Question

有没有办法在iCloud上复制文件（db.Sqlite）而不必删除本地文件？我有这个代码：

NSLog(@"File does not exist in cloud");
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:@"db.sqlite"];
    NSURL *fromURL = [NSURL URLWithString:writableDBPath];
    BOOL success = [fileManager  setUbiquitous:YES itemAtURL:fromURL destinationURL:ubiquityURL error:&error];
    if (success)
    {
        NSLog(@"copied to icloud");
    }

该文件已复制到iCloud，但已从本地删除，但我也希望您留在本地。它是如何工作的？

您可以使用copyItemAtURL:toURL:error:。像这样：

NSLog(@"File does not exist in cloud");
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *writableDBPath = [documentsDirectory stringByAppendingPathComponent:@"db.sqlite"];
    NSURL *fromURL = [NSURL URLWithString:writableDBPath];
    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
           BOOL success =  [fileManager copyItemAtURL:fromURL toURL:ubiquityURL error:&error];
    if (success)
    {
        NSLog(@"copied to icloud");
    }
    });

将文件复制到iCloud，而不必删除本地文件
