如何将数据保存到项目文件夹？

Question

我从网上下载一个XML文件，并将其保存在folder.With这些代码

NSURL *goo = [[NSURL alloc]initWithString:@"......xml"]; 
NSData *data = [[NSData alloc] initWithContentsOfURL:goo]; 
NSString *xml = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
NSString *documentsDirectory = @"/Users/MacBook/Desktop/Bebegim_Icin_Yarisiyorum/Milyoner/Class"; 
NSString *xmlFilePath = [documentsDirectory stringByAppendingPathComponent:@"qpack1.xml"]; 
[xml writeToFile:xmlFilePath atomically:YES encoding:NSUTF8StringEncoding error:nil]; 

类文件夹位于myProject的文件夹。

但Apple没有这个路径。我需要说保存我的项目文件夹的Class文件夹中的 xml文件。

/Users/MacBook/Desktop/Bebegim_Icin_Yarisiyorum/Milyoner/Class 

谁能帮我，我应该说../Class或.Class或./Class？

我在创建documentDirectory时应该说什么。

尝试：

NSString *documentsDirectory = [NSHomeDirectory()stringByAppendingPathComponent:@"Documents/qpack2.xml"]; 

或者：

NSArray *pathArray = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) 
NSString *docsPAth = [pathArray objectAtIndex:0]; 
NSString *documentsDirectory = [documentsDirectory stringByAppendingPathComponent:@"qpack2.xml"];
