我可以通過編程創建plist嗎？使用json對象

Question

如何在iPhone中使用Plist文件創建父和子我有一個json對象。這個對象來自web服務。 我想嘗試使用plist文件創建一個樹結構。

我可以通過編程創建plist文件嗎？使用json對象

  { 
      "component":[ 
      { 
       "id":1006, 
       "name":"Image test 2",

是爲什麼不只是在NSDictionary中獲取JSON對象並將其寫入由您定義的路徑的文件。

由於json是NSDictionary對象。

NSString *filePath=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents/myfile.plist"]; 
[dictionary writeToFile:filePath atomically:YES]; 

粘貼下面的代碼到viewDidLoad中，你會到這裏來定義你的plist文件路徑時

NSString *jsonString=@"{\"component\":[ { \"id\":1006, \"name\":\"Image test 2\", \"child\":[ { \"id\":1101, \"name\":\"component score mcq\" }, { \"id\":1105, \"name\":\"component we score\" }, { \"id\":1095, \"name\":\"a\" }, { \"id\":1103, \"name\":\"component scq score\" }, { \"id\":1134, \"name\":\"Hi this is my first blog from lesson\" }, { \"id\":1106, \"name\":\"abc\" }, { \"id\":1102, \"name\":\"component fitb score\" }, { \"id\":1096, \"name\":\"testkrupsvideo\" }, { \"id\":1104, \"name\":\"component either score\" }, { \"id\":1099, \"name\":\"krupsblog updated\" }, { \"id\":1224, \"name\":\"krupsforum updated\" }, { \"id\":1127, \"name\":\"reading parent topic test\" }, { \"id\":1093, \"name\":\"abc\" }, { \"id\":1128, \"name\":\"ankit parent topic\" }, { \"id\":1129, \"name\":\"test topic for component\", \"child\":[ { \"id\":1228, \"name\":\"krupsud\" }, { \"id\":1253, \"name\":\"06-12-2012 we updated\" }, { \"id\":1130, \"name\":\"topic reading\" }, { \"id\":1251, \"name\":\"06-12-2012 fitb\" }, { \"id\":1225, \"name\":\"krupsvideo updated\" }, { \"id\":1249, \"name\":\"06-12-2012 mcq\" }, { \"id\":1250, \"name\":\"06-12-2012 scq\" }, { \"id\":1226, \"name\":\"krupsaudio updated\" }, { \"id\":1227, \"name\":\"krupsflash updated\" }, { \"id\":1252, \"name\":\"06-12-2012 eo\" } ] }, { \"id\":1124, \"name\":\"First dlr wiki for positive test\", \"child\":[ { \"id\":1125, \"name\":\"Component wiki\" } ] }, { \"id\":1126, \"name\":\"bhushan reading dlr\" } ] } ] }"; 

NSData* data = [jsonString dataUsingEncoding:NSUTF8StringEncoding]; 

NSDictionary *dictionary=[[NSDictionary alloc] initWithDictionary:[NSJSONSerialization JSONObjectWithData: data options: NSJSONReadingMutableContainers error: nil]]; 

NSString *filePath=[NSHomeDirectory() stringByAppendingPathComponent:@"Documents/myfile.plist"]; 
[dictionary writeToFile:filePath atomically:YES];
