在文档目录中创建多个Plist文件..？ [英] Creating Multiple Plist files in document directory..?

问题描述

我正在开发一个包含5个 plist 文件的应用程序。我想将所有这些文件保存在文档目录中。因为我想动态地向他们添加数据。我正在使用

I am developing an application which includes 5 plist files. I want to save all those files in documents directory. Because I want to add data to them dynamically. I am Creating a plist path using

从 plist中检索数据

NSMutableArray *pathsArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docpath = [pathsArray objectAtIndex:0];
NSString *scorePlistPath = [docpath stringByAppendingPathComponent:@"highScores.plist"];

if (![[NSFileManager defaultManager] fileExistsAtPath:scorePlistPath]) {
    scorePlistPath = [[NSBundle mainBundle] pathForResource:@"highScores" ofType:@"plist"];
}
highScoreArray = [[NSMutableArray alloc]initWithContentsOfFile:scorePlistPath];

将数据写入 plist

scorePlistPath = [docpath stringByAppendingPathComponent:@"highScores.plist"];

[highScoreArray writeToFile:scorePlistPath atomically:YES];

现在我想再添加一个 plists 在文档目录..不在Bundle中。我怎么能这样做？？

Now I want to add one more plists in documents directory.. Not in the Bundle. How can i do that..?

推荐答案

以编程方式无法将文件添加到应用程序包中，因为您没有权限并保存或加载 Documents 文件夹中的文件并不是什么大不了的事：

programatically you cannot add files into the application bundle because you don't have permission and to save or load the files from the Documents folder is not a big deal:

首先，您需要定义文件所在的URL ：

NSString *_filename = @"myOwn.plist";
NSURL *_resourceURL = [[[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject] URLByAppendingPathComponent:_fileName];

然后你可以保存文件：

NSArray *_array = // your array as you defined
[_array writeToURL:_resourceURL atomically:true];

以及任何时候文件可以再次加载：

NSData *_plistData = [NSData dataWithContentsOfFile:[_resourceURL path]];
NSArray *_loadedArray = [NSPropertyListSerialization propertyListFromData:_plistData mutabilityOption:NSPropertyListImmutable format:nil errorDescription:nil]; // the option or the format parameter might be set for your special wishes, so check the documentation, please

和violá，已经完成。
