble with a loading data from webservice into a tableview

    - by medampudi
    I am using a Window based application and then loading up my initial navigationview based controller. After loading it if the user is not registered/ does not have a credentials present then it takes the user to a login view controller . loginViewController *sampleView = [[loginViewController alloc] initWithNibName:@"loginViewController" bundle:nil]; [self.navigationController presentModalViewController:sampleView animated:YES]; [sampleView release]; then right after that i try to load the table with data that i get from a webservice using asiHTTP .. for this question lets say it takes 3 seconds time to get the data and then deserialize it . now... my question is it works out okey in the later runs as I store the username and password in a seure location... but in the first instance.... i am not able to get the data to laod to the tableview... I have tried a lot of things... 1. Initially the data fetch methods was in a diffrent methods.. so i thought that might be the problem as then moved it the same place as the tbleviewController(navigationController) 2. I event put in the Reload data at the end of the functionality for the data parsing and deserialization... nothing happens. 3. i did not understand the concept of @property and alll.... 4. The screen is black screen with nothing displayed on it for a good 5 seconds in the consecutive launches of the app.... so could we have something like a MBPorgressHUD implemented for the same. could any one please help for these scenarios and guidance as to what paths to take from here...

  • Best practices and Design Patterns for iPhone forms?

    - by cannyboy
    Part of the app I'm making requires the user to fill in a multi-page form, the contents of which will be saved locally (perhaps using Core Data). Are there any best practices for this? This form just includes text fields. I guess the options are UITextFields, or perhaps a UIWebView, with the fields as part of an html form? Are there are any best practices, or design patterns, which are good for this kind of thing?

  • Best way to display a background with a pattern in an iPhone/iPad app

    - by Dr Dork
    Here's an example of the type of background image I'm talking about... Clearly, there's a pattern in it. My question is, if this were an iPad app and the background image was twice the size, would there be any significant benefits to taking advantage of this pattern by tiling the image? Or would it really make no difference in terms of performance and just be easier to load the entire image into a UIImageView? Thanks in advance for all your wisdom!

  • iPhone animated banner : which framework to use

    - by Julien
    Hi folks, I'm willing to create a little frame to display animated ads in my app. It could be simple little animations, or "3D" transition between ads, or combination of both. I'm not familiar with graphic frameworks, I just used CoreGraphics, which I think is not optimized for that. I thought of OpenGL, but maybe that's too much and takes too much ressources just for this little thing. What do you think ?

  • iphone app hangs in AppDelegate (?)

    - by d_CFO
    No nib/IB, so I've inserted "myAppDelegate" in main and deleted the reference to main.xib in info.plist. Debug continues nicely through all five tab controllers; they seem to have gotten properly loaded into the nav controller. In fact, control passes out of the last "}" in applicationDidFinishLaunching. But there was no (visible) response back at [window addSubview:[tabBarController view]]; and [window makeKeyAndVisible]; statements, much less to the loadView within the first tab (program execution never gets there). The last line is, UIApplication _performInitializationWithURL:sourceBundleID:]. I missed a step? I executed a step improperly?

  • iPhone NSMutableDictionary setObject forKey after initWithContentsOfFile

    - by andrew
    so here's my function + (void) AddAddress:(NSString*)ip:(NSString*)mac { NSMutableDictionary* currentAddresses = [[NSMutableDictionary alloc] initWithContentsOfFile:[self filePath:ADDRESSES_FILE]]; [currentAddresses setObject:mac forKey:ip]; [Configuration Write:currentAddresses]; [currentAddresses release]; } [self filePath:ADDRESSES_FILE] returns a string containing the full path of a file (ADDRESSES_FILE) located in the Documents. The file may not exist, in this case I want to just write an object to the dictionary and then write it down the problem is that when i do setObject forKey it doesn't add anything to the dict (if i just do alloc init to the dict, it works fine, but i want to read the records from the file, if there are any, and replace/add a record by using the AddAddress function)

  • [iPhone app] Detecting which key has been pressed in UITextField

    - by Dough
    Hi, I have an UITextField object in my view and want to launch a method when user press backspace button and textField is empty. First I have to do is to create a cursor storing text length, so when cursor changes from 1 to 0 there is nothing to do. The only way to launch the method is when text length is 0 - press backspace - remain to 0. How to catch the event of pressing the backspace key in my UITextField ? Thanks in advance !

    Is there going to be a way with the 4.0 SDK to create a tool similar to Pandora(which was demoed today), so when the phone is locked, I can manipulate my app? So basically if my app was running, and my phone locks I don't have to unlock the phone to toggle something for the app?
