A Comprehensive PathFinding Library for Objective-C.
Based on PathFinding.js by @qiao.

• Edit your Podfile

pod 'PathFindingForObjC'

or use the master branch of the repo :

pod 'PathFindingForObjC', :git => 'https://github.com/wbcyclist/PathFindingForObjC.git'

• Add #import <PathFindingForObjC/PathFinding.h> to your source file.

Disable logging

add this code in Podfile

post_install do |installer|
	installer.project.targets.each do |target|
		target.build_configurations.each do |config|
			if target.name.include? 'PathFindingForObjC'
				preprocessorMacros = config.build_settings['GCC_PREPROCESSOR_DEFINITIONS']
				if preprocessorMacros.nil?
					preprocessorMacros = ['$(inherited)', 'COCOAPODS=1'];
				end
				preprocessorMacros << 'PF_DEBUG=0'
				config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] = preprocessorMacros
			end
		end
	end
end

1. Download the latest code version or add the repository as a git submodule to your git-tracked project.
2. Open your project in Xcode, then drag and drop PathFindingForObjC/PathFindingForObjC into your project
3. Add #import PathFinding.h to your source file.

Click on your Project Target, head over to Build Settings and search for Preprocessor Macros. add PF_DEBUG=0 to Debug Configuration.

PathFinding *finder = [[PathFinding alloc] initWithMapSize:CGSizeMake(6, 5)
												  tileSize:CGSizeMake(1, 1)
											   coordsOrgin:CGPointZero];
finder.heuristicType = HeuristicTypeManhattan;
finder.movementType = DiagonalMovement_Never;

// add blocks
[finder addBlockTilePositions:@[PF_CGPointToNSValue(CGPointMake(1, 2)),
								PF_CGPointToNSValue(CGPointMake(2, 2)),
								PF_CGPointToNSValue(CGPointMake(3, 2))
								]];
// set start point
finder.startPoint = CGPointMake(2, 3);
// set end point
finder.endPoint = CGPointMake(2, 1);
// get result
NSArray *foundPaths = [finder findPathing:PathfindingAlgorithm_AStar IsConvertToOriginCoords:YES];
