显示NSArray中的每个项目

Question

我有以下代码：

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);
}

输出看起来像

        title = "M.";  
        website = "www.hudson.com";  
    }  
)  

这将逐个打印每条记录。现在，我想逐一获取此记录中的每个字段。

您可以尝试使用此键循环每个键：

for(NSString *key in records) {
   //do something with key or [records objectForKey:key];
}
