ios - EKEventStore编程Xcode iOS异步搜索

Question

文档指出:

• (void)enumerateEventsMatchingPredicate:(NSPredicate *)predicate usingBlock:(EKEventSearchCallback)block

This method is synchronous. For asynchronous behavior, run the method on another thread with dispatch_async or NSOperation.

如何使这个异步，句子并没有真正演示它。谁能解释一下吗？

谢谢

要么全部发送:

#include <stdio.h>

int main(int argc, char *argv[]) {
    ...
    dispatch_async(dispatch_get_global_queue(0,0), ^{
        [store enumerateEventsMatchingPredicate:p usingBlock:^(..) {
            //DO IT
        }];
    });
    ...
}

或回调

#include <stdio.h>

int main(int argc, char *argv[]) {
    ...
    [store enumerateEventsMatchingPredicate:p usingBlock:^(..) {
        dispatch_async(dispatch_get_global_queue(0,0), ^{
        //DO IT
        });
    }];

    ...
}
