ios指定目录不进行icloud检测

标签：ios开发   icloud检测   

时间真的是过得飞快，一周过去，现在来总结想想，好像都没有什么收获。这是一件让人非常恼怒的事情，明明每天都加班，明明连周六都在上班，钱没多拿，经验和知识却没有增加。上一周主要是在同事做过的模块里添加新功能，由于同事去做新的游戏，原先的应用完全由我来维护。同事的代码不错，采用MVC结构，结构剥离的相当明确，C层采用一个驱动，驱动里面嵌套了一个状态机。M数据采用装饰者模式嵌入C 层，利用事件响应机制来实现C层与V层的通讯。比较有价值的应该是他实现状态机的过程，可惜我要赶项目，而且当时编译原理也没学透彻，所以有点囫囵吞枣了。再者就是看同事定义的与后台的协议了，我们现在的做的是德州扑克的回放，状态比较多。着实是花了一些时间去看，代码是如何读取数据的。

当然这不是一篇抱怨的文章，虽然我老是抱怨这抱怨那的，其实我也挺讨厌那样的自己，只是控制不住罢了。比较有意义的一点可能是如何绕过ios的icloud审核。我们的应用是一个弱联网的，为了节省用户流量因此在app里面预存了一些数据。在程序第一次运行时，将数据从程序包拷贝到document目录。由于这个原因，app被app store拒绝过一次，提示程序未做任何操作，但是icloud多了一些数据。

绕过的方法如下:

- (BOOL)addSkipBackupAttributeToItemAtURLHigh:(NSURL *)URL
{
//    5.1 +
    assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]);
    
    NSError *error = nil;
    BOOL success = [URL setResourceValue: [NSNumber numberWithBool: YES]
                                  forKey: NSURLIsExcludedFromBackupKey error: &error];
    if(!success){
        NSLog(@"Error excluding %@ from backup %@", [URL lastPathComponent], error);
    }
    return success;
}

- (BOOL)addSkipBackupAttributeToItemAtURLLow:(NSURL *)URL

{
//    5.0.1:
    assert([[NSFileManager defaultManager] fileExistsAtPath: [URL path]]);
    
    
    
    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;
    
}
