2. 應(yīng)用間相互跳轉(zhuǎn)簡(jiǎn)介
在iOS開發(fā)的過程中趟大，我們經(jīng)常會(huì)遇到需要從一個(gè)應(yīng)用程序A跳轉(zhuǎn)到另一個(gè)應(yīng)用程序B的場(chǎng)景。這就需要我們掌握iOS應(yīng)用程序之間的相互跳轉(zhuǎn)知識(shí)逢防。iOS9之后膀息，應(yīng)用間跳轉(zhuǎn)需要在Info.plsit中設(shè)置白名單芦劣。以‘LSApplicationQueriesSchemes’為Key值，對(duì)應(yīng)數(shù)組value中添加白名單應(yīng)用的URL Schemes即可霍殴。若未設(shè)置白名單涮帘，會(huì)報(bào)錯(cuò)，值得我們注意贬芥。
原理：通過設(shè)置跳轉(zhuǎn)到應(yīng)用B的URL Schemes（自定義的協(xié)議頭）吐辙，應(yīng)用B將其自身“綁定”到一個(gè)自定義URL Schemes上，就可以從應(yīng)用A中利用應(yīng)用B的URL Schemes啟動(dòng)應(yīng)用B了蘸劈。
設(shè)置App-B的URL Schemes
選擇項(xiàng)目App-B -> TARGETS -> Info -> URL Types -> URL Schemes昏苏，設(shè)置App-B的URL Schemes為AppB。
// 1.獲取應(yīng)用程序App-B的URL Scheme
NSURL?*appBUrl?=?[NSURL?URLWithString:@"AppB://"];
//?2.判斷手機(jī)中是否安裝了對(duì)應(yīng)程序
if?([[UIApplication?sharedApplication]?canOpenURL:appBUrl])?{
//?3.?打開應(yīng)用程序App-B
[[UIApplication?sharedApplication]?openURL:appBUrl];
}?else?{
NSLog(@"沒有安裝");
}
