steipete / NSData+PSPDFFoundation.m

Created July 16, 2015 08:08

After playing around with dispatch_io (https://gist.github.com/steipete/b22babbf3014e29c19f0), I ended up with this. Upside: Uses way less memory, controllable caching, similar performance, simpler code and supports priority donation implicitly since everything's sync.

	static NSData PSPDFCalculateSHA256FromFileURL(NSURL fileURL, CC_LONG dataLength, NSError **error) {
	NSCParameterAssert(fileURL);

	NSData *shaData;

	int fd = open(fileURL.path.UTF8String, O_RDONLY);
	if (fd < 0) {
	if (error) *error = [NSError pspdf_errorWithCode:PSPDFErrorCodeUnableToOpenPDF description:@"Failed to open file for calculating SHA256."];
	return nil;
	}

Workaround for rdar://18906964: Moving UIViewController from one window to another breaks rotation in iOS 8.1

	@implementation FullscreenWindow

	- (void)setRootViewController:(UIViewController *)rootVC {
	// Try to clear the existing interface orientation, fixes rdar://18906964.
	// Apparantly in iOS 8.1 the interface orientation doesn't correctly clears out,
	// which then leads to weird rotation issues.
	@try {[rootVC setValue:@(UIInterfaceOrientationPortrait) forKey:NSStringFromSelector(@selector(interfaceOrientation))];}
	@catch (NSException *exception) {}
	[super setRootViewController:rootVC];

	/**
	Provides the ability to verify key paths at compile time.

	If "keyPath" does not exist, a compile-time error will be generated.

	Example:
	// Verifies "isFinished" exists on "operation".
	NSString *key = SQKeyPath(operation, isFinished);

	// Verifies "isFinished" exists on self.

The xib compiler in Xcode 5.0.1 always sets the scaling bit of all NSViews which results in dramatically reduced performance. Until Apple fixes this severe bug, we work around this by patching NSKeyedUnarchiver to clear the bit during decoding of the compiled xib files. By the way: We filed this bug three months ago under rdar://14359398.

	@interface NSKeyedUnarchiver (Xcode5Fix)
	@end

	@implementation NSKeyedUnarchiver (Xcode5Fix)

	+ (void)load
	{
	[self exchangeInstanceMethod:@selector(decodeInt32ForKey:)
	withMethod:@selector(xcode5Fix_decodeInt32ForKey:)];
	}

This is a guard that tracks down UIKit access on threads other than main. This snippet is taken from the commercial iOS PDF framework http://pspdfkit.com, but relicensed under MIT. Works because a lot of calls internally call setNeedsDisplay or setNeedsLayout. Won't catch everything, but it's very lightweight and usually does the job.You might n…

A tiny shell script for installing GNUstep and libobjc2 automatically on Ubuntu 12. I recommend that you download this script to a distinct folder "gnustep-installer". It will download and unpack a couple of tar packages. For more information see my blog post http://blog.tlensing.org/2013/02/24/objective-c-on-linux-setting-up-gnustep-clang-llvm-…

Avoiding the default [super init] boilerplate:

	* This macro is equivalent to:
