android - 无法取消 Corona 中的组转换以避免内存泄漏

Question

我的代码看起来像这样:

local myTransition
local myGroup = display.newGroup()

-- Fill group with all sorts of stuff

-- Create the transition
myTransition = transition.to(myGroup, {alpha = 1})

-- Get rid of the transition
if myTransition ~= nil then
    transition.cancel(myTransition)
end

myTransition = nil

当我尝试时，我得到的是零值:

Runtime error
?:0: attempt to index a nil value
stack traceback:
[C]:?
?: in function 'cancel'

如果我想取消任何其他对象的任何其他过渡，效果很好。当我尝试进行组转换时，它失败了。有什么想法吗？

Answer 1

尝试将转换称为:

myTransition = transition.to(myGroup, {time = 1000, alpha = 1})

和取消为:

if myTransition ~= nil then
    transition.cancel(myTransition)
    myTransition = nil
end

继续编码................ :)
