  • Send data to server with GET

    - by coderjoe
    I have made a site where all my highscores from my game are shown. I send the scores from my iphone game to my site using a script made with php. The script works, because if I enter the link produced by my app in my browser the score is added. However I want to send the scores from my app. The script is using the GET method to get name, scores etcetera. This is what i have now: NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:urlString]]; NSError * e; NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&e]; But it's not sending data to my server. The urlString is correct, because if I enter the link produced by my app in my browser the score is added. How can i solve this problem, Thanks in advance

  • Correct way to clear/release an array of arrays

    - by iFloh
    And again my array of arrays .... When I have an array "x" that contains multiple instances of an array "y", how do I clear/release it without risking memory leaks? are the following calls sufficient? (a) clearing the array [x removeAllObjects]; (b) releasing the array [x release]; or do I need to enumerate the array, such as: (c) clearing the array for(int i=0;i<x.count;i++) [[x objectAtIndex:i] release]; [x removeAllObjects]; (d) releasing the array for(int i=0;i<x.count;i++) [[x objectAtIndex:i] release]; [x release]; thanks in advance

  • How to set background color of tableView

    - by Praveen
    Hi Folks, I have tried all the way but could not succeed to set backgroundColor of TableView. setting tableView.backgroundColor and/or cell.backgroundColor to clearColor didn't work when the parent view controller was UIViewContoller. My nib file structure is FileOwner View UITableView (Note: i set the TableView to groupedTable section) First attempt, I created the UIView in the code viewDidLoad UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 160, 300)] autorelease; [view setBackgroundColor:UIColor blueColor]; // color it just to see if it is created at the right place [self.tableView sendSubViewToBack:view]; It works but it hides the content of cell. I am able to see the content of header but not cell content. (But when i change the co-ordinate of view(0,150,160,300) then i am able to see the cell's content but then it loose the backgroundColor of tableview. Second attempt, I created the imageView View ImageView UITableView and set the self.tableView.backgroundColor = [UIColor clearColor]; but did not work. I googled but did not the peaceful answer.

  • Adding procedural C openGL functions to an iPhone project

    - by user309595
    I want to add a few drawing functions to an iPhone project for drawing things. Something like drawTile(x,y,len,wid); which would call openGL to draw a box somewhere. I should just be able to write a procedural C file to do this but the openGL libraries are objective C and I'm getting weird errors. Do I have to make a class for all of my drawing commands and call class methods?

  • Soundboard app: Play sound as long as the user is pressing the button

    - by Pantelis Proios
    I am making a soundboard app and i am using sounds with over 30sec duration. I am playing the sound by connecting in IB my action with a "touch down" event, however the sound keeps playing once started. I connected in the some button a "touch cancel" & "touch up outside" event that is supposed to stop the sound but for some reason it doesn't. Can anybody provide a solution to my problem? ---Edit--- Here is my code: -(IBAction)playSound:(id)sender { NSString *soundFile; soundFile = [[NSBundle mainBundle] pathForResource:@"testSound" ofType:@"mp3"]; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:soundFile] error:nil]; audioPlayer.volume = volumeSlider.value; audioPlayer.numberOfLoops = -1; [audioPlayer prepareToPlay]; [audioPlayer play]; } -(IBAction)stopSound:(id)sender { [audioPlayer stop]; }

  • iPhone Accelerometer Values

    - by Mike
    My question is about the iPhone accelerometer. Does the accelerometer measure acceleration or movement of the iPhone? What I mean is if I hold the iPhone and go from 0mph to 60mph, I would expect the measure of acceleration to increase in value from 0 to 60, but once I reach 60, I expect the value to return to 0 since I am "no longer accelerating" but am moving at a constant speed. Now if the accelerometer measure motion, I would expect it to register 0 to 60 and continue to provide a change in value as I move forward at 60mph. Sorry, I looked at a few books, programmed some code (values seemed to small to give a recognizable result over short distances or speeds), and a lot of web searches, and I am trying to get an answer to this question. Thanx!

  • UIPageViewController blanking page

    - by CrazyEoin
    I've been trying to use the UIPageViewController to display 3 different nibs for a few days on and off now and have almost got it working. I still have one weird bug that I cant figure out. Basically the app starts, I can scroll between the 3 pages one after another with out any problems, eg: Page1-Page2-Page3 and then back to the start: Page3-Page2-Page1. No Problems. The issue is that if I scroll, for example from Page3-Page2, then BACK to Page3, Page3 Dissappears when it snaps into place. If I scroll to where a forth page would be, then I get Page3. Here is the code relevant to the UIPageViewController, the nibs and the delegate methods for the UIPageViewController: - (void)viewDidLoad{ [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. self.pageViewController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil]; self.pageViewController.delegate = self; [[self.pageViewController view] setFrame:[[self view] bounds]]; indexTest = 0; Page1 *p1 = [[Page1 alloc]initWithNibName:@"Page1" bundle:nil]; p1.view.tag = 1; Page2 *p2 = [[Page2 alloc]initWithNibName:@"Page2" bundle:nil]; p2.view.tag = 2; Page3 *p3 = [[Page3 alloc]initWithNibName:@"Page3" bundle:nil]; p3.view.tag = 3; NSArray *arr = [[NSArray alloc] initWithObjects:p1,nil]; viewControllers = [[NSMutableArray alloc] initWithObjects:p1,p2,p3, nil]; [self.pageViewController setViewControllers:arr direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil]; self.pageViewController.dataSource = self; [self addChildViewController:self.pageViewController]; [[self view] addSubview:[self.pageViewController view]]; [self.pageViewController didMoveToParentViewController:self]; self.view.gestureRecognizers = self.pageViewController.gestureRecognizers; } #pragma mark - page view controller stuff - (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController { if (indexTest > 0) { switch (indexTest) { case 1:{ NSLog(@"NO page is BEFORE current page"); break; } case 2:{ NSLog(@"Page BEFORE is Page: %@", [NSString stringWithFormat:@"%@",[viewControllers objectAtIndex:0] ] ); indexTest--; return [viewControllers objectAtIndex:0]; break; } default:{ NSLog(@"PROBLEM in viewBEFORE, indexTest = %d!!!!", indexTest); break; } } } return nil; } - (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController { if (indexTest < NUM_OF_PAGES) { switch (indexTest) { case 0:{ NSLog(@"Page AFTER is Page: %@", [NSString stringWithFormat:@"%@",[viewControllers objectAtIndex:1] ] ); indexTest++; return [viewControllers objectAtIndex:1]; break; } case 1:{ NSLog(@"Page AFTER is Page: %@", [NSString stringWithFormat:@"%@",[viewControllers objectAtIndex:2] ] ); indexTest++; return [viewControllers objectAtIndex:2]; break; } case 2:{ NSLog(@"No pages AFTER this current page %d", indexTest); break; } default:{ NSLog(@"PROBLEM in viewAFTER, indexTest = %d!!!!", indexTest); break; } } } return nil; } Finally the page index dots code #pragma mark - dot controller - (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController { // The number of items reflected in the page indicator. return NUM_OF_PAGES; } - (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController { // The selected item reflected in the page indicator. return 0; } Any and all help is much appreciated, I think I'm just doing something silly that I cant see as I'm so close to it fully working. If anythings not clear or I haven't give enough information please let me know and I'll answer it as best as I can. Thanks

  • UIBezierPath too many paths = too slow?

    - by HHHH
    I have a loop in which I'm adding many (10000+) lines to a UIBezierPath. This seems to be fine, but once I try and render the bezierpath, my device becomes extremely slow and jerky. Is this because I've added too many lines to my path? Adding lines to UIBezierPath - simplified: (this seems fine) [path moveToPoint:CGPointZero]; for (int i = 0; i < 10000; i++ ) { [path addLineToPoint:CGPointMake(i, i)]; } Rendering BeizerPath (Suggested by Rob) - this seems slow. - (void)drawBezierAnimate:(BOOL)animate { UIBezierPath *bezierPath = path; CAShapeLayer *bezier = [[CAShapeLayer alloc] init]; bezier.path = bezierPath.CGPath; bezier.strokeColor = [UIColor blueColor].CGColor; bezier.fillColor = [UIColor clearColor].CGColor; bezier.lineWidth = 2.0; bezier.strokeStart = 0.0; bezier.strokeEnd = 1.0; [self.layer addSublayer:bezier]; if (animate) { CABasicAnimation *animateStrokeEnd = [CABasicAnimation animationWithKeyPath:@"strokeEnd"]; animateStrokeEnd.duration = 100.0; animateStrokeEnd.fromValue = [NSNumber numberWithFloat:0.0f]; animateStrokeEnd.toValue = [NSNumber numberWithFloat:1.0f]; [bezier addAnimation:animateStrokeEnd forKey:@"strokeEndAnimation"]; } } Qs: 1) Is this because I'm adding too many paths too quickly? 2) I want to eventually draw many different lines of different colors, so I assume I would need to create multiple (10000+) UIBezierPaths - would this help or greatly slow the device as well? 3) How would I get around this? Thanks in advance for your help.

  • problem with iOS 4.2 when user press the list view item to go to UIwebview page and the navigation button disappears on the second visit

    - by seahorse
    My app is a Navigation based application. The main menu contains the list view items. if I clicks one of them, it goes to next view which in this case take me to UIwebview embedded web site. Everything is looking great. I can view the content of web page, the navigation control back button which takes to the main menu if I press it. However, I'm having issue when I try to go back to main menu if i visit that subview the second time. It loads the content of UIwebview web page, but the navigation button is gone and won't let me go back to main menu. This problem only appears on latest iOS 4.2 version. Otherwise it works great on 3.1 to 4.1. I would appreciate any hints or inputs. Note this seems not working for subview using UIWebview embedded web content. I don't have any issue with other subviews

  • IPhone library project + UIViews

    - by sig
    I'm trying to refactor some of my iphone code into a library project that can be linked to by several different applications. I made a new iphone library project and copied over some of my classes there, but the project can't build because it doesn't know about stuff like UIView or CGRect. I added in the UIKit, CoreGraphics, and QuartzCore frameworks, but still no go. What am I missing?

  • NSUserDefaults with in-app Settings bundle

    - by Hema Vasudevan
    I'm in the process of building an app and would prefer to have an in-app specific Settings bundle rather than make it available in the Settings application. I'm using NSUserDefaults class to save and retrieve them but would like to have the same Settings app look and feel. I wanted to use InAppSettingsKit or the llamasettings but don't know how to use the NSUserDefaults class. Those kits tell me how to create a .plist file and use their kits. All I need is use the Settings app look and feel while at the same time use NSUserDefaults class to save and retrieve values. Please help.

  • Why do touches only get detected ABOVE my CCBitmapFontAtlas and not ON it? (cocos2d)

    - by RexOnRoids
    I am detecting touches for CCBitmapFontAtlas (just text labels) as shown in the code below. But it seems that touches are only detected slightly ABOVE the CCBitmapFontAtlases?
