objective-c - 如何停止 enumerateObjectsUsingBlock Swift

Question

如何停止区 block 枚举？

    myArray.enumerateObjectsUsingBlock( { object, index, stop in
        //how do I stop the enumeration in here??
    })

我知道在 obj-c 中你这样做:

    [myArray enumerateObjectsUsingBlock:^(id *myObject, NSUInteger idx, BOOL *stop) {
        *stop = YES;
    }];

Answer 1

不幸的是，这改变了 Swift 的每个主要版本。这是一个分割:

swift 1

stop.withUnsafePointer { p in p.memory = true }

swift 2

stop.memory = true

swift 3

stop.pointee = true
