  • How to set UITableView to Grouped?

    - by 4thSpace
    In an iPhone navigation based app, I want to add a second tableview but have its design available in IB. I've added a new empty XIB and dragged a UITableView onto it. I want to setup the layout through IB. I've created a controller for this tableview and set the File's Owner class in IB to this controller. I linked the tableview to File's Owner as well. I set the tableview to grouped in IB. However, that does not translate at runtime. I still have a plain tableview. In fact, none of the Inspector settings work at runtime. What have I missed?

    - by crackedsun
    I'm developing an app in which i need the TCP connection to stay alive. I've implemented a kind of ping/pong system to do this. It works perfectly when the screen is on, but when it goes of the phone stops responding to the pings after a while. I've created a Wi-Fi wake lock but i'm still experiencing still the same problem.. Any ideas?

  • How do I get the users location latitude and longitude?

    - by kevin Mendoza
    I need to access the users location in this method contained in the mainViewController -(void)loadAnnotations{ [mapView removeAnnotations:mapView.annotations]; CLLocationCoordinate2D workingCoordinate; workingCoordinate.latitude= //here i need the users latitude workingCoordinate.longitude= //here i need the users longitude NSLog(@" this is %@", workingCoordinate.latitude); iProspectLiteAnnotation *tempMine = [[iProspectLiteAnnotation alloc] initWithCoordinate:workingCoordinate]; [tempMine setTitle:@"Present Location"]; [tempMine setAnnotationType:iProspectLiteAnnotationTypeUser]; [mapView addAnnotation:tempMine]; } however the mainViewController is already set to <fipsideViewControllerDelegate> What should I add to the header file and the implementation file to poll the location Manager for the users current latitude and longitude?

  • What's wrong with this addProximity code?

    - by Pentium10
    I have this code: private void setupProximity() { Intent intent = new Intent(this, viewContacts.class); PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent, 0); LocationUtils.addProximity(this, -37.40, 144.55, 1000, 1000000, sender); } public static void addProximity(Context ctx,double lat, double lon, float rad,long exp, PendingIntent pintent) { LocationManager lm = (LocationManager) ctx.getSystemService(Context.LOCATION_SERVICE); lm.addProximityAlert(lat, lon, rad, exp, pintent); } Why I don't get the class to fire up? I am in the range of the zone.

  • How to do orientation rotation like built-in Calc app?

    - by Ray Wenderlich
    I'm trying to make an app that handles orientation/rotation similarly to the way the built-in Calc app does. If you check out that app, in portrait mode there's a normal calculator, and if you rotate to landscape mode there are additional buttons that appear to the left. I can't figure out how to do this by setting the autosize masks. The problem is the "normal" calculator view is 320px wide in portrait mode, but actually shrinks to around 240px in landscape mode to fit the additional controls. I've seen examples like the AlternateViews sample app that have two different view controllers (one for portrait and one for landscape), but they don't seem to animate the transitions between the views nicely like the Calc app does. I've also tried setting the frames for the views manually in willAnimateSecondHalfOfRotationFromInterfaceOrientation, but it doesn't seem to look "quite right" and also I'm not certain how that works with the autoresize mask. Any ideas how this is done? Thanks!

  • What method of UIView gets called when instantiated from a NIB?

    - by retailevolved
    I have a simple custom view that is connected via outlet to a NIB. For this particular view, there are actions that I would like to perform on the view when it is initialized, no matter what NIB it is on. Trouble is, neither the (id)init or the (id)initWithFrame:(CGRect)frame methods are getting called on the custom view. Which method gets called on a UIView when it is instantiated from a NIB? I would just use the view controller and viewDidLoad method except that this particular view appears on a lot of different NIBs.

  • Working with Content Shell on windows 7

    - by JAre
    I can't run Content Shell on my system (Windows 7 x64): When i run --dump-render-tree with the stable release content_shell.exe crashes with message: [XXXX:XXXX:0522/XXXXXX:XXXXXXXXX:FATAL:content_main_runner.cc(735)] Check failed: base::i18n::InitializeICU() were X - some number. And i can't run dev build because it misses mojo_system.dll. Is there any way to fix it? Does it work on Linux or MacOS? If so i probably can run it in VM For the time being.

  • malloc:mmap(size=XX) failed (error code=12)

    - by Michel
    I have a memory problem in an iPhone app, giving me a hard time. Here is the error message I get: malloc: * mmap(size=9281536) failed (error code=12) * error: can't allocate region I am using ARC for this app, in case that might be useful information. The code (below) is just using a file in the Bundle in order to load a core data entity. The strange thing is the crash happens only after more than 90 loops; while it seems to mee that since the size of the "contents" in getting smaller and smaller, the memory request should also get smaller and smaller. Here is the code, if any one can see a flaw please let me know. NSString *path,*contents,*lineBuffer; path=[[NSBundle mainBundle] pathForResource:@"myFileName" ofType:@"txt"]; contents=[NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil]; int counter=0; while (counter<10000) { lineBuffer=[contents substringToIndex:[contents rangeOfCharacterFromSet:[NSCharacterSet newlineCharacterSet]].location]; contents=[contents substringFromIndex:[lineBuffer length]+1]; newItem=[NSEntityDescription insertNewObjectForEntityForName:@"myEntityName" inManagedObjectContext:context]; [newItem setValue:lineBuffer forKey:@"name"]; request=[[NSFetchRequest alloc] init]; [request setEntity: [NSEntityDescription entityForName:@"myEntityName" inManagedObjectContext:context]]; error=nil; [context save:&error]; counter++; }

  • Passing a column name instead of index in sqlite3

    - by user271753
    The problem code: NSString *query = @"SELECT Name FROM Category"; sqlite3_stmt *statement; if (sqlite3_prepare_v2(database, [query UTF8String], -1, &statement, nil) == SQLITE_OK) { while (sqlite3_step(statement) == SQLITE_ROW) { char *row =(char *)sqlite3_column_text(statement,0); char *rowData = (char *)sqlite3_column_text(statement,1); NSString *fieldName = [[NSString alloc] initWithUTF8String:row]; NSString *fieldValue = [[NSString alloc] initWithUTF8String:rowData]; NSLog(@"%@",fieldName); NSLog(@"%@",fieldValue); [fieldName release]; [fieldValue release]; } sqlite3_finalize(statement); } char *row =(char *)sqlite3_column_text(statement,0); In the above code instead of 0 can't I just pass a column name? How can I do that ?

  • How to set clickable and highlightable a View?

    - by Pentium10
    I have ViewStubs in my layout. If I set clickable and implement the OnClickListener this does work only on the root of the element. But the layout holds parent elements, and when I click on those the click is not recognized. How do I make a full row/view of ViewStub as whole to be clickable and highlightable like a ListView elements? Also what do I have to add to get that orange highlight?

  • What's the correct way to represent a linear process in CocoaTouch (UIKit)?

    - by UloPe
    I need to represent a linear process (think wizard) in an iPad app. In principle I could use a UINavigationController and just keep pushing new controllers for each step of the process. But this seems rather inefficient since the process I'm modeling has no notion of navigating backwards so all previous views would pointlessly stay around and use up resources. At the moment I keep adding and removing a subview to one "master" viewcontroller and basically swapping out the contents. This works but feels rather clunky and I hope there is some nicer way to achieve this. Additionally there needs to be an animated transition between the views. (I have this working at the moment via beginAnimations / commitAnimations)

  • Which way to store this data is effective?

    - by Tattat
    I am writing a game, which need a map, and I want to store the map. The first thing I can think of, is using a 2D-array. But the problem is what data should I store in the 2D-array. The player can tap different place to have different reaction. So, I am thinking store a 2D-array with objects, when player click some position, and I find it in the array, and use the object in that array to execute a cmd. But I have a concern that storing lots of object may use lots of memory. So, I am think storing char/int only. But it seems that not enough for me. I want to store the data like that: { Type:1 Color:Green } No matter what color is, if they are all type 1, the have same reactions in logic, but the visual effect is based on the color. So, it is not easy to store using a prue char/int data, unless I make something like this: 1-5 --> all type 1. 1=color green , 2=color red, 3 = color yellow.... ... 6-10 --> all type 2. 2 = color green, 2 = color red ... ... So, do you have any ideas on how to minimize the ram use, but also easy for me to read... ...thx

  • UITableViewCell height with 0 rows

    - by Typeoneerror
    I've got a moderately uncustomized UITableView in my application that presents an array of up to 6 peers for a networking game. When no peers are found the numberOfRowsInSection is 0, so when it loads up, there's no rows in the table: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 0; } Trouble is, the height of each cell is not adjusted to match heightForRowAtIndexPath unless the numberOfRowsInSection is 0. I hard-coded in "1" for this and the height is adjusted. - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { return kTableRowHeight; } Can anyone tell me why this is? Will once the data that is being presented is longer than "0" length, will the height of the table cells jump to the correct height? I'd like them to be the correct height even if the row length is 0.
