Objective-C工具包 ConciseKit
ConciseKit 是一组 Objective-C 的附加组件和宏,用于简化编码工作。
USAGE
Use CocoaPods
dependency 'ConciseKit', '~> 0.1.2'
or
- Copy files under
src/
to your project.
#import "ConciseKit.h"
$ class
Method Swizzling
[$ 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]]
Path
[$ 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
waitUntil
Useful when writing tests for asynchronous tasks. Default timeout is 10 seconds, checking is done every 0.1 seconds.
[$ waitUntil:^{ return (BOOL)(someConditionIsMet == YES) }] [$ waitUntil:^{ return (BOOL)(someConditionIsMet == YES) } timeOut:10.0] [$ waitUntil:^{ return (BOOL)(someConditionIsMet == YES) } timeOut:10.0 interval:0.1]
Singleton
Creating Singletons
@interface Foo - (id)initSingleton; // <= add these to the interface + (Foo *)sharedFoo; // <= where Foo is the class name @end @implementation Foo $singleton(Foo); // => makes Foo a singleton class - (id)initSingleton { foo = 1; // do initialization in -initSingleton method bar = 2; return self; } @end
Using Singletons
$shared(Foo) // => returns the shared instance /* or */ [Foo sharedFoo]
