  • The delegate method "clickedButtonAtIndex:" is not called.

    - by sagiftw
    Hello everyone! I have created an alert view with two buttons using the following code: UIAlertView *alertView = [[UIAlertView alloc] initWithTitle: title message: msg delegate:nil cancelButtonTitle:@"Replay" otherButtonTitles:@"Highscore", nil]; [alertView show]; I want to run some code when one of the buttons is clicked. In order to do so, I have added the following method to the delegate.m file: - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex==0) //Run some code else //Other code } But this method is not called when I press either of the buttons! Can someone tell me why? Thanks in advance, Sagiftw

  • when i set property(retain), one "self" = one "retain"?

    - by Walter
    although I'm about to finish my first app, I'm still confused about the very basic memory management..I've read through many posts here and apple document, but I'm still puzzled.. For example..I'm currently doing things like this to add a label programmatically: @property (retain, nonatomic) UILabel *showTime; @sythesize showTime; showTime = [[UILabel alloc] initWithFrame:CGRectMake(45, 4, 200, 36)]; [self.showTime setText:[NSString stringWithFormat:@"%d", time]]; [self.showTime setFont:[UIFont fontWithName:@"HelveticaRoundedLT-Bold" size:23]]; [self.showTime setTextColor:numColor]; self.showTime.backgroundColor = [UIColor clearColor]; [self addSubview:self.showTime]; [showTime release]; this is my current practice, for UILabel, UIButton, UIImageView, etc... [Alloc init] it without self., coz I know this will retain twice.. but after the allocation, I put back the "self." to set the attributes.. My gut feel tells me I am doing wrong, but it works superficially and I found no memory leak in analyze and instruments.. can anyone give my advice? when I use "self." to set text and set background color, does it retain one automatically? THX so much!

  • What happens inside the try block?

    - by dontWatchMyProfile
    Example: @try { // 1) do bad stuff that can throw an exception... // 2) do some more stuff // 3) ...and more... } @catch (NSException *e) { NSLog(@"Error: %@: %@", [e name], [e reason]); } If 1) throws an exception, is the block immediately canceled like a return in a function or a break in a loop? Or will 2) and 3) be processed no matter what happens in 1)?

  • How to access property in sub method after it runs?

    - by Warren
    I'm having a hard time working this one out but I think it should be pretty simple. Basically, I have this method which talks to a webservice and I need to return some data from the sub method, the "authCode". What am I doing wrong? How can I get the authCode out of the manager, or can I create a block or something to to ensure that the manager block runs first? Am I even using the right words - blocks, sub methods??? Please help :) - (NSString *)getAuthCodeEXAMPLE { __block NSString *returnString = @"nothing yet!"; NSURL *baseURL = [NSURL URLWithString:BaseURLString]; NSDictionary *parametersGetAuthCode = @{@"req": @"getauth"}; AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:baseURL]; manager.responseSerializer = [AFJSONResponseSerializer serializer]; [manager POST:APIscript parameters:parametersGetAuthCode success:^(NSURLSessionDataTask *task, id responseObject) { if ([task.response isKindOfClass:[NSHTTPURLResponse class]]) { NSHTTPURLResponse *r = (NSHTTPURLResponse *)task.response; if ([r statusCode] == 200) { self.returnedData = responseObject; NSString *authCode = [self.returnedData authcode]; NSLog(@"Authcode: %@", authCode); returnString = authCode; } } } failure:^(NSURLSessionDataTask *task, NSError *error) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alertView show]; }]; //this currently returns "nothing yet!" return returnString; }

  • iPad --- managedObject problem when [self.tableViewSection reloadData]

    - by user345777
    Hi , I am creating a news aggregator application that fetches a xml feed every 4 minutes. After the xml is loaded, I clear everything by deleting all the objects in the database, then save the new objects back into the database. I then call [self.tableViewSection reloadData]; to reload the tableView. Thats when I get a problem. As soon as the code gets to a section where i access the new [[managedObject valueForKey:@"event_text"] description] content it fails with a : * Terminating app due to uncaught exception 'NSObjectInaccessibleException', reason: 'CoreData could not fulfill a fault for '0x4b3f6a0 '' Now from the flow I described on top, it seems odd to me that the tableView is populated properly the next time i launch the application, with the "new" data I fetched in the previous session. So its not that data thats corrupt , but seems to me something goes wrong when I refetch the managedObject after saving new data. Also keep in mind thats this app runs fine on the iPhone, its the iPad thats is giving me this problem.

  • How to make my iphone app icon update like the weather app icon?

    - by Toret
    I have an application that I'm currently building that requires me to display a visual update on the application it self. example: The weather app displays 14 degrees celcius and some clouds as its application icon. When the weather changes there is an update to the way the icon looks without having to open the weather app. The applications icon changes to reflect the update in weather. You can then open the weather app to get more information if need be. In my application I need to have an update system like that which shows the user information without opening the application. If they would like more information they can open the application then. I have no idea how to accomplish this task at the moment. I hope someone will be able to help or point me in the right direction. Thank you for your time.

  • How do I get intellisense to pop up?

    - by TheLearner
    How do I get intellisense to pop up while I am coding? I know it pops up when I start typing a known type e.g.: if I type NSS it will finish it for me NSString. How do I get it to give me a bunch of options like in Visual Studio e.g.: if I type NS I want to see what my options are like NSString, NSInteger etc? And if I have not typed anything I still want a bunch of options like all the instance variables etc.

  • Adding a Image to UITable View Cell

    - by Graeme
    Hi, I have a table in which I want a dynamic image to load in at the left-hand side. The table needs to use an IF statement to select the appropriate image from the "Resources" folder, and needs to be based upon [dog types]. The [dog types] is extracted from an RSS feed, and so the image in the table cell needs to match the each cell's [dog types] tag. I suspect I need to use - (UIImage *)imageForTypes:(NSString *)types { to do such a thing. Thanks.
