  • programmatically change device orientation in iphone

    - by iPhoneDev
    I have navigation based app, when I click on any row in root view, the next view should come in Landscape mode. I am not able to find a proper way to implement this. What I tried is: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return UIInterfaceOrientationIsLandscape(interfaceOrientation); } But this is not working. The view should open only in Landscape mode (not when user rotate it). Can any one help me. Thanks

  • Decimal numbers works in iPhone simulator but NOT on iPhone device

    - by matsoftware
    Hi everybody, I noticed a weird behaviour of iPhone OS when using decimal values. The simulator parse them from strings in a correct way but when I test the app on my iPhone it lose the decimal part. In particular, I store values in a dictionary that I retrieve in this way: Code: NSString *thickStr = [dictionary valueForKey:@"thickness"]; NSNumber *thickNum = [[[self class] numberFormatter] numberFromString:thickStr]; [self setSpessore:thickNum]; where the "numberFormatter" class is defined as below: Code: + (NSNumberFormatter *)numberFormatter { static NSNumberFormatter *_formatter; if (_formatter == nil) { _formatter = [[NSNumberFormatter alloc] init]; [_formatter setNumberStyle:NSNumberFormatterDecimalStyle]; [_formatter setFormatterBehavior:NSNumberFormatterBehavior10_4]; [_formatter setGeneratesDecimalNumbers:TRUE]; } return _formatter; } But it doesn't work! The App on iPhone keeps on convert the string to a simple integer, forgetting the decimal part, while the app on iPhone simulator works fine!

  • Core Plot never stops asking for data, hangs device

    - by Ben Collins
    I'm trying to set up a core plot that looks somewhat like the AAPLot example on the core-plot wiki. I have set up my plot like this: - (void)initGraph:(CPXYGraph*)graph forDays:(NSUInteger)numDays { self.cplhView.hostedLayer = graph; graph.paddingLeft = 30.0; graph.paddingTop = 20.0; graph.paddingRight = 30.0; graph.paddingBottom = 20.0; CPXYPlotSpace *plotSpace = (CPXYPlotSpace*)graph.defaultPlotSpace; plotSpace.xRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(0) length:CPDecimalFromFloat(numDays)]; plotSpace.yRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(0) length:CPDecimalFromFloat(1)]; CPLineStyle *lineStyle = [CPLineStyle lineStyle]; lineStyle.lineColor = [CPColor blackColor]; lineStyle.lineWidth = 2.0f; // Axes NSLog(@"Setting up axes"); CPXYAxisSet *xyAxisSet = (id)graph.axisSet; CPXYAxis *xAxis = xyAxisSet.xAxis; // xAxis.majorIntervalLength = CPDecimalFromFloat(7); // xAxis.minorTicksPerInterval = 7; CPXYAxis *yAxis = xyAxisSet.yAxis; // yAxis.majorIntervalLength = CPDecimalFromFloat(0.1); // Line plot with gradient fill NSLog(@"Setting up line plot"); CPScatterPlot *dataSourceLinePlot = [[[CPScatterPlot alloc] initWithFrame:graph.bounds] autorelease]; dataSourceLinePlot.identifier = @"Data Source Plot"; dataSourceLinePlot.dataLineStyle = nil; dataSourceLinePlot.dataSource = self; [graph addPlot:dataSourceLinePlot]; CPColor *areaColor = [CPColor colorWithComponentRed:1.0 green:1.0 blue:1.0 alpha:0.6]; CPGradient *areaGradient = [CPGradient gradientWithBeginningColor:areaColor endingColor:[CPColor clearColor]]; areaGradient.angle = -90.0f; CPFill *areaGradientFill = [CPFill fillWithGradient:areaGradient]; dataSourceLinePlot.areaFill = areaGradientFill; dataSourceLinePlot.areaBaseValue = CPDecimalFromString(@"320.0"); // OHLC plot NSLog(@"OHLC Plot"); CPLineStyle *whiteLineStyle = [CPLineStyle lineStyle]; whiteLineStyle.lineColor = [CPColor whiteColor]; whiteLineStyle.lineWidth = 1.0f; CPTradingRangePlot *ohlcPlot = [[[CPTradingRangePlot alloc] initWithFrame:graph.bounds] autorelease]; ohlcPlot.identifier = @"OHLC"; ohlcPlot.lineStyle = whiteLineStyle; ohlcPlot.stickLength = 2.0f; ohlcPlot.plotStyle = CPTradingRangePlotStyleOHLC; ohlcPlot.dataSource = self; NSLog(@"Data source set, adding plot"); [graph addPlot:ohlcPlot]; } And my delegate methods like this: #pragma mark - #pragma mark CPPlotdataSource Methods - (NSUInteger)numberOfRecordsForPlot:(CPPlot *)plot { NSUInteger maxCount = 0; NSLog(@"Getting number of records."); if (self.data1 && [self.data1 count] > maxCount) { maxCount = [self.data1 count]; } if (self.data2 && [self.data2 count] > maxCount) { maxCount = [self.data2 count]; } if (self.data3 && [self.data3 count] > maxCount) { maxCount = [self.data3 count]; } NSLog(@"%u records", maxCount); return maxCount; } - (NSNumber *)numberForPlot:(CPPlot *)plot field:(NSUInteger)fieldEnum recordIndex:(NSUInteger)index { NSLog(@"Getting record @ idx %u", index); return [NSNumber numberWithInt:index]; } All the code above is in the view controller for the view hosting the plot, and when initGraph is called, numDays is 30. I realize of course that this plot, if it even worked, would look nothing like the AAPLot example. The problem I'm having is that the view is never shown. It finished loading because viewDidLoad is the method that calls initGraph above, and the NSLog statements indicate that initGraph finishes. What's strange is that I return a value of 54 from numberOfRecordsForPlot, but the plot asks for more than 54 data points. in fact, it never stops asking. The NSLog statement in numberForPlot:field:recordIndex prints forever, going from 0 to 54 and then looping back around and continuing. What's going on? Why won't the plot stop asking for data and draw itself?

  • UITextField keyboard difference between simulator and real device

    - by Raphael Pinto
    Hi, I am trying get float value with UITextField. On the simulator V3.1.3 in English, I have to use '.' to separate my float values. But on my Iphone 3GS V3.1.3 in French, I have to use ',' to separate them. If I use '.' on my Iphone 3GS, my float is troncated : 3.22222 = 3.0000000 Is there a solution to detect the language version and use the good separator automaticaly?

  • Disable antialiasing for a specific GDI device context

    - by Jacob Stanley
    I'm using a third party library to render an image to a GDI DC and I need to ensure that any text is rendered without any smoothing/antialiasing so that I can convert the image to a predefined palette with indexed colors. The third party library i'm using for rendering doesn't support this and just renders text as per the current windows settings for font rendering. They've also said that it's unlikely they'll add the ability to switch anti-aliasing off any time soon. The best work around I've found so far is to call the third party library in this way (error handling and prior settings checks ommitted for brevity): private static void SetFontSmoothing(bool enabled) { int pv = 0; SystemParametersInfo(Spi.SetFontSmoothing, enabled ? 1 : 0, ref pv, Spif.None); } // snip Graphics graphics = Graphics.FromImage(bitmap) IntPtr deviceContext = graphics.GetHdc(); SetFontSmoothing(false); thirdPartyComponent.Render(deviceContext); SetFontSmoothing(true); This obviously has a horrible effect on the operating system, other applications flicker from cleartype enabled to disabled and back every time I render the image. So the question is, does anyone know how I can alter the font rendering settings for a specific DC? Even if I could just make the changes process or thread specific instead of affecting the whole operating system, that would be a big step forward! (That would give me the option of farming this rendering out to a separate process- the results are written to disk after rendering anyway) EDIT: I'd like to add that I don't mind if the solution is more complex than just a few API calls. I'd even be happy with a solution that involved hooking system dlls if it was only about a days work. EDIT: Background Information The third-party library renders using a palette of about 70 colors. After the image (which is actually a map tile) is rendered to the DC, I convert each pixel from it's 32-bit color back to it's palette index and store the result as an 8bpp greyscale image. This is uploaded to the video card as a texture. During rendering, I re-apply the palette (also stored as a texture) with a pixel shader executing on the video card. This allows me to switch and fade between different palettes instantaneously instead of needing to regenerate all the required tiles. It takes between 10-60 seconds to generate and upload all the tiles for a typical view of the world. EDIT: Renamed GraphicsDevice to Graphics The class GraphicsDevice in the previous version of this question is actually System.Drawing.Graphics. I had renamed it (using GraphicsDevice = ...) because the code in question is in the namespace MyCompany.Graphics and the compiler wasn't able resolve it properly. EDIT: Success! I even managed to port the PatchIat function below to C# with the help of Marshal.GetFunctionPointerForDelegate. The .NET interop team really did a fantastic job! I'm now using the following syntax, where Patch is an extension method on System.Diagnostics.ProcessModule: module.Patch( "Gdi32.dll", "CreateFontIndirectA", (CreateFontIndirectA original) => font => { font->lfQuality = NONANTIALIASED_QUALITY; return original(font); }); private unsafe delegate IntPtr CreateFontIndirectA(LOGFONTA* lplf); private const int NONANTIALIASED_QUALITY = 3; [StructLayout(LayoutKind.Sequential)] private struct LOGFONTA { public int lfHeight; public int lfWidth; public int lfEscapement; public int lfOrientation; public int lfWeight; public byte lfItalic; public byte lfUnderline; public byte lfStrikeOut; public byte lfCharSet; public byte lfOutPrecision; public byte lfClipPrecision; public byte lfQuality; public byte lfPitchAndFamily; public unsafe fixed sbyte lfFaceName [32]; }

  • QT: Scroll widget that renders directly to the DC

    - by shoosh
    I'm trying to create a widget which paints directly to the windows Device Context by calling getDC() and painting an HBITMAP to it. The widget I'm painting resides inside a scroll widget. I've implemented the paintEvent() and it does seem to paint but immediatly after painting the widget gets painted over again with a blank gray color. I've tried setting WA_PaintOnScreen and Qt::WA_NoSystemBackground but none of those help. In theory this should be possible since this is basically how the GLWidget works. What am I missing?

  • Use same project to create multiple applications on same device

    - by Mark.Prof
    I am deploying a reader application with it's document packaged in the asset folder. Any branding is done by dynamically generating xml and resources as appropriate. The application name itself is also generated. Since it is the tag's "package" property that needs to be unique, I nevertheless have a problem installing more than one instance of this app. I would like to dynamically edit the manifest package attribute's value to reflect the document and brand that I am building. But this causes build problems, specifically the location of R.java is no longer available to the component package under which the code resides. Originally, the component package is the same as the application manifest package. But precisely this manifest package name is the part that needs to be variable. How should I best proceed?

  • How to make an existing socket fail?

    - by Huckphin
    OK. So, this is exactly the opposite of what everyone asks about in network programming. Usually, people ask how to make a broken socket work. I, on the other hand am looking for the opposite. I currently have sockets working fine, and want them to break to re-create this problem we are seeing. I am not sure how to go about intentionally making the socket fail by having a bad read. The trick is this: The socket needs to be a working, established connection, and then it must fail for whatever reason. I'm writing this in C and the drivers are running on a Linux system. The sockets are handled by a non-IP Level 3 protocol in Linux by a Linux Device Driver. I have full access to all of the code-base, I just need to find a way to tease it out so that it can fail. Any ideas?

  • What device manufacturers have their own Java ME API's

    - by Andres
    I know that BlackBerry and Nokia provide their own API's that go above and beyond what is specified in MIDP, CLDC, or any of the JSRs for Java ME. I am looking at a few other platforms for Java ME development and needed to know: Do Windows Mobile, LG, Samsung, ZTE, or Huawei provide their own API's for Java ME development?

  • register device at run time

    - by user177893
    In the App ID section of the Program Portal, locate the App ID you wish to use with the Apple Push Notification service. Only App IDs with a specific bundle ID can be used with the APNs. You cannot use a “wild-card” application ID. You must see “Available” under the Apple Push Notification service column to register this App ID and configure a certificate for this App ID. Click the ‘Configure’ link next to your desired App ID. In the Configure App ID page, check the Enable Push Notification Services box and click the Configure button. Clicking this button launches the APNs Assistant, which guides you through the next series of steps that create your App ID specific Client SSL certificate. Download the Client SSL certificate file to your download location. Navigate to that location and double-click the certificate file (which has an extension of cer) to install it in your keychain. When you are finished, click Done in the APNS Assistant. Double-clicking the file launches Keychain Access. Make sure you install the certificate in your login keychain on the computer you are using for provider development. The APNs SSL certificate should be installed on your notification server. When you finish these steps you are returned to the Configure App ID page of the iPhone Dev Center portal. The certificate should be badged with a green circle and the label “Enabled”. To complete the APNs set-up process, you will need to create a new provisioning profile containing your APNs-enabled App ID. IS it posssible to do theses steps through code.

  • RAR Decompress on iPhone Device

    - by DenVog
    Has anyone found a solution to decompressing RAR files on iPhone (not Jailbroken)? It would be great if there was a library similar to libz. I did not find anything official from [URL="http://www.rarlab.com/"]RARlab[/URL]. Anyone successful with integrating [URL="http://wdtz.org/iphone/unrar/"]unRAR[/URL] into their app? The source code appears to be C++? I know that this has been asked before, but I've not seen a solution other than porting unRAR which is beyond me. Would greatly appreciate any information or suggestions. Thank you.

  • C# MDX RenderToSurface, where to reset after device is lost?

    - by Moritz Schöfl
    Hi, I got a problem with the RenderToSurface class. When I resize the Form of my Device, the Draw method is still called, but doesnt throw an Exception, it looks like this: device.Clear(ClearFlags.Target, Color.Red, 0, 0); device.BeginScene(); // here is out commented code device.EndScene(); device.Present(); In another method, I wrote this: renderToSurface.BeginScene(surfaces[currentIndex]); // here is out commented code renderToSurface.EndScene(Filter.None); and this method seems to throw a nullpointer exception when I resize the window; So my question is: - where to reset / restore / handle the renderToSurface class? (i tried it with the DeviceReset event like following - void OnDeviceReset(object sender, EventArgs e) { renderToSurface = new RenderToSurface(Game.Device, Game.ClientSize.Width, Game.ClientSize.Height, Format.A8R8G8B8, true, DepthFormat.D16); } )

  • XCode - Copy sqlite DB from simulator and copy onto device for testing

    - by Neal L
    Hello, I am working on a Core Data app, and have populated the sqlite file in the iPhone Simulator with all of the fixtures/data that I use to test the app. I would like to use that sqlite file as a standardized set of testing data. The devices that I test the app on all have different data sets, and I would like to standardize on the one in the simulator. Is there a way in XCode (3 or 4) to add a step to the build/install process that will copy the sqlite file from the iPhone Simulator and install it over the file on the phone (if one exists)? Thanks, Neal

  • Enable access for assistive device programmatically

    - by Dheeraj
    Hi All, I want to enable Access for assistive devices in System Preferences programmatically. But Problem is that my application is not running as root user and i do not want my application to be as root user and also should not ask for any authentication in between. I want to tap all keyboard events globally. I am using CGEventTapCreate() for the same.In the documentation of CGEventTapCreate() API it is mentioned that, Event taps receive key up and key down events if one of the following conditions is true: The current process is running as the root user. Access for assistive devices is enabled. In Mac OS X v10.4 & later, you can enable this feature using System Preferences, Universal Access panel, Keyboard view. I tried manually by checking the Enable Access for assistive devices from System Preference and it gives me expected output. So is there any way to do the same via program without asking for authentication and also application is not running as root user? Thanks, Dheeraj.

  • Home_path issue with RoR testing locally on mobile device

    - by Amir
    When I use <%= link_to image_tag("foo.png"), home_path %> and display it on my localhost on my iPhone, it's broken. When I inspect on with firebug, the src of the image is http://localhost:3000/images/foo.png thus causing it to break on my iPhone. When I use <img src="/images/foo.png" /> it displays fine on my iPhone. I am pointing to the IP address of my PC running the server of my rails app in Safari. It's loading the text but all the css, JavaScript, and images are missing unless the path is absolute with using the rails default helpers. Is there a way to correct this path issue locally so it's absolute like /images/foo.png instead of http://localhost:3000/images/foo.png. Update CSS file paths are also affected. Instead of just making the path /stylesheets/foo.css, it's http://localhost:3000/stylesheets/foo.css. Update: Solution It's the Facebook plugin changing the asset host to the callback url of my facebook app settings which is currently set to http://localhost:3000/
