  • Is there an easy way to merge Localizable.strings files?

    - by mystify
    Problem: Using genstrings to create Localizable.strings files from a project. A few weeks later, some things changed and I run genstrings again. 75% of the new file is already in the old file. How could I merge the new file with the old file, so that the old file contains all of those 25% new key-value-pairs?

  • NSString stringWithContentsOfFile failing with what seems to be the wrong error code

    - by deanWombourne
    Hello. I'm trying to load a file into a string. Here is the code I'm using: NSError *error = nil; NSString *fullPath = [[NSBundle mainBundle] pathForResource:filename ofType:@"html"]; NSString *text = [NSString stringWithContentsOfFile:fullPath encoding:NSUTF8StringEncoding error:&error]; When passed in @"about" as the filename, it works absolutely fine, showing the code works. When passed in @"eula" as the filename, it fails with 'Cocoa error 258', which translates to NSFileReadInvalidFileNameError. However, if I swap the contents of the files over but keep the names the same, the other file fails proving there is nothing wrong with the filename, it's something to do with the content. The about file is fairly simple HTML but the eula file is a massive mess exported from Word by the legal department. Does anyone know of anything inside a HTML file that could cause this error to be raised? Much thanks, Sam

  • Initialization problem

    - by zp26
    I have a problem. This is my code. When i try to use the IBAction SavePosition the "arrayPosition" isn't update. Else if i initialize the "arrayPosition" in "SavePosition" the value is stored in the array. Why this anomaly? #import <UIKit/UIKit.h> @interface AccelerometroViewController : UIViewController <UIAccelerometerDelegate, UITextFieldDelegate, UIAlertViewDelegate>{ //..... NSMutableArray *arrayPosizioni; NSMutableArray *arrayPosizioniCorrenti; NSString *nomePosizioneCorrente; } -(IBAction)salvaPosizione; //... @property (nonatomic, assign) NSMutableArray *arrayPosizioni; @property (nonatomic, assign) NSMutableArray *arrayPosizioniCorrenti; @property (nonatomic, assign) NSString *nomePosizioneCorrente; @end #import "AccelerometroViewController.h" #import "Position.h" @implementation AccelerometroViewController float actualX; float actualY; float actualZ; @synthesize arrayPosition; @synthesize arrayCurrentPosition; @synthesize nameCurrentPosition; -(id)init { self = [super init]; if (self != nil) { arrayPosition = [[NSMutableArray alloc]init]; arrayCurrentPosition = [[NSMutableArray alloc]init]; nameCurrentPosition = [NSString stringWithFormat:@"noPosition"]; actualX = 0; actualY = 0; actualZ = 0; } return self; } -(void)updateTextView:(NSString*)nomePosizione { NSString *string = [NSString stringWithFormat:@"%@", nameCurrentPosition]; textEvent.text = [textEvent.text stringByAppendingString:@"\n"]; textEvent.text = [textEvent.text stringByAppendingString:string]; } -(IBAction)savePosition{ Posizione *newPosition; newPosition = [[Position alloc]init]; if([newPosition setValue:(NSString*)fieldNomePosizione.text:(float)actualX:(float)actualY:(float)actualZ]){ //setValue is a method of Position. I'm sure that this method is correct UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Salvataggio Posizione" message:@"Posizione salvata con successo" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:nil]; [alert show]; [alert release]; [arrayPosition addObject:newPosition]; } else{ UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Salvataggio osizione" message:@"Errore nel salvataggio" delegate:self cancelButtonTitle:@"Cancel" otherButtonTitles:nil]; [alert show]; [alert release]; } }

  • Animated status bar style transition, a la iPod app

    - by Ben Williamson
    In the iPod app, the navigation views have the default status bar style, and the Now Playing view is in the black style. The transition between them is animated with a crossfade. I want to do that. My first attempt: [UIView beginAnimations:@"whatever" context:nil]; [UIView setAnimationDuration:0.5]; self.navigationController.navigationBar.barStyle = UIBarStyleBlack; [UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleBlack [UIView commitAnimations]; No joy, it pops to black. Takers?

  • Received memory warning on setimage

    - by Sam Budda
    This problem has completely stumped me. This is for iOS 5.0 with Xcode 4.2 What's going on is that in my app I let user select images from their photo album and I save those images to apps document directory. Pretty straight forward. What I do then is that in one of the viewController.m files I create multiple UIImageViews and I then set the image for the image view from one of the picture that user selected from apps dir. The problem is that after a certain number of UIImage sets I receive a "Received memory warning". It usually happens when there are 10 pictures. If lets say user selected 11 pictures then the app crashes with Error (GBC). NOTE: each of these images are at least 2.5 MB a piece. After hours of testing I finally narrowed down the problem to this line of code [button1AImgVw setImage:image]; If I comment out that code. All compiles fine and no memory errors happen. But if I don't comment out that code I receive memory errors and eventually a crash. Also note it does process the whole CreateViews IBAction but still crashes at the end. I cannot do release or dealloc since I am running this on iOS 5.0 with Xcode 4.2 Here is the code that I used. Can anyone tell me what did I do wrong? - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. [self CreateViews]; } -(IBAction) CreateViews { paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask ,YES); documentsPath = [paths objectAtIndex:0]; //here 15 is for testing purposes for (int i = 0; i < 15; i++) { //Lets not get bogged down here. The problem is not here UIImageView *button1AImgVw = [[UIImageView alloc] initWithFrame:CGRectMake(10*i, 10, 10, 10)]; [self.view addSubview:button1AImgVw]; NSMutableString *picStr1a = [[NSMutableString alloc] init]; NSString *dataFile1a = [[NSString alloc] init]; picStr1a = [NSMutableString stringWithFormat:@"%d.jpg", i]; dataFile1a = [documentsPath stringByAppendingPathComponent:picStr1a]; NSData *potraitImgData1a =[[NSData alloc] initWithContentsOfFile:dataFile1a]; UIImage *image = [[UIImage alloc] initWithData:potraitImgData1a]; // This is causing my app to crash if I load more than 10 images! //[button1AImgVw setImage:image]; } NSLog(@"It went to END!"); } //Error I get when 10 images are selected. App does launch and work 2012-10-07 17:12:51.483 ABC-APP[7548:707] It went to END! 2012-10-07 17:12:51.483 ABC-APP [7531:707] Received memory warning. //App crashes with this error when there are 11 images 2012-10-07 17:30:26.339 ABC-APP[7548:707] It went to END!

  • Object leak using "retain"

    - by Abhinav
    I have a property defined with retain attribute which I am synthesizing: @property (nonatomic, retain) UISwitch *mySwitch; And inside my loadView I am doing this: self.mySwitch = [[UISwitch alloc] initWithFrame:CGRectMake(0, 0, 40, 20)]; And finally inside my dealloc I am doing this: self.mySwitch = nil; Am I leaking this object (mySwitch) as I have used one alloc? Should I autorelease it while assigning it frame? Please suggest.

  • Cocoa - does CGDataProviderCopyData() actually copy the bytes? Or just the pointer?

    - by jtrim
    I'm running that method in quick succession as fast as I can, and the faster the better, so obviously if CGDataProviderCopyData() is actually copying the data byte-for-byte, then I think there must be a faster way to directly access that data...it's just bytes in memory. Anyone know for sure if CGDataProviderCopyData() actually copies the data? Or does it just create a new pointer to the existing data?

  • Problems with creating and using of delegate-protocols

    - by Flocked
    Hello, I have the problem that I have created a delegate protocol, but the necessary methods are not executed, although I have implemented the protocol in my header file. Here are the detailed explanation: I created an instance of my ViewController (TimeLineViewController), which will be displayed. This ViewController contains a UITableView, which in turn receives the individual Cells / Rows from one instance of my TableViewCell. So the ViewController creates an instance of TableCellView. The TableViewCell contains a UITextView, which contains web links. Now I want, that not safari opens the links, but my own built-in browser. Unfortunately TableViewCell can not open a new ViewController with a WebView, so I decided to create a delegate protocol. The whole thing looks like this: WebViewTableCellDelegate.h: @protocol WebViewTableCellDelegate -(void)loadWeb; @end Then I created a instance WebViewDelegate in the TableViewCell: id <WebViewTableCellDelegate> _delegate; In the .m of the TableViewCell: @interface UITextView (Override) @end @class WebView, WebFrame; @protocol WebPolicyDecisionListener; @implementation UITextView (Override) - (void)webView:(WebView *)webView decidePolicyForNavigationAction:(NSDictionary *)actionInformation request:(NSURLRequest *)request frame:(WebFrame *)frame decisionListener:(id < WebPolicyDecisionListener >)listener { NSLog(@"request: %@", request); [_delegate loadWeb]; } @end - (void)setDelegate:(id <WebViewTableCellDelegate>)delegate{ _delegate = delegate;} And in my TimeLineViewController I implemented the protocol with < and the loadWeb-metode: - (void)loadWeb{ WebViewController *web = [[WebViewController alloc] initWithNibName:nil bundle:nil]; web.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController: web animated:YES]; [web release]; } And when the instance of the TableViewCell will be created in the TimelineViewController: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"MyIdentifier"; MyIdentifier = @"tableCell"; TableViewCell *cell = (TableViewCell *)[tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if(cell == nil) { [[NSBundle mainBundle] loadNibNamed:@"TableViewCell" owner:self options:nil]; cell = tableCell;} [cell setDelegate:self]; //… } It is the first time I created a own delegate-protocol, so maybe there are stupid mistakes. Also I´m learnung Objective-C and programming generally only for 4 weeks. Thanks for your help! EDIT: I think i found the problem, but I dont know how to resolve it. I try to use [_delegate loadWeb]; in the subclass of the UITextView (because that is the only way i can react on the weblinks) and the subclass can´t use [_delegate loadWeb];. I tried this in a other methode and it worked.

  • Mobile Safari Youtube opened via javascript

    - by Squeegy
    We have a youtube player embedded in a plage in Mobile Safari and it works great. But we need to be able to launch the youtube player by a means other than user tapping the video itself, for various reasons. So I am trying to figure out what event to trigger in javascript to make it happen with no luck. None of the following appear to work. var vid = document.getElementById('vid'); vid.click(); vid.onclick(); vid.ontouchend(); vid.ontouchstart(); vid.focus(); I tried to find an event handler added to the embedded object with this snippet, but didn't find anything. for (var key in vid) { if (typeof vid[key] == 'function') console.log(key +': '+ vid[key]); } Is this just so wrapped up in a custom plugin there is no way?

  • How to add an extra plist property using CMake?

    - by Jesse Beder
    I'm trying to add the item <key>UIStatusBarHidden</key><true/> to my plist that's auto-generated by CMake. For certain keys, it appears there are pre-defined ways to add an item; for example: set(MACOSX_BUNDLE_ICON_FILE ${ICON}) But I can't find a way to add an arbitrary property. I tried using the MACOSX_BUNDLE_INFO_PLIST target property as follows: I'd like the resulting plist to be identical to the old one, except with the new property I want, so I just copied the auto-generated plist and set that as my template. But the plist uses some Xcode variables, which also look like ${foo}, and CMake grumbles about this: Syntax error in cmake code when parsing string <string>com.bedaire.${PRODUCT_NAME:identifier}</string> syntax error, unexpected cal_SYMBOL, expecting } (47) Policy CMP0010 is not set: Bad variable reference syntax is an error. Run "cmake --help-policy CMP0010" for policy details. Use the cmake_policy command to set the policy and suppress this warning. This warning is for project developers. Use -Wno-dev to suppress it. In any case, I'm not even sure that this is the right thing to do. I can't find a good example or any good documentation about this. Ideally, I'd just let CMake generate everything as before, and just add a single extra line. What can I do?

  • How does a custom accessor method implementation in Core Data look like?

    - by dontWatchMyProfile
    The documentation is pretty confusing on this one: The implementation of accessor methods you write for subclasses of NSManagedObject is typically different from those you write for other classes. If you do not provide custom instance variables, you retrieve property values from and save values into the internal store using primitive accessor methods. You must ensure that you invoke the relevant access and change notification methods (willAccessValueForKey:, didAccessValueForKey:, willChangeValueForKey:, didChangeValueForKey:, willChangeValueForKey:withSetMutation:usingObjects:, and didChangeValueForKey:withSetMutation:usingObjects:). NSManagedObject disables automatic key-value observing (KVO, see Key-Value Observing Programming Guide) change notifications, and the primitive accessor methods do not invoke the access and change notification methods. In accessor methods for properties that are not defined in the entity model, you can either enable automatic change notifications or invoke the appropriate change notification methods. Are there any examples that show how these look like?

  • Corrupted image if variable is not static

    - by Jaka Jancar
    I'm doing the following: static GLfloat vertices[3][3] = { {0.0, 1.0, 0.0}, {1.0, 0.0, 0.0}, {-1.0, 0.0, 0.0} }; glColor4ub(255, 0, 0, 255); glEnableClientState(GL_VERTEX_ARRAY); glVertexPointer(3, GL_FLOAT, 0, vertices); glDrawArrays(GL_TRIANGLES, 0, 9); glDisableClientState(GL_VERTEX_ARRAY); This works ok: However, if I remove static from vertices and therefore re-create the data on the stack on each rendering, I get the following: This happens both on the simulator and on the device. Should I be keeping the variables around after I call glDrawArrays?

  • How to increment a value using a C-Preprocessor in Objective-C?

    - by mystify
    Example: I try to do this: static NSInteger stepNum = 1; #define METHODNAME(i) -(void)step##i #define STEP METHODNAME(stepNum++) @implementation Test STEP { // do stuff... [self nextFrame:@selector(step2) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step3) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step4) afterDelay:1]; } // ... When building, Xcode complains that it can't increment stepNum. This seems logical to me, because at this time the code is not "alive" and this pre-processing substitution stuff happens before actually compiling the source code. Is there another way I could have an variable be incremented on every usage of STEP macro, the easy way?

  • Get String Instead of Source - Xcode Cocoa

    - by Kevin
    Hello everyone, I have a program that will scan the contents of a website, and display it in a textbox. The problem is that it shows the html source. For example if my html code was: <html> <body> <p>Hello</p> </body> </html> instead of just showing hello, it'll show the code above... How can I get my objective c program to just read the hello, and not the html source.. I was assuming that it was the encoding when reading the website, but I might be possibly wrong.. I would greatly appreciate it if someone could give me a reasonable answer.. Best Regards, Kevin
