addSkipBackupAttributeToItemAtURL-> NSString参数? [英] addSkipBackupAttributeToItemAtURL -> NSString parameter?

问题描述

为了遵循数据存储准则，我必须使用以下方法添加一个标志，说不要将其备份到iCloud.但是，此处的参数用于NSURL.我需要像这样在一行中传递一个NSString

In order to follow the Data Storage Guidelines I must use the below method to add a flag to say to not back it up to iCloud. However, the parameter here is for a NSURL. I need to pass it a NSString like from a line like so

return [[self offlineQueuePath] stringByAppendingPathComponent:@"SHKOfflineQueue.plist"];

这是采用URL的方法.

Here is the method that takes in a URL.

    - (BOOL)addSkipBackupAttributeToItemAtURL:(NSURL *)URL
{
    if (&NSURLIsExcludedFromBackupKey == nil) { // iOS <= 5.0.1
        const char* filePath = [[URL path] fileSystemRepresentation];

        const char* attrName = "com.apple.MobileBackup";
        u_int8_t attrValue = 1;

        int result = setxattr(filePath, attrName, &attrValue, sizeof(attrValue), 0, 0);
        return result == 0;
    } else { // iOS >= 5.1
        NSError *error = nil;
        [URL setResourceValue:[NSNumber numberWithBool:YES] forKey:NSURLIsExcludedFromBackupKey error:&error];
        return error == nil;
    }
}

无论如何，当我将NSString作为参数时，我将如何修改上述方法以实现相同的目的?

谢谢！

推荐答案

您不需要修改方法.将您的字符串转换为URL.

You don't need to modify the method. Convert your string to URL.

NSURL *url = [NSURL URLWithString:@"your string"];
