swift - continue 只允许在循环内

Question

这是不是 Swift 中的一个错误，任何放置在自动释放池中的代码都认为它不在循环中？是否有解决此问题的方法，而不是通过将我的代码分成多个自动释放池来制作困惑的代码？

for (key, value) in dictionary {
    autoreleasepool {
        // Lots of allocation and lots of logic

        continue // Need to continue to the next loop

        // Lots of allocation and lots of logic
    }
}

Answer 1

autoreleasepool 的参数是一个闭包，所以你可以提前返回 来自闭包:

for (key, value) in dictionary {
    autoreleasepool {
        // Lots of allocation and lots of logic

        if someCondition { return } // Need to continue to the next loop

        // Lots of allocation and lots of logic
    }
}
