Question

我可以选择在我的应用中将plist文件上传到iCloud。当应用程序被删除并安装回来时，内容必须保留。这是我一直在尝试的，我没有从iCloud上传/检索任何问题。我从云端获得了作为NSData的plist细节。现在的问题是我已将这些数据写回我的plist已存在。

NSArray *paths           = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES);

NSString *documentsDir   = [paths objectAtIndex:0];
NSString *root          = [documentsDir stringByAppendingPathComponent:@"Receipts.plist"];

我从云中获取了作为NSData的plist内容，在转换为NSString后，这就是我得到的。

我在写回旧内容时发现问题。如何将这些内容写回这个空的plist？

这可能会有所帮助。你的plist是一个数组，所以将数组保存到文件中。

//read from file
NSArray *array = [NSArray arrayWithContentsOfFile:root];
//wirte to file
NSArray *sourceArray = [NSArray arrayWithContentsOfFile:filePath];
BOOL success = [sourceArray writeToFile:root atomically:YES];

用xcode中的现有数据编写plist
