Make carthage portable
Mar 23, 2019
I wanna run carthage without install CarthageKit.framework to system library. Download latest release get latest carthage pkg form https://github.com/Carthage/Carthage/releases Extract pkg file pkgutil --expand-full Carthage.pkg Carthage Copy to system path cp Carthage/CarthageApp.pkg/Payload/usr/local/bin/carthage /usr/local/bin mkdir -p /usr/local/Library/Frameworks cp -r Carthage/CarthageApp.pkg/Payload/Library/Frameworks/CarthageKit.framework /usr/local/Library/Frameworks Add rpath for carthage install_name_tool -add_rpath @executable_path/../Library/Frameworks /usr/local/bin/carthage install_name_tool -add_rpath @executable_path/../Library/Frameworks/CarthageKit.framework/Versions/Current/Frameworks /usr/local/bin/carthage All done. I using a shell script make it easy #!/bin/bash set -e if [ ! -f Carthage.pkg ]; then echo Carthage.pkg not found. exit -1 fi if [ -d Carthage ]; then echo found Carthage, removed rm -rf Carthage fi pkgutil --expand-full Carthage.pkg Carthage mkdir -p Carthage_portable/bin mkdir -p Carthage_portable/Library/Frameworks cp Carthage/CarthageApp.pkg/Payload/usr/local/bin/carthage Carthage_portable/bin cp -r Carthage/CarthageApp.pkg/Payload/Library/Frameworks/CarthageKit.framework Carthage_portable/Library/Frameworks rm -rf Carthage install_name_tool -add_rpath @executable_path/../Library/Frameworks Carthage_portable/bin/carthage install_name_tool -add_rpath @executable_path/../Library/Frameworks/CarthageKit.framework/Versions/Current/Frameworks Carthage_portable/bin/carthage echo Make Carthage portable at Carthage_portable echo Testing Carthage_portable/bin/carthage version Carthage_portable/bin/carthage version

A simple Dispatch Queue Pool
Mar 18, 2019
I named it MDispatchQueuePool. Really easy to use: [MDispatchQueuePool.sharedPool asyncExecute:^{ // put your code here ... }]; Here is MDispatchQueuePool.m @interface MDispatchQueuePool () { dispatch_queue_t _executionQueue; dispatch_queue_t _waitingQueue; dispatch_semaphore_t _maximumQueueSemaphore; } @end @implementation MDispatchQueuePool + (instancetype)sharedPool { static MDispatchQueuePool *pool = nil; static dispatch_once_t onceToken = 0; dispatch_once(&onceToken, ^{ pool = [[self alloc] init]; }); return pool; } - (instancetype)init { if (self = [super init]) { _executionQueue = dispatch_queue_create("queue.exec.MDispatchQueuePool", DISPATCH_QUEUE_CONCURRENT); _waitingQueue = dispatch_queue_create("queue.wait.MDispatchQueuePool", DISPATCH_QUEUE_SERIAL); dispatch_set_target_queue(_executionQueue, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0)); dispatch_set_target_queue(_waitingQueue, dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)); NSUInteger processorCount = MAX(NSProcessInfo.processInfo.processorCount, 2); _maximumQueueSemaphore = dispatch_semaphore_create(processorCount); } return self; } - (void)asyncExecute:(dispatch_block_t)block { if (!block) { return; } dispatch_block_t blockCopy = [block copy]; dispatch_async(_waitingQueue, ^{ dispatch_semaphore_wait(self->_maximumQueueSemaphore, DISPATCH_TIME_FOREVER); dispatch_async(self->_executionQueue, ^ { blockCopy(); dispatch_semaphore_signal(self->_maximumQueueSemaphore); }); }); } @end
