  • Cocoa - NSFileManager removeItemAtPath Not Working

    - by Kevin
    Hey there everyone, I am trying to delete a file, but somehow nsfilemanager will not allow me to do so. I do use the file in one line of code, but once that action has been ran, I want the file deleted. I have logged the error code and message and I get error code: 4 and the message: "text.txt" could not be removed Is there a way to fix this error "cleanly" (without any hacks) so that apple will accept this app onto their Mac App Store? EDIT: This is what I am using: [[NSFileManager defaultManager] removeItemAtPath:filePath error:NULL]; Thanks, kevin

  • iOS bluetooth low energy not detecting peripherals

    - by user3712524
    My app won't detect peripherals. Im using light blue to simulate a bluetooth low energy peripheral and my app just won't sense it. I even installed light blue on two devices to make sure it was generating a peripheral signal properly and it is. Any suggestions? My labels are updating and the NSLog is showing that the scanning is starting.

  • Objective C Enumerate Sentences in a paragraph

    - by Faz Ya
    I would like to write an enumerator that would go through a paragraph of text and gives me one sentence at a time. I tried using stringEnumerate with the NSStringEnumerationBySentences but that simply looks at the periods and fails. For example, lets say I have the following text Block: "Senator John A. Boehner decided not to move forward. He also decided not to call the congress. The news reporter said though...." I would like my function to break down the above paragraph in the following sentences: Senator John A. Boehner decided not to move forward He also decided not to call the congress (No third sentence because it's a half a sentence) The String Enumerator with the sentence optionjust looks at the periods and breaks down that way which is wrong: Senator John A. Boehner decided not to move forward He also decided not to call the congress The news reporter said though.... Is there any library or function that I can call that does a better job at this? Thanks - (NSMutableString *) getOnlyFullSentencesFromTextBlock:(NSMutableString *) textBlock{ [textBlock enumerateSubstringsInRange:NSMakeRange(0, [textBlock length]) options:NSStringEnumerationBySentences | NSStringEnumerationLocalized usingBlock:^(NSString *substring, NSRange substringRange, NSRange enclosingRange, BOOL *stop) { NSLog(@"Sentence Frag:%@", substring); }]; return textBlock; }

  • Facebook writing on a wall problem - retrieves only null value.

    - by Viral
    hi all friends, I am making a game application in that I want to pass my score on wall of face book. I've completed all the things (the log in and message passing part) but when I passes the score via global variable, I am getting only null as a value and not the score that I want. Is there any way to pass data or string to Face book and write on a wall? My code is (void)viewDidLoad { static NSString* kApiKey = @"be60415be308e2b44c0ac1db83fe486b"; static NSString* kApiSecret = @"4f880c7e100321f808c41b1d3c813dfa"; _session = [[FBSession sessionForApplication:kApiKey secret:kApiSecret delegate:self] retain]; score = [NSString stringWithFormat:@"%@",appDelegate.myTextView]; [_session resume]; [super viewDidLoad]; } whre score is NSString and myTextView is NSString in other viewcontrollerfile, And appDelegate is global variable. Any help?? thanks in advance.

  • iPhone SDK:How do you play video inside a view? Rather than fullscreen.

    - by Jessica
    Hi, I am trying to play video inside a UIView, so my first step was to add a class for that view and start playing a movie in it using this code: - (IBAction)movie:(id)sender{ NSBundle *bundle = [NSBundle mainBundle]; NSString *moviePath = [bundle pathForResource:@"Movie" ofType:@"m4v"]; NSURL *movieURL = [[NSURL fileURLWithPath:moviePath] retain]; MPMoviePlayerController *theMovie = [[MPMoviePlayerController alloc] initWithContentURL:movieURL]; theMovie.scalingMode = MPMovieScalingModeAspectFill; [theMovie play]; } But this just crashes the app when using this method inside it's own class, but is fine elsewhere. Does anyone know how to play video inside a view? and avoid it being full screen?

  • What's a good way to create an Event Calendar

    - by iFloh
    Hi, I want to create an Event Calendar for my iPhone App. In a first instance the Event Calendar is supposed to list the Events and have a Details View with additional info. It is also supposed to contain an action to trasfer a specific event to the iPhone Calendar. First thoughts go towards using a UITableView where I make the event dates as sections. Since the Calendar is supposed to span many month I am unsure whether this really is the best way to go about it. Any suggestions? Do you probably know some sample code that I might use ? thanks in advance

  • I dont know how or where to add the correct encoding code to this iPhone code...

    - by BC
    Ok, I understand that using strings that have special characters is an encoding issue. However I am not sure how to adjust my code to allow these characters. Below is the code that works great for text that contains no special characters, but can you show me how and where to change the code to allow for the special characters to be used. Right now those characters crash the app. enter code here - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{ if (buttonIndex == 1) { //iTunes Audio Search NSString *stringURL = [NSString stringWithFormat:@"http://phobos.apple.com/WebObjects/MZSearch.woa/wa/search?WOURLEncoding=ISO8859_1&lang=1&output=lm&term=\"%@\"",currentSong.title]; stringURL = [stringURL stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]; NSURL *url = [NSURL URLWithString:stringURL]; [[UIApplication sharedApplication] openURL:url]; } } And this: -(IBAction)launchLyricsSearch:(id)sender{ WebViewController * webView = [[WebViewController alloc] initWithNibName:@"WebViewController" bundle:[NSBundle mainBundle]]; webView.webURL = [NSString stringWithFormat:@"http://www.google.com/m/search?hl=es&q=\"%@\"+letras",currentSong.title]; webView.webTitle = @"Letras"; [self.navigationController pushViewController:webView animated:YES]; } Please show me how and where to do this for these two bits of code.

  • iphone - Can't uninstall app on device

    - by wallou
    hey guys, I am testing my app on my jailbreaked iPhone and i noticed something strange. When i want to uninstall it on device i got no cross to delete the app. All the other apps (not mines) have the white circled cross. Whereas on the simulator i am able to delete my app. Is it because i run it on a jailbreak with a codesign workaround? Or maybe i am missing something in the app plist. Let me know if you have a clue. Wallou

  • How to handle duplicate symbol error from 3rd party libraries?

  • UIButtons creating a native-like keyboard behavior.

    - by camilo
    Greets. A somehow detailed explanation on my problem, and what I have already done, and what I cannot do. I want to create a behavior resembling the one in the iPhone's keyboard. Basically, I want a view to appear when the user taps a button and WHILE the user taps that button. This, I accomplished. When the user lets go of the button WHILE his finger is on that button's area, I want to trigger an action "doing stuff". This, I was also able to do. Since all the buttons are near (like in the keyboard) and I don't want the user to select other button than the one he pressed, I reduced the hit area for the button using the -(BOOL)pointInside:(CGPoint)point withEvent:(UIEvent )event function. When the user presses the button, not lifting its finger, and dragging outside the button area, I want another action to trigger. This is the first problem... This function only triggers when the user's finger is far from the buttons' area, and this time the pointInside function is not being my friend. How can I detect the user finger "left" the button area the moment it exits its bounds? This, in case you didn't realize... was problem 1. The second problem is related with the drag enter. Again, I need to limit the area like in the drag exit. But I suppose that when I solve one of these, the other is the same. The problem is that in order to have a behavior like in the keyboard, I may need to detect the user started the touch in another button, never lifted his finger, and changed to another button. I can detect drag enter and drag exit IN THIS ORDER while on the same button. I cannot detect drag enter when the user first touched anywhere else other than the button where I want to detect the drag enter event. Basically what I need is to detect touch on any button (and not anywhere else in the view), and while the user is changing buttons without lifting the finger, I want to detect the new button being touched. This gigantic paragraph was problem #2. Any help, as you might guess, is highly appreciated. Best Regards. Thanks a lot!

  • Git history cleanup doesn't seem to have an effect

    - by eaigner
    Hi, i ran the following 2 commands to clean up .pbxuser and .mode1v3 files from my git repository, but afterwards when i e.g. fire up gitx i can still see them in the history. git filter-branch --tree-filter "git rm -rf --cached --ignore-unmatch *.pbxuser" HEAD rm -rf .git/refs/original/ && git reflog expire --all && git gc --aggressive --prune What did i misunderstand here? The commands seem to do the job but why is gitx still viewing the diffs in its history? Regards, Erik

  • How to upload contents of a file to a UITextView?

    - by Mike Rychev
    Hello! I have about twenty UITextViews and corresponding .txt files. What I want is to make each UITextView take the contents of the corresponding file and display it. Moreover, the text is formatted and it contains some formulas (copy/pasted from Grapher). I've heard about displaying formatted text in UIWebView, but I haven't found a clear explanation anywhere. Thanks in advance!

  • addObjectsFromArray

    - by derek.lo
    I have a question about memory management when using the addObjectsFromArray method. Basically, I have 2 arrays defined in the appDelegate. I need these 2 arrays for the duration of my application's runtime. I therefore release them in my appDelegate's dealloc method. When I go to use these two arrays in a class, I want one array to store the values from the other, so that the other can have it's contents removed, but still stick around for use. Something like this: [appDelegate.arrayTwo addObjectsFromArray:appDelegate.arrayOne]; [appDelegate.arrayOne removeAllObjects]; I'm getting the compiler error: EXC_BAD_ACCESS because of a pointer issue? retaining issue? Any help would be greatly appreciated! Thanks

  • UIImage - should be loaded with [UIImage imageNamed:@""] or not ?

    - by sagar
    Hello ! every one. I am having number of images with in my application. ( images more than 50 - approximately & it can extend according to client's need ) Each image are very large round about - 1024 x 768 & 150 dpi Now, I have to add all this images in a scroll view & display it. Ok, My question is as follows. According to me there are two options of loading large images imageNamed:@"" load asynchronously when viewDidLoad Called. Which is more preferable ? imgModel.image=[UIImage imageNamed:[dMain valueForKey:@"imgVal"]]; or like this. NSURL *ur=[[NSURL alloc] initFileURLWithPath:[[NSBundle mainBundle] pathForResource:lblModelName.text ofType:@"png"] isDirectory:NO]; NSURLRequest *req=[NSURLRequest requestWithURL:ur cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:40]; [ur release]; NSURLConnection *con=[[NSURLConnection alloc] initWithRequest:req delegate:self]; if(con){ myWebData=[[NSMutableData data] retain]; } else { } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { [myWebData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [myWebData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { [connection release]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { NSLog(@"ImageView Ref From - %@",imgV); // my image view & set image imgV.image=[UIImage imageWithData:myWebData]; [connection release]; connection=nil; }

  • -(void)dealloc - How ? Objective - C

    - by sagar
    Please Note that - this is not similar than this question. OK. To understand my question, First of all please see both of these destructors. - (void)dealloc { [Marketdetails release]; Marketdetails=nil; [parsedarray release]; parsedarray=nil; [Marketid release]; Marketid=nil; [marketname release]; marketname=nil; [super dealloc]; } - (void)dealloc { [super dealloc]; [Marketdetails release]; Marketdetails=nil; [parsedarray release]; parsedarray=nil; [Marketid release]; Marketid=nil; [marketname release]; marketname=nil; } See, Both destructors have different code. In First Destructor first current class objects are released & then [super dealloc] is called. In second Desctructor first [super dealloc] is called. My question is as follows. Where should we write [super dealloc] ? first or last ? or it doesn't matter ?

  • Format number as I type Expand this post

    - by conorhiggins
    Hi I am working on an app at the moment that requires number input to be formatted as the textfield changes as well as perform a calculation. I have the text fields set up so that as the user types notifications are passed out and a calculation is performed. However what I need to do now is format the text to be in this style: €1,000,000 rather than 1000000. I have this working for the output of the calculation already but everytime I try to apply it to the input text the simulator seems to crash or at least freezes for a while. I'd imagine its a simple enough fix.

  • Setting UIActivityIndicatorView while view is prepared

    - by iFloh
    Hi, I have a UITabbBarController with a UITableView. Under certain circumstances the TabBarControllers dataset requires updating when a user arrives from another view, e.g. the initial load when the TabBarController is called the first time, or when the settings are changed. This dataset update takes about 2 seconds and I want to show an UIActivityIndicatorView. Trouble is that when I enter from another view I don't know which view to attach it to, since the loading of the tabbarController is carried out in the viewWillAppear method. Any clues how I can go about this?
