iPhone：performSelector with BOOL参数？ [英] iPhone: performSelector with BOOL parameter?

问题描述

有没有办法在选择器中发送BOOL？

Is there any way to send BOOL in selector ?

[self performSelector:@selector(doSomething:) withObject:YES afterDelay:1.5];

或者我应该使用NSInvocation？有人可以写样品吗？

Or I should use NSInvocation ? Could somebody write a sample please ?

推荐答案

你可以用NSNumber来包装bools类型：

you can use NSNumber to wrap bools types:

BOOL myBool = YES;
NSNumber *passedValue = [NSNumber numberWithBool:myBool];
[self performSelector:@selector(doSomething:) withObject:passedValue afterDelay:1.5];

并且在选择器中，要获得bool值，请使用：

and in the selector, to get the bool value, you use:

BOOL value = [recievedObject boolValue];
