的NSDictionary到顯示每個項目

Question

我有以下代碼：

for (int i = 1; i<=count; i++) { 

    NSString *j = [[NSString alloc] initWithFormat:@"%d",i ]; 

    NSArray *fields = [[NSArray alloc] initWithObjects: 
         @"name",nil]; 
    //@"title",@"mobile",@"email",@"website" 
    [requestExecute setMethod:@"execute" withObjects:[NSArray arrayWithObjects: 
                  @"testdb",userid,@"admin",@"res.partner.contact",@"read",j,fields,nil]]; 
    NSDictionary *records=[self executeXMLRPCRequest:requestExecute]; 

NSLog(@"\nKey : %@ value : \n",records);

這會逐一打印每條記錄。現在我想逐一記錄這個記錄中的每個字段。任何幫助，將不勝感激。

Answer 1

我不確定requestExecute會做什麼，但是如果您想循環遍歷NSDictionary中的所有值，您可以使用[records allKeys]，它將返回字典中所有鍵的NSArray。

Answer 2

的Objective-C 2.0支持很方便快速列舉語法收藏...

for(NSString *aKey in records){ 
    NSLog(@"%@", [[records valueForKey:aKey] description]); 
}
