  • Profile Image Update Twitter API

    - by jshollax
    I am trying to upload a profile image to twitter using their API. I found some good examples on the web on how to format the URLRequest, however I just can't seem to get this to work. Any help would be appreciated. The URL that I am using from Twitter API is http://twitter.com/account/update_profile_image.json -(void)uploadImageForAccount:(NSURL *)theURL intUserName:(NSString *)_userName initPassWord:(NSString *)_passWord image:(NSData *)image{ userName = [_userName retain]; passWord = [_passWord retain]; UIApplication *app = [UIApplication sharedApplication]; app.networkActivityIndicatorVisible = YES; requestedData = [[NSMutableData alloc] initWithLength:0]; NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:theURL cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60]; [theRequest setHTTPMethod:@"POST"]; NSString *stringBoundary = [NSString stringWithString:@"0xKhTmLbOuNdArY"]; NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", stringBoundary]; [theRequest addValue:contentType forHTTPHeaderField:@"Content-Type"]; // Credentials NSString *creds = [NSString stringWithFormat:@"%@:%@", userName, passWord]; [theRequest addValue:[NSString stringWithFormat:@"Basic %@",[self base64encode:creds]] forHTTPHeaderField:@"Authorization"]; NSMutableData *postBody = [NSMutableData data]; [postBody appendData:[[NSString stringWithFormat:@"\r\n\r\n--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"source\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithString:@"canary"] dataUsingEncoding:NSUTF8StringEncoding]]; NSString *mimeType = mimeType = @"image/jpeg"; [postBody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"media\"; filename=\"%@\"\r\n", @"TNImage.jpeg"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithFormat:@"Content-Type: %@\r\n", mimeType] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:[[NSString stringWithString:@"Content-Transfer-Encoding: binary\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [postBody appendData:image]; [postBody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]]; [theRequest setHTTPBody:postBody]; NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self startImmediately:YES]; if(DEBUG) NSLog(@"Connection = %@",[connection description]); if (connection == nil) { if(DEBUG) NSLog(@"Connection was Nil"); } }

  • commitAnimations is not resizing my UIImageView subview

    - by AaronG
    I have created a UIView as a subview and to that subview I have added a UIImageView as a subview. UIView *viewCreated; UIButton *buttonCreated; UIImageView *imageViewCreated; CGRect myFrame = CGRectMake(0, 0, 1024, 1024); viewCreated = [[UIView alloc] initWithFrame:myFrame]; [viewCreated setTag:intTag]; viewCreated.backgroundColor = [UIColor redColor]; [self.view addSubview:viewCreated]; [self randomize]; UIImage *d1Image = [UIImage imageNamed:[NSString stringWithFormat:@"image%d.png", randomNumber]]; imageViewCreated = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f,0.0f,1024.0f, 1024.0f)]; [imageViewCreated setImage:[UIImage imageNamed:[NSString stringWithFormat:@"image%d.png", randomNumber]]]; [viewCreated addSubview:imageViewCreated]; //[imageViewCreated release]; return [viewCreated autorelease]; But when this code executes only the first subview is animated and resized. The UiimageView moves 200 pixels to the left but does not get resized. NSLog(@"sender tag %i",[sender tag]); UIView *currentView = [self.view viewWithTag:[sender tag]]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:1.5]; currentView.frame = CGRectMake(-200, 0,40, 102); [UIView commitAnimations]; I am pretty sure am I not creating the subviews correctly programmatically, because when I do it in Interface Builder it works as expected. Do I have to do something specific to actually attach the behavior of the second subview to the first subview?

  • - Default value of variables at the time of declaration -

    - by gotye
    Hey guys, I was wondering what was the default values of variables before I intialize them .. For example, if I do : //myClass.h BOOL myBOOL; // default value ? NSArray *myArray; // default value ? NSUInteger myInteger; // default value ? Some more examples here : //myClass.m // myArray is not initialized, only declared in .h file if ([myArray count] == 0) { // TRUE or FALSE ? // do whatever } More generally, what is returned when I do : [myObjectOnlyDeclaredAndNotInitialized myCustomFunction]; Thank you for your answers. Gotye.

  • Getting random objects from an array, and if the objects are the same, get a new object.

    - by XcodeDev
    Hi, I have made a jokes application, where the user generates a joke and the joke will display in a UILabel. However I am trying to randomise the jokes show, but I do not want to show the same joke twice. Please could you tell me how I could do this. I am using the code below to try and do that, but it seems that it is not working. - (IBAction)generateNewJoke { if (i < [jokeArray count]) { i++; [userDefaults setInteger:[userDefaults integerForKey:kNewIndex] forKey:kOldIndex]; int oldnumber = [userDefaults integerForKey:kOldIndex]; int newnumber = [userDefaults integerForKey:kNewIndex]; [answerLabel setText:@""]; [userDefaults setInteger:i forKey:kNewIndex]; if (oldnumber == newnumber) { NSLog(@"they are the same"); [userDefaults setInteger:arc4random()%[jokeArray count] forKey:kNewIndex]; } [jokeLabel setText:[jokeArray objectAtIndex:[userDefaults integerForKey:kNewIndex]]]; } }

  • CAAnimation rotation did not give last stage?

  • Three20 TTSectionedDataSource row height

    - by Ward
    Hey there, I'm using Three20 to create a table with several textfields for user registration. I've found two possible methods using Three20. The first uses the TTSectionedDataSource's tableDidLoadModel method to manually add UI components and the second adds custom items that contains pre formatted UI components. The second option seems way more complex and I'm having a difficult time accessing the individual fields. So if one field is a textfield for the username, I need to access the field to submit the username and it doesn't seem like there's an easy answer. The first option gives me a lot of flexibility, but I can't figure out how to set the individual row heights. One row may have a label above a text field, another may have an image, etc. Is there a method that can be used in TTSectionedDataSource that will allow me to set the height for each row? Thus far, I'm using method one and creating UIViews to hold a label field and a text field. I've tried changing the frame of the uiview before it is added to the items array, but it has no affect. Any ideas?

  • Make UILabel show "No results" instead of "nan"

    - by Mike Rychev
    I have a small app, where user can make some calculations and solve equations. For example, if in a square equation discriminant is less than zero, the x1 and x2 values are "nan", so when I assign x1 and x2 values to UILabels they show "nan" as well. Writing a lot of if's like if(D<0) [label setText:[NSString stringWithFormat: @"No solutions"]]; Doesn't help-there are too many cases. I want to check if after [label setText:[NSString stringWithFormat: @"%f", x]]; label's value is "nan", the label's value will be set to @"No solutions". Doing simple if(label==@"nan") { //code } doesn't help. Thanks in advance!

The problem is that i trimmed all the characters from the nsstring that i didnt want but the weird thing is that i cant get rid of all the whitespace. i used all the techniques i read from other answers but still some whitespace remains. here is my code -(void)requestFinished:(ASIHTTPRequest *)request{ NSString *htmlData = [request responseString]; NSCharacterSet *garbage = [NSCharacterSet characterSetWithCharactersInString:@"qazwsxedcrfvtgbyhnujmik,ol.p;/[]'QAZWSXEDCRFVTGBYHNUJMIKOLP()\"-1234567890#{}=:+_&!`<>"]; //im doing this to remove all characters except non-english chars htmlData = [htmlData compomentsSeparatedByCharactersInSet:garbage ]compomentsJoinedByString:@""]; htmlData = [htmlData stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]; htmlData = [htmlData stringByReplacingOccurencesOfString:@"[\n\t\r ]+" withString@""]; htmlData = [htmlData stringByReplacingOccurencesOfString:@" " withString:@""]; NSLog(@"%@",htmlData); } i get this result: nonenglishwordsnonenglishwords nonenglishwordsnonenglishwords (whitespace or new lines in middle remains) thank you.

  • How do faces in .obj work?

    - by Adl
    Hi When parsing an .obj-file, with vertices and vertex-faces, it is easy to pass the vertices to the shader and the use glDrawElements using the vertex-faces. When parsing an .obj-file, with vertices and texture-coordinates, another type of face occur: texture-coordinate faces. When displaying textures, apart from loading images, binding them and passing texture coordinates into the parser, how to use the texture-coordinate faces? They differ from the vertex-faces and I suppose that the texture-coordinate faces have a purpose when displaying textures? Regards Niclas

  • Problem while adding new Object to CoreData App

    - by elementsense
    Hi Another Day, another CoreData problem,...but hopefully the last one now. Ok here is a copy of what I have : I have a List of Hotel Guests that stay in one Room and have Preferences. Once ready the user should select a guest and see the data and should also be able to add new guest, select the room (maintained also by application) and select their preferences (where the user can also add new preferences). The guest can have no or many preferences. So here is what I have so far. I created 3 Entities : - Rooms with roomnumber - Preferences with name - GuestInfo with name - with these Relationships room (Destination Rooms) and prefs (Destination Preferences with "To-Many Relationship") The prefs is a NSSet when you create a Managed Object Class. Now I created a UITableViewController to display all the data. I also have an edit and add mode. When I add a new Guest and just fill out the name, everything works fine. But when I want to add the prefs or the room number I get this error : Illegal attempt to establish a relationship 'room' between objects in different contexts Now, what confuses me is that when I add a guest and enter just the name, save it, go back and edit it and select the prefs and room number it works ? I have this line in both ViewControllers to select the room or prefs : [editedObject setValue:selectedRoom forKey:editedFieldKey]; with this .h : NSManagedObject *editedObject; NSString *editedFieldKey; NSString *editedFieldName; Again, it works on the editing mode but not when I want to add a fresh object. And to be sure, this is what I do for adding an new Guest : - (IBAction)addNewItem { AddViewController *addViewController = [[AddViewController alloc] initWithStyle:UITableViewStyleGrouped]; addViewController.delegate = self; addViewController.context = _context; // Create a new managed object context for the new book -- set its persistent store coordinator to the same as that from the fetched results controller's context. NSManagedObjectContext *addingContext = [[NSManagedObjectContext alloc] init]; self.addingManagedObjectContext = addingContext; [addingContext release]; [addingManagedObjectContext setPersistentStoreCoordinator:[[_fetchedResultsController managedObjectContext] persistentStoreCoordinator]]; GuestInfo *info = (GuestInfo *)[NSEntityDescription insertNewObjectForEntityForName:@"GuestInfo" inManagedObjectContext:addingContext]; addViewController.info = info; UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:addViewController]; [self.navigationController presentModalViewController:navController animated:YES]; [addViewController release]; [navController release]; } Anything I have to do to initialize the Room or Prefs ? Hope someone can help me out. Thanks

  • Gruber URL Regex tweak to capture "domain.com"

    - by mootymoots
    I found an updated version of John Gruber's regex for url matching in this post by user GianPac, which states it's been adapted to recognize url without protocol or the www part: (?i)\b((?:[a-z][\w-]+:(?:/{1,3}|[a-z0-9%])|www\d{0,3}[.]|[a-z0-9.-]+[.][a-z]{2,4}/?)(?:[^\s()<]+|(([^\s()<]+|(([^\s()<]+)))))(?:(([^\s()<]+|(([^\s()<]+))))|[^\s`!()[]{};:'\".,<?«»“”‘’])) Whilst this works in most cases, I found it does not match "google.com". It does match "google.comm" and "google.co.uk", so this must be a small oversight. The trouble is, I literally hate regex. It's the bane of my life. I just want to try and tweak this one more time to allow for "google.com" - can anyone throw me a pointer? I (think) it's something to do with this part of the code: +[.][a-z]{2,4}/?) ?

  • NSTimer to smooth out playback position

    - by Michael
    I have an audio player and I want to show the current time of the the playback. I'm using a custom play class. The app downloads the mp3 to a file then plays from the file when 5% has been downloaded. I have a progress view update as the file plays and update a label on each call to the progress view. However, this is jerky... sometimes even going backward a digit or two. I was considering using an NSTimer to smooth things out. I would be fired every second to a method and pass the percentage played figure to the method then update the label. First, does this seem reasonable? Second, how do I pass the percentage (a float) over to the target of the timer. Right now I am putting the percent played into a dictionary but this seems less than optimal. This is what is called update the progress bar: -(void)updateAudioProgress:(Percentage)percent { audio = percent; if (!seekChanging) slider.value = percent; NSMutableDictionary *myDictionary = [[NSMutableDictionary alloc] init]; [myDictionary setValue:[NSNumber numberWithFloat:percent] forKey:@"myPercent"]; [NSTimer scheduledTimerWithTimeInterval:5 target:self selector:@selector(myTimerMethod:) userInfo:myDictionary repeats:YES]; [myDictionary release]; } This is called first after 5 seconds but then updates each time the method is called. As always, comments and pointers appreciated.
