# ――― Spec Metadata ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# These will help people to find your library, and whilst it
# can feel like a chore to fill in it's definitely to your advantage. The
# summary should be tweet-length, and the description more in depth.
#
s.name = "MCDownloadManager"
s.version = "1.0.3"
s.summary = "A simple and convenient multi task download manager"
# This description is used to generate tags and improve search results.
# * Think: What does it do? Why did you write it? What is the focus?
# * Try to keep it short, snappy and to the point.
# * Write the description between the DESC delimiters below.
# * Finally, don't worry about the indent, CocoaPods strips it!
# s.description = <<-DESC
# A simple and convenient multi task download manager
# DESC
s.homepage = "https://github.com/agelessman/MCDownloadManager"
# s.screenshots = "www.example.com/screenshots_1.gif", "www.example.com/screenshots_2.gif"
# ――― Spec License ――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# Licensing your code is important. See http://choosealicense.com for more info.
# CocoaPods will detect a license file if there is a named LICENSE*
# Popular ones are 'MIT', 'BSD' and 'Apache License, Version 2.0'.
#
s.license = "MIT"
# s.license = { :type => "MIT", :file => "FILE_LICENSE" }
# ――― Author Metadata ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# Specify the authors of the library, with email addresses. Email addresses
# of the authors are extracted from the SCM log. E.g. $ git log. CocoaPods also
# accepts just a name if you'd rather not provide an email address.
#
# Specify a social_media_url where others can refer to, for example a twitter
# profile URL.
#
s.author = { "machao" => "714080794@qq.com" }
# Or just: s.author = "machao"
# s.authors = { "machao" => "714080794@qq.com" }
# s.social_media_url = "http://twitter.com/machao"
# ――― Platform Specifics ――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# If this Pod runs only on iOS or OS X, then specify the platform and
# the deployment target. You can optionally include the target after the platform.
#
# s.platform = :ios
s.platform = :ios, "7.0"
# When using multiple platforms
# s.ios.deployment_target = "5.0"
# s.osx.deployment_target = "10.7"
# s.watchos.deployment_target = "2.0"
# s.tvos.deployment_target = "9.0"

#
# Specify the location from where the source should be retrieved.
# Supports git, hg, bzr, svn and HTTP.
#
s.source = { :git => "https://github.com/agelessman/MCDownloadManager.git", :tag => "#{s.version}" }
# ――― Source Code ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# CocoaPods is smart about how it includes source code. For source files
# giving a folder will include any swift, h, m, mm, c & cpp files.
# For header files it will include any header in the folder.
# Not including the public_header_files will make all headers public.
#
s.source_files = "MCDownloadManager/MCDownloadManager/*.{h,m}"
s.exclude_files = "Classes/Exclude"
# s.public_header_files = "Classes/**/*.h"
# ――― Resources ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# A list of resources included with the Pod. These are copied into the
# target bundle with a build phase script. Anything else will be cleaned.
# You can preserve files from being cleaned, please don't preserve
# non-essential files like tests, examples and documentation.
#
# s.resource = "icon.png"
# s.resources = "Resources/*.png"
# s.preserve_paths = "FilesToSave", "MoreFilesToSave"
# ――― Project Linking ―――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# Link your library with frameworks, or libraries. Libraries do not include
# the lib prefix of their name.
#
s.framework = "Foundation", "UIKit"
# s.frameworks = "Foundation", "UIKit"
# s.library = "iconv"
# s.libraries = "iconv", "xml2"
# ――― Project Settings ――――――――――――――――――――――――――――――――――――――――――――――――――――――――― #
#
# If your library depends on compiler flags you can set them in the xcconfig hash
# where they will only apply to your library. If you depend on other Podspecs
# you can include multiple dependencies to ensure it works.
# s.requires_arc = true
# s.xcconfig = { "HEADER_SEARCH_PATHS" => "$(SDKROOT)/usr/include/libxml2" }

# MCDownloadManager
A simple and convenient multi task download manager
## Attention
这个版本默认只支持同时下载10个文件
This version only supports 10 file downloads at the same time.
若要支持更多，请修改下边的代码
`configuration.HTTPMaximumConnectionsPerHost = 10;`
**添加了速度提示（比如：400KB/s）**
**支持后台和锁屏下载**
## Installation
### Cocoapods
[CocoaPods](http://cocoapods.org) is a dependency manager for Cocoa projects. You can install it with the following command:
```bash
$ gem install cocoapods
```
> CocoaPods 1.1.0+ is required to build MCDownloadManager 1.0.0+.
To integrate MCDownloadManager into your Xcode project using CocoaPods, specify it in your `Podfile`:
```ruby
pod 'MCDownloadManager', '~> 1.0.3'
```
Then, run the following command:
```bash
$ pod install
```
## Usage
- (void)download {
[[MCDownloadManager defaultInstance] downloadFileWithURL:self.url
progress:^(NSProgress * _Nonnull downloadProgress, MCDownloadReceipt *receipt) {
if ([receipt.url isEqualToString:self.url]) {
self.progressView.progress = downloadProgress.fractionCompleted ;
}
}
destination:nil
success:^(NSURLRequest * _Nonnull request, NSHTTPURLResponse * _Nullable response, NSURL * _Nonnull filePath) {
[self.button setTitle:@"播放" forState:UIControlStateNormal];
}
failure:^(NSURLRequest * _Nonnull request, NSHTTPURLResponse * _Nullable response, NSError * _Nonnull error) {
[self.button setTitle:@"重新下载" forState:UIControlStateNormal];
}];
}
