  • Variable cannot be resolved

    - by Devel
    Hi, I am trying to create an item list, diffrent for each i and j variable. My code is: if (i == 0) { if (j == 0) { final CharSequence[] items = {"4:45", "5:00"} } else if (j == 1) { final CharSequence[] items = {"4:43", "4:58"} } else if (j == 2) { final CharSequence[] items = {"4:41", "4:56"} } else { final CharSequence[] items = {"4:38", "4:53"} } ... new AlertDialog.Builder(this) .setTitle("Hours") .setItems(items, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialoginterface, int i) { // getStation(i); } }) .show(); } I get an error in the line .setItems(items,: items cannot be resolved I think that the compiler thinks that the CharSequence[] items may not be initialised or something... How can I make this programme run?

  • Leak - GeneralBlock-3584

    - by lamicka
    When i try to check leaks of my iPhone App using Instruments, everything is just fine. Same App on actual real device shows this leak for a few times during the app launch. It is pretty non-deterministic and it happens in system libraries. I tried to google down the solution without a luck. Anyone experiencing the same problems? Anyone knows the solution? I find interesting, that every of my leak in code will crash the app sooner or later. These GeneralBlock-3584 leaks keeps app perfectly stable. Might this be reason for AppStore rejection? Thanx for any answer regarding this undocumented problem (Apple is silent unfortunately).

  • wait for CLLocationManager to finish before tweeting

    - by user295944
    I want to wait for latitude.text and longtitude.text to be filled in before sending a tweet, this code works fine, but I would rather not put the tweeting part in locationManager because I also want to sometimes update the current location without sending a tweet. How can I make sure the txt gets filled in before sending the tweet without doing this? - (IBAction)update { latitude.text =@""; longitude.text =@""; locmanager = [[CLLocationManager alloc] init]; [locmanager setDelegate:self]; [locmanager setDesiredAccuracy:kCLLocationAccuracyBest]; [locmanager startUpdatingLocation]; } - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { CLLocationCoordinate2D location = [newLocation coordinate]; latitude.text = [NSString stringWithFormat: @"%f", location.latitude]; longitude.text = [NSString stringWithFormat: @"%f", location.longitude]; TwitterRequest * t = [[TwitterRequest alloc] init]; t.username = @"****"; t.password = @"****"; [twitterMessageText resignFirstResponder]; loadingActionSheet = [[UIActionSheet alloc] initWithTitle:@"Posting To Twitter..." delegate:nil cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; [loadingActionSheet showInView:self.view]; [t statuses_update:twitterMessageText.text andLat:latitude.text andLong:longitude.text delegate:self requestSelector:@selector(status_updateCallback:)]; twitterMessageText.text=@""; }

  • extract data from Plist to array and dictionary

    - by Boaz
    Hi I made a plist that looks like that: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList 1.0.dtd"> <plist version="1.0"> <array> <array> <dict> <key>Company</key> <string>xxx</string> <key>Title</key> <string>VP Marketing</string> <key>Name</key> <string>Alon ddfr</string> </dict> <dict> <key>Name</key> <string>Adam Ben Shushan</string> <key>Title</key> <string>CEO</string> <key>Company</key> <string>Shushan ltd.</string> </dict> </array> <array> <dict> <key>Company</key> <string>xxx</string> <key>Title</key> <string>CTO</string> <key>Name</key> <string>Boaz frf</string> </dict> </array> </array> </plist> Now I want to extract the data like that (all the 'A' for key "Name" to one section and all the 'B' "Name" to other one): NSString *plistpath = [[NSBundle mainBundle] pathForResource:@"PeopleData" ofType:@"plist"]; NSMutableArray *attendees = [[NSMutableArray alloc] initWithContentsOfFile:plistpath]; listOfPeople = [[NSMutableArray alloc] init];//Add items NSDictionary *indexADict = [NSDictionary dictionaryWithObject:[[attendees objectAtIndex:0] objectForKey:@"Name"] forKey:@"Profiles"]; NSDictionary *indexBDict = [NSDictionary dictionaryWithObject:[[attendees objectAtIndex:1] objectForKey:@"Name"] forKey:@"Profiles"]; [listOfPeople addObject:indexADict]; [listOfPeople addObject:indexBDict]; This in order to view them in sectioned tableView. I know that the problem is here: NSDictionary *indexADict = [NSDictionary dictionaryWithObject:[[attendees objectAtIndex:0] objectForKey:@"Name"] forKey:@"Profiles"]; But I just can't figure how to do it right. Thanks.

  • Changing UIView on orientation change

    - by Designeveloper
    Hey all. I have a fairly simple question. I am developing a "rich" iPad app, and I have two background images specifically designed for landscape and portrait. I'd like this ImageView to automatically change depending on the devices orientation. (like pretty much all of Apples iPad apps). Can anyone point me in the right direction? I'm assuming it would be something I do on viewDidLoad..

  • UITableView resizing rows problem

    - by Vin
    Hi All, Hope to get solution to this problem. I have been stuck on it since a long time now. I have a a tableView which has custom labels drawn upon the cell using CGRect. I receive the data from a web service in arrays. Initially i display a line of data on the cells. When the user selects a cell, I call reloadsRowAtIndexPath to increase the height of selected row. In the process, cellForRowAtIndexPath gets called again. I keep track of this by a flag, and when cellForRowAtIndexPath gets called again, I display the two more lines of data from arrays, on the cell. What i am getting is all overlapping data on one other. I tried to remove already placed labels in didSelectRowAtIndexPath, but to no avail. Please help me on this Thanks in advance.

    Hi all, I'm trying to add a Search bar to my UITableView. I followed this tutorial: http://clingingtoideas.blogspot.com/2010/02/uitableview-how-to-part-2-search.html.

  • Stop All Started Services on App Close / Exit

    - by Rad The Mad
    Is it possible to stop all started services when the user hits the Home Button? I use: startService(new Intent(ClassName.this, ClassName2.class)); stopService(new Intent(ClassName.this, ClassName2.class)); This means I will have to somehow add the 'stopService()' for 7+ of my app classes I've researched this topic and I think there's 'onTerminate' but still not sure how this should be implemented. Any help or hints would be appreciated! Thanks!

  • UITableView titleForHeaderInSection prints headers to console twice then crashes

    - by joec
    In the method below titleForHeaderInSection, for some reason the NSLog prints out the headers twice and then the app crashes in objc_msgSend. I can't understand why this would cause the app to crash? It would seem from research that crashes in objc_msgSend are caused by sending messages to already freed objects, but is that the case here? My sectionNames array is populated in viewDidLoad. - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { NSString *title = nil; title=[sectionNames objectAtIndex:section]; NSLog(title); return title; } Thanks

  • Adding view to UIScrollView and toggling scrolling/interacting

    - by Peter Hajas
    Hi all! I have a UIScrollView in my project. I have a view controller I would like to add as a child of the UIScrollview. Would I just do that like this: [scrollView addSubview:theViewController.view]; or is there a better way? (theView is a view, not the TV show) Furthermore, I would like to be able to use a UIButton in scrollView's parent view controller to toggle whether or not the user is scrolling with scrollView and NOT interacting with theView or NOT scrolling with scrollview and interacting with theView. Should I just have that set the property: scrollView.userInteractionEnabled = NO; or would that disable interaction with theView because it's a child? Thanks for your help!

  • Problem with DWR and Android-Browser

    - by moxn
    Hello everyone, I am experiencing a problem with accessing an application from the Android-browser. The application uses DWR to persist connections to the clients that are connected with it. Everything works fine for me, except that if the application does not send any data to the client on the Android-phone for 2 minutes, the connection seems to be lost and no data arrive at the client. The same scenario works just fine on Firefox, Opera and Chrome. If the pause between two data transfers is less than 2 minutes, it works just fine. So, now my question: Is there some timeout setting for the android browser that I am missing? Or is this some built-in bug/feature/whatever that I cannot circumvent? I know that I could prevent this from happening with some sort of heartbeat, I would just like to why this is happening. Thanks in advance, Max btw: Everything (server, clients) runs on my machine and I am testing this on the android emulator with Windows XP Android emulator version 1.10 (build_id CUPCAKE-150240)

  • passing user from UITableView to UIWebView based on selection

    - by ct2k7
    Hello, I'm trying to pass the user on to the interface based on their cell selection in the UITableView, ie, if the user selects cell 1, they are taken to view model 2, containing UIWebView. UIWebView then displays local file, cell1.html. Currently, I've manage to get placeholder using: selectedCellText.text = selectedCell; to display the name of the cell selected. How do I get it to directly pass to the UIWebView, stick UIWebView in the interface and link it using: UIWebView *myWebView = [[UIWebView alloc] initWithFrame:frame]; NSBundle *mainBundle = [NSBundle mainBundle]; NSString *stringUrl = [mainBundle pathForResource:@"selectedCell" ofType:@"html"]; NSURL *baseUrl = [NSURL fileURLWithPath:stringUrl]; NSURLRequest *urlRequest = [NSURLRequest requestWithURL:baseUrl]; [myWebView loadRequest:urlRequest]; My other issue is that some of the cell names have spaces in them, and for simplicity, I'd like to ensure that there are no spaces (actually, will it even work with spaces in the name, I assume with %20 ? Thanks
