iOS utility class to manage global dispatch queue.


(It's a component of [YYKit](https://github.com/ibireme/YYKit))



When use a concurrent queue to execute lots of blocks, I met this problem in some situation:








When some block is locked, the concurrent queue may create lots of thread and may block the main thread.

Use a global serial queue pool to avoid it.



Usage

==============

```objc

// Get a serial queue from global queue pool

dispatch_queue_t queue = YYDispatchQueueGetForQOS(NSQualityOfServiceUtility);



// Create a serial queue pool

YYDispatchQueuePool *pool = [[YYDispatchQueuePool alloc] initWithName:@"file.read" queueCount:5 qos:NSQualityOfServiceBackground];

dispatch_queue_t queue = [pool queue];

```



Installation

==============



### CocoaPods



1. Add `pod 'YYDispatchQueuePool'` to your Podfile.

2. Run `pod install` or `pod update`.

3. Import \.



### Carthage



1. Add `github "ibireme/YYDispatchQueuePool"` to your Cartfile.

2. Run `carthage update --platform ios` and add the framework to your project.

3. Import \.



### Manually



1. Download all the files in the YYDispatchQueuePool subdirectory.

2. Add the source files to your Xcode project.

3. Import `YYDispatchQueuePool.h`.



Documentation

==============

Full API documentation is available on [CocoaDocs](http://cocoadocs.org/docsets/YYDispatchQueuePool/).


You can also install documentation locally using [appledoc](https://github.com/tomaz/appledoc).



Requirements

(该项目是 [YYKit](https://github.com/ibireme/YYKit) 组件之一)



当用 concurrent queue 来执行大量 block 时，有时会遇到下面这种情况：








当某个 block 所在线程被锁住时，concurrent queue 会创建大量线程以至于占用了过多资源而影响到主线程。这里可以用一个全局的 serial queue pool 来尽量控制全局线程数。



用法

==============

```objc

// 从全局的 queue pool 中获取一个 queue

dispatch_queue_t queue = YYDispatchQueueGetForQOS(NSQualityOfServiceUtility);

	

// 创建一个新的 serial queue pool

YYDispatchQueuePool *pool = [[YYDispatchQueuePool alloc] initWithName:@"file.read" queueCount:5 qos:NSQualityOfServiceBackground];

dispatch_queue_t queue = [pool queue];

```

	

安装

==============



### CocoaPods



1. 在 Podfile 中添加 `pod 'YYDispatchQueuePool'`。

2. 执行 `pod install` 或 `pod update`。

3. 导入 \。



### Carthage



1. 在 Cartfile 中添加 `github "ibireme/YYDispatchQueuePool"`。

2. 执行 `carthage update --platform ios` 并将生成的 framework 添加到你的工程。

3. 导入 \。



### 手动安装



1. 下载 YYDispatchQueuePool 文件夹内的所有内容。

2. 将 YYDispatchQueuePool 内的源文件添加(拖放)到你的工程。

3. 导入 `YYDispatchQueuePool.h`。
