  • Core Plot: only works ok with three plots

    - by Luis
    I am adding a scatter plot to my app (iGear) so when the user selects one, two or three chainrings combined with a cogset on a bike, lines will show the gears meters. The problem is that Core Plot only shows the plots when three chainrings are selected. I need your help, this is my first try at Core Plot and I'm lost. My code is the following: iGearMainViewController.m - (IBAction)showScatterIpad:(id)sender { cogsetToPass = [NSMutableArray new]; arrayForChainringOne = [NSMutableArray new]; arrayForChainringTwo = [NSMutableArray new]; arrayForChainringThree = [NSMutableArray new]; //behavior according to number of chainrings switch (self.segmentedControl.selectedSegmentIndex) { case 0: // one chainring selected for (int i = 1; i<= [cassette.numCogs intValue]; i++) { if (i <10) { corona = [NSString stringWithFormat:@"cog0%d",i]; }else { corona = [NSString stringWithFormat:@"cog%d",i]; } float one = (wheelSize*[_oneChainring.text floatValue]/[[cassette valueForKey:corona]floatValue])/1000; float teeth = [[cassette valueForKey:corona] floatValue]; [cogsetToPass addObject:[NSNumber numberWithFloat:teeth]]; [arrayForChainringOne addObject:[NSNumber numberWithFloat:one]]; } break; case 1: // two chainrings selected for (int i = 1; i<= [cassette.numCogs intValue]; i++) { if (i <10) { corona = [NSString stringWithFormat:@"cog0%d",i]; }else { corona = [NSString stringWithFormat:@"cog%d",i]; } float one = (wheelSize*[_oneChainring.text floatValue]/[[cassette valueForKey:corona]floatValue])/1000; //NSLog(@" gearsForOneChainring = %@",[NSNumber numberWithFloat:one]); float two = (wheelSize*[_twoChainring.text floatValue]/[[cassette valueForKey:corona]floatValue])/1000; [cogsetToPass addObject:[NSNumber numberWithFloat:[[cassette valueForKey:corona]floatValue]]]; [arrayForChainringOne addObject:[NSNumber numberWithFloat:one]]; [arrayForChainringTwo addObject:[NSNumber numberWithFloat:two]]; } break; case 2: // three chainrings selected for (int i = 1; i<= [cassette.numCogs intValue]; i++) { if (i <10) { corona = [NSString stringWithFormat:@"cog0%d",i]; }else { corona = [NSString stringWithFormat:@"cog%d",i]; } float one = (wheelSize*[_oneChainring.text floatValue]/[[cassette valueForKey:corona]floatValue])/1000; float two = (wheelSize*[_twoChainring.text floatValue]/[[cassette valueForKey:corona]floatValue])/1000; float three = (wheelSize*[_threeChainring.text floatValue]/[[cassette valueForKey:corona]floatValue])/1000; [cogsetToPass addObject:[cassette valueForKey:corona]]; [arrayForChainringOne addObject:[NSNumber numberWithFloat:one]]; [arrayForChainringTwo addObject:[NSNumber numberWithFloat:two]]; [arrayForChainringThree addObject:[NSNumber numberWithFloat:three]]; } default: break; } ScatterIpadViewController *sivc = [[ScatterIpadViewController alloc]initWithNibName: @"ScatterIpadViewController" bundle:nil]; [sivc setModalTransitionStyle:UIModalTransitionStyleFlipHorizontal]; sivc.records = [cassetteNumCogs integerValue]; sivc.cogsetSelected = self.cogsetToPass; sivc.chainringOne = self.arrayForChainringOne; sivc.chainringThree = self.arrayForChainringThree; sivc.chainringTwo = self.arrayForChainringTwo; [self presentViewController:sivc animated:YES completion:nil]; } And the child view with the code to draw the plots: ScatterIpadViewController.m #pragma mark - CPTPlotDataSource methods - (NSUInteger)numberOfRecordsForPlot: (CPTPlot *)plot { return records; } - (NSNumber *)numberForPlot: (CPTPlot *)plot field:(NSUInteger)fieldEnum recordIndex:(NSUInteger)index{ switch (fieldEnum) { case CPTScatterPlotFieldX: return [NSNumber numberWithInt:index]; break; case CPTScatterPlotFieldY:{ if ([plot.identifier isEqual:@"one"]==YES) { //NSLog(@"chainringOne objectAtIndex:index = %@", [chainringOne objectAtIndex:index]); return [chainringOne objectAtIndex:index]; }else if ([plot.identifier isEqual:@"two"] == YES ){ //NSLog(@"chainringTwo objectAtIndex:index = %@", [chainringTwo objectAtIndex:index]); return [chainringTwo objectAtIndex:index]; }else if ([plot.identifier isEqual:@"three"] == YES){ //NSLog(@"chainringThree objectAtIndex:index = %@", [chainringThree objectAtIndex:index]); return [chainringThree objectAtIndex:index]; } default: break; } } return nil; } The error returned is an exception on trying to access an empty array. 2012-11-15 11:02:42.962 iGearScatter[3283:11603] Terminating app due to uncaught exception 'NSRangeException', reason: ' -[__NSArrayM objectAtIndex:]: index 0 beyond bounds for empty array' First throw call stack: (0x1989012 0x1696e7e 0x192b0b4 0x166cd 0x183f4 0x1bd39 0x179c0 0x194fb 0x199e1 0x43250 0x14b66 0x13ef0 0x13e89 0x3b5753 0x3b5b2f 0x3b5d54 0x3c35c9 0x5c0814 0x392594 0x39221c 0x394563 0x3103b6 0x310554 0x1e87d8 0x27b3014 0x27a37d5 0x192faf5 0x192ef44 0x192ee1b 0x29ea7e3 0x29ea668 0x2d265c 0x22dd 0x2205 0x1)* libc++abi.dylib: terminate called throwing an exception Thank you!

  • Implementing a multimap in Swift with Arrays and Dictionaries

    - by stuffy
    I'm trying to implement a basic multimap in Swift. Here's a relevant (non-functioning) snippet: class Multimap<K: Hashable, V> { var _dict = Dictionary<K, V[]>() func put(key: K, value: V) { if let existingValues = self._dict[key] { existingValues += value } else { self._dict[key] = [value] } } } However, I'm getting an error on the existingValues += value line: Could not find an overload for '+=' that accepts the supplied arguments This seems to imply that the value type T[] is defined as an immutable array, but I can't find any way to explicitly declare it as mutable. Is this possible in Swift?

  • Attaching javascript events to form widgets

    - by user334017
    I have a form with a drop down menu and I want to do a javascript action whenever the user changes the selection. I imagine it is possible find the input later, using javascript, and attach an event to to it; but it seems like it would be easier if there was some sort of attribute or option that could be defined in form-configure(): e.g. $this->widgetSchema['menu'] = new sfWidgetFormChoice(array( ... 'onclick' => javascript function )); obviously this doesn't work, and it probably wouldn't be an onclick method either, but my question is how do you attach a javascript event to a input/widget?

    - by Paritosh Praharaj
    I'm trying to build a Rails app where I have to access the Zomato API Could anybody guide me on how to create the Controller and View. Suppose I want to get the name of the restaurant from this URL: Restaurant, how do I write the controller and views for it. Currently, I'm using HTTParty gem. This is my controller code: def restaurants @response = HTTParty.get("https://api.zomato.com/v1/restaurant.json/773", :headers => {"X-Zomato-API-Key" => "MYAPIKEY"}) puts response.body, response.code, response.message, response.headers.inspect @categories = Category.where(:category_name => 'Restaurants') end And I'm trying to get the response object in the view: <%= @response.each do |item| %> <td><%= item.id %></td> <td><%= item.name %></td> <td><%= item.url %></td> <% end %> So, this shows the following error: undefined method 'id' for ["id", 773]:Array

  • How to query_posts after the current timestamp and sort reverse chronologically?

    - by Jody Heavener
    I am using the following code in Wordpress to query events (custom post type) and order them by date chronologically.. query_posts( array( 'post_type' => 'events', 'showposts' => 10, 'orderby' => 'meta_value_num','meta_key' => '_ecmb_datetime' ) ); Where the meta key _ecmb_datetime is, this is the timestamp of the event. I don't want to show events that have already happened, so my question is how do I only show events happening after my current time, and how do I sort reverse chronologically? Any help is greatly appreciated

  • Mysql advanced SELECT, or multiple SELECTS? Movies keywords

    - by Supyxy
    I have a mysql database with movies as follows: MOVIES(id,title) KEYWORDS_TABLE(id,key_id) [id is referenced to movies.id, key_id is refernced to keywords.id] KEYWORDS(id,keyword) //this doesn't matter on my example.. Basically i have movies with their titles and plot keywords for each one, i want to select all movies that have the same keywords with with a given movie id. I tried something like: SELECT key_id FROM keywords_table WHERE id=9 doing that in php and storing all the IDs in an array $key_id.. then i build another select that looks like: SELECT movies.title FROM movies,keywords_table WHERE keywords_table.key_id=$key_id[1] OR keywords_table.key_id=$key_id[2] OR ......... OR keywords_table.key_id=$key_id[n] This kinda works but it takes too much time as we talk about a database with thousands of thousands of records. So, any suggestions?? thanks!

  • Safe executing shell scripts; escaping vars before execution.

    - by Kirzilla
    Hello, Let's imagine that we have a simple php script that should get ssh_host, ssh_username, ssh_port from $_GET array and try to connect using this parameters to SSH. $port = escapeshellcmd($_GET['ssh_port']); $host = escapeshellcmd($_GET['ssh_host']); $username = escapeshellcmd($_GET['ssh_username']); $answer = shell_exec("ssh -p " . $port . " " . $user . "@" . $host); Is escapeshellcmd() enough or I need something more tricky? Or maybe I should use escapeshellarg() in this example? Thank you.

  • CodeIgniter's Scaffolding not working

    - by 01010011
    Hi, I keep getting a 404 Page Not Found whenever I try to access CodeIgniter's Scaffolding page in my browser, like so: localhost/codeignitor/index.php/blog/scaffolding/mysecretword I can access localhost/codeignitor/index.php/blog just fine. I followed CodeIgnitor's instructions in their "Create a blog in 20 minutes" by storing my database settings in the database.php file; and automatically connecting to the database by inserting "database" in the core array of the autoload.php; and I've added both parent::Controller(); and $this-load-scaffolding('myTableName') to blog's constructor. It still gives me this 404. Any suggestions?

  • Chrome Extension Manifest 'Matches'

    - by Aristotle
    I'm trying my hands at a simple Chrome Extension, but am running into a problem with providing a value for the matches array in my content_scripts. { "name": "My Extension", "version": "1.0", "description": "My Extension Experiment", "browser_action": { "default_icon": "icon.png", "default_title": "Ext", "default_popup": "popup.html" }, "content_scripts": { "matches": ["http://*"], "js": ["scripts.js"] } } When I try to load this extension into Chrome, I get the following message: Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'.Invalid value for 'content_scripts'. I cannot see what is "invalid" about my value though. What I'm trying to do is match every URL, so my extension can manipulate the DOM (via javascript within scripts.js) of any page it is ran on. Am I missing something, going about this all wrong, or what? update After posting this question, I did notice that the Google example was slightly different than mine, so I modified my code a bit to reflect their syntax: "content_scripts": [{ "matches": ["http://*"], "js": ["scripts.js"] }] That being said, I still get the following error when trying to load my extension: Could not load extension from 'C:\Users\foo\Desktop\Extensions\bar'. Invalid value for 'content_scripts[0].matches[0]'.

  • using KVO to filter an NSTableView using NSPredicate (with arrays)

    - by KingRufus
    My UI is not updating when I expect it to. The application displays "projects" using a view similar to iTunes -- a source list on the left lets you filter a list (NSTableView) on the right. My filters update properly when they are examining any simple field (like name, a string), but not for arrays (like tags). I'm removing a tag from one of my objects (from an NSMutableArray field called "tags") and I expect it to disappear from the list because it no longer matches the predicate that is bound to my table's NSArrayController. ProjectBrowser.mm: self.filter = NSPredicate* srcPredicate = [NSPredicate predicateWithFormat:@"%@ IN %K", selectedTag, @"tags"]; Project.mm: [self willChangeValueForKey:@"tags"]; [tags removeAllObjects]; [self didChangeValueForKey:@"tags"]; I've also tried this, but the result is the same: [[self mutableArrayValueForKey:@"tags"] removeAllObjects]; Interface Builder setup: a ProjectBrowser object is the XIB's File Owner an NSArrayController (Project Controller) has its Content Array bound to "File's Owner".projects Project Controller's filter predicate is bound to "File's Owner".filter NSTableView's column is bound to "Project Controller".name

  • What is a read only collection in C#?

    - by acidzombie24
    I ran a security code analyst i found myself having a CA2105 warning. I looked at the grade tampering example. I didnt realize you can assign int[] to a readonly int. I thought readonly was like the C++ const and makes it illegal. The How to Fix Violations suggest i clone the object (which i dont want to do) or 'Replace the array with a strongly typed collection that cannot be changed'. I clicked the link and see 'ArrayList' and adding each element one by one and it doesnt look like you can prevent something adding more. So when i have this piece of code what is the easiest or best way to make it a read only collection? public static readonly string[] example = { "a", "b", "sfsdg", "sdgfhf", "erfdgf", "last one"};

  • strategy for observer pattern?

    - by fayer
    I want to use observer pattern for a logging system. We have got logObservers and logObservables. The class that will have to log something will implement iLogObservable and include these methods: private $logObservers = array(); public function addLogObserver($logObserver) { $this->logObservers[] = $logObserver; } public function removeLogObserver($logObserver) { $this->logObservers[] = $logObserver; } public function write($type, $message) { foreach($this->logObservers as $logObserver) { $logObserver->log($level, $message); ; } } Then I noticed, that a lot of classes that will use logging will have these methods and I have to copy paste. So isn't it better to have these methods in a class I call LogObservable or just Log and then use strategy (instantiate this class inside all classes that will have to log). When I change the methods in Log, all logObservables will be affected. However, I have not seen anyone use observer pattern with strategy pattern yet, but it seems to be very efficient and remove the duplications. What do you think?

  • Is is better to store serialized data or raw html in mysql?

    - by Yegor
    I de-normalized my database, since the application was crawling otherwise, and Im storing a list of categories for each item in the DB as a raw html version, and simply echoing it out in my design. Each category is actually a link, which is include a tag. Naturally, this is abit of a pain, especially if I want to change the look of how the category links are displayed, since I gotta update all the old cached entries. What if I were to store this data as a serialized array instead, and simply unserialize it, and then apply formatting to it in php. Would there be a significant performance decrease over simply echoing out the raw html?

  • Calling UITableViews delegate methods directly.

    - by RickiG
    Hi I was looking for a way to call the edit method directly. - (void)tableView:(UITableView *)theTableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath I have all my logic for animating manipulated cells, removing from my model array etc. in this method. It is getting called when a user swipes, adds or rearranges, but I would like to call it manually/directly as a background thread changes my model. I have constructed an NSIndexPath like so: NSIndexPath *path = [NSIndexPath indexPathForRow:i inSection:1]; I just can't figure out how to call something like: [self.tableview commitEditingStyle:UITableViewCellEditingStyleDelete forRowAtIndexPath:path]; Do I need to gain access to the methods of this plain style UITableView in another way? Thanks:)

  • Add UIView Above All Other Views, Including StatusBar

    - by Mike Stead
    I'm wanting to create a view (UIControl) which blocks all input and shows a UIActivityIndicatorView while authenticating a user. The UIActionSheet and UIAlertView both manage to add a black semi-transparent view over the top of all other views to block input and I'd like to do similar. I've tried adding my view to the top UIWindow in the [[UIApplication sharedApplication] windows] array, and while this does place it above the UIKeyboard if it's visible, it doesn't place it over the StatusBar (which makes sense). My next attempt was to extend UIAlertView, remove all of its subviews and set its layer.contents = nil, then add the ActivityIndicator as a subview. This works well, but I can't seem to kill the default bouncy transition of the UIAlertView when you call it to "show". Does anyone have any pointers towards the best way tackle this problem that gives me full control? Oh and I know blocking input is not great but I do ensure it's for a short period of time and it has the benefit of making it clear to the user that their action, which must complete for them to progress, is processing.

  • Sqlite3 Database versus populating Arrays

    - by Kenoy
    hi, I am working on a program that requires me to input values for 12 objects, each with 4 arrays, each with 100 values. (4800) values. The 4 arrays represent possible outcomes based on 2 boolean values... i.e. YY, YN, NN, NY and the 100 values to the array are what I want to extract based on another inputted variable. I previously have all possible outcomes in a csv file, and have imported these into sqlite where I can query then for the value using sql. However, It has been suggested to me that sqlite database is not the way to go, and instead I should populate using arrays hardcoded. Which would be better during run time and for memory management?
