如何將數據保存到項目文件夾？

Question

我從網上下載一個XML文件，並將其保存在folder.With這些代碼

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]; 

類文件夾位於myProject的文件夾。

但Apple沒有這個路徑。我需要說保存我的項目文件夾的Class文件夾中的 xml文件。

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

誰能幫我，我應該說../Class或.Class或./Class？

我在創建documentDirectory時應該說什麼。

嘗試：

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"];
