  • how do i get a layer's frame to automatically resize based on its superlayer's frame or its view's f

    - by Kevlar
    I'm experimenting with using cagradientlayer to draw gradients in our app instead of having a subclass of uiview manage gradients. One snafu that i've come across is that when the view that has the gradient as a sublayer of its main layer gets resized to fit the data i am trying to show, the layer doesn't resize along with it. I end up having the gradient layer end at the original frame size while my view's frame is much larger. Is there a way to have the sublayer autoresize to fit its superlayer's frame, or the superlayer's view's frame?

  • How to search on a array and display the items on tableview using a searchbar?

    - by skiria
    Hi, I would like to search on a arrays hierachy and display the results on a tableview. The tableview is empty when we run the app and the, when we search it, the data is written. What's the best way to do this? I read tutorials wich explains how it search on a tableview, but i want to search in all of arrays hierachy. I have 3 classes class video //iVars to allocate the video metadata NSInteger videoID; NSString *nameVideo; NSString *nameCategory; NSString *nameTopic; NSString *user; NSString *date; NSString *description; NSString *urlThumbnail; NSString *urlVideo; class Topic NSInteger TopicId; NSString nameTopic; NSMutableArray videos; class Category NSInteger CategoryId; NSString nameCategory NSMutableArray topics AppDelegate NSMutableArray categories

  • Strange behaviour of NSScanner on simple whitespace removal

    - by Michael Waterfall
    I'm trying to replace all multiple whitespace in some text with a single space. This should be a very simple task, however for some reason it's returning a different result than expected. I've read the docs on the NSScanner and it seems like it's not working properly! NSScanner *scanner = [[NSScanner alloc] initWithString:@"This is a test of NSScanner !"]; NSMutableString *result = [[NSMutableString alloc] init]; NSString *temp; NSCharacterSet *whitespace = [NSCharacterSet whitespaceCharacterSet]; while (![scanner isAtEnd]) { // Scan upto and stop before any whitespace [scanner scanUpToCharactersFromSet:whitespace intoString:&temp]; // Add all non whotespace characters to string [result appendString:temp]; // Scan past all whitespace and replace with a single space if ([scanner scanCharactersFromSet:whitespace intoString:NULL]) { [result appendString:@" "]; } } But for some reason the result is @"ThisisatestofNSScanner!" instead of @"This is a test of NSScanner !". If you read through the comments and what each line should achieve it seems simple enough!? scanUpToCharactersFromSet should stop the scanner just as it encounters whitespace. scanCharactersFromSet should then progress the scanner past the whitespace up to the non-whitespace characters. And then the loop continues to the end. What am I missing or not understanding?

  • Autorelease with elements in a UITableViewCell - memory leak

    - by Shaun Budhram
    In my 'cellForRowAtIndexPath' method for a UITableView delegate, I'm allocating a cell if it doesn't exist, and in this cell, I'm creating a new activity spinner like so: UIActivityIndicatorView *actView = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray ] autorelease]; I'm using Leaks to detect memory leaks in my program, and for some reason, this is coming up as a leak, even though it's autoreleasing. The cell itself is also autoreleasing. Has anyone had experience with autoreleasing variables coming up as leaks in the Leaks instrument, and how to tackle these problems? Also, if it helps, this is the history Leaks is displaying for this memory location. It looks like it at some point gets an additional retain message? This is not being done in my code.

  • How to get X,Y,Z rotations of vertices on a sphere at the origin?

    - by Stoff81
    Hey, I have a sphere in my game world and i would like to place a plane at each vertex on this sphere for debugging purposes. The planes should be orientated so that they lie flat against the sphere (perpendicular to the normals). The sphere is located at the origin, so all the vertices are relative to that. If my thinking is correct, i should be able to do this using the positions of the vertices and some simple trigonometry. I have tried a few combinations but have had no joy yet. I would greatly appreciate some help on this. Thanks. Here is my code: float xRot = RADIANS_TO_DEGREES(sinf(vertex.x/PLANET_RADIUS)); float yRot = RADIANS_TO_DEGREES(cosf(vertex.y/PLANET_RADIUS)); glRotatef(xRot, 1.0, 0, 0); glRotatef(yRot, 0, 1.0, 0);

  • Animation of UINavigationController's UIToolbar

    - by Michael Waterfall
    When presenting a view controller that has toolbar items, is it possible for the toolbar to slide in with the view controller (i.e. slide in from the right) as opposed to it sliding from the bottom? In the view controller that is being presented, I've got the toolbar being shown within the -viewWillAppear: method, but the toolbar is being slid up from the bottom of the screen as opposed to it looking like it belongs to the view controller. - (void)viewWillAppear:(BOOL)animated { [self.navigationController setToolbarHidden:NO animated:YES]; ... }

  • Fatsest way to edit alpha of CGImage (or UIImage) with touch and then display?

    - by Pankaj
    I have two image views, one on top of the another, with two different images. As the user touches the image and moves his/her finger, the top image should become transparent along the touch points with a fixed radius. (Like the PhotoChop app). Currently I am doing it this way... For each touch. Get a copy of the image buffer from CGImage of the top image. Edit the alpha channel of the buffer to create a transparent circle centered at the touch point. Create new CGImage from the buffer. Create UIImage from the CGImage and use the new UIImage as the top image view's image. This works but as you can see too many copy, creates are involved and it is slow. Can somebody please suggest me a faster way of doing the same thing?

  • How to stop moving the image in objective c?

    - by user1589452
    I have done a coding to check whether the image crossed particular area or not, -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { CGPoint loc=[touch locationInView:self.view]; if (touch.view==img2Obj) { NSLog(@"image2"); img2Obj.center=loc; currentx1=img2Obj.frame.origin.x; currenty1=img2Obj.frame.origin.y; //NSLog(@"top left corner x and y is %.1f and %.1f",img2Obj.frame.origin.x,img2Obj.frame.origin.y); [self isImg1InPos]; }} -(void)isImg1InPos { int dx,dy; dx=currentx1-x1; dy=currenty1-y1; if (abs(dx)<5 && abs(dx)<5) { NSLog(@"Image must stop moving after this!!!"); [img2Obj setUserInteractionEnabled:FALSE]; } //NSLog(@"unsigned int is %d",abs(dx)); } I want the image to stop moving when when it passes the condition. [img2Obj setUserInteractionEnabled:FALSE]; But its not working, can anyone tell me how to solve this problem Many thanks in advance

  • How to intercept touch events globally?

    - by mystify
    I have an view which is sometimes covered by some other views. However, if the user slides the finger across the screen, I want to slide that underlying view across the screen, too. I could start making custom views for all those covering subviews and forward all kinds of touch events, but that's somewhat cumbersome. Maybe there's some kind of notification or another way that a UIView or UIControl subclass can be aware of touch events happening right now, no matter where they are. In short: I need an UIView subclass or UIControl subclass which knows about any touch events happening on the entire screen. Or at least if tht's not possible, knowing about any touch events happening above itself in the same underlying superview. Another description: There are 20 views, all reside inside the same superview. The first view is covered by 19 others. But if the user slides across the screen, that first view must slide too, so it must be aware of touch events. Is there any better solution that making all 19 views forward touch events? (yes, all 19 views respond to touch events in this example)

  • how to get the image position from pdf file in objective c?

    - by Sarah
    Hello, I am doing something like extracting the pdf text in a string format so as to annotate the text and in the same process i need to find the image positions covered in the same pdf file so as to maintain its position. Now the problem is that i am not getting the exact positions of the images in the same pdf file. Is it possible to use some thing like OCR,if yes,how to use that? Can anybody help me in finding the exact position of the image in the pdf file? I need to implement some pdf reader kind of application for ipad,that's just for the knowledge. Thank you.

  • Uniquing with Existing Core Data Entities

    - by warrenm
    I'm using Core Data to store a lot (1000s) of items. A pair of properties on each item are used to determine uniqueness, so when a new item comes in, I compare it against the existing items before inserting it. Since the incoming data is in the form of an RSS feed, there are often many duplicates, and the cost of the uniquing step is O(N^2), which has become significant. Right now, I create a set of existing items before iterating over the list of (possible) new items. My theory is that on the first iteration, all the items will be faulted in, and assuming we aren't pressed for memory, most of those items will remain resident over the course of the iteration. I see my options thusly: Use string comparison for uniquing, iterating over all "new" items and comparing to all existing items (Current approach) Use a predicate to filter the set of existing items against the properties of the "new" items. Use a predicate with Core Data to determine uniqueness of each "new" item (without retrieving the set of existing items). Is option 3 likely to be faster than my current approach? Do you know of a better way?

  • NSFetchedResultsController didn't return data

    - by Dmitry Kochkin
    Hello! I get stuck in some problem and after 2 days of seeking I've found solution but didn't get idea why does it work. First, I'm initialized NSFetchedResultsController using following code (it look like a lot of automatically generated): - (NSFetchedResultsController *)fetchedResultsController { if (fetchedResultsController != nil) return fetchedResultsController; NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Profile" inManagedObjectContext:self.managedObjectContext]; [fetchRequest setEntity:entity]; [fetchRequest setFetchBatchSize:20]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"lastName" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:self.managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; NSError *error = nil; //[aFetchedResultsController performFetch:&error]; [aFetchedResultsController release]; [fetchRequest release]; [sortDescriptor release]; [sortDescriptors release]; return fetchedResultsController; } Have a look at commented string - there wasn't any of these strings and when I asked for data - I didn't get any (and it was there!). When I've uncommented that line, it starts work. Seems evident, but all examples I saw before hadn't that line. And they work. How can it be? I just want to know what am I doing wrong.

  • Paging a UIScrollView with a large PDF

    - by Fousa
    I try to create a simple UIScrollView with paging. And I want to be able to scroll through a large PDF document, but this gives me some problems... I tried the following options: Convert all the PDF pages to UIImages at startup, this works, but is very slow on start Manually drawing the PDF page in the drawRect, but yet again this was slow... And I prefer not to load everything at startup but to do it during the usage. Did anyone did this recently? Can't seem to find a nice example project. Thnx! Jelle

  • First and last UITableViewCell keep changing while scrolling.

    - by W Dyson
    I have a tableView with cells containing one UITextField as a subview for each cell. My problem is that when I scroll down, the text in the first cell is duplicated in the last cell. I can't for the life if me figure out why. I have tried loading the cells from different nibs, having the textFields as ivars. The UITextFields don't seem to be the problem, I'm thinking it has something to do with the tableView reusing the cells. The textFields all have a data source that keeps track of the text within the textField and the text is reset each time the cell is shown. Any ideas? UPDATE: Thanks guys, here's a sample: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"Section %i, Row %i", indexPath.section, indexPath.row); static NSString *JournalCellIdentifier = @"JournalCellIdentifier"; UITableViewCell *cell = (UITableViewCell *)[self.tableView dequeueReusableCellWithIdentifier:JournalCellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:JournalCellIdentifier] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; cell.accessoryType = UITableViewCellAccessoryNone; } if (indexPath.section == 0) { UITextField *textField = (UITextField *)[self.authorCell viewWithTag:1]; [cell addSubview:textField]; self.authorTextField = textField; self.authorTextField.text = [self.textFieldDictionary objectForKey:@"author"]; NSLog(@"Reading Author:%@", [self.textFieldDictionary objectForKey:@"author"]); } else if (indexPath.section == 1) { UITextField *textField = (UITextField *)[self.yearCell viewWithTag:1]; [cell addSubview:textField]; self.yearTextField = textField; self.yearTextField.text = [self.textFieldDictionary objectForKey:@"year"]; NSLog(@"Reading Year:%@", [self.textFieldDictionary objectForKey:@"year"]); } else if (indexPath.section == 2) { UITextField *textField = (UITextField *)[self.volumeCell viewWithTag:1]; [cell addSubview:textField]; self.volumeTextField = textField; self.volumeTextField.text = [self.textFieldDictionary objectForKey:@"volume"]; NSLog(@"Reading Volume:%@", [self.textFieldDictionary objectForKey:@"volume"]); } return cell; }

    Continued from the last question here: Log method name in Obj-C . I just wondered if there is a way to print out the variable name as well. For example: NSString *name = "vodkhang"; NCLog(@"%@", name); and I hope that the output should be: name: vodkhang Just to summarize the previous post, currently, I can print out the class name, method name and the line number when I call NCLog(@"Hello World"); <ApplicationDelegate:applicationDidFinishLaunching:10>Hello world with #define NCLog(s, ...) NSLog(@"<%@:%d> %@", __FUNCTION__, __LINE__, [NSString stringWithFormat:(s), ##__VA_ARGS__])

  • Custom Header in ASIHTTPREQUEST

    - by Sharon Nathaniel
    Here is my problem. I am using ASIHTTPREQUEST to send request and get response. Now my need of the time is to upload a image,audio , video or docs via PUT method with a custom header . The header takes filename , filesize,sha256sum,username,mediatype,resume as parameters. Here is the code how I am doing that . -(void)uploadFile { NSString *resume =@"0"; NSUserDefaults *userCredentials =[NSUserDefaults standardUserDefaults]; NSString *userName =[userCredentials objectForKey:@"userName"]; NSArray *objects =[NSArray arrayWithObjects:selectedMediaType,delegate.fileName,userName,fileSize,fileSHA256Sum,resume, nil]; NSArray *keys =[NSArray arrayWithObjects:@"mediatype",@"file_name",@"usrname",@"filesize",@"sha256sum",@"resume", nil]; discSentValue =[NSDictionary dictionaryWithObjects:objects forKeys:keys]; NSURL *url = [NSURL URLWithString:@"http://briareos.code20.com/putmedia.php"]; uploadMedia = [ASIFormDataRequest requestWithURL:url]; [uploadMedia addRequestHeader:@"MEDIA_UPLOAD_CUSTOM_HEADER" value:[discSentValue JSONRepresentation]]; [uploadMedia setData:dataToUpload forKey:@"File"]; [uploadMedia setDelegate:self]; [uploadMedia setRequestMethod:@"PUT"]; [uploadMedia startAsynchronous]; } But the server is unable to recognize the header , it always returns "invalid header"
