  • iPhone SDK: Transparent tableviewcell isn't transparent?

    - by Harkonian
    I have a UITableViewController that has a background image. I am setting the image for the tableview like this: [self.view setBackgroundColor: [UIColor colorWithPatternImage: [UIImage imageWithContentsOfFile: [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent: @"background1.jpg"]]]]; The problem is, each of my custom tableview cells get the same background image--it's repeated in each cell. As a test, I tried making everything in my cell transparent with an alpha of 0.0, but even then although I can't see any of the labels in each cell, I still see the background image repeated in each cell: cell.backgroundColor = [UIColor clearColor]; cell.contentView.backgroundColor = [UIColor clearColor]; cell.contentView.alpha = 0.0; cell.alpha = 0.0; Any suggestions on how to get my table's background image to stop repeating in each cell would be appreciated!

  • UITabBarController rotation problem with popViewControllerAnimated and selectedIndex (iPhone SDK)

    - by rjobidon
    Hi! This is a very important auto rotate issue and easy to reproduce. My application has a UITabBarController. Each tab is a UINavigationController. Auto rotation is handled with normal calls to shouldAutorotateToInterfaceOrientation and didRotateFromInterfaceOrientation. The interface rotates normally until I call UIViewController.popViewControllerAnimated and change UITabBarController.selectedIndex. Steps to reproduce: Create a demo Tab Bar Application. Add the following code to the App Delegate .h file: #import <UIKit/UIKit.h> @interface TestRotationAppDelegate : NSObject { UIWindow *window; UITabBarController *tabBarController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UITabBarController *tabBarController; -(void)doAction; @end // Redefine the interface to cach rotation messages @interface UITabBarController (TestRotation1AppDelegate) @end Add the following code to the App Delegate .m file: #import "TestRotationAppDelegate.h" @implementation TestRotationAppDelegate @synthesize window; @synthesize tabBarController; -(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [window addSubview:tabBarController.view]; [window makeKeyAndVisible]; return YES; } -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } -(void)dealloc { [tabBarController release]; [window release]; [super dealloc]; } @end @implementation UITabBarController (TestRotation1AppDelegate) -(void)viewDidLoad { [super viewDidLoad]; // Add a third tab and push a view UIViewController *view1 = [[UIViewController alloc] init]; view1.title = @"Third"; UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:view1]; NSMutableArray *array = [[NSMutableArray alloc] init]; [array addObjectsFromArray:self.viewControllers]; [array addObject:nav]; self.viewControllers = array; // Push view2 inside the third tab UIViewController *view2 = [[UIViewController alloc] init]; [nav pushViewController:view2 animated:YES]; // Create a button to pop view2 UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect]; button.frame = CGRectMake(50, 50, 220, 38); [button setTitle:@"Pop this view" forState:UIControlStateNormal]; [button addTarget:self action:@selector(doAction) forControlEvents:UIControlEventTouchUpInside]; [view2.view addSubview:button]; } -(void) doAction { // ROTATION PROBLEM BEGINS HERE // Remove one line of code and the problem doesn't occur. [self.selectedViewController popViewControllerAnimated:YES]; self.selectedIndex = 0; } -(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } @end The interface auto rotates normally until you tap the button on tab #3. Your help will be geatly appreciated!

  • iPhone SDK can't get UIScrollView to work with a UIWebView

    - by Maxwell Segal
    I am building an app that in part of it has two views - one portrait and one landscape. And I want to offer scrolling and pinch & zooming on the landscape orientation. I've built the two views and the simple UIImages in the landscape view all work OK but it does not seem to insert my UIWebView into the UIScrollView. I've done this before with UIImage and all was OK but I must be missing something here - can anybody help with some advice. I'm sure it's something very simple - perhaps to do with the adding of the subview??. Thanks in advance of your help. I've shown the relevant parts of my code below: @interface MonthViewController : UIViewController <UIScrollViewDelegate> { MonthViewController *monthController; IBOutlet UIView *portraitView; IBOutlet UIView *landscapeView; IBOutlet UIWebView *monthKWHChartPortrait; UIWebView *monthKWHChartLandscape; IBOutlet UIScrollView *scrollChartLandscape; IBOutlet UIImageView *eLogoPortrait; IBOutlet UIImageView *eLogoLandscape; IBOutlet UIImageView *clientLogoPortrait; IBOutlet UIImageView *clientLogoLandscape; IBOutlet UIActivityIndicatorView *loadIndicatorPortrait; IBOutlet UIActivityIndicatorView *loadIndicatorLandscape; NSTimer *timer; IBOutlet UILabel *test; } -(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollChartLandscape { return monthKWHChartLandscape; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight); } -(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration { [super willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:duration]; if (toInterfaceOrientation ==UIInterfaceOrientationLandscapeRight) { NSLog(@"right"); test.text=@"right"; NSString *urlAddressLandscape = @"http://PRIVATEURLHERE.aspx?WIDTH=440"; NSURL *urlLandscape = [NSURL URLWithString:urlAddressLandscape]; NSURLRequest *requestObjLandscape = [NSURLRequest requestWithURL:urlLandscape]; [self.monthKWHChartLandscape loadRequest:requestObjLandscape]; scrollChartLandscape.contentSize = CGSizeMake(monthKWHChartLandscape.frame.size.width, monthKWHChartLandscape.frame.size.height); scrollChartLandscape.maximumZoomScale = 2.5; scrollChartLandscape.minimumZoomScale = 0.6; scrollChartLandscape.showsHorizontalScrollIndicator = YES; scrollChartLandscape.showsVerticalScrollIndicator = YES; scrollChartLandscape.clipsToBounds = YES; scrollChartLandscape.delegate = self; [self.scrollChartLandscape addSubview:monthKWHChartLandscape]; self.view=landscapeView; //self.view.transform=CGAffineTransformMakeRotation(deg2rad*(90)); //self.view.bounds=CGRectMake(0.0, 0.0, 480.0, 320.0); } else

  • iPhone SDK - (void)viewDidLoad { } - Show Progress

    - by Hank Brekke
    I have a long - (void)viewDidLoad { } function that uses the internet to load a page, and whenever the application loads the URL, the screen is black. I have a UIActivityIndicator setup to show that the address is loading, but I don't know how to prevent it from seeming as if the application is not responding, and I don't want to show the network activity indicator [[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES]; because the screen will still be black, just with a loader in the top corner. My code is below: - (void)viewDidLoad { NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; email.text = [defaults objectForKey:@"mom_email"]; pass.text = [defaults objectForKey:@"mom_pass"]; if (email.text != nil && pass.text != nil) { [self login:loginBtn]; } } - (IBAction)login:(id)sender { [email resignFirstResponder]; [pass resignFirstResponder]; [loader startAnimating]; // Does nothing though NSString *em = (NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)email.text,NULL,(CFStringRef)@"!*'();:@&=+$,/?%#[]",kCFStringEncodingUTF8); NSString *ps = (NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,(CFStringRef)pass.text,NULL,(CFStringRef)@"!*'();:@&=+$,/?%#[]",kCFStringEncodingUTF8); NSURL *url = [[NSURL alloc] initWithScheme:@"http" host:@"localhost" path:[[NSString alloc] initWithFormat:@"/app/login.php?email=%@&pass=%@", em, ps]]; NSURLRequest *request = [NSURLRequest requestWithURL:url]; NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSString *loginResult = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding]; [loader stopAnimating]; NSRange range = [loginResult rangeOfString:@"1"]; if (range.location != NSNotFound) { [self dismissModalViewControllerAnimated:YES]; // Doesn't do anything if function called from viewDidLoad } }

  • MediaWiki styling for iPhone

    - by Brian Ashe
    When you visit en.wikipedia.org with an iPhone you are forwarded to en.m.wikipedia.org which is formatted beautifully for the device. I have MediaWiki on my own server and I'd love to have this formatting available when I visit my site with my iPhone. Is there an easy way to enable this? I've gotten as far as www.mediawiki.org/wiki/Manual:$wgHandheldForIPhone and http://www.mediawiki.org/wiki/Extension:MobileSkin but nothing is jumping out at me.

  • iPhone SDK: Memory leak on picker

    - by bbftsoftware
    I have created a picker for my users to pick from a list of countries. The problem is that repeated opening and closing of the picker is resulting in “EXC_BAD_ACCESS” error. I suspect it might be a memory leak but I am not sure. I was hoping someone could shed some insight into why this might be happening? //data source for UIPicker NSArray *arrayCountryChoices; arrayCountryChoices = [[NSArray alloc] initWithObjects:@"TK=TOKELAU", @"TJ=TAJIKISTAN", @"TH=THAILAND", @"TG=TOGO", @"TF=FRENCH SOUTHERN TERRITORIES", @"GY=GUYANA", @"TD=CHAD", nil]; //opening the picker CountryViewController *countryVC = [[CountryViewController alloc] initWithNibName:@"CountryView" bundle:nil]; countryVC.delegate = self; [self presentModalViewController:countryVC animated:YES]; [countryVC release]; //here is where I grab the data //close country selector [self dismissModalViewControllerAnimated:YES]; //parse out code NSString *strCode = [chosenCountry substringToIndex:2]; //set the gui txtCountry.text = strCode; I think it may be because I am trying to release the Country Selector before the delegate has a chance to get its data? Also I am wondring if I should not release the picker until the screen that calls it is released. Thanks in advance.

  • Getting Android SDK WebView and TabWidget to play nice

    - by jdandrea
    I’m taking the HelloTabWidget Android example and trying two things: Moving the tabs to the bottom vs. the top (if that’s even desirable from an Android UI POV) Making each tab show a particular WebView in the space above I’ve got this for a layout (high level): <TabHost> <LinearLayout> <FrameLayout> <WebView/> <WebView/> <WebView/> <WebView/> <WebView/> </FrameLayout> <TabWidget/> </LinearLayout> </TabHost> Everything has a width/height set to fill_parent except for the TabWidget which has its layout_height set to wrap_content (and the layout_gravity set to bottom). First thing I noticed is that WebViews don’t show anything until all the parents have width/height set to fill_parent. However, once I do that, they fill the entire display, obscuring the TabWidget. Is there some other trick to making these two views play nicely together?

  • Vimeo videos in iPhone app

    - by thomasvsundert
    Hi guys, I was wondering if there's a way to "embed" a Vimeo video in an iPhone app. For YouTube videos I'm using a webview containing the correct embed code for the YouTube video and the iPhone's native YouTube support will then transform the flash player into a YouTube button. Is there a similar way to play Vimeo videos from my app? Maybe someone knows the correct <video>-src for Vimeo videos? thanks, Thomas

    Hi, I'd like to make an autosuggest app that connects to a .NET web service for the iPhone. Any tips on how to do it? Alternatively, would it be a good idea to cache a list of the most frequently used results on the iPhone and access the service if no results are available? Thanks, Teja

  • Multiple computers with a standard iPhone developer program

    - by Tiago
    I have enrolled on the standard iPhone Developer Program and I've successfully created a provisioning profile for my iMac. But I also have a MacBook Pro that I use to work while I'm traveling. But with the standard iPhone Developer Program there seems to be no way to have 2 computers to work, unless I spend time revoking and re-creating/re-validating certification authorities when switching machines. Am I right? Or is there some way to use the same CA across multiple machines?

  • iPhone SDK - UITabBarConroller and custom design

    - by Cheryl
    Hi I am having a problem with my tab bars at the bottom of the screen. The designer has decided it should be one colour (not black) when inactive and another colour when active. I have worked out how to replace the main colour of the tabbar by subclassing UITabBarController and doing this:- - (void)viewDidLoad { [super viewDidLoad]; CGRect frame = CGRectMake(0.0, 0, self.view.bounds.size.width, self.view.bounds.size.height); UIView *v = [[UIView alloc] initWithFrame:frame]; //get percentage values from digitalcolour meter and enter as decimals v.backgroundColor = [UIColor colorWithRed:.0 green:.706 blue:.863 alpha:1]; [tabBar1 insertSubview:v atIndex:0]; [v release]; } I just can't see how to make the active tabbar be a separate colour when it is selected. I have tried subclassing UITabBarItem but there doesn't seem to be any property for me to set to change the background colour of the tab. They also want to have the icons on the tab bar not be blue and grey and I can't figure out how to do that. In the ViewController for one tab bar item I have put this into viewdidload:- myTabBarItem *tabItem = [[myTabBarItem alloc] initWithTitle:@"listOOO" image:[UIImage imageNamed:@"starcopy.png"] tag:1]; tabItem.customHighlightedImage=[UIImage imageNamed:@"starcopy.png"]; self.tabBarItem=tabItem; [tabItem release]; tabItem=nil; and in my subclass of UITabBarItem I have put this:- -(UIImage *) selectedImage{ return self.customHighlightedImage; } Only I don't see the icon at all. If I put this into the viewDidLoad of my subclass of UITabBarController:- for (UITabBarItem *item in tabBar1.items){ item.image = [UIImage imageNamed:@"starcopy.png"]; } Then all my tab bars have the icon but they are blue (and grey when inactive) how would I get them not to become blue but stay their original colour? If you have any light on this problem please help as I have been banking my head on the wall for 2 days now and it's getting me down. Thanks in advance Cheryl

  • OpenAL tone generation on iPhone

    - by Sj
    So I have been looking around for some time now on a way to produce a variable tone on the iPhone using OpenAL, the issue being the Apple has deprecated the ALUT part of OpenAL that has the alutCreateBufferWaveform that would be perfect for this. I was wondering if anyone had any idea how to make a tone generator using OpenAL on the iPhone SDK. All I need is the ability to produce a certain frequency tone consistantly over and over again. This is a last resort so sorry if it sounds kind of stupid.

  • Base64 en/decoding between xstream and iPhone SDK

    - by Matt McMinn
    I am passing a byte array from a java server to an iPad client in XML. The server is using xstream to convert the byte array to XML with the EncodedByteArrayConverter, which should convert the array to Base 64. Using xstream, I can decode the xml back to the proper byte array in a java client, but in the iPad client, I'm getting an invalid length error. To do my decoding, I'm using the code at the bottom of this page. The length of the string is indeed not a multiple of 4, so there must be something strange with my string - although since xstream can decode it just fine, I'm guessing there's just something I need to to on the iPad side to get it to decode. I've tried cutting off padding at the end of the string to get it down to the right size, and that does allow the decoder to work, but I end up with JPG's that have invalid headers, and are not displayable. On the server side, I'm using the following code: Object rtrn = getByteArray(); XStream xstream = new XStream(); String xml = xstream.toXML(rtrn); On the client side, I'm calling the above decoder from the XML parsing callback like this: -(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string { NSLog(@"Converting data; string length: %d", [string length]); //NSLog(@"%@", string); NSData *data = [Base64 decode:string]; NSLog(@"converted data length: %d", [data length]); } Any ideas what could be going wrong?

    Hi all, I am using iPhone OS 3.0 SDK. My requirement is that I want to get the image from the photo albums library and display it on an image view. I am using the "UIImagePickerController" for that. But the problem is the "- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)imageeditingInfo:(NSDictionary *)editingInfo" delegate method is deprecated in iPhone OS 3.0 , so is there any alternative for getting the Image from the UIImagePickerController. All suggestions are highly appreciated. Thanks...
