  • iPhone Settings app and keyboard control?

    - by randallmeadows
    So I'm putting my app's preference settings into the Settings app. One of the settings is an edit text field (PSTextFieldSpecifier). When touched, the keyboard dutifully appears, I can make the edits, but when I press Return....nothing. Well, the editing is completed, but the keyboard remains. I see no way to make the keyboard go away. I also notice this same behavior in other Settings panes, including those from Apple. Do I assume correctly that this is just standard behavior and I need to just accept the fact that my Settings table has now been reduced to half size, and just deal? Furthermore, I gather there is no approved way to have a "rich" child pane display, such as that seen in Settings-General-About-Legal? Or a way to do what appears to be a -presentModalViewController, a la Settings-General-Passcode Lock?

  • Problem in Autoresizing subviews in iPhone programmatically

    - by Cathy
    Hi, I have created a UIViewController and a UIView with two UIButtons in it. self.view = [[UIView alloc]initWithFrame:CGRectMake( 0,0,320,480)]; self.view.autoresizesSubviews = YES; self.view.backgroundColor = [UIColor redColor]; UIView *view; view = [[UIVew alloc]initWithFrame:CGRectMake(0,0,320,480)]; view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; UIButton *button1; button.frame = CGRectMake(100,130,120,50); [button addTarget:self action:@selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside]; [view addSubview:button]; [controller addSubview:view]; -(void)buttonAction:(id)sender { //I have created another view for a purpose [view removeFromSuperview]; UIView *view_obj; **view_obj.backgroundColor = [UIColor greenColor];** view_obj.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleWidth; [self.view addSubview:view_obj]; } Problem: When I change the orientation into landscape the view which has the button is resized but when i click on the button the view with the blueColor is displayed without autoresized. Where i can see half as root view in redColor and half as the subview in greenColor.I have also overrided the ShouldAutoRotate method and done this project programmatically. Please do reply me.

  • iPhone - Dismiss modal view by a UITabBarController

    - by ncohen
    Hi everyone, I've got into a very strange problem. I created my own UITabBarController to customize it and it works pretty well... except for the modal views. When I dismiss the modal view (present/dismiss from the UITabBarController) with an animation, it waits until the animation did finished and goes to the first controller of the tab bar! Why does the controller change? and how can I fix it? Thanks PS: My UITabBarController view is on the main window and has a UITabBar on it. The controllers (which are managed by the tab bar) are on the main window over the tab bar controller view with a shorter height. When I present the modal view, I bring the tab bar controller view to front.

  • Objective C / iPhone comparing 2 CLLocations /GPS coordinates

    - by user289503
    have an app that finds your GPS location successfully, but I need to be able to compare that GPS with a list of GPS locations, if both are the same , then you get a bonus. I thought I had it working, but it seems not. I have 'newLocation' as the location where you are, I think the problem is that I need to be able to seperate the long and lat data of newLocation. So far ive tried this: Code: NSString *latitudeVar = [[NSString alloc] initWithFormat:@"%g°", newLocation.coordinate.latitude]; NSString *longitudeVar = [[NSString alloc] initWithFormat:@"%g°", newLocation.coordinate.longitude]; An example of the list of GPS locations: Code: location:(CLLocation*)newLocation; CLLocationCoordinate2D bonusOne; bonusOne.latitude = 37.331689; bonusOne.longitude = -122.030731; and then Code: if (latitudeVar == bonusOne.latitude && longitudeVar == bonusOne.longitude) { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"infinite loop firday" message:@"infloop" delegate:nil cancelButtonTitle:@"Stinky" otherButtonTitles:nil ]; [alert show]; [alert release]; this comes up with an error 'invalid operands to binary == have strut NSstring and CLlocationDegrees' Any thoughts?

  • 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

  • best-practices for displaying new view controllers ( iPhone )

    - by Tristan
    I need to display a couple of view controllers (eg, login screen, registration screen etc). What's the best way to bring each screen up? Currently for each screen that I'd like to display, I call a different method in the app delegate like this: Code: - (void) registerScreen { RegistrationViewController *reg = [[RegistrationViewController alloc] initWithNibName:@"RegistrationViewController" bundle:nil]; [window addSubview:reg.view]; } - (void) LoginScreen { LoginViewController *log = [[LoginViewController alloc] initWithNibName:@"LoginViewController" bundle:nil]; [window addSubview:log.view]; } It works, but I cant imagine it being the best way.

  • iphone tab bar controller and core data.

    - by Sway
    Ok bit of a newbie type question. I want to use Core Data, together with Tab and Navigation controllers. In XCode if I create a Navigation Based Application I get the option to choose Core Data. Whereas If I create a Tab Bar Application I don't get the choice. I understand that Tab Bars display view controllers so it kinda makes sense. However given that by default it sticks the basic Core Data code in the Application delegate I don't see why this isn't offered. At the moment I'm creating the two projects and cutting and pasting between them. Does this omission in XCode seem weird to you? Is it some sort of oversight? Thanks, Matt

  • [iPhone] Background color during flip view animation/transition?

    - by Rob S.
    I have some pretty standing flipping action going on: [UIView beginAnimations:@"swapScreens" context:nil]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; [UIView setAnimationDuration:1.0]; [self.view exchangeSubviewAtIndex:0 withSubviewAtIndex:1]; [UIView commitAnimations]; To Apple's credit, this style of animation is amazingly easy to work with. Very cool, and I've been able to animate transitions, flips, fades etc. throughout the app very easily. Question: During the flip transition, the background visible 'behind' the two views during the flip is white and I'd like it to be black. I've: Set the background of the containing view (self.view above) - no dice. I really thought that would work. Set the background of each view to black - no dice. I didn't think this would work although you give different things a shot to understand better :) Google'd like crazy; keep landing on Safari-related listings. Thanks in advance!

  • Detect file creation date on iPhone OS?

    I was planning on writing some code whose logic was based upon testing the creation date of a particular file in my app's Documents folder. Turns out, when I call -[NSFileManager attributesOfItemAtPath:error:], NSFileCreationDate isn't one of the provided attributes. Is there no way to discover a file's creation date? Thanks.

  • Simultaneous gesture recognizers in Iphone SDK

    - by minaevs
    I need to catch two different swipping gestures using UISwipeGestureRecognizer(for example, UISwipeGestureRecognizerDirectionRight and UISwipeGestureRecognizerDirectionLeft). When I add two different recognisers with addGestureRecognizer method, only last added recognizer works. I've read that I need to implement gestureRecognizer:shouldRecognizeSimultaneouslyWithGestureRecognizer: method of UIGestureRecognizerDelegate protocol, but nothing works. Can anyone help with simple example of catching two or more same gestures? Thanks!

  • iPhone: Changing CGImageAlphaInfo of CGImage

    - by TechZen
    I have a PNG image that has an unsupported bitmap graphics context pixel format. Whenever I attempt to resize the image, CGBitmapContextCreate() chokes on the unsupported format (Error formatted for easy reading): CGBitmapContextCreate: unsupported parameter combination: 8 integer bits/component; 32 bits/pixel; 3-component colorspace; kCGImageAlphaLast; 1344 bytes/row. The list of supported pixel formats definitely does not support this combination. It appears I need to redraw the image and move the alpha channel information to kCGImageAlphaPremultipliedFirst or kCGImageAlphaPremultipliedLast. I have no idea how to go about doing this. There is nothing unusual about the PNG file and it isn't corrupted. It works in all other context just fine. I encountered this error just by chance but obviously my users might have similarly formatted files so I will have to check my app's imported images and correct for this problem.

  • iPhone Provisioning Profile problems...

    - by James
    I have already successfully submitted two apps to the app store, so I should be able to do it by now, right? With my most recent app, however, I'm having a bear of a time with getting the Application Identifier or Bundle Identifier set up. In my distribution profile, I have included the identifier "com.jmock.irowbeta", and then copied it exactly into the the app's Info.plist file under "Bundle Identifier". In the past, this has done the trick, but now I'm getting the error Provisioning profile 'irow beta' specificies the identifier 'com.jmock.irowbeta' which doesn't match the current setting 'com.yourcompany.irow-beta'. So it seems that its somehow still using the default of com.yourcompany.APPLICATION_NAME, but it shouldn't after I have changed it in the Info.plist, right? I think this means that xcode isn't recognizing that PLIST for some reason, because when I change the name of the icon file, for example, or other such attributes, nothing changes. If this is the problem, how do I make xcode recognize the PLIST? Otherwise, what the heck is going on? Thanks, James

  • Iphone UIScrollView and multiple visible images

    - by joynes
    Hi! Im trying to implement a UIScrollView including multiple images, using paginate. The problem is that I want more then one page to be visible in the UIScrollView, but only one page should be selected. I found several solutions in which you handle touch down/up (touchesBegan and touchesEnded) myself and scrollRectToVisible, but I want to avoid this if possible. A sample solution for that can be found at: http://forums.macrumors.com/showthread.php?t=634462 I dont get why its so easy if you only need to display one page at a time in the UIScrollView , but seems really hard if you want to show more pages. Could you solve it with zooming? /Br Johannes

    Not sure if what I want to do makes sense, but I want to take advantage of the UITabBarController and the TTNavigator from Three20. Any tutorials around that demonstrate how this can be done? I understand how to add view controllers to the navigator using the TTURLMap, but do I need to add a navigator for each tabbar item? I'm lost.

  • iPhone provisioning profile suddenly stops working (not expired)

    - by Tristan
    Hey there! We have a couple of iPhones in our office. All of them have provisioning profiles installed on them. One of the phones (my bosses :S) all of a sudden won't allow me to install apps to it, complaining that a valid provisioning profile cannot be found. The profile isn't expired, and the problem is, I'm guessing, not with the XCode files, as I can install the same project to all the other phones. Does anyone know why this might have occurred or how I can fix this? Thanks! Tristan
