  • Trying to force redraw of UITableViewCell

    - by Suresh
    I found this post on Beveled UITableViewCells from http://news.selectstartstudios.com/beveled-uitableviewcells/. I'm using the technique to reduce the width of the cells, and for the most part it works great. However, I have a small problem. Sometimes the cells are not redrawn properly. For example, even though a cell is supposed to be a "middle" cell, it is drawn as a "top" cell: yfrog.com/f1screenshot20100424at100 How can I fix this? I have tried forcing the cell to redraw via [cell setNeedsDisplay], [cell setNeedsLayout], [tableView reloadRowAtIndexPath:withAnimation:], [cell drawrect:], and [tableView drawRect:atIndexPath]. I am out of ideas. Thanks again!

  • Casting and getting values from date picker and time picker in android

    - by Rahul Varma
    Hi , I have a date picker and a time picker in my app. Can anyone tell me how to get the values of the date and time that are selected??? What i mean to say is, for EditText we can declare as final EditText Name = (EditText) this.findViewById(R.id.nametext); and we can cast the data of it by using Name.getText().toString(). So similarly how can we get the values of date picker and time picker to a string???

  • BroadcastReceiver not receiving an alarm's broadcast

    - by juanjux
    I have a code that sets a new repeating alarm (on production I'll use a inexactRepeating), but the BroadCastReceiver I've registered for handling it is not being called. Here is the code where I set the alarm: newAlarmPeriod = 5000; // For debugging Intent alarmIntent = new Intent(this, GroupsCheckAlarmReceiver.class); PendingIntent sender = PendingIntent.getBroadcast(this, Constants.CHECK_ALARM_CODE, alarmIntent, 0); AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE); am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + newAlarmPeriod, newAlarmPeriod, sender); It seems to work and it triggers and alarm every five seconds, as seen in the output of "adb shell dumpsys alarm": DUMP OF SERVICE alarm: Current Alarm Manager state: Realtime wakeup (now=1269941046923): RTC_WAKEUP #1: Alarm{43cbac58 type 0 android} type=0 when=1269997200000 repeatInterval=0 count=0 operation=PendingIntent{43bb1738: PendingIntentRecord{43bb1248 android broadcastIntent}} RTC_WAKEUP #0: Alarm{43ce30e0 type 0 com.almarsoft.GroundhogReader} type=0 when=1269941049555 repeatInterval=5000 count=1 operation=PendingIntent{43d990c8: PendingIntentRecord{43d49108 com.almarsoft.GroundhogReader broadcastIntent}} RTC #1: Alarm{43bfc250 type 1 android} type=1 when=1269993600000 repeatInterval=0 count=0 operation=PendingIntent{43c5a618: PendingIntentRecord{43c4f048 android broadcastIntent}} RTC #0: Alarm{43d67dd8 type 1 android} type=1 when=1269941100000 repeatInterval=0 count=0 operation=PendingIntent{43c4e0f0: PendingIntentRecord{43c4f6c8 android broadcastIntent}} Broadcast ref count: 0 Alarm Stats: android 24390ms running, 0 wakeups 80 alarms: act=android.intent.action.TIME_TICK flg=0x40000004 com.almarsoft.GroundhogReader 26ms running, 2 wakeups 2 alarms: flg=0x4 cmp=com.almarsoft.GroundhogReader/.GroupsCheckAlarmReceiver But for some reason my BroadCastReceiver is not being called when the alarm is triggered. I've declared it on the Manifest: <receiver android:name=".GroupsCheckAlarmReceiver" /> And this is the abbreviated code: public class GroupsCheckAlarmReceiver extends BroadcastReceiver{ @Override public void onReceive(Context context, Intent intent) { Toast.makeText(context, "XXX Alarm worked.", Toast.LENGTH_LONG).show(); Log.d("XXX", "GroupsCheckAlarmReceiver.onReceive"); }

  • CATiledLayer blanking tiles before drawing contents

    - by Greg Plesur
    All, I'm having trouble getting behavior that I want from CATiledLayer. Is there a way that I can trigger the tiles to redraw without having the side-effect that their areas are cleared to white first? I've already subclassed CATiledLayer to set fadeDuration to return 0. To be more specific, here are the details of what I'm seeing and what I'm trying to achieve: I have a UIScrollView with a big content size...~12000x800. Its content view is a UIView backed by a CATiledLayer. The UIView is rendered with a lot of custom-drawn lines Everything works fine, but the contents of the UIView sometimes change. When that happens, I'd like to redraw the tiles as seamlessly as possible. When I use setNeedsDisplay on the view, the tiles redraw but they are first cleared to white and there's a fraction-of-a-second delay before the new content is drawn. I've already subclassed CATiledLayer so that fadeDuration is set to 0. The behavior that I want seems like it should be possible...when you zoom in on the scrollview and the content gets redrawn at a higher resolution, there's no blanking before the redraw; the new content is drawn right on top of the old one. That's what I'm looking for. Thanks; I appreciate your ideas. Update: Just to follow up - I realized that the tiles weren't being cleared to white before the redraw, they're being taken out entirely; the white that I was seeing is the color of the view that's beneath my CATiledLayer-backed view. As a quick hack/fix, I put a UIImageView beneath the UIScrollView, and before triggering a redraw of the CATiledLayer-backed view I render its visible section into the UIImageView and let it show. This smooths out the redraw significantly. If anyone has a better solution, like keeping the redraw-targeted tiles from going away before being redrawn in the first place, I'd still love to hear it.

  • Removing Divider Line from UISplitViewController

    - by tilomitra
    Guys, I know a similar question exists but the thread seems to be inactive, and I really would like this question to be answered. It's been annoying me for a few days now. I'm wondering how to remove the divider line between the Master and Detail view in the UISplitViewController. I know its possible to remove/hide/cover it up because I see some apps in the store without that line. I have tried setting backgroundColor to clearColour on my views but to no avail. So SO community, you're my only hope!

  • iPhone backup & restore does not restore our app's data on rare occasions

    - by Michael Waterfall
    We have an iPhone app with several thousand users, and we've had one or two users saying that after a full backup & restore procedure within iTunes, the data for our app was lost. All the data (photos & SQLite DB) are stored in the documents area of the app. I've tested this thoroughly with our devices and it works absolutely fine. Can anyone think of a reason for this, or has anyone experienced this before?

  • Packaging a Bundle with a static library

    - by 4thSpace
    I have a static library that includes some xibs. These will basically be the same across projects. I'd like to include the xibs as part of the library. I can include their veiwcontrollers, reference these controllers in the calling project but then there isn't a xib to load. When I right click the xib in the library project, it can't be part of the target. I thought about creating a CFPluginBundle but that creates a new project. I'd loose all of my IBOutlet and IBAction references. What is the best way to reuse xibs that also have outlets and actions to specific controllers?

  • What's the UITableView index magnifying glass character?

    - by David Grant
    In Apple's iPhone apps (like Contacts), they have a nice magnifying glass icon at the top of the table view index. Since the table view index API is character-based, I assume that this magnifying glass is a Unicode character. So far I've resorted to placing a question mark character there, but that looks lame. Can anyone tell me what character the magnifying glass is?

  • touchesEnded not being called??? or randomly being called

    - by Rob
    If I lift my finger up off the first touch, then it will recognize the next touch just fine. It's only when I hold my first touch down continuously and then try and touch a different area with a different finger at the same time. It will then incorrectly register that second touch as being from the first touch again. Update It has something to do with touchesEnded not being called until the very LAST touch has ended (it doesn't care if you already had 5 other touches end before you finally let go of the last one... it calls them all to end once the very last touch ends) - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch* touch = [touches anyObject]; NSString* filename = [listOfStuff objectAtIndex:[touch view].tag]; // do something with the filename now } - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { ITouch* touch = [touches anyObject]; NSString* buttonPressed = [listOfStuff objectAtIndex:[touch view].tag]; // do something with this info now }

  • Why are my "tel:" links not working

    - by Griffo
    I have a tableView which has cells with phone numbers. The app is not dialing the numbers though. See the code below - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if (indexPath.section == 2) { UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath]; NSString *numberToDial = [NSString stringWithFormat:@"tel:%@", selectedCell.detailTextLabel.text]; NSLog(@"%@",numberToDial); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:numberToDial]]; } } Console ouput: 2010-03-08 01:32:30.830 AIB[1217:207] tel:01 8350098 As you can see, the number goes to the console, but doesn't get dialled. The weird thing is, if I change the last statement to this: [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:171"]]; the phone dials the number 171 without any issue

  • mkmapview userlocation annimation issue

    - by Gedeon
    I have issue with userlocation in mkmapview. The thing is that i have navigation controller which pushes mapview , as soon as it pushes it userlocation is queried. But if user pop mapview view before userlocation animation is finished , it throws exception because animation is trying to access deallocated mapview instance. So my question is , how to prevent that. I could do it by disabling back button , but i am not sure if that right way to take. Does anybody know how to stop current animation?

  • How do I create a UISplitView manually?

    - by Mark
    I have an app that is going to navigate to a UISplitView (inside another view altogether) like so: - (void) switchToMyDayView { NSLog(@"Show My Day Screen"); if (self.myDayController.view.superview == nil) { if (self.myDayController == nil) { MyDayController *myController = [[MyDayController alloc] initWithNibName:@"MyDay" bundle:nil]; self.myDayController = myController; [myController release]; } [homeScreenController.view removeFromSuperview]; [self.view insertSubview:self.myDayController.view atIndex:0]; } } Which is done on the main navigation screen Now, the MyDayController has a XIB called MyDay.xib which has these items: File's Owner: MyDayController First Responder: UIResponder Split View Controller ---->Navigation Controller ---->Navigation Bar ----> Table View Controller ----> Navigation Item ---->View Controller So, I need some more components here, I need a UITableViewController and a UISplitViewControllerDelegate correct? I was going to just implement these protocols in my MyDayController, is this sort of standard? So, after the code above, I get an error: -[UIViewController _loadViewFromNibNamed:bundle:] loaded the "MyDay" nib but the view outlet was not set. so, how can I fix it using the UISplitViewController? I know that the UISplitViewController has a view property, but I cannot use it/connect it up in IB can I? Thanks a lot Mark

  • UITableViewCellStyleValue2 edit indicators?

    - by Jason Jardim
    I am using this style of table view UITableViewCellStyleValue2. I set editing, but I cant seem to get the arrows to show up on the right of the cell - like the Contacts app. Also in the contacts app I notice that if I have a Favorite it puts a * (star) to the right. Any info on how to get an image would be appreciated. Thanks!

  • Android customizing ViewFlipper...

    - by wearysamurai
    So I'm having pretty much exactly the problem described here: http://code.google.com/p/android/issues/detail?id=6191 and until the ViewFlipper issue in 2.1 and 2.2 has been resolved, I'm attempting to customize my own ViewFlipper in the manner described: @Override protected void onDetachedFromWindow() { try { super.onDetachedFromWindow(); } catch (IllegalArgumentException e) { // Call stopFlipping() in order to kick off updateRunning() stopFlipping(); } } But I've never done this sort of thing before and am hoping to get a little guidance (as my own efforts are coming up short). Here's what I have so far. FixedFlipper.java: import android.content.Context; import android.util.AttributeSet; import android.widget.ViewFlipper; public class FixedFlipper extends ViewFlipper{ public FixedFlipper(Context context){ super(context); } public FixedFlipper(Context context, AttributeSet attrs){ super(context, attrs); } @Override protected void onDetachedFromWindow(){ try{ super.onDetachedFromWindow(); }catch(Exception e){ super.stopFlipping(); } } } main.xml: <com.site.TestApp.FixedFlipper style="@style/body" android:id="@+id/flipper"> ... </com.site.TestApp.FixedFlipper> And in my activity, I invoke it like so: FixedFlipper flipper = (FixedFlipper)findViewById(R.id.flipper); It seems like it should be pretty straightforward, but I keep getting this: Binary XML file line #4: Error inflating class com.site.TestApp.FixedFlipper I appreciate any suggestions. I've been chasing my tail for hours trying to figure out what piece of the puzzle I'm missing.

  • Downloading file with ASIHTTPRequest - iPhone app

    - by lostInTransit
    Hi I am using the ASIHTTPRequest source code to download a file from a remote location. Surprisingly, the download happens but nothing happens after that. I have put in a log statement in the handleBytesAvailable method and can see the entire file worth of data is downloaded in parts and added to the fileDownloadOutputStream variable. But once all the bytes have been downloaded, nothing happens. The delegate methods are not called (neither fail, nor success). Can someone please tell me what is happening? Or what is the correct way to download a file from a remote server using ASIHTTPRequest? Thanks.

  • Stop Progressbar manual scrolling in Android

    - by Rony
    Hi experts, I have already posted my query here, but unfortunately, not getting the required support for this simple query. http://www.anddev.org/prevent_manual_moving_of_seekbar_widget-t13048.html I am using progressbar widget in my application to show the download progress. In the current state, I am able to manually move the slider back and forth while download is progressing. How can I prevent the manual moving of progressbar, instead it works only based on progressbar.setProgress(progressbar.getProgress() + 1024); -- currently this works perfect, but I need to prevent the manual moving of progressbar during download. Any help in this regard is appreciated. Regards, Rony
