  • Add subview to another view

    - by Martol1ni
    With two ViewControllers, MyView 1 and MyView 2, is there possible to add a subview to MyView2 from MyView1.m? I have tried: MyView2 * screen = [[MyView2 alloc]initWithNibName:nil bundle:nil]; [screen.view addSubView:mySubView]; But my new instance of MyView 2 has no connection to the 'visible' ViewController on MyView2, right? To clarify, the ViewController that is showing, is MyView1. I want MyView1 to be able to add a subview to the MyView2 view. Thanks

  • Find Exact difference between two dates

    - by iPhone Fun
    Hi all , I want some changes in the date comparison. In my application I am comparing two dates and getting difference as number of Days, but if there is only one day difference the system shows me 0 as a difference of days. I do use following code NSDateFormatter *date_formater=[[NSDateFormatter alloc]init]; [date_formater setDateFormat:@"MMM dd,YYYY"]; NSString *now=[NSString stringWithFormat:@"%@",[date_formater stringFromDate:[NSDate date]]]; LblTodayDate.text = [NSString stringWithFormat:@"%@",[NSString stringWithFormat:@"%@",now]]; NSDate *dateofevent = [[NSUserDefaults standardUserDefaults] valueForKey:@"CeremonyDate_"]; NSDate *endDate =dateofevent; NSDate *startDate = [NSDate date]; gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; unsigned int unitFlags = NSDayCalendarUnit; NSDateComponents *components = [gregorian components:unitFlags fromDate:startDate toDate:endDate options:0]; int days = [components day]; I found some solutions that If we make the time as 00:00:00 for comparision then it will show me proper answer , I am right or wrong i don't know. Please help me to solve the issue

  • Zooming to UIView and it's sub-views

    - by leon
    Hi, I have a UIView which I can zoom to (as it is set as a subview of UIScrollView). UIView has UILabel, UITextField, etc. If I just zoom to the UIView, then of course label and text field get fuzzy (the same effect if you are zooming to the image file without changing image resolution). To solve the problem I need to increase the font size and sizes of the UILable and UITextField in according to the scale used to zoom in (scale is passed as a param by the UIScrollView). This is where I am getting confused. Changing frame (by increasing it width and height by zooming scale) I get all my elements (sub-views) repositions (because changing frame effects center and bounds) Question: 1. What would I need to do to zoom in to the sub-views and just increase the sub-view sizes while keeping them in the exactly the same position? thanks

  • How big can I make an Android application's canvas in terms of pixels?

    - by user279112
    I've determined an estimate of the size of my Android emulator's screen in pixels, although I think its resolution can be changed to other numbers. Quite frankly though that doesn't eliminate the general problem of not knowing how many pixels on each axis I have to work with on my Android applications in general. The main problem I'm trying to solve is this: How do I make sure I don't use a faulty resolution on Android applications if I want to keep things' sizes constant (so that if the application screen shrinks, for instances, objects will still show up just as big - there just won't be as many of them being shown) if I wish to do this with a single universal resolution for each program? Failing that, how do I make sure everything's alright if I try to do everything the same way with maybe a few different pre-set resolutions? Mainly it seems like a relevant question that must be answered before I can come across a complete answer for the general problem is how big can I always make my application in pixels, NOT regarding if and when a user resizes the application's screen to something smaller than the maximum size permitted by the phone and its operating system. I really want to try to keep this simple. If I were doing this for a modern desktop, for instance, I know that if I design the application with a 800x600 canvas, the user can still shrink the application to the point they're not doing themselves any favors, but at least I can basically count on it working right and not being too big for the monitor or something. Is there such a magic resolution for Android, assuming that I'm designing for API levels 3+ (Android 1.5+)? Thanks

  • UIWebView - remote html loading local images

    - by AragornSG
    I'm trying to develop an application using UIWebView. The app is loading remote URL's, so in order to make it quick I want it to use the images included in the application bundle. I was wondering if there is a way to do it without forcing the application to manually replace the address of each image to point into local resources?

  • Can't get ellipsis to work on Android

    - by Mark
    Hi, I have a TextView. I want it to ellipsize if longer than its available width. This does not work unless the input string has no spaces... can anyone provide an example of this working? I've tried different combinations of: singleLine="true" maxLines="1" scrollHorizontally="false" none of these have any effect. Again, if I supply a string that has no spaces in it, then the ellipsis appears correctly. What am I missing? I've tried this on 1.5, 1.6, 2.0, all same problem. Thanks

  • Three20 Library Cannot find its own headers Xcode iPhone

    - by DieLaughing
    import "Three20/Three20.h" Fails. Go download it and build a sample app. If that works, then make a new app from the templates provided, then watch as it fails spectacularly to find the right HEADER_SEARCH_PATH. 1) I've gone to the info page for the TARGET and not the PROJECT (Well, I tried both) and tried a bunch of different paths for the HEADER_SEARCH_PATH field. 2) I've tried dragging and dropping the dependent files from the finder and COPYING or just referencing both fails. (RANT: WTF?! Really? I wish public code libraries saved me time ONCE in my life.)

  • Get name given by phone number on the iPhone

    - by ganti
    I'm using a TextField where the user types a phone number. When the TextField changes, it should check if this number is already in the phonebook and display the name. So far, my only way is to parse all names and number in a Dict and read it from there. Is there a simpler, more efficient and sophisticated way to do that?

  • Help modifying QuartzDemo example application

    - by BittenApple
    Can anyone please, oh sweet pain, please take me out of my misery by writing a simple example on how the heck you pass a number (int value) which gets created in 1 .m file to another .m file. In the apple demo application called QuartzDemo, there is a file called QuartzImages.m This file has the following line of code: [CODE]CGPDFPageRef page = CGPDFDocumentGetPage(pdf, 1);[/CODE] Notice the (pdf, 1) in that line. This number should be replaced with an integer variable. Now, there is also a file called MainViewController.m. In that file, there is a method? called -(void)viewDidLoad In that method, I want to assign a number to the integer variable which would replace the damn "1" with whatever number I want. I have been pulling my hair trying to get this done, reading beginning iPhone 3 Development book, dev documentation and God knows what not, without results. Any help would be greatly appreciated... Sigh.

I have been doing some google research and have found some online deciphers for Hex yet they all seem to struggle decrypting the code. I basically need to decipher this code, change some variables and repack it exactly how I found it but replacing a URL. How can I go about this? Are there any free online tools available? Many thanks.

Can anyone help get this linking with "Compile Source As" set to "Objective-C++"?

  • How to disable customization for the TabBar?

    - by mana
    Hey, within my App it should be forbidden to edit (customize) the TabBar. This means there should be no edit button and no other possibility to change the order of the items. (this is not my decision, the boss wants it that way :) ) I can't find a property to do this - so is this possible after all? cheers
