  • UIWebView load remote html page with local images and javascript files

    - by BlueNile
    Im creating application that will display remote page on the UIWebView using local images and javascript/css files for faster loading. I want to avoid using cache because for this to work it must first load all the content. I was searching online for possible solution. Here is what I have: NSURLRequest *urlrequest = [ [NSURLRequest alloc] initWithURL: [NSURL URLWithString:urlString] ]; NSData *returnData = [ NSURLConnection sendSynchronousRequest:urlrequest returningResponse: nil error: nil ]; NSString *HTMLData = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; NSString *resourcePath = [[NSBundle mainBundle] resourcePath]; resourcePath = [resourcePath stringByReplacingOccurrencesOfString:@"/" withString:@"//"]; resourcePath = [resourcePath stringByReplacingOccurrencesOfString:@" " withString:@"%20"]; [webView loadHTMLString:HTMLData baseURL: [NSURL URLWithString: [NSString stringWithFormat:@"file:/%@//",resourcePath] ]]; urlString is defined and I moved files to the app bundle. Code works as I can see the remote page but no images nor javascript files are present.

  • Access static Method in GDB

    - by Besi
    I recently discovered the GDB in Xcode which makes up for some functionality which IMHO seems to be lacking in Xcode. So I can do the following in GDB: (gdb) po [LoginManager sharedSession].loginToken 20D52FE9-3573-437E-9A65-846572B63726 However, I have another Service class, which is currently not loaded so I get the following error: (gdb) po [SessionService displaySessionInfoForToken:@"XXX"] No symbol "SessionService" in current context. I don't understand why the LoginManager can be loaded but not the SessionService.

  • UIWebView appears null when calling fro a method

    - by Alexidze
    I have a major problem when trying to access a UIWebView that was created during ViewDidLoad, the UIWebView appears null here is how i declare the property @property (nonatomic, retain) UIWebView *detailsView; the implementation @implementation iPadMainViewController @synthesize detailsView; - (void)viewDidLoad { [super viewDidLoad]; detailsView = [[UIWebView alloc] initWithFrame:CGRectMake(500, 0, 512, 768)]; [self.view addSubView:detailsView]; } When accessing from - (void)loadDetailedContent:(NSString *)s { NSLog(@"%@", detailsView); } I get NULL, is it a normal behavior or am i doing something wrong? here is the touchesBegan that is being called, from the views subclass that is being touched, -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { iPadMainViewController *mycontroller = [[iPadMainViewController alloc] init]; self.delegate = mycontroller; [self.delegate loadDetailedContent:NewsId]; }

  • iPhone/iPad fatal error in C++ code produces no output in the log

    - by morgancodes
    I'm trying to move away from Objective-C to C++ for audio in my iPad programming, due to the a few reports I've heard of Objective-C selectors sometimes causing audio glitches. So I'm starting to use pure C++ files. When a fatal error happens in one of the C++ files, I get no output from the log. The app just crashes. For example, if I do this in my C++ file: env = new ADSR(); cout << "setting env to null\n"; env = NULL; env->setSustainLevel(1); cout << "called function on non-initialized env\n"; I get the following output: setting env to null After that, there's a method called on NULL, which apparently kills the app, but absolutely nothing to that effect is reported. What do I need to do to have useful information logged when there's an error in my C++ code?

  • 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.

  • Change Interval Of CADisplayLink

    - by user3679109
    I have replaced an NSTimer with a CADisplayLink. I have it working properly but it is running too slowly. How could I go about speeding this up? This is the code that I'm using: ViewController.h (In {} with @interface: CADisplayLink *displayLink; ViewController.m (viewDidLoad): displayLink = [CADisplayLink displayLinkWithTarget:self selector:@selector(onTimer)]; [displayLink addToRunLoop:[NSRunLoop currentRunLoop] forMode:NSRunLoopCommonModes]; onTimer is the method that it is calling. So my question is how do I speed up how often this is being called? Thanks

  • didSelectRowAtIndexPath being called after viewDidLoad of the called view

    - by Serguei Fedorov
    I am trying to pass variables over to the new view. I have the following code: appDelegate *dataCenter = (AppDelegate*)[[UIApplication sharedApplication] delegate]; dataCenter.myVariable = [array objectAtIndex:indexPath.row]; in the didSelectRowAtIndexPath of the calling view. However, the issue that I have is that this variable is empty in the vewDidLoad function of the next view, simply because it fired off BEFORE the didSelectRowAtIndexPath of the calling view. I am using storyboard to link the views together. Both are UITableView. If I hit back and then reselect the table element it is then set, granted that by the time I hit back and then selected again, the variable got set. Is there any way to for the order of execution? I really don't want to do UI view switching on the back end. Any help is greatly appreciated!

  • Breaking One Big Graphic of MutablePaths into CAShapeLayers

    - by StackOverFlowRider
    I have a class called GraphicView that takes a Graphic object and draws it in its drawRect method. This Graphic object is basically an array of mutablePaths that comprise an icon that I want drawn. For performance and other issues, I was thinking of taking this icon that is comprised of mutablePaths, and dividing it into a bunch of CAShapeLayers. I'm wondering is this possible? Considering the points for the mutablePaths of the icon are all interwoven together (ie the icon was initially an SVG file that I converted to code), is it possible to divide different parts of the icon into CAShapeLayers, and reassemble them all together when assigning to the views layer? If so how would it be done? If I assign them as sublayers to a CALayer or CAShapeLayer, will it understand to mesh them all together?

  • Different icons and title for same iPad application

    - by trapo
    I'm developing an iPad application that will be distributed "in-house" ie only inside enterprise. They asked me if i can produce 2 different releases of the same application to be installed on the same iPad. The first one will communicate with a production server while the second will use a sandbox server and will be used by user to learn the system. Server url will be changed in app settings. They told me to differentiate these releases by icon and title (and also, of course, by title in navigation bar). What's the best way to get this goal avoiding duplication of the project?

  • UIImage for UIImageView is nil

    - by yeesterbunny
    I'm having problem displaying UIImage in UIImageView. I looked all over stackoverflow for similar questions, but none of the fixes helped me. The image is indeed in my bundle File Inspector - Target Membership is checked for the image IBOutlet is connected (I have tried both using IBOutlet and doing it programmatically) Both png nor jpg works Here's the code for using Interface Builder - //@property and @synthesize set for IBOutlet UIImageView *imageView - (void)viewDidLoad { [super viewDidLoad]; NSAssert(self.imageView, @"self.imageView is nil. Check your IBOutlet connection"); UIImage *image = [UIImage imageNamed:@"banner.jpg"]; NSAssert(image, @"image is nil"); self.imageView.image = image; } This code will terminate with NSAssert, printing in the console that 'image is nil'. I also tried selecting the Image directly from the attributes inspector: However it still doesn't show the image (still terminates with NSAssert - 'image is nil'). Any help or suggestions will be greatly appreciated. Thanks

  • what is the required code method of making a sticker app?

    - by zeropt7
    I am new to photo apps, recently I am interested in making a sticker app like those can be seen in the appstore, I know I would need to use uiimagepickercontroller, uiscrollview and uigesturerecognizer. However I wonder which code method should I use for the app to load multiple stickers? Should it be called programmatically? Is that I would need to use the if-statement, say if one sticker is loaded, the app will auto generate a new sticker on top of it?

  • UITableView overlaps with NavigationBar in Storyboard Setting on first run

    - by Evils
    I know this seems to be a duplicate question which has been around here many many times, but believe me, I tried all iOS7 and earlier fixes which sets the Layout to a different Edge configuration without any change. My Storyboard looks like this: -> Navigation Controller -> Tab Bar Controller -> MyTableViewController -> VCForCellOne With the first run of my application the UITableView overlaps with the source NavigationController as shown here: After clicking on one of my Cells which pushes the corresponding ViewController to the NavigationController and going back again, everything looks fine as shown here: So everything is as it should be after once pushing another ViewController to the NavigationController and then going back. Switching from Portrait to Landscape and back also fixes the layout problem and everything is layed out as it should be. My ViewController within the Storyboard looks like this: I left it the default value, so I don't know what goes wrong here. I hope you understand my problem here. There's no custom class ViewController here, so no additional code which messes up something here. Any help highly appreciated!

  • Navigation Bar color doesn't change back? iOS7

    - by TKP
    I have several tableviews with navigation controller. The navigation bar is white for all the views except the last one, which is red. I have [[[self navigationController] navigationBar] setTintColor:[UIColor redColor]; in the viewDidLoad of the last tableview and [[[self navigationController] navigationBar] setTintColor:[UIColor whiteColor]; in the viewDidLoad of other table views. It works fine until I get to the last view and the color of the navigation bar changes to red. When I go back to the previous views, all the previous views' navigation bar has changed to red. Where should I put those codes so the color will remain unchanged? Thanks,

  • What is the most efficient way to use Core Data?

    - by Eric
    I'm developing an iPad application using Core Data, and was hoping someone could clarify something about Core Data. Right now, I populate my table by making a fetch request for all of my data in viewDidLoad. I'd rather make individual fetch requests in my tableView:cellForRowAtIndexPath:. Can anyone tell me which is more efficient, and why? In other words, is it much less efficient to make lots of small requests as opposed to one big request?

  • adding a UITableView programmatically to a UIViewController

    - by Adam
    I'm loading a UIViewController into one of my Nav controller's hierarchies, which will contain some text and some images. At the bottom, I will want to create a expandable and collapsable tableview. First off, is this idea possible? If it is, how do I add it and where do I place the data source and delegate methods? Can I just make a separate subclass of the TableViewController and then add it to my ViewController as a subview?

  • ViewController Navigating

    - by Kobe.o4
    I have 4 ViewControllers, startViewController as the initial View Controller. This contains my intro. After its finish, it will [self presentViewController:vc animated:YES completion:NULL]; into my menuViewController. startViewController ------> menuViewController ------> C1ViewController \ \ ------> ImportantViewController In my menuViewController are buttons for the two ViewController like the above illustration. Also I presented them in the View with this: [self presentViewController:vc animated:YES completion:NULL]; I return tomenuViewController with this [self dismissModalViewControllerAnimated:YES]; What I wanted is to make the ImportantViewController to be the like the parent view or the mainVIew even if I go to other Views. What I need is when ImportantViewController is presented when I go to either C1ViewController or menuViewController it wont be deallocated, or its content there will still be retained. Is it possible? And How? I don't know much about what parent and child view controllers for so I dont know what to implement in my problem. Thank you. BTW, Im using Storyboard.

  • modifying constants in objective c during run time

    - by moshikafya
    I am trying to solve the following problem. I have the following constants in my header file: #define PREFS_MY_CONSTANT_1 @"bla1" #define PREFS_MY_CONSTANT_2 @"bla2" #define PREFS_MY_CONSTANT_3 @"bla3" ... In one of my functions, I'd like to print to the UIbutton one of those strings based on user input, so say the user inputs '1', i would show bla1. Instead of creating a huge switch (i have 100 of those), I am looking for a way to combine the constant with the variable holding the user input, so something like that ideally: NSInteger input; [button setTitle:PREFS_MY_CONSTANT_{$input} forState: UIControlStateNormal]; Is something like that possible? what would be the best way to solve this?

  • viewForHeaderInSection - create header that would display properly in all cases

    - by sha
    I have an interesting problem/question and i'm not sure if it is even doable. So I have a custom header view for regular UITableView. But it's transparent and it doesn't fill fill table width. So it displayed properly when table is scrolled and this header view is displayed above cell content (sticked to the top). But when same header is displayed between two sections down - it looks ugly, because it's transparent and it's either displayed above black rectangle or above table background. I was wondering is there way to customize header view for when it's stick to the top and when it's not. Or... may be it's possible to specify what needs to be displayed underneath header view when it's between sections. Something like sectionSeparatorView?
