If I have a Swift struct like this:
struct ViewBox {
let pointer: UnsafeMutablePointer<UIView>
init() {
pointer = UnsafeMutablePointer<UIView>.alloc(1)
}
}
how should I ensure, that the pointer is properly deallocated, when the struct is deallocated? I can't use deinit
or dealloc
methods for Swift structs.
Or I don't have to care and it's happening automatically?
You could wrap the pointer in a class. Something like this:
struct ViewBox {
class WrappedPointer() {
let pointer: UnsafeMutablePointer<UIView>
init() {
pointer = UnsafeMutablePointer<UIView>.alloc(1)
}
deinit {
pointer.dealloc(1)
}
}
let wrappedPointer = WrappedPointer()
}
