iOS 文件剪切

- (void)moveFile
{
    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
    NSString *from = @"/Users/zyg/Desktop/From";
    NSString *to = @"/Users/yzg/Desktop/To";
    
    NSFileManager *mgr = [NSFileManager defaultManager];
    NSArray *subpaths = [mgr subpathsAtPath:from];
    
    dispatch_apply(subpaths.count, queue, ^(size_t index) {
        NSString *subpath = subpaths[index];
        NSString *fromFullpath = [from stringByAppendingPathComponent:subpath];
        NSString *toFullpath = [to stringByAppendingPathComponent:subpath];
        // 剪切
        [mgr moveItemAtPath:fromFullpath toPath:toFullpath error:nil];
        // 或者根据需要
        [mgr moveItemAtURL:XXX toURL:[NSURL fileURLWithPath:XXX] error:nil]
        
        NSLog(@"%@---%@", [NSThread currentThread], subpath);
    });
}

• 注:apply会在子线程也会在主线程中执行
