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

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。

Answer 1

Objective-C 2.0支持非常方便的快速枚举语法集合......

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

Answer 2

我不确定requestExecute是做什么的，但是如果你想循环遍历NSDictionary中的所有值，你可以使用[records allKeys]来返回字典中所有键的NSArray。

NSDictionary显示每个项目
