performSelector may cause a leak because its selector is unknown

Question

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

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

Here\'s what

Answer 1

For posterity's sake, I've decided to throw my hat into the ring :)

Recently I've been seeing more and more restructuring away from the target/selector paradigm, in favor of things such as protocols, blocks, etc. However, there is one drop-in replacement for performSelector that I've used a few times now:

[NSApp sendAction: NSSelectorFromString(@"someMethod") to: _controller from: nil];

These seem to be a clean, ARC-safe, and nearly identical replacement for performSelector without having to much about with objc_msgSend().

Though, I have no idea if there is an analog available on iOS.
