  • How to update a detailView in a splitViewController?

    - by pikebu
    Hello, I'm trying to update a detailView in a splitViewController. This is what I try: //Get the application delegate AppDelegate *delegate = [[UIApplication sharedApplication] delegate]; //Get the masterViewController MasterViewController *master = [delegate.splitViewController.viewControllers objectAtIndex:0]; This seems to work fine so far. Then I try to update a label in the detailViewController by doing this: master.detailViewController.myLabel.text = "someText"; But this doesn't work. (ignore the missing at sign in front of the "someText" - I have it, but it seems it's not allowed to put it in this forum.) So how is the right way to access the outlets of in the detailView? Thanks for help.

  • RegexKitLite Runtime Crash

    - by Hasan Can Saral
    I'm overlaying the mapview and using RegexKitLite. I couldn't make it work. I've downloaded .m and .h files and added to the project. Also I tried, adding libicucore.dylib or libicucore.A.dlib or adding -licucore to other compiler flags field. Still getting the error: 2012-04-01 19:38:04.633 sennerdeysen[907:15803] -[__NSCFString stringByMatching:capture:]: unrecognized selector sent to instance 0x88b6a00 2012-04-01 19:38:04.634 sennerdeysen[907:15803] * Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString stringByMatching:capture:]: unrecognized selector sent to instance 0x88b6a00' Any idea? Latest Xcode but the sdk is 4.3 Without ARC or anything else that iOS 5.0 SDK provides.

  • iOS6 Twitter integration

    - by Peter Warbo
    There seems to be a difference between the iPhone simulator and actual device when checking if Twitter is available. I check if a Twitter account is setup by using this code: [SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]; In the simulator there is a nice UIAlertView informing the user that there are no Twitter accounts setup and two buttons one for Settings and one for Cancel. However when I run my app on my device it will not show the above UIAlertView. Why is that? And how can I catch what button is tapped in the above UIAlertView (since I did not instantiate it?) This is what it looks like on the simulator:

  • iPhone GPS Development - Tips + Tricks

    - by Keith Fitzgerald
    Hello - I'm looking for some feedback, blog links, etc that offer some tips and tricks for iPhone GPS development. I've read and understand the API, I have my demo app up and running, etc but I have run into some "quirks" with gps on iphone. For example, it seems that you you will receive a lot less location updates when your iphone enters "power save" mode. I've read that you can combat this by playing music in your application [not sure if this is true]. It also seems that, terms of making a reasonable pedometer, you should filter out any reading with horizontal accuracies less than 20 meters. Does this sound right? Is there any kind of checklist out on the web for iphone gps gotchas? Thanks in advance.

  • How do I use an indeterminate status indicator as the image for an NSStatusItem?

    - by abrahamvegh
    I have an application that is an NSStatusItem. It has a few different modes, each of which require an external process to be launched, during which the icon is simply highlighted, and appears to be frozen. I want to use the -setImage method (or reasonable facsimile) to display something along the lines of a "spinner" commonly seen in web applications and all over OS X. Is there any native method for accomplishing this (e.g. some instance of NSProgressIndicator?) or must I manually display an animation by cycling through a set of images? In either case, how would I implement?

  • Implementing a horizontal compass on the iPhone - algorithm?

    - by Andrew Johnson
    A horizontal compass looks something like this if you are facing due East (90 degrees). 85----90---95 If you were facing due 355 degrees northwest, it would look like this: 350----355---0 As you turn the compass, the number should cycle from 0 - 360 - 0 So, my question is, how would you implement a view like this on the iPhone? I had a couple of ideas: Make one long image with all numbers and tick marks, and shift it left/right when the compass heading changes Create pieces of the view as tiles and append them when the compass heading changes. Create a line of tick marks that shifts with the compass heading, and just write numbers on it as needed. How would you attack this problem? Im mainly looking for algorithmic advice, but if you ave code or pseudo-code to demonstrate, that would be helpful too.

  • Multiple undo managers for a text view

    - by Rui Pacheco
    Hi, I've a text view that gets its content from an attributed string stored in a model object. I list several of these model objects in a drawer and when the user clicks on one the text view swaps its content. I now need to also swap the undo manager for the text view. I initialise an undo manager on my model object and use undoManagerForTextView to return it to the text view, but something's not quite right. Strategically placed logging statements show me that everything's working as planned: on startup a new model object is initialised correctly and a non-null undo manager is always pulled by the text view. But when it comes to actually doing undo, I just can't get the behaviour I want. I open a window, type something and press cmd+z, and undo works. I open a window, type something, select a new model on the table, type something, go back to the first model and try to undo and all I get is a beep. Something on the documentation made me raise an eyebrow, as it would mean that I can't have undo with several model objects: The default undo and redo behavior applies to text fields and text in cells as long as the field or cell is the first responder (that is, the focus of keyboard actions). Once the insertion point leaves the field or cell, prior operations cannot be undone.

  • Lazy load pages in UIScrollView

    - by jean
    I have a UIScrollView that contains large images and am using paging to scroll between images. In order to save memory, I am loading only one image before and after the currently visible one and loading/releasing new images after a scroll has completed. The problem occurs when one scrolls quickly and scrollViewDidEndDecelerating is not called. How can I detect continuous scrolling? I could check item location on every scrollViewDidScroll but this seems a bit heavy...

  • UITabBarController unresponsive for touches

    - by JustSid
    So, I have this view hierarchy in my app: UIWindow UIViewController UITabBarController -> 4 UINavigationController I know that a UITabBarController is designed to be the topmost view in an app, however this isn't possible in my case. However, the problem that I have is that ~20 of the lower pixels aren't responsive for touches so that the UITabBarController doesn't trigger the tab changes correctly. This happens on an actual device (iPad and iPhone 3G). My question is, are there any obvious reasons why this could happen? I add the UITabBarController like this as subview to my UIViewController view: - (void)viewDidLoad { [super viewDidLoad]; [self.view addSubview:controller.view]; // Controller is the UITabBarController } I didn't set the UITabBarController's delegate.

  • Callback for camera shutter open event

    - by Raj
    Hi all, I have been working around in UIImagePickerController and am struck with a problem where I need to get the precise moment when the camera shutter opens in UIImagePickerController when the source type is set to camera (UIImagePickerControllerSourceTypeCamera). I have done some googling around and have realized that no one had such strange requirement! I looked around the docs of UIImagePickerController and UIImagePickerControllerDelegate hoping to get some delegate method / callback indicating the camera shutter open event, but did not find any. Any suggestions? Thanks for any help, Raj Pawan

  • MVC - Calling Controller Methods

    - by JT703
    Hello, My application is following the MVC design pattern. The problem I keep running into is needing to call methods inside a Controller class from outside that Controller class (ex. A View class wants to call a Controller method, or a Manager class wants to call a Controller method). Is calling Controller methods in this way allowed in MVC? If it's allowed, what's the proper way to do it? According to the version of MVC that I am following (there seems to be so many different versions out there), the View knows of the Model, and the Controller knows of the View. Doing it this way, I can't access the controller. Here's the best site I've found and the one describing the version of MVC I'm following: http://leepoint.net/notes-java/GUI/structure/40mvc.html. The Main Program code block really shows how this works. Thanks for any answers.

  • MVC: Model View Controller -- does the View call the Model?

    - by Gary Green
    I've been reading about MVC design for a while now and it seems officially the View calls objects and methods in the Model, builds and outputs a view. I think this is mainly wrong. The Controller should act and retrieve/update objects inside the Model, select an appropriate View and pass the information to it so it may display. Only crude and rudiementary PHP variables/simple if statements should appear inside the View. If the View gets the information it needs to display from the Model, surely there will be a lot of PHP inside the View -- completely violating the point of seperating presentation logic.

  • CGContext rotation

    - by kasperjj
    I have a 100x100 pixel image that I want to draw at various angles rotated around the center of the image. The following code works, but rotates around the original origo of the coordinate system (upper left hand corner) and not the translated location. Thus the image is not rotated around itself but around the upper left corner of the screen. CGContextRef context = UIGraphicsGetCurrentContext(); CGContextTranslateCTM(context, -50, -50); CGContextRotateCTM (context, 0.3); CGContextTranslateCTM(context,768/2,1024/2); [image drawAtPoint:CGPointMake(0,0)]; I tried doing the same using CGAffineTransform, but got the same results.

  • Advantages of Thread pooling in embedded systems

    - by Microkernel
    I am looking at the advantages of threadpooling design pattern in Embedded systems. I have listed few advantages, please go through them, comment and please suggest any other possible advantages that I am missing. Scalability in systems like ucos-2 where there is limit on number of threads. Increasing capability of any task when necessary like Garbage collection (say in normal systems if garbage collection is running under one task, its not possible to speed it up, but in threadpooling we can easily speed it up). Can set limit on the max system load. Please suggest if I am missing anything.

  • Finding source of over release

    - by Benedict Lowndes
    Hi, I'm consistently seeing the same message sent in as a crash report from users of an app. It's clear that an object is being over-released but I'm unable to replicate it and I'm looking for tips on tracing the source of it. The relevant section from the crash report shows this: Application Specific Information: objc_msgSend() selector name: release Thread 0 Crashed: Dispatch queue: com.apple.main-thread 0 libobjc.A.dylib 0x90892edb objc_msgSend + 27 1 com.apple.CoreFoundation 0x95ec5a40 __CFBasicHashStandardCallback + 384 2 com.apple.CoreFoundation 0x95ec564e __CFBasicHashDrain + 478 3 com.apple.CoreFoundation 0x95ead6f1 _CFRelease + 353 4 com.apple.CoreFoundation 0x95eda0ed _CFAutoreleasePoolPop + 253 5 com.apple.Foundation 0x97ecedd6 NSPopAutoreleasePool + 76 6 com.apple.Foundation 0x97ececfe -[NSAutoreleasePool drain] + 130 7 com.apple.AppKit 0x9211255f -[NSApplication run] + 1013 8 com.apple.AppKit 0x9210a535 NSApplicationMain + 574 9 TheApp 0x000020a6 start + 54 I've used zombies and leaks, but haven't seen anything there. I've gone through the code and can't see it. What's the next step? Are there any hints I can discern from this information as to the source of it? Does the fact that this nearly exact same crash report is coming in repeatedly mean that it's the same object that's being over released, or because this is referring to the autorelease pool mean it could be any object? Does the reference to _CFRelease mean it's a Core Foundation object that's being over released?

  • Can I embed a custom font in an iPhone application?

    - by Airsource Ltd
    I would like to have an app include a custom font for rendering text, load it, and then use it with standard UIKit elements like UILabel. Is this possible? I found these links: http://discussions.apple.com/thread.jspa?messageID=8304744 http://forums.macrumors.com/showthread.php?t=569311 but these would require me to render each glyph myself, which is a bit too much like hard work, especially for multi-line text. I've also found posts that say straight out that it's not possible, but without justification, so I'm looking for a definitive answer. EDIT - failed -[UIFont fontWithName:size:] experiment I downloaded Harrowprint.tff (downloaded from here) and added it to my Resources directory and to the project. I then tried this code: UIFont* font = [UIFont fontWithName:@"Harrowprint" size:20]; which resulted in an exception being thrown. Looking at the TTF file in Finder confirmed that the font name was Harrowprint. EDIT - there have been a number of replies so far which tell me to read the documentation on X or Y. I've experimented extensively with all of these, and got nowhere. In one case, X turned out to be relevant only on OS X, not on iPhone. Consequently I am setting a bounty for this question, and I will award the bounty to the first person who provides an answer (using only documented APIs) who responds with sufficient information to get this working on the device. Working on the simulator too would be a bonus. EDIT - it appears that the bounty auto-awards to the answer with the highest nunber of votes. Interesting. No one actually provided an answer that solved the question as asked - the solution that involves coding your own UILabel subclass doesn't support word-wrap, which is an essential feature for me - though I guess I could extend it to do so.

  • setDelegate:self, how does it work?

    - by fuzzygoat
    I have a query regarding how delegates work. My understanding was that delegates take responsibility for doing certain tasks on behalf of another object. locationManager = [[CLLocationManager alloc] init]; [locationManager setDelegate:self]; [locationManager setDistanceFilter:kCLDistanceFilterNone]; [locationManager setDesiredAccuracy:kCLLocationAccuracyBest]; [locationManager startUpdatingLocation]; Am I right in thinking that in the example code above that the instance of CLLocationManager is created on a new thread so that it can get on with trying to find the location information it needs. When it completes its task (or encounters an error) it calls-back using the appropriate methods located in self e.g. locationManager:didUpdateToLocation:fromLocation: Essentially locationManager sends messages to self (which conforms to the correct delegate protocol) when things happen cheers gary

  • NSInteger differences between CLI and GUI ?

    - by d11wtq
    I've been building a framework and writing unit tests in GHUnit. One of my Framework's accessor methods returns an NSInteger. I assert the expected value in the tests like this: GHAssertEquals(1320, request.port, @"Port number should be 1320"); When running my tests with an AppKit UI based frontend this assertion passes. However, when I run my tests on the command line, it fails with a type-mismatch unless I type-cast my hard-coded 1320 as (NSInteger). What's causing the difference in the way the integer is being interpreted by the compiler? Is xcodebuild on the command line using a different data-type for hard coded integers?
