  • Problem with Xcode and iPhone preference files

    - by CyDummy
    Hi, I created four language files for my app: two for the preferences and two for the strings. I added them into Xcode and it works great on the phone but the string files are shown as "Localizable.strings (de)" and "Localizable.strings (en)", while I have two files called "Root.plist" under the "Settings.bundle" in the groups "de.lproj" and "en.lproj" (see screenshot).When I don't add the two "Root.plist" files instead of "Settings.bundle", I get what I want ("Root.plist (de)" and "Root.plist (en)") but I have no "Settings.bundle" in Xcode. Is somebody out there who can help me to a get what I want?

  • Bug on submitted app binary but not in the simulator - CALayer position contains NaN

    - by Jonathan Thurft
    I submitted my app to the App Store where is ready to download. I've since then received some interesting crash reports when people select an image from the ImagePicker in one of my views. This bug (see below) makes the app crash. I was wondering 2 things. Can anyone spot the problem in the code below? How do you deal with bugs that are only in the App Binary but do not show up when trying to recreate them on the dev environment? - I can make the app crash with the Binary that is on the app store but when I do the same on the simulator or on my test phone the app works perfectly.. The Crash report in BugSense CALayer position contains NaN: [798 nan] Class: CALayerInvalidGeometry 0x00120e99 -[imageCroppingViewController imagePickerController:didFinishPickingMediaWithInfo:] (imageCroppingViewController.m:126) + 163481 The Code - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; imageView.image = image; CGRect rect; rect.size.width = image.size.width; rect.size.height = image.size.height; imageView.center = scrollView.center; [imageView setFrame:rect]; scrollView.contentSize = imageView.frame.size; self.navigationController.navigationBar.hidden = NO; [myPicker.view removeFromSuperview]; }

  • Can't use method from class in other file

    - by user1833848
    I am not able to use one of my methods that i implemented in my tableviewcell file in my tableview controller implementation. I tried searching the web and xcode help with no luck. My codes looks like this: TableViewController.h: #import TableViewCell.h @interface TableViewController : UITableViewController @property (nonatomic, strong) IBOutlet UIBarButtonItem *A1Buy; @property (nonatomic, getter = isUserInteractionEnabled) BOOL userInteractionEnabled; - (IBAction)A1Buy:(UIBarButtonItem *)sender; TableViewController.m: @implementation A1ViewController @synthesize A1Buy = _A1Buy; @synthesize userInteractionEnabled; - (IBAction)A1Buy:(UIBarButtonItem *)sender { [TableViewCell Enable]; //this is where it gives an error } TableViewCell.h: @interface TableViewCell : UITableViewCell { BOOL Enable; BOOL Disable; } @property (nonatomic, getter = isUserInteractionEnabled) BOOL userInteractionEnabled; TableViewCell.m: @implementation TableViewCell; @synthesize userInteractionEnabled; - (BOOL) Enable { return userInteractionEnabled = YES; } - (BOOL) Disable { return userInteractionEnabled = NO; } As you can see i am trying to enable user interaction with a button, but Xcode only gives me errors like "class does not have this method" and stuff like that. All files are importet correctly so thats not why. Would appreciate any help. Thanks!

  • Using iPhone Core Data to many Relationship

    - by BLeB
    When I define a to many relationship between entities in Xcode and then generate the data class from the entity I get a header with the following methods defined: @interface PriceList (CoreDataGeneratedAccessors) - (void)addItemsObject:(PriceListItem *)value; - (void)removeItemsObject:(PriceListItem *)value; - (void)addItems:(NSSet *)value; - (void)removeItems:(NSSet *)value; @end When I attempt to call addItemsObject with the following code a doesNotRecognizeSelector exception is thrown. PriceListItem *item = [NSEntityDescription insertNewObjectForEntityForName:@"PriceListItem" inManagedObjectContext:managedObjectContext]; item.cat = [attributeDict valueForKey:@"c"]; item.sel = [attributeDict valueForKey:@"s"]; [self addItemsObject:item]; From what I have read I do not have to implement these methods and that they are generated at runtime. Any ideas?

    I'm trying to integrate the MCPKit MySQL framework available at http://mysql-cocoa.sourceforge.net/ into my cocoa application. I've added the framework and included the header file but when I try to define my first MCPConnection variable it says "MCPConnection undeclared". Is anyone successfully using MCPKit on leopard ? Or is there another framework that people use to access MySQL ?

  • Passing a pointer to an array to glGenBuffers

    - by Josh Elsasser
    I'm currently passing an array to a function, then attempting to use glGenBuffers with the array that is passed to the function. I can't figure out a way to get glGenBuffers to work with the array that I've passed. I have a decent grasp of the basics of pointers, but this is beyond me. This is basically how the render code works. It's a bit more complex, (colours using the same array idea, also not working) but the basic idea is as follows: void drawFoo(const GLfloat *renderArray, GLuint verticeBuffer) { glBindBuffer(GL_ARRAY_BUFFER, verticeBuffer); glBufferData(GL_ARRAY_BUFFER, sizeof(verticeBuffer)*sizeof(GLfloat), verticeBuffer, GL_STATIC_DRAW); glVertexPointer(2, GL_FLOAT, 0, 0); glEnableClientState(GL_VERTEX_BUFFER); glDrawArrays(GL_TRIANGLE_FAN, 0, 45); glDisableClientState(GL_VERTEX_BUFFEr); } Thanks in advance for the help

  • Creation of model in core data on the fly

    - by user1740045
    How can we create a model in core data on the fly? I.e getting the schema of database from somewhere and then creating a Core Data Object graph? *QuesTion:* Yes thats fine, agreed with all the advantages. But, can anybody can tell practically, what is the benefit of integrating Core Data into project instead of using SQL directly. 1.No need to write SQL boiler plate code [but need to learn Core Data Model (steep curve)] 2.WE can undo and redo changes [but practically who needs it] 3.we can migrate to another schema [that can be done by SQLite as well jus need to add another field into table] 4.For say aggregation on some field in table,in Core Data we need to loop through Core Data Objects whereas in SQLite we need to first write SQLite Boiler Plate Code and then the basic aggregation SQL query,which is easy to write,only length of code will increase...But in case of Core Data (need to learn a lot). So apart from reducing the length of Code,does it actually adds value to project? or in terms of Memory Efficiency,Performance,etc.. PS: If anybody has actualy worked on Core Data(Model Creation On the Fly) , if possible share and gve pointers..thanks!

  • didSelectRowAtIndexPath being called after viewDidLoad of the called view

    - by Serguei Fedorov
    I am trying to pass variables over to the new view. I have the following code: appDelegate *dataCenter = (AppDelegate*)[[UIApplication sharedApplication] delegate]; dataCenter.myVariable = [array objectAtIndex:indexPath.row]; in the didSelectRowAtIndexPath of the calling view. However, the issue that I have is that this variable is empty in the vewDidLoad function of the next view, simply because it fired off BEFORE the didSelectRowAtIndexPath of the calling view. I am using storyboard to link the views together. Both are UITableView. If I hit back and then reselect the table element it is then set, granted that by the time I hit back and then selected again, the variable got set. Is there any way to for the order of execution? I really don't want to do UI view switching on the back end. Any help is greatly appreciated!

  • Button not moving on my interface

    - by user1500134
    First before I say anything I want to announce that i'm fairly new to this kind of stuff so don't get all super techie on me :D ! Ok so i'm making an app and i'm trying to get a button to move to certain coordinates depending on the screen size of the phone (4, 4S, 5, etc...). I have correct syntax but the button will not move at all. Here is the part of my .m ViewController file... - (void)viewDidLoad { if([[UIScreen mainScreen] respondsToSelector:NSSelectorFromString(@"scale")]) { if ([[UIScreen mainScreen] scale] < 1.1) { CGRect frame = done.frame; frame.origin.x = 129; //New x coordinate frame.origin.y = 401; //New y coordinate done.frame = frame; NSLog(@"Standard Resolution"); } if ([[UIScreen mainScreen] scale] > 1.9) { NSLog(@"High Defenition Resolution"); } } [super viewDidLoad]; // Do any additional setup after loading the view from its nib. } The NSLog is triggering int he console saying 'Standard Resolution'but the button doesn't move from where I placed it in the XIB file. This may be a small stupid mistake but hopefully you can help me anyways... Thanks guys! :) P.S. Yes I did link my IBOutlet to the button

  • 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!

  • Settings cell selected background view removes backgroundview

    - by Chris
    I'm trying to set up custom UITableViewCells. I can set the backgroundView no problem, but if I set selectedBackgroundView, the cell's background becomes white and only the selected background is seen: - (void) createCell: (UITableViewCell*)cell onRow: (NSUInteger)row { UIImageView* bgImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cell_background_red.png"]]; cell.backgroundView = bgImage; cell.selectedBackgroundView = bgImage; cell.textLabel.hidden = YES; UILabel* titleLabel = [[UILabel alloc] initWithFrame: CGRectMake(20, CGRectGetHeight(cell.frame) / 2, 200, 50)]; titleLabel.text = [[self.ruleList objectAtIndex: row] objectForKey: TitleKey]; titleLabel.backgroundColor = [UIColor clearColor]; [cell.contentView addSubview: titleLabel]; }

  • fastest in objC: IsEqualToString:@"" or length > 0?

    - by Cœur
    I'd like to know which one is fastest for testing a non-empty NSString for iOS 4.0+ (iPhone 3G). Note: the strings to test will be 99% of the time from 2 to 100 chars length. if ([foo length] > 0) or if ([foo isEqualToString:@""] == NO && foo != nil) I think it depends if isEqualToString: compares the length first (and in that case first way is faster) or if isEqualToString: compares first character of strings first (and in that case second way might be faster). ps: I already know isEqualToString: is faster than isEqual: which is itself faster than compare:.

  • passing info from facebook to UITabBarController

    - by EquinoX
    When my app first start, it shows up a main page showing to login to facebook and then it goes to the UITabBarController. The code that I have in my app delegate is the following: //this is the .h @interface NMeAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; MainViewController *controller; UITabBarController *tabBar; } @property (nonatomic, retain) IBOutlet UITabBarController *tabBar; @property (nonatomic, retain) MainViewController *controller; @property (nonatomic, retain) IBOutlet UIWindow *window; @end //this is the .m of the app delegate #import "NMeAppDelegate.h" @implementation NMeAppDelegate @synthesize window; @synthesize tabBar; @synthesize controller; #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. controller = [[MainViewController alloc] init]; [window addSubview:tabBar.view]; [window addSubview:controller.view]; [window makeKeyAndVisible]; return YES; } Inside of MainViewController, I actually have a Facebook * facebook object, which basically has all of the information that I need. Every information that I need for this apps is queried in the MainViewController. The problem is that after getting this info and now I am in the UITabViewController... how do I get those information that I already queried facebook for? I have a class called UserInfo as well, which basically has everything essential I need. I need to have the info from UserInfo so that the other ViewController in the UITabBarController have access to it.... I hope my question makes sense

  • Code formatting when using pointers

    - by HD-VRSCA
    Is there any reason why the asterisk is next to the object type in this code? I'm a little confused by the way I see this used. Some times it looks like this: NSString* stringBefore; and sometimes like this: NSString *stringBefore; Is there a difference? Or a right or wrong way to do this? Thanks
