Swift-字典

// 定义并实例化字典
var dict = [String:AnyObject]()
dict["name"] = "zhangsan"
dict["age"] = 18
print(dict)
// 设置相同key,之前的数值会被覆盖
dict["name"] = "lisi"
print(dict)
// 删除某一个key
dict.removeValueForKey("age")
print(dict)
dict("title") = "manager"
print(dict)
// 遍历字典(k,v可以随便用)
for(k,v) in dict{
print("\(k) -- \(v)")
}
// 合并字典
var dict2 = ["name":"wangwu","age": 18,"title":"boss"]
for (k,v) in dict2{
dict.updateValue(v,forKey:k)
}
