本文介绍了我如何从Swift的字典获得密钥的价值?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我早早起来快鸟。我有一个字典。我想得到我的键的value.Object的关键方法不适用于我。有人可以帮助我吗?这是我的字典; / p>
var companies = [AAPL:Apple Inc,GOOG:Google Inc,AMZN Amazon.com,Inc,FB:Facebook Inc]
在company.key {
println(companies.objectForKey(AAPL )
}
解决方案
使用这种方法,您将看到密钥和值。
var companies = [AAPL:Apple Inc,GOOG :Google Inc,AMZN:Amazon.com,Inc,FB:Facebook Inc]
(公司中的(key,value)){
println (\(key) - > \(value))
}
或者如果您只想要的值:
在...的价值.values.array {
println(\\ \\(价值))
}
访问字典:
println(companies [AAPL])

I am early bird in swift. I have a dictionary.I want to get my key's value.Object for key method is not worked for me.Can anybody help me please?
This is my dictionary;
var companies = ["AAPL" : "Apple Inc", "GOOG" : "Google Inc", "AMZN" : "Amazon.com, Inc", "FB" : "Facebook Inc"] for (name) in companies.key { println(companies.objectForKey("AAPL")) }
解决方案With this method you see the key and the value.
var companies = ["AAPL" : "Apple Inc", "GOOG" : "Google Inc", "AMZN" : "Amazon.com, Inc", "FB" : "Facebook Inc"] for (key, value) in companies { println("\(key) -> \(value)") }
Or if you only want the values:
for value in companies.values.array { println("\(value)") }
One value with direct access on the dictionary:
println(companies["AAPL"])
