在iOS中使用-（单向无效）

[英]use of - (oneway void) in iOS

原文 2011-06-27 11:28:47 6 2 iphone/ objective-c/ oneway

Can anyone send me a sample code to write asynchronus method using "oneway" (oneway void) for iOS. 谁能给我发送示例代码来使用iOS的“单向”（oneway void）编写异步方法。 So that it will not block the calling thread until the method returns. 这样在方法返回之前它不会阻塞调用线程。

Have a look at the -performSelectorInBackground:withObject: method on NSObject . 看看NSObject上的-performSelectorInBackground:withObject:方法。 I also recommend Apples Threading Programming Guide for some best practices when using asynchronous methods. 我还建议使用Apples 线程编程指南，以获得使用异步方法时的一些最佳实践。
