  • iOS App with OCMaps crashes when using the phone in chinese Language

    - by Pedro Morte Rolo
    I've been given the task of doing maintenance to a iOS application that uses OCMapView. I have just realized that when using the application in chinese language, it blows up when the selector doClustering is invoked on a OCMapView instance. This is for me a very puzzling behaviour, because I thought that regardless of the environment language, the OCMapView class should allways have the same methods. Am I wrong? Do you have any recomentations about how to find a solution to this problem? Thank you, Pedro

  • Iphone internet connection (Reachability)

    - by ludo
    Hi, I saw any post about Reachability but people doesn't really give the exact answer to the problem. In my application I use the Reachability code from apple and in my appDelegate I use this: -(BOOL)checkInternet { Reachability *reachability = [Reachability reachabilityWithHostName:@"www.google.com"]; NetworkStatus internetStatus = [reachability currentReachabilityStatus]; BOOL internet; if ((internetStatus != ReachableViaWiFi) && (internetStatus != ReachableViaWWAN)) { internet = NO; }else { internet = YES; } return internet; } So the problem is even if I have an internet connection, this code telling me that I don't have one. Does anyone know what to do to make this working? Thanks,

  • My app crashes after multiple rotates

    - by Ian Rae
    My app is crashing when I try and rotate it more than a couple of times. I first thought it was just the iPhone Simulator, so I loaded the app onto an iPod touch, and it crashed after fewer rotates in a row. I suspect it's a memory leak in one of my rotate methods. The only place I can think that the crash is being caused is in willRotateToInterfaceOrientation:duration:. The only two methods related to rotate that I've added/extended are shouldAutorotateToInterfaceOrientation: and willRotateToInterfaceOrientation:duration and I don't think it's the first because it only contains the two words: return YES;. Here is my willRotateToInterfaceOrientation:duration: method so you can review it and see where the possible memory leak is. -(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)orientation duration:(NSTimeInterval)duration { UIFont *theFont; if ((orientation == UIInterfaceOrientationLandscapeLeft) || (orientation == UIInterfaceOrientationLandscapeRight)) { theFont = [yearByYear.font fontWithSize:16.0]; yearByYear.font = theFont; [theview setContentSize:CGSizeMake(460.0f, 635.0f)]; } else { theFont = [yearByYear.font fontWithSize:10.0]; yearByYear.font = theFont; [theview setContentSize:CGSizeMake(300.0f, 460.0f)]; } [theFont release]; } yearByYear is a UITextView theview is a UIScrollView if anyone has any idea of why my app is crashing, I would be greatly appreciative.

  • Access custom label property at didSelectRowAtIndexPath.

    - by Mr. McPepperNuts
    I have a UILabel for each cell at cellForRowAtIndexPath. UILabel *cellLabel = [[UILabel alloc] initWithFrame:frame]; cellLabel.text = myString; I want to access that string "myString" at didSelectRowAtIndexPath using indexpath. NSString *anotherString = cell.textLabel.text; returns null. Now if at cellForRowAtIndexPath, I did something like cell.textLabel.text = theString; then the didSelectRowAtIndexPath returns the appropriate cell. My question is, how can I access the text in the UILabel I apply to the cell, at didSelectRowAtIndexPath? Also, logging the cell in didSelectRowAtIndexPath returns cell: <UITableViewCell: 0x5dcb9d0; frame = (0 44; 320 44); autoresize = W; layer = <CALayer: 0x5dbe670>> Edit: NSString *myString = [[results objectAtIndex:indexPath.row] valueForKey:@"name"]; //cell.textLabel.text = myString; CGFloat width = [UIScreen mainScreen].bounds.size.width - 50; CGFloat height = 20; CGRect frame = CGRectMake(10.0f, 10.0f, width, height); UILabel *cellLabel = [[UILabel alloc] initWithFrame:frame]; cellLabel.text = myString; cellLabel.textColor = [UIColor blackColor]; cellLabel.backgroundColor = [UIColor whiteColor]; cellLabel.textAlignment = UITextAlignmentLeft; cellLabel.font = [UIFont systemFontOfSize:14.0f]; [cell.contentView addSubview:cellLabel]; [cellLabel release]; return cell;

  • UITableView Header Selection

    - by Reonarudo
    Hello, Can anyone explain me how can I detect a selection in a table view Header view like in tableView:didSelectRowAtIndexPath: ? It would be very useful for me. I've defined the header as UITableCellView so I could attach a UISwitch as an accessory view, and it worked great but now I can't detect the changes made in the switch. Any suggestions?

  • Saving a "project"-type document (containing sub-documents)

    - by andyvn22
    I'm trying to create a "project"-like document, in that it contains subdocuments in a specified directory. I'd like a brand new save of a document to set up that directory with appropriate subdirectories. I'd like a "Save As" to copy all those subdirectories and any files within them to the new location. But I'd like a "Save" to only update certain data files and (of course) not overwrite all the subdocuments! What's the "safe" way to do this? I tried keeping track of the file's location in my document, and checking to see if it was the same or different than the save location, but it feels messy, and I'm worried that Apple is doing something behind the scenes that will make this direct URL-to-URL comparison fail in some circumstances. Is there a standard way to do something like this?

  • Trying to recognize _NSFaultingMutableSet as member of NSSet

    - by Will
    I'm trying to recognize the result of a generic query to a managed object as an NSSet. Currently the class returned is a member of _NSFaultingMutableSet, which is clearly related, but fails the isMemberOf:[NSSet class] and isKindOf:[NSSet class] calls. Given that Cocoa doesn't do a direct implementation of NSSet, it's not surprising that I've got some air in the pipes, but I'm wondering if I'm messing something obvious up or this requires a higher grade of kung-fu than I possess. Code follows: SEL selector = NSSelectorFromString(someString); if(![self respondsToSelector:selector]){ NSLog(@"Error processing item"); return; } id items = [self performSelector:selector]; Class itemsClass = [items class]; if ( [itemsClass isKindOfClass:[NSSet class]]) { // do something }

  • How to select one NSCell in an NSTableView?

    - by Paperflyer
    I have a small NSTableView with a checkbox. Whenever the checkbox is not checked, I want one of the adjacent NSCells to be grayed out and inaccessible. However, I can't figure out how to address only one specific cell. -dataCellForRow of NSTableColumn always changes the template cell for the whole table column. How can I access one single cell?

  • How would one use Cocos2d to create a game like this.

    - by John Stewart
    http://itunes.apple.com/us/app/angry-birds/id343200656?mt=8&ign-mpt=uo%3D6 So I am getting started with this all game dev thing on iphone and I decided that I will start playing with Cocos2d as my starting engine. Now just so i have a goal in mind, I picked angry birds as my initial target of what sort of game play would I like to learn to build. This is not going to be a market release game. This is totally going to be learning purposes only. So to start off my question is: Would something like this be achievable using Cocos2d? How would I go about building the physics for this? How can one do a screen scroll like the way they do in cocos2d? (any example code would be great) This is just to start off. If you have any particular questions please do add to this question.

  • iphone memory leaks and malloc?

    - by Brodie4598
    Okay so im finally to the point where I am testing my iPad App on an actual iPad... One thing that my app does is display a large (2mb) image in a scroll view. This is causing the iPad to get memory warnings. I run the app in the instruments to check for the leak. When I load the image, a leak is detected and i see the following in the allocations: ALl Allocations: 83.9 MB Malloc 48.55 MB: 48.55 MB Malloc 34.63 MB: 34.63 MB What im trying to understand is how to plug the leak obviously, but also why a 2MB image is causing a malloc of 20x that size I am very new to programming in obj-c so im sure this is an obvious thing, but I just cant figure it out. Here is the code:

  • UIPickerView issues - iphone

    - by Rob J
    I have the following: - (NSInteger) numberOfComponentsInPickerView:(UIPickerView *)pickerView { return 2; } - (NSInteger) pickerView:(UIPickerView *) pickerView numberOfRowsInComponent:(NSInteger) component { return [genderPickerData count]; return [agePickerData count]; } When I do this, the UIPicker is split into 2 components, but the PickerData is only being represented for gender on both pickers. I am trying to figure out through Apple's confusing documentation on how I reference each individual component but can't seem to figure it out.

  • Playing wav files with AudioServices in iPhone

    - by Biranchi
    Hi All, I am trying to play two .wav files in my appllication, but i am only able to play the first wav file , the second file is not at all playing. I have added the AudioToolbox framework. In my .h file i have included the Audiotoolbox.h file and has the following declarations //Beep Sound SystemSoundID soundFileObject; SystemSoundID recycleFileObject; In my .m file i am registering both the wav files as following CFURLRef soundFileURLRef = CFBundleCopyResourceURL (CFBundleGetMainBundle (),CFSTR ("Beep"),CFSTR ("wav"),NULL ); AudioServicesCreateSystemSoundID (soundFileURLRef,&soundFileObject ); CFURLRef soundFileURLRef2 = CFBundleCopyResourceURL (CFBundleGetMainBundle (),CFSTR ("Recycle"),CFSTR ("wav"),NULL ); AudioServicesCreateSystemSoundID (soundFileURLRef2,&recycleFileObject ); And i have written two methods for playing each file individually. -(void)playBeepSound { NSLog(@"Beep sound called : %d", soundFileObject); AudioServicesPlaySystemSound (soundFileObject); } -(void)playRecycleSound { NSLog(@"Recycle sound called : %d", recycleFileObject); AudioServicesPlaySystemSound (recycleFileObject); } But i am only able to play the Beep sound , but not the second sound wav file. What is the error ??? Thanks

  • Toubleshooting mapkit performance

    - by brettr
    I'm plotting over 500 points on a map using mapkit. Zooming is a little jittery compared to the native google map app. I've discovered what is causing the slowness. I'm adding custom annotations so that I can later add different pin colors and buttons for detail views: - (MKAnnotationView *) mapView:(MKMapView *)mapView viewForAnnotation:(AddressNote *) annotation { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"currentlocation"]; annView.pinColor = MKPinAnnotationColorGreen; annView.animatesDrop=TRUE; annView.canShowCallout = YES; annView.calloutOffset = CGPointMake(-5, 5); return annView; } If I comment out the above code, everything works fine. Very smooth with zooming in/out. Should I be adding annotations differently to boost performance?

  • Why is my UIImageView blurred?

    - by Denis M
    I have a really weird problem with UIImageView. I have an image (an RGB png) 45x45 pixels which I add to the view. I can see that image is blurred after added to the view. Here is the same image in the simulator (left) and in Xcode (right): I have custom UIImageView class with this initWithImage code: - (id) initWithImage:(UIImage*) image { self = [super initWithImage:image]; self.frame = CGRectMake(0, 0, 45, 45); self.contentMode = UIViewContentModeScaleAspectFit; self.quantity = 1; if (self) { self.label = [[UITextField alloc]initWithFrame:CGRectMake(0,40,45,25)]; self.label.font = [UIFont systemFontOfSize:16]; self.label.borderStyle = UITextBorderStyleNone; self.label.enabled = TRUE; self.label.userInteractionEnabled = TRUE; self.label.delegate = self; self.label.keyboardType = UIKeyboardTypeNumbersAndPunctuation; self.label.textAlignment = UITextAlignmentCenter; } self.userInteractionEnabled = TRUE; // Prepare 3 buttons: count up, count down, and delete self.deleteButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; self.deleteButton.hidden = NO; self.deleteButton.userInteractionEnabled = YES; self.deleteButton.titleLabel.font = [UIFont systemFontOfSize:20]; self.deleteButton.titleLabel.textColor = [UIColor redColor]; [self.deleteButton setTitle:@"X" forState:UIControlStateNormal]; [self.deleteButton addTarget:self action:@selector(deleteIcon:) forControlEvents:UIControlEventTouchUpInside]; self.upCountButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; self.upCountButton.hidden = NO; self.upCountButton.userInteractionEnabled = YES; [self.upCountButton setTitle:@"+" forState:UIControlStateNormal]; [self.upCountButton addTarget:self action:@selector(addQuantity:) forControlEvents:UIControlEventTouchUpInside]; self.downCountButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; self.downCountButton.hidden = YES; self.downCountButton.userInteractionEnabled = YES; [self.downCountButton setTitle:@"-" forState:UIControlStateNormal]; [self.downCountButton addTarget:self action:@selector(removeQuantity:) forControlEvents:UIControlEventTouchUpInside]; return self; } I create it like this: UIImage *desertIcon = [UIImage imageNamed:@"desert.png"]; IconObj *desertIconView = [[IconObj alloc] initWithImage:desertIcon]; desertIconView.center = CGPointMake(265,VERTICAL_POINT_ICON); desertIconView.type = [IconObj TYPE_DESERT]; [self.view addSubview:desertIconView]; [desertIconView release]; Why would the displayed image be so than the one stored in a file?

  • NSInvocationOperation and main thread

    - by kpower
    Imagine that I have a view with some UIKit object as its subview (for example, UIActivityIndicatorView - this doesn't matter). This view also has a selector, called doSomething, which somehow manages UIKit object (in our example it can start or stop indicator view). I create NSInvocationOperation (from view's code parts) with initWithTarget:self selector:@selector(doSomething) object:nil. Then add it to NSOperationQueue. And all works fine. How?! It should be a new thread and non-thread-safe UIKit object! Why no error found (and no crash happened)?

  • Adding a custom subview (created in a xib) to a view controller's view - What am I doing wrong

    - by Fran
    I've created a view in a xib (with an activity indicator, a progress view and a label). Then I've created .h/.m files: #import <UIKit/UIKit.h> @interface MyCustomView : UIView { IBOutlet UIActivityIndicatorView *actIndicator; IBOutlet UIProgressView *progressBar; IBOutlet UILabel *statusMsg; } @end #import "MyCustomView.h" @implementation MyCustomView - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { // Initialization code } return self; } - (void)dealloc { [super dealloc]; } @end In IB, I set the file's owner and view identity to MyCustomView and connect the IBOutlet to the File's owner In MyViewController.m, I've: - (void)viewDidLoad { [super viewDidLoad]; UIView *subView = [[MyCustomView alloc] initWithFrame:myTableView.frame]; [subView setBackgroundColor:[UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.5]]; [myTableView addSubview:subView]; [subView release]; } When I run the app, the view is added, but I can't see the label, the progress bar and the activity indicator. What am I doing wrong?
