AVFoundation, how to turn off the shutter sound when captureStillImageAsynchronouslyFromConnection?
I am trying to capture an image during a live preview from the camera, by AVFoundation captureStillImageAsynchronouslyFromConnection. So far the program works as expected. However, how can I mute the shutter sound?
How to extract AST from Objective-C code?
OP says I don't mind using any tool to extract AST from Objective-C code ... Our DMS Software Reengingineering Toolkit can do this for Objective-C. For this command line to the DMS-generated parser "domainparser": run \DMS\Domains\C\ObjectiveCv2\Tools\Parser\domainparser ++AST "C:\temp\test.m" this Objective C file "test.m": @implementation GTLClientLoginAuthorizationArgs @synthesize request = req
Pattern for unit testing async queue that calls main queue on completion
This is related to my previous question, but different enough that I figured I'd throw it into a new one. I have some code that runs async on a custom queue, then executes a completion block on the main thread when complete. I'd like to write unit test around this method. My method on MyObject looks like this. + (void)doSomethingAsyncThenRunCompletionBlockOnMainQueue:(void (^)())completionBlock {

xcodebuild says does not contain scheme
You are definitely on the right track with respect to the .xcscheme file -- I had this problem appear while setting up my own projects! For posterity, or at least anyone getting here from a search, here are two versions of things -- the "I'm busy, so just the facts please" version and a more involved discussion and rationale. Both of these versions assume you are trying to build from a Workspace f
How to implement a volume key shutter for iPhone?
I want to implement the same behavior with the native camera of iOS5: press the volume + button to take a photo What's the ideal way to archive it? Are there any ways to capture the volume key pressed event? After googling & searching around for hours, I found 1 solution: using NSNotificationCenter: ... [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(volumeChanged:) name:
XCTAssertEqual error: ("3") is not equal to ("3")
I have also had quite a bit of trouble with Xcode 5's tests. It still seems quite buggy with some odd behaviour - however I have found the definitive reason your particular XCTAssertEqual isn't working. If we have a look at the test code we see it actually does the following (taken directly from XCTestsAssertionsImpl.h - it may be easier to view there): #define _XCTPrimitiveAssertEqual(a1, a2, for
A ViewModel pattern for iOS apps with ReactiveCocoa
I'm working on integrating RAC into my project with the goal of creating a ViewModel layer that will allow easy caching/prefetching from the network (plus all of the other benefits of MVVM). I'm not especially familiar with MVVM or FRP yet, and I'm trying to develop a nice, reusable pattern for iOS development. I have a couple of questions about this. First, this is sort of how I've added a ViewMo
UIView backgroundColor disappears when UITableViewCell is selected
I have a simple tableViewCell build in interface builder. It contains a UIView which contains an image. Now, when I select the cell, the default blue selection background is shown, but the backgroundColor of my UIView is gone. My UITableViewCell's implementation file doesn't do anything special. It just init's & returns self and all I do in setSelected is call super. How do I get my UIView backgro
