Apple Demo没有“ performSelector可能会导致泄漏，因为其选择器未知”警告。 有人知道为什么吗？

Question

I'm getting the following warning by the ARC compiler:

"performSelector may cause a leak because its selector is unknown".

Here's what I'm doing:

[_controller performSelector:NSSelectorFromString(@"someMethod")];

But under Apple Demo , they don't have this Warning for the same code. Anyone know why?

That sample is not an ARC project. The warning you cite is the default with ARC projects.
