一组 Objective-C 扩展和宏，让您能够更快地编写代码。
使用 CocoaPods
dependency 'ConciseKit', '~> 0.1.2'或者
src/ 目录下的文件复制到您的项目中。#import "ConciseKit.h" [$ swizzleMethod:@selector(foo) with:@selector(bar) in:[Foo class]]
[$ swizzleMethod:@selector(foo) in:[Foo class] with:@selector(bar) in:[Bar class]]
[$ swizzleClassMethod:@selector(foo) with:@selector(bar) in:[Foo class]]
[$ swizzleClassMethod:@selector(foo) in:[Foo class] with:@selector(bar) in:[Bar class]]
[$ homePath] => path to user's home directory
[$ desktopPath] => path to user's desktop directory
[$ documentPath] => path to user's document directory
[$ appPath] => path to app directory
[$ resourcePath] => path to app's resources directory
当编写异步任务的测试时非常有用。默认超时时间是 10 秒，每 0.1 秒检查一次。
[$ waitUntil:^{ return (BOOL)(someConditionIsMet == YES) }]
[$ waitUntil:^{ return (BOOL)(someConditionIsMet == YES) } timeOut:10.0]
[$ waitUntil:^{ return (BOOL)(someConditionIsMet == YES) } timeOut:10.0 interval:0.1]

return self;
