昨天上QQ玩QQ步數(shù)的時(shí)候發(fā)現(xiàn)很多小伙伴的步數(shù)高的嚇人,而我僅僅可憐的三位數(shù),于是我就想我怎么能把這個(gè)步數(shù)刷刷,這樣我就能占領(lǐng)整個(gè)QQ封面了--是時(shí)候裝一波逼了??,這不僅僅可以裝逼,還可以做公益,大家應(yīng)該都有玩過捐步吧,那可都是money啊,為了公益事業(yè),我想這個(gè)應(yīng)用必須得寫了!!!!!

用過蘋果機(jī)都知道,蘋果有個(gè)健康應(yīng)用,其實(shí)第三方的應(yīng)用都是從這里拿的步行數(shù)據(jù),當(dāng)然,不僅僅是步數(shù)數(shù)據(jù),還有很多,以下都算

怎么才能修改步數(shù)呢
答:HealthKit
什么是HealthKit
簡(jiǎn)單的說,HealthKit就是iOS8 以后出現(xiàn)的,蘋果用來生成,存儲(chǔ),查詢各種健康數(shù)據(jù)的一個(gè)API,包括iPhone本身創(chuàng)建的健身數(shù)據(jù),或者第三方app創(chuàng)建的健康數(shù)據(jù),都可以通過這個(gè)API進(jìn)行讀取和查詢.也可以把HealthKit看成iPhone的健康數(shù)據(jù)的一個(gè)統(tǒng)一的數(shù)據(jù)庫(kù),同一個(gè)手機(jī)上的不用app的健康數(shù)據(jù)的讀取都是直接面向healthKit,由HealthKit統(tǒng)一管理,來實(shí)現(xiàn)iOS上不同應(yīng)用之間的健康數(shù)據(jù)的交互.微信(包括qq或者其他第三方app)上的運(yùn)動(dòng)步數(shù),本質(zhì)上也是通過HealthKit來讀取的,所以,我們只需要新建一個(gè)app(當(dāng)然,我這里只做開發(fā)環(huán)境),請(qǐng)求對(duì)HealthKit數(shù)據(jù)的寫入權(quán)限,添加運(yùn)動(dòng)步數(shù)后,(qq或者其他第三方app)通過HealthKit讀取我們手機(jī)上的健康數(shù)據(jù)中的運(yùn)動(dòng)步數(shù)后,自然讀取后的運(yùn)動(dòng)步數(shù)就可以由我們隨心所欲來修改了.當(dāng)然,healthKit里面包含各種各種的健康數(shù)據(jù),包括步數(shù),睡眠,運(yùn)動(dòng)距離,卡路里,血壓等等.想要查看這些數(shù)據(jù)非常簡(jiǎn)單,打開iPhone里面蘋果自帶的健康應(yīng)用,非常直觀的展示了我們的健康數(shù)據(jù).
怎么用HealthKit
這部分內(nèi)容不打算寫了,其實(shí)沒多少內(nèi)容,這里附上我參考的鏈接:點(diǎn)擊進(jìn)入

為什么寫這篇文章--------->
裝逼算不算呢!1111111當(dāng)然算,除此之外,也算是給小伙伴們一個(gè)思路吧,也為以后入Healthkit坑做好準(zhǔn)備,加油,技術(shù)就是金錢啊,要是錢都是捐給我的話多好啊
