  • Personalized UIView created with Interface Builder

    - by Malox
    I need to project a personalized UIView with a UIImageView and 3 UILabel. I need to allocate more of this view because I want put it into a UIScrollView. I would avoid to generate the view programatically because it's difficult and boring design it. My idea is to create a new class that extends UIView and design it with interface builder. For example my Personalized View code is like that: #import <UIKit/UIKit.h> @interface PersonalizedPreview : UIView { IBOutlet UIImageView *image; IBOutlet UILabel *first_label; IBOutlet UILabel *second_label; IBOutlet UILabel *third_label; } -(void) setImage:(UIImage *)image; @property (nonatomic, retain) IBOutlet UIImageView *image; @property (nonatomic, retain) IBOutlet UILabel *label; .... @end I would create an associated xib file for this view and initialize it simply specifing the xib file. Note that I don't want create a specific ViewController for this view and PersonalizedView is instantiate at runtime not when the app runs, moreover I don't know how many PersonalizedView I will instantiate, it depends on runtime execution. Anyone can help me? Thank you very much.

  • iPhone: App crashes when I click on a cell in table view.

    - by Jack Griffiths
    Hi there, Compiling my application works—everything is fine. The only errors I get are by deprecated functions (setText). The only problem is now, is that when I tap on a cell in my table, the app crashes, even though it's meant to push to the next view in the stack. Any solutions are appreciated, if you need any code, just ask. Also, how can I only make sure that one cell goes to only one view? For example: When I tap on CSS, it takes me to a new table with different levels of CSS. WHen I tap on an item in that new view, it comes up with an article on what I just selected. Regards, Jack

  • How to save objects using Multi-Threading in Core Data?

    - by Konstantin
    I'm getting some data from the web service and saving it in the core data. This workflow looks like this: get xml feed go over every item in that feed, create a new ManagedObject for every feed item download some big binary data for every item and save it into ManagedObject call [managedObjectContext save:] Now, the problem is of course the performance - everything runs on the main thread. I'd like to re-factor as much as possible to another thread, but I'm not sure where I should start. Is it OK to put everything (1-4) to the separate thread?

  • Exception when creating an activity: Could not select item Parcel unable to marshal value

    - by user341652
    Hi, I am trying to call an Activity from another instance of the activity. The code is supposed to be a simple file browser (part of a larger application). I am using a ListActivity, and when an item (such as a folder) is selected, it is supposed to open it up in the new Activity. I have a feeling it is a problem with the AndroidManifest (which just has the basic tag). Any assistance would be appreciated. Thanks, Steve

  • Assign click event to addon icon on navigation bar

    - by Charsee
    We have created a chrome extension for our app. Where we call a METHOD from a "js file" on CLICK event of the "extension icon" placed on the navigation bar. For this we use message passing between the app.js (file containing the METHOD to be called on icon click) and background.html (using a js file included in this html). The script used to pass message is:(from background.html) chrome.browserAction.onClicked.addListener(function (tab) { chrome.tabs.sendMessage(tab.id, "showPopup"); }); and to listen the message :(in app.js) chrome.extension.onMessage.addListener(function(request) { if (request === "showPopup") { showPopup(); } }); The click event works as expected. But now we want to do same thing in mozilla extension. and we can't pass message to app.js on the click of the icon,so that it can execute the containing methods. We have also added the app.js using pageMod, something like this exports.main = function(options, callbacks) { pageMod.PageMod({ include: ["*"], contentScriptWhen: 'start', contentScriptFile: [data.url('jquery-1.7.1.min.js'),data.url('app.js')] }); createAndAddNavBarButton(); }; function createAndAddNavBarButton() { var navBar = document.getElementById('nav-bar');//assume document has been defined if (!navBar){return;}; var nbBtn = document.createElement('navbaricon'); nbBtn.setAttribute('id', 'navButton'); nbBtn.setAttribute('image', data.url('icon_16.png')); nbBtn.onclick = function(){ showPopup(); return true; } navBar.appendChild(btn); } But the click event does nothing and showPopup() is undefined. When a new page loads event associated with it in the app.js executes without any error but the click event doesn't work. Is there a method from where we can assign click event directly to this icon, as we have done in the case of chrome extension.

    - by Momeks
    I am using UIWebView as a web browser on my application and when I open an url with my browser and return back to the main view, then go to browser view, my webview doesn't save the content. So, if I go to google.com and switch views, then again go to the browser view, I have to type the url again to open the webpage! How can I save the web browser's content?

  • iPhone - How do I find the MAC address of the connected WiFi access point?

    - by Ciaran
    Without using the private APIs, is it possible to programatically determine the MAC address of the access point that the iPhone is connected to? I understand that this should be doable using the core BSD libraries, but we are new to this, so it would be great if someone can point us to some starter code. Note: we're trying to determine the MAC address of the remote device - not the MAC address of the iPhone.

  • How to get orientation of android from gyrsocope sensor events ?

    - by Pritam
    I am using android 2.3 on Nexus S and want to get orientation from gyroscope sensor events. As gyro gives angular velocity how to use this for getting device orientation ? Also is there any way we can get pure linear accelerations on phone's axis, without gravity vector. I expected this from Linear acceleration sensor event but just found a post and referred android source as well for Sensor which currently uses only accelerometer. So what's the best way to combine the readings from both hardware to get pure accelerations without gravity inclusions ? Thanks.

  • Why would a "view" object in Interface Builder prevent my didFinishLaunchingWithOptions method from

    - by BeachRunnerJoe
    You may have already come across some of my other questions related to question, but I was having an issue with a SplitView iPad app where my application:didFinishLaunchingWithOptions method stopped executing after I went into Interface Builder and changed around the structure of my apps interface. I couldn't figure out what was preventing my didFinishLauchingWithOptions method from executing, but then I removed a "view" object I had in my view heirarchy (shown below) and suddenly my didFinishLauchingWithOptions method started executing again. I've moved passed it now, but I'm still unclear why that would cause the problem. Any ideas why that "view" object would prevent the didFinishLaunchingWithOptions method from executing?

  • awakeFromNib and loadView execute for different instances

    - by Kamchatka
    Hi, I'm trying to understand why: NSLog(@"self = %p", self); in awakeFromNib prints a different value than the same NSLog in viewDidLoad? This isn't a huge problem because I don't need the awakeFromNib but I would like to understand how it works. The code that creates the controller is the following: MyViewController *myViewController = [[MyViewController alloc] initWithNibName:@"MyViewController" bundle:nil]; myViewController.image = tmpImage; [self.navigationController pushViewController:myViewController animated:YES]; [myViewController release]; Thanks for any advices!

  • Cannot play a recorded sound on device.

    - by B_
    I'm using the exact code from the iPhone Application Programming Guide Multimedia Support to use AVAudioRecorder to record a file to the disk and then AVAudioPlayer to load and play that file. This is working fine in the simulator but is not working on the device. The file gets loaded (we can see the NSTimeInterval) but does not play (play returns false). After it didn't work with the sample code from the website, we tried changing to a bunch of different codecs with no success. And of course, the sound is on. Thanks a bunch.

  • Should onSaveInstanceState save the "enabledness" of the views?

    - by neutrino
    Hi there, I have a preferences activity where I can change the language and the theme of my application. From there I return to the previous activity via the Back key, and I want to recreate the activity. I've managed to do that by reinitializing the layout in onResume and also calling onRestoreInstanceState from there. All the views are restored properly, with checkboxes checked if needed, edittexts filled with texts I left there previously. But I also have a button which is initially disabled, and becomes enabled only when a radiobutton is checked. The problem with it is the following: I check the radiobutton, the button becomes enabled. Then I go to settings, change the theme there, and return to the first activity. When I arrive there, the radiobutton is still checked, but the button is disabled. So it seems that the enabled/disabled state isn't being saved into the bundle, which seems counterintuitive. And I haven't found any code in the Android source that does this, too. Am I missing something, or do I have to write my own code for that?

  • How to check whether a CGPoint is inside a UIImageView?

    - by Horace Ho
    In touchesBegan: CGPoint touch_point = [[touches anyObject] locationInView:self.view]; There are tens of UIImageView around, stored in a NSMutableArray images. I'd like to know is there a built-in function to check if a CGPoint (touch_point) is inside one of the images, e.g.: for (UIImageView *image in images) { // how to test if touch_point is tapped on a image? } Thanks Follow up: For unknown reason, pointInside never returns true. Here is the full code. - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { UITouch *touch = [touches anyObject]; touch_point = [touch locationInView:self.view]; for (UIImageView *image in piece_images) { if ([image pointInside:touch_point withEvent:event]) { image.hidden = YES; } else { image.hidden = NO; } NSLog(@"image %.0f %.0f touch %.0f %.0f", image.center.x, image.center.y, touch_point.x, touch_point.y); } } although I can the two points are sometimes identical in the NSLog output ... I also tried: if ([image pointInside:touch_point withEvent:nil]) the result is the same. never returns a true. To eliminate the chance of anything goes with with the images. I tried the following: if (YES or [image pointInside:touch_point withEvent:event]) all images are hidden ater the first click on screen.
