  • Incorrect Coordinates From getLocationOnScreen/getLocationInWindow

    - by nimph
    A call to getLocationOnScreen() or getLocationInWindow() both give me a top/Y coordinate that is about ~30px (status/notifications bar's height) too far down. The left/X coordinate is dead on. As I hinted above, I believe the difference is because of the status/notification bar... I could be wrong. I think I can solve this if I can determine the size of the notification bar but, I'm having trouble doing just that. Any help would be greatly appreciated.

  • iPhone 3.0 WebView Scroll PDF Error - [NSCFDictionary _absoluteLinkURL]

    - by DFG
    I have a WebView which loads a PDF file: [myWebView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:fileName ofType:@"pdf"]isDirectory:NO]]]; It works fine on iPhone OS 2.x but on iPhone 3.0, when I tap the PDF for scrolling, this error appears, and the app crash: -[NSCFDictionary _absoluteLinkURL]: unrecognized selector sent to instance 0x1c0230 Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSCFDictionary _absoluteLinkURL]: unrecognized selector sent to instance 0x1c0230'

  • Objective-C partial implementation of classes in separate files

    - by Aran Mulholland
    I am using core data and am generating classes from my data model. I implement custom methods in these classes, however when i regenerate i generate over the top so i end up copying and pasting a bit. What i would like to do is split my implementation files ('.m') so i can have one header file with multiple '.m' files. then i can keep my custom methods in one and not have to worry about erasing them when i regenerate. I use this technique in .NET a lot with its partial keyword. Is there anything similar in objective-C

  • Accessing Private Frameworks to see what they do...

    - by Moshe
    I am investigating the UIFont thing on iPhone. (You can't easily use custom fonts.) I was wondering if the peeking at the Quarts drawing methods would help. The issue is, i don't know where to look or how to access that information. Where can I find the framework headers? Also, I was wondering where the iPhone stores the Fonts. (Path to them...)

  • Problem with UIScrollView

    - by leon
    Hi, Sorry for long winded post. I am trying to understand UIScrollView and running into very simple problem. I am creating a scroll view I am making this view 1.5 size larger then normal size Using UIScrollView I expect to see some edge elements of view out of bounds, but should be able to pan the view therefore bringing missing elements back to the visible area. However I am seeing that I can't just pan/scroll view anyway I want, instead view always wants to scroll up, as soon as move away my finger from the screen (touch end event). I am not handling any touches, etc - I just want to understand why does not scaled view stay put where I scroll it? CGRect viewFrame = self.view.frame ; viewFrame.size.width *= 1.5; viewFrame.size.height *= 1.5; CGSize mySize = viewFrame.size; [ ((UIScrollView *) self.view) setContentSize: mySize]; self.view.transform = CGAffineTransformMakeScale(1.5, 1.5); What I really trying to accomplish is something similar to Number on iPad (the same code will work on iPhone): There is a view with lots of controls on it (order entry form) User can zoom into the entire form so all elements look bigger user can pan the form therefore bringing various elements into the visible area of the screen. It seems that UIScrollView can should be able to handle zoom and pan actions (for now I am using Affine Transform to zoom in to the order entry form and iPad) Thanks

  • Problem with DWR and Android-Browser

    - by moxn
    Hello everyone, I am experiencing a problem with accessing an application from the Android-browser. The application uses DWR to persist connections to the clients that are connected with it. Everything works fine for me, except that if the application does not send any data to the client on the Android-phone for 2 minutes, the connection seems to be lost and no data arrive at the client. The same scenario works just fine on Firefox, Opera and Chrome. If the pause between two data transfers is less than 2 minutes, it works just fine. So, now my question: Is there some timeout setting for the android browser that I am missing? Or is this some built-in bug/feature/whatever that I cannot circumvent? I know that I could prevent this from happening with some sort of heartbeat, I would just like to why this is happening. Thanks in advance, Max btw: Everything (server, clients) runs on my machine and I am testing this on the android emulator with Windows XP Android emulator version 1.10 (build_id CUPCAKE-150240)

  • Understanding CABasicAnimation when spinning an object from a random angle....

    - by user157733
    I have spent ages trying to figure this out and I am still having problems. I want to rotate an image a random number of time - say 5 and a bit - then have it stop. I then want to rotate it again FROM ITS STOPPED POSITION. I am having difficulty with this so maybe someone can advise me on the right way to do it. Ok so I am using a CABasicAnimation for the spin like this... CABasicAnimation* rotationAnimation; rotationAnimation = [NSNumber numberWithFloat: 0.0]; rotationAnimation.toValue = [NSNumber numberWithFloat: M_PI * 1.0]; rotationAnimation.duration = 100; rotationAnimation.cumulative = YES; rotationAnimation.repeatCount = 5.2; rotationAnimation.removedOnCompletion = NO; rotationAnimation.fillMode = kCAFillModeForwards; [myView.layer addAnimation:rotationAnimation forKey:@"rotationAnimation"]; This works fine. I use a animationDidStop function to transform the image to the new angle so that it actually in the new position (not just appearing that way). This is where my problems start. I have tried the following... removing the toValue line which means the animation starts from where it currently is but when the animation block is repeated it jumps back to this start position every time the block is run storing the value of the end rotation and using this in the toValue so the 2 lines of code become... rotationAnimation = [NSNumber numberWithFloat: previousVal]; rotationAnimation.toValue = [NSNumber numberWithFloat: (M_PI * 1.0)+previousVal]; when I do this the animation still jumps because it is flicking back to the previousVal everytime the block is repeated Therefore my final thought is to check to see if the image is at zero, if not then rotate it to zero, then impliment the block of code to spin multiple times. This seems complicated but is this the ONLY way to achieve this? I am concerned about getting the timings smooth with this method. Any suggestions would be amazing! Thanks

  • passing user from UITableView to UIWebView based on selection

    - by ct2k7
    Hello, I'm trying to pass the user on to the interface based on their cell selection in the UITableView, ie, if the user selects cell 1, they are taken to view model 2, containing UIWebView. UIWebView then displays local file, cell1.html. Currently, I've manage to get placeholder using: selectedCellText.text = selectedCell; to display the name of the cell selected. How do I get it to directly pass to the UIWebView, stick UIWebView in the interface and link it using: UIWebView *myWebView = [[UIWebView alloc] initWithFrame:frame]; NSBundle *mainBundle = [NSBundle mainBundle]; NSString *stringUrl = [mainBundle pathForResource:@"selectedCell" ofType:@"html"]; NSURL *baseUrl = [NSURL fileURLWithPath:stringUrl]; NSURLRequest *urlRequest = [NSURLRequest requestWithURL:baseUrl]; [myWebView loadRequest:urlRequest]; My other issue is that some of the cell names have spaces in them, and for simplicity, I'd like to ensure that there are no spaces (actually, will it even work with spaces in the name, I assume with %20 ? Thanks

  • when is a push notification old?

    - by hookjd
    I have noted that when the iPhone OS receives a push notification, it considers that a user action to click on the action button as a "response" to the push notification for some indefinite period of time. If the user lets the push notification sit on screen for a number of seconds, or lets the phone go to sleep, the phone no longer considers the users action as a response to the push notification itself, and therefore does not launch the corresponding app. So my question is... does anyone know what the precise definition from the iPhone OS is as to how long the phone considers a push notification response to be corresponding to the push? Sorry, I can't find a great way to phrase this question, but I hope it makes sense. I'm guessing its something like 20 seconds from my testing, but I don't see this specifically documented anywhere.

    Hi! I was wondering if I can deallocate the depth buffer in iPhone OpenGL ES to conserve memory? Or it stays until the application finishes? I only need the depth testing in the beginning of the application.

  • extract data from Plist to array and dictionary

    - by Boaz
    Hi I made a plist that looks like that: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList 1.0.dtd"> <plist version="1.0"> <array> <array> <dict> <key>Company</key> <string>xxx</string> <key>Title</key> <string>VP Marketing</string> <key>Name</key> <string>Alon ddfr</string> </dict> <dict> <key>Name</key> <string>Adam Ben Shushan</string> <key>Title</key> <string>CEO</string> <key>Company</key> <string>Shushan ltd.</string> </dict> </array> <array> <dict> <key>Company</key> <string>xxx</string> <key>Title</key> <string>CTO</string> <key>Name</key> <string>Boaz frf</string> </dict> </array> </array> </plist> Now I want to extract the data like that (all the 'A' for key "Name" to one section and all the 'B' "Name" to other one): NSString *plistpath = [[NSBundle mainBundle] pathForResource:@"PeopleData" ofType:@"plist"]; NSMutableArray *attendees = [[NSMutableArray alloc] initWithContentsOfFile:plistpath]; listOfPeople = [[NSMutableArray alloc] init];//Add items NSDictionary *indexADict = [NSDictionary dictionaryWithObject:[[attendees objectAtIndex:0] objectForKey:@"Name"] forKey:@"Profiles"]; NSDictionary *indexBDict = [NSDictionary dictionaryWithObject:[[attendees objectAtIndex:1] objectForKey:@"Name"] forKey:@"Profiles"]; [listOfPeople addObject:indexADict]; [listOfPeople addObject:indexBDict]; This in order to view them in sectioned tableView. I know that the problem is here: NSDictionary *indexADict = [NSDictionary dictionaryWithObject:[[attendees objectAtIndex:0] objectForKey:@"Name"] forKey:@"Profiles"]; But I just can't figure how to do it right. Thanks.

  • Why is my app running

    - by John Smith
    I have compiled my iPhone app with setting (Device, Release). I install it on the test machine and it runs with no problem. Here's the problem. The app is linked to a C++ library. The compilation on the simulator has no errors. However the device compilation produces 568 errors, mostly about different visibilities w.r.t AppDelegate.o. They all look like: QL::Error::~Error()has different visibility (default) in /QL/build/Release-iphoneos/libQLLibrary.a(abcd.o) and (hidden) in /Programming/ObjC/Second/build/Second.build/Release-iphoneos/FG.build/Objects-normal/armv6/AppDelegate.o Why is this, and how can I stop the errors anyway?

  • Union with LINQ to XML

    - by Ryan Riley
    I need to union two sets of XElements into a single, unique set of elements. Using the .Union() extension method, I just get a "union all" instead of a union. Am I missing something? var elements = xDocument.Descendants(w + "sdt") .Union(otherDocument.Descendants(w + "sdt") .Select(sdt => new XElement( sdt.Element(w + "sdtPr") .Element(w + "tag") .Attribute(w + "val").Value, GetTextFromContentControl(sdt).Trim()) ) );

  • Leak - GeneralBlock-3584

    - by lamicka
    When i try to check leaks of my iPhone App using Instruments, everything is just fine. Same App on actual real device shows this leak for a few times during the app launch. It is pretty non-deterministic and it happens in system libraries. I tried to google down the solution without a luck. Anyone experiencing the same problems? Anyone knows the solution? I find interesting, that every of my leak in code will crash the app sooner or later. These GeneralBlock-3584 leaks keeps app perfectly stable. Might this be reason for AppStore rejection? Thanx for any answer regarding this undocumented problem (Apple is silent unfortunately).

  • Adding view to UIScrollView and toggling scrolling/interacting

    - by Peter Hajas
    Hi all! I have a UIScrollView in my project. I have a view controller I would like to add as a child of the UIScrollview. Would I just do that like this: [scrollView addSubview:theViewController.view]; or is there a better way? (theView is a view, not the TV show) Furthermore, I would like to be able to use a UIButton in scrollView's parent view controller to toggle whether or not the user is scrolling with scrollView and NOT interacting with theView or NOT scrolling with scrollview and interacting with theView. Should I just have that set the property: scrollView.userInteractionEnabled = NO; or would that disable interaction with theView because it's a child? Thanks for your help!
