steipete / PresentActionSheetWorkaround.mm

Last active January 27, 2020 04:32

UIKit has two places where it tries to present an action sheet on the rootViewController when it should present things on the topmost presentedViewController. This is our attempt of the least horrible workaround to fix this issue. (http://www.openradar.me/26295020).

	#warning This still misses safeguards and has private API references in it. Use only when you really know what you're doing!

Declare on your main init that all other init methods should call. It's a nice additional semantic warning. Works with Xcode 5.1 and above. Not tested with earlier variants, but should just be ignored. A reference to this macro shortly appeared in https://developer.apple.com/library/ios/releasenotes/ObjectiveC/ModernizationObjC/AdoptingModernObj…

beccadax / IndexSetEnumeration.m

Last active December 17, 2015 08:48

This gist includes a quick syntax for constructing NSIndexSets—[@0:9] and [@0:9 step:2]—and fast enumeration support for NSIndexSet (yielding NSNumbers). The result is that you can enumerate over ranges using for/in. The gist is CodeRunner ready.

	#import <Foundation/Foundation.h>

	@interface NSNumber (range)

	- (NSIndexSet*):(NSUInteger)max;
	- (NSIndexSet*):(NSUInteger)max step:(NSUInteger)step;

	@end
