  • Memory leak when returning object

    - by Yakattak
    I have this memory leak that has been very stubborn for the past week or so. I have a class method I use in a class called "ArchiveManager" that will unarchive a specific .dat file for me, and return an array with it's contents. Here is the method: +(NSMutableArray *)unarchiveCustomObject { NSMutableArray *array = [NSMutableArray arrayWithArray:[NSKeyedUnarchiver unarchiveObjectWithFile:/* Archive Path */]]; return array; } I understand I don't have ownership of it at this point, and I return it. CustomObject *myObject = [[ArchiveManager unarchiveCustomObject] objectAtIndex:0]; Then, later when I unarchive it in a view controller to be used (I don't even create an array of it, nor do I make a pointer to it, I just reference it to get something out of the array returned by unarchiveCustomIbject (objectAtIndex). This is where Instruments is calling a memory leak, yet I don't see how this can leak! Any ideas? Thanks in advance. Edit: CustomObject initWithCoder added: -(id)initWithCoder:(NSCoder *)aDecoder { if (self = [super init]) { self.string1 = [aDecoder decodeObjectForKey:kString1]; self.string2 = [aDecoder decodeObjectForKey:kString2]; self.string3 = [aDecoder decodeObjectForKey:kString3]; UIImage *picture = [[UIImage alloc] initWithData:[aDecoder decodeObjectForKey:kPicture]]; self.picture = picture; self.array = [aDecoder decodeObjectForKey:kArray]; [picture release]; } return self; }

  • Anyone knows of a good addressbook implementation?

    - by Tsahi Levent-Levi
    I am looking to add an address book to one of my programs. For that purpose, I want to have something that is flexible and customizable to the point of allowing me to hook up additional metadata to contacts in it from third parties. I don't mind paying for a solution as long as I get something that is usable for me. My requirements: Optimized to run on embedded devices Preferably in source code form Ability to add my own fields to contacts over those the address book provides out of the box Ability to plugin "stuff" to it to enhance it without changing its base code too much Has a C or C++ interface

  • Dismissing pickers and keyboards invoked by a UIWebView

    - by Dev Kanchen
    I am implementing an in-app browser using UIWebView, that shows an 'action' button up-top that - when tapped - scales the UIWebView and allows the user to perform some other actions. If, however, at the point of tapping this 'action' button, the user were entering some text on the webview, or using a picker to select an option from a drop-down list, then the webview gets scaled without dismissing the keyboard/picker. Apart from being ugly, this also obscures my main view and controls. So is there a way to make a UIWebView dismiss all associated input controls, such as keyboards/pickers, when asked to? I tried using [myWebView resignFirstResponder] but that didn't work. Any ideas? Thanks.

  • How to store UISegmentedControle state in NSUserdefaults

    - by Chrizzz
    The problem is when de selectedSegmentIndex is unselected: "UISegmentedControlNoSegment" alias "-1". The other states (0, 1, 2 , etc.), I can store as Integers and retrieve with carTypeSegmentedControl.selectedSegmentIndex = [defaults integerForKey:@"typeOfCar"]; But -1 is no NSInteger. I also tried to remove the Integer out of the NSUserdefaults but a request would return an "0", which is not acceptable. So, is there another easy way? tnx for reading

  • Unable to use NSURLConnection to get contents of password/username protected webpage

    - by bubster
    I am trying to get the contents of a webpage that requires a password and user name to access. I am using a NSURLConnection object to get it however when I write the NSMutableData object that is returned to a file all I get is the login page. Normally when you try to load the password protected page when you are not logged in it redirects to the login page however I thought that if I provided valid credentials then this I would be able to view the password protected page. Also I do not know if it is relevant the website is using a microsoft mysql database on an IIS (internet information server). Note: [protectionSpace authenticationMethod] returns NSURLAuthenticationMethodServerTrust I am pretty unfamiliar with this so any ideas would be greatly appreciated. Below is all of the relevant code: - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { // This method is called when the server has determined that it // has enough information to create the NSURLResponse. // It can be called multiple times, for example in the case of a // redirect, so each time we reset the data. // receivedData is an instance variable declared elsewhere. [receivedData setLength:0]; } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { // Append the new data to receivedData. // receivedData is an instance variable declared elsewhere. [receivedData appendData:data]; } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { // release the connection, and the data object //[connection release]; // receivedData is declared as a method instance elsewhere //[receivedData release]; // inform the user NSLog(@"Connection failed! Error - %@ %@", [error localizedDescription], [[error userInfo] objectForKey:NSURLErrorFailingURLStringErrorKey]); } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { // do something with the data // receivedData is declared as a method instance elsewhere NSLog(@"Succeeded! Received %d bytes of data",[receivedData length]); // release the connection, and the data object //[connection release]; //[receivedData release]; //Write data to a file [receivedData writeToFile:@"/Users/matsallen/Desktop/receivedData.html" atomically:YES]; } - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace: (NSURLProtectionSpace *)protectionSpace { NSLog(@"The connection encountered a protection space. The authentication method is %@", [protectionSpace authenticationMethod]); secureTrustReference = [protectionSpace serverTrust]; //SecTrustResultType *result; //OSStatus status = SecTrustEvaluate(secureTrustReference, result); //NSLog(@"Result of the trust evaluation is %@",status); return YES; } - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { NSURLCredential *newCredential; newCredential = [NSURLCredential credentialWithUser:@"username" password:@"password" persistence:NSURLCredentialPersistenceForSession]; newCredential = [NSURLCredential credentialForTrust:secureTrustReference]; // [[challenge sender] useCredential:newCredential forAuthenticationChallenge:challenge]; // [[challenge sender] continueWithoutCredentialForAuthenticationChallenge:challenge]; } #pragma mark - View lifecycle - (void)viewDidLoad { receivedData = [[NSMutableData alloc] init]; [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. // Create the request. NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.markallenonline.com/secure/maoCoaching.aspx"] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; // create the connection with the request // and start loading the data NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; if (theConnection) { // Create the NSMutableData to hold the received data. // receivedData is an instance variable declared elsewhere. receivedData = [NSMutableData data]; NSLog(@"Connection succeeded!"); } else { // Inform the user that the connection failed. NSLog(@"Connection failed!"); } }

  • "Don't Allow" in LocationManager keeps logging errors

    - by stephanie.moreau
    I have an app that checked for location. It asks the user to use location and if the user says no on the menu there is an issue when i load the mapview. Once i select the mapView it asks for the user location again. If the user says no again my console keeps displaying errors/warning as well as my NSLog from the "didFailWithError" of my location Manager class. Is there a way of stopping the LocationManage:didFailWithErrors if the user has already said no? I don't think Apple would accept my app if the Log file gets filled up my the LocationManager Here is an example of what gets repeated in the console ERROR,Time,290362745.002,Function,"void CLClientHandleDaemonDataRegistration(__CLClient*, const CLDaemonCommToClientRegistration*, const __CFDictionary*)",server did not accept client registration 1 WARNING,Time,290362745.005,Function,"void CLClientHandleDaemonInvalidation(__CFMessagePort*, void*)",client 1035.0 has been disconnected from daemon 2010-03-15 12:19:05.002 SAQ[1035:207] LocationManager Error Denied by user

  • Embedding Youtube Videos on user's wall with the Javascript API

    - by dragonmantank
    I'm attempting to embed a Youtube video on a user's wall using the Javascript API. I've poured over a bunch of different tutorials and came up with this: var data = { method: 'feed', link: current_video_url, // Link to the vide on our site source: current_video_src, // Link to the Youtube video, http://youtube.com/v/[hash] picture: current_picture_url, // Thumbnail from youtube title: current_video_title, // Title from our page caption: current_video_description // Text from our page } FB.ui(data); Running the Facebook Debugger shows that the current_video_url link is being properly parsed for OG tags and is available as an embedded video. I ran a debugger and all the variables are being properly set in the data variable. This worked fine for about 2 days, and then we pushed the site live. We set up a new AppID in Facebook but now all the videos are just thumbnails instead of being embedded in the user's wall. I thought maybe this is a problem with the live site but now the dev site is broken too. What's the best way to get this to work consistently?

  • iui transition moving in wrong direction

    - by Toddeman
    i am using iUI to build a native looking web app for iDevices. whenever i click a link with an href of #something that leads to another div on my page, the transition effect moves (correctly) as if the page were sliding in from the right like it does on any other iDevice app. a portion of my app requires an indefinite number of sub pages though, so i generate them on the fly, assign them and id, and set the window location to something like myip/mobile/#_newdiv. this causes the transition effect to move in the wrong direction though (as if the page were sliding in from the LEFT, opposite native iDevices). is there any way to fix this?

  • NSString: EOL and rangeOfString issues

    - by carloe
    Could someone please tell me if I am missing something here... I am trying to parse individual JSON objects out of a data stream. The data stream is buffered in a regular NSString, and the individual JSON objects are delineated by a EOL marker. if([dataBuffer rangeOfString:@"\n"].location != NSNotFound) { NSString *tmp = [dataBuffer stringByReplacingOccurrencesOfString:@"\n" withString:@"NEWLINE"]; NSLog(@"%@", tmp); } The code above outputs "...}NEWLINE{..." as expected. But if I change the @"\n" in the if-statement above to @"}\n", I get nothing.

  • how and where should I set and load NSUserDefaults in a utility app?
