[英]Do we need to worry about weak self inside methods called from closures
Trivial but looking for confirmation I'm understanding correctly: 琐碎,但正在寻找确认,我正确理解了:
If we have a simple closure as so: 如果我们有一个简单的闭包:
let closure = { [weak self] in
self?.doSomething()
}
Do we need to worry about weak/strong self within the method itself? 我们是否需要担心方法本身内部的弱/强自我?
func doSomething() {
self.classString = "some new string"
// the self in this case will come from the weak self in the closure?
}
The following as I understand is unnecessary even though it'll be called from a closure: 据我了解,以下内容是不必要的,即使会从闭包中调用它:
func doSomething() {
weak var weakSelf = self
weakSelf.classString = "some new string"
}
不,我们不必担心,因为一种方法无法捕获任何东西。
