  • How to check a local wifi connection

    - by Thomas Joos
    hi all, I'm writing an app which connects to a static ip adress in a local network. How can I check if I have a local network connection? I want to connect to http://192.168.2.5 and i tried using the Rechability class but it returns FALSE, while the device is definately connected ( when i don't do the check, the app works fine so there is a connection ): Reachability *r = [Reachability reachabilityWithHostName:@"http://192.168.2.5"]; NetworkStatus internetStatus = [r currentReachabilityStatus]; How should work this out?

  • Optimizing drawing on UITableViewCell

    - by Brian
    I am drawing content to a UITableViewCell and it is working well, but I'm trying to understand if there is a better way of doing this. Each cell has the following components: Thumbnail on the left side - could come from server so it is loaded async Title String - variable length so each cell could be different height Timestamp String Gradient background - the gradient goes from the top of the cell to the bottom and is semi-transparent so that background colors shine through with a gloss It currently works well. The drawing occurs as follows: UITableViewController inits/reuses a cell, sets needed data, and calls [cell setNeedsDisplay] The cell has a CALayer for the thumbnail - thumbnailLayer In the cell's drawRect it draws the gradient background and the two strings The cell's drawRect it then calls setIcon - which gets the thumbnail and sets the image as the contents of the thumbnailLayer. If the image is not found locally, it sets a loading image as the contents of the thumbnailLayer and asynchronously gets the thumbnail. Once the thumbnail is received, it is reset by calling setIcon again & resets the thumbnailLayer.contents This all currently works, but using Instruments I see that the thumbnail is compositing with the gradient. I have tried the following to fix this: setting the cell's backgroundView to a view whose drawRect would draw the gradient so that the cell's drawRect could draw the thumbnail and using setNeedsDisplayInRect would allow me to only redraw the thumbnail after it loaded --- but this resulted in the backgroundView's drawing (gradient) covering the cell's drawing (text). I would just draw the thumbnail in the cell's drawRect, but when setNeedsDisplay is called, drawRect will just overlap another image and the loading image may show through. I would clear the rect, but then I would have to redraw the gradient. I would try to draw the gradient in a CAGradientLayer and store a reference to it, so I can quickly redraw it, but I figured I'd have to redraw the gradient if the cell's height changes. Any ideas? I'm sure I'm missing something so any help would be great.

  • Setting up gcov in Xcode 3.1

    - by Algorithmic
    I'm trying to setup my Xcode project to be instrumented with gcov so I can determine the code coverage of my unit tests. All of the documentation I find online talks about settings that I don't find in Xcode 3.1, though. An example: To work with Coverstory, first you need to set up your target to work with gcov. This requires turning on "Instrument Program Flow", "Generate Test Coverage Files" and linking with the gcov library. (Using Coverstory) The closest thing I can find to "Instrument Program Flow" and "Generate Test Coverage Files" in my build settings is "Generate Profiling Code", which doesn't appear to do what I want it to do. Am I looking in the wrong place for these settings or are all of the examples I'm finding online stale?

Lets say I have 2 locations- the devices current location, and a location of some restaurant for example- I would like to detect when the device is heading towards that restaurant. (I asked this before with no answers- I thought maybe if I'll rephrase the question...) Thanks.

  • Set tag and hidden for objects on custom UITableViewCell

    - by Rob
    I am re-using Apple's AdvancedTableViewCells example to create a custom, fast-scrolling tableview. Specifically, I am using their CompositeSubviewBasedApplicationCell method which draws the content on the tableviewcell with drawRect Everything works, but how do you hide a label or set the tag for a label or image using their method? Doing it this way is pretty new to me (without IB), so I apologize ahead of time if it's something easy. The code that sets the cell content is: - (void)drawRect:(CGRect)rect { [_cell.animalIcon drawAtPoint:CGPointMake(5.0, 5.0)]; [_cell.animalName drawAtPoint:CGPointMake(93.0, 25.0)]; _highlighted ? [[UIColor whiteColor] set] : [[UIColor colorWithWhite:0.23 alpha:1.0] set]; [_cell.animalDescription drawAtPoint:CGPointMake(100.0, 54.0) withFont:[UIFont boldSystemFontOfSize:13.0]]; [_cell.animalNameString drawAtPoint:CGPointMake(93.0, 5.0) withFont:[UIFont boldSystemFontOfSize:13.0]]; }

  • How can I click a button behind a transparent UIView?

    - by Sean Clark Hess
    Let's say we have a view controller with one sub view. the subview takes up the center of the screen with 100 px margins on all sides. We then add a bunch of little stuff to click on inside that subview. We are only using the subview to take advantage of the new frame ( x=0, y=0 inside the subview is actually 100,100 in the parent view). Then, imagine that we have something behind the subview, like a menu. I want the user to be able to select any of the "little stuff" in the subview, but if there is nothing there, I want touches to pass through it (since the background is clear anyway) to the buttons behind it. How can I do this? It looks like touchesBegan goes through, but buttons don't work.

  • Linking to non-home panel in JQTouch site

    - by Patrick Dinnen
    I'm trying to create a link from an external site that arrives at a particular, internal panel on a JQTouch site I'm building. However the browser always opens the home panel of the JQT site no matter what anchor tag I use in the link. e.g. If I try to link to the User Interface panel in the official JQTouch demo I use http://www.jqtouch.com/preview/demos/main/#ui but the home panel shows in the browser and not the sub-panel I requested. Any suggestions would be very welcome. I have control of the both the linked and linking sites so can tweak code is necessary. Thanks

  • Android interacting with HTML5 tutorial?

    - by Adam
    I've been looking at using a WebView to display an HTML5 webpage, where the novel features of the mobile device (GPS, compass, accelerometer, camera, etc) can be fed back into the web page. I was wondering if there were any good tutorials showing these functions interacting with the webview. So far I've found ways for the WebView to send javascript commands to the web page, but those interactions haven't been triggered from outside the web view (such as upon receiving an intent from the GPS or accelerometer). Note: The HTML5 Geolocation API is not what I'm interested in. I'm interested in the web page <- WebView interactions, as noted here: http://android-developers.blogspot.com/2008/09/using-webviews.html

  • _resignRootViewController causes app to crash.

    - by RickiG
    [MainViewController _resignRootViewController]: message sent to deallocated instance 0x4ebfe50 This error happens when I try to pop my MainViewController Object from within it self: - (void) switchToTableView { //a method on the MainViewController [self.navigationController popViewControllerAnimated:NO]; [[UIApplication applicationDelegate] switchToTableView]; //convenience method for the app delegate } The debugger stops at the [super dealloc] command in MainViewControllers dealloc method. I do the exact same thing in the TripTableViewController, but here it never crashes. MainViewController and TripTableViewController are handled in my AppDelegate like this: - (void) switchToTableView { TripTableViewController *tripTableViewController = [[TripTableViewController alloc] init]; [[self.navigationController navigationBar] setHidden:NO]; [self.navigationController pushViewController:tripTableViewController animated:NO]; [tripTableViewController release]; } - (void) switchToScrollView { MainViewController *scrollView = [[MainViewController alloc] init]; [[self.navigationController navigationBar] setHidden:YES]; [self.navigationController pushViewController:scrollView animated:NO]; [scrollView release]; } I am trying to achieve that when the user goes from TripTableViewController to MainViewController; TripTableViewController is released/popped and visa versa for the MainViewController. I do not wish for the navigationController to make the decision about when to pop/cache/release them, this is why I try to do it from within it self. I have not been able to find the _resignRootViewController mentioned anywhere. My guess is that it is a delegate message sent by a ViewController that resigns as rootViewController for a navigationController and that somehow it is called twice, once before MainViewCOntroller is released/popped and somehow again afterwards. Have any one else seen this error message before? Google and the Apple Docs does not mention it? How can I debug such an error? Hope someone can guide me in the right direction on this one, Thanks:)

  • How do I remove those rotation artefacts from my CATiledLayer?

    - by Felix
    Hello all, I have a CATiledLayer into which I render content in the following method - (void)drawLayer:(CALayer *)layer inContext:(CGContextRef)ctx I used the QuartzDemo code to draw a pattern. This works very well until I apply a rotation transform to the layer's parentLayer (a UIView): rotated: These zigzag artefacts become worse when I start drawing lines and texts into the CATiledLayer. I applied the transform as follows (I also tried using an affine transform on the view itself): self.containerView.layer.transform = CATransform3DMakeRotation(angleRadians, 0.0f, 0.0f, 1.0f); I transform the containerView rather than the layer itself, as I have several layers in that view that I would like to rotate at the same time without changing the relative positions. I did not have problems when rotating UIImageViews in the past. Is there a way that I can rotate the CATiledLayer without these problems? Any help would be greatly appreciated. Yours, Felix

  • Making complex queries through SQLiteDatabase

    - by Luca
    Hi! I'm using the Android MediaProvider application to get information regarding the resources registered in the media library. The only way I found to do this is to use the ContentProvider class provided by the MediaProvider application. Unfortunately, it seems to me this is quite a limitation, isn't it? Is it possible this way to create complex queries with subqueries and using other functions of SQLite? I thought that it may be possible using the SQLiteDatabase class, but it seems it is not possible to open the database directly with its path, and anyway, the query method seems not to allow subqueries. Any solution to this? Thanks!

  • Problem Showing Sensors Details

    - by Skatephone
    Hi, i'm looking to show detail about sensors in an Actvity but when i put my app in to my phone i manage to view only details about the accellerometer, but the program says that i have 4 sensors: Accellerometer, Magnetic field, Orientation and Temperature. I'm using Android 1.6 and a htc Tattoo for testing. This is my code: public class SensorInfo extends Activity { private SensorManager mSensorManager; TextView mTextAcc,mTextGyr,mTextLig,mTextMag,mTextOri, mTextPre,mTextPro,mTextTem, mSensorsTotTitle,mSensorAvailablesTitle,mTextAccTitle,mTextGyrTitle,mTextLigTitle,mTextMagTitle,mTextOriTitle, mTextPreTitle,mTextProTitle,mTextTemTitle; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.detaillayout); // Get the texts fields of the layout and setup to invisible setTextViews(); // Get the SensorManager mSensorManager= (SensorManager) getSystemService(SENSOR_SERVICE); // List of Sensors Available List<Sensor> msensorList = mSensorManager.getSensorList(Sensor.TYPE_ALL); // Print Sensor Details Sensor sens; int type,i; String text = new String(""); // Do the list of available sensors on a String and print detail about each sensor for (i=0;i<msensorList.size();i++){ sens = msensorList.get(i); type = sens.getType(); text = " - "+getString(R.string.power)+" "+String.valueOf(sens.getPower())+"mA\n"; text+= " - "+getString(R.string.resolution)+" "+String.valueOf(sens.getResolution())+"\n"; text+= " - "+getString(R.string.maxrange)+" "+String.valueOf(sens.getMaximumRange ())+"\n"; text+= " - "+getString(R.string.vendor)+" "+sens.getVendor()+"\n"; text+= " - "+getString(R.string.version)+" "+String.valueOf(sens.getVersion()); switch(type) { // Check the type of Sensor that generate the event and show is resolution case Sensor.TYPE_ACCELEROMETER: mTextAccTitle.setVisibility(0); mTextAccTitle.setMaxHeight(30); mTextAcc.setVisibility(0); mTextAcc.setMaxHeight(100); mTextAcc.setText(text); // Print data of the Sensor break; case Sensor.TYPE_GYROSCOPE: mTextGyrTitle.setVisibility(0); mTextGyr.setVisibility(0); mTextGyr.setText(text); // Print data of the Sensor break; case Sensor.TYPE_LIGHT: mTextLigTitle.setVisibility(0); mTextLig.setVisibility(0); mTextLig.setText(text); // Print data of the Sensor break; case Sensor.TYPE_MAGNETIC_FIELD: mTextMagTitle.setVisibility(0); mTextMag.setVisibility(0); mTextMag.setText(text); // Print data of the Sensor break; case Sensor.TYPE_ORIENTATION: mTextOriTitle.setVisibility(0); mTextOri.setVisibility(0); mTextOri.setText(text); // Print data of the Sensor break; case Sensor.TYPE_PRESSURE: mTextPreTitle.setVisibility(0); mTextPre.setVisibility(0); mTextPre.setText(text); // Print data of the Sensor break; case Sensor.TYPE_PROXIMITY: mTextProTitle.setVisibility(0); mTextPro.setVisibility(0); mTextPro.setText(text); // Print data of the Sensor break; case Sensor.TYPE_TEMPERATURE: mTextTemTitle.setVisibility(0); mTextTem.setVisibility(0); mTextTem.setText(text); // Print data of the Sensor break; } } } // Get the texts fields of the layout and setup to invisible void setTextViews(){ mTextAccTitle = (TextView) findViewById(R.id.sensorAccTitle); mTextAccTitle.setVisibility(4); mTextAccTitle.setMaxHeight(0); mTextAcc = (TextView) findViewById(R.id.sensorAcc); mTextAcc.setMaxHeight(0); mTextAcc.setVisibility(4); mTextGyrTitle = (TextView) findViewById(R.id.sensorGyrTitle); mTextGyrTitle.setVisibility(4); mTextGyrTitle.setMaxHeight(0); mTextGyr = (TextView) findViewById(R.id.sensorGyr); mTextGyr.setVisibility(4); mTextGyrTitle.setMaxHeight(0); mTextLigTitle = (TextView) findViewById(R.id.sensorLigTitle); mTextLigTitle.setVisibility(4); mTextLigTitle.setMaxHeight(0); mTextLig = (TextView) findViewById(R.id.sensorLig); mTextLig.setVisibility(4); mTextLig.setMaxHeight(0); mTextMagTitle = (TextView) findViewById(R.id.sensorMagTitle); mTextMagTitle.setVisibility(4); mTextMagTitle.setMaxHeight(0); mTextMag = (TextView) findViewById(R.id.sensorMag); mTextMag.setVisibility(4); mTextMag.setMaxHeight(0); mTextOriTitle = (TextView) findViewById(R.id.sensorOriTitle); mTextOriTitle.setVisibility(4); mTextOriTitle.setMaxHeight(0); mTextOri = (TextView) findViewById(R.id.sensorOri); mTextOri.setVisibility(4); mTextOri.setMaxHeight(0); mTextPreTitle = (TextView) findViewById(R.id.sensorPreTitle); mTextPreTitle.setVisibility(4); mTextPreTitle.setMaxHeight(0); mTextPre = (TextView) findViewById(R.id.sensorPre); mTextPre.setVisibility(4); mTextPre.setMaxHeight(0); mTextProTitle = (TextView) findViewById(R.id.sensorProTitle); mTextProTitle.setVisibility(4); mTextProTitle.setMaxHeight(0); mTextPro = (TextView) findViewById(R.id.sensorPro); mTextPro.setVisibility(4); mTextPro.setMaxHeight(0); mTextTemTitle = (TextView) findViewById(R.id.sensorTemTitle); mTextTemTitle.setVisibility(4); mTextTemTitle.setMaxHeight(0); mTextTem = (TextView) findViewById(R.id.sensorTem); mTextTem.setVisibility(4); mTextTem.setMaxHeight(0); } } Tank's Valerio From Italy
