使用componentsJoinedByString：方法打印数组

Question

嘿伙计们我正在使用上面的方法：

string = [array componentsJoinedByString:@"\n"];

这会打印出我的数组中的每个obj，但打印出来的是：

{
Selected = 0;
name = "boots";
number = 69;
}
{
Selected = 0;
name = house;
number = 1001;
}
}
Selected = 0;
name = shirt;
number = 1234;
}
{
Selected = 0;
name = Brewski;
number = 4567;
}



 and i just want it to print out:

 Brewski
 Boots...

etc..

数组中的对象似乎是字典。你应该这样做。

[[array valueForKey:@"name"] componentsJoinedByString:@"\n"]
