iOS两个应用间的跳转

一.应用FirstApp调到SecondApp

1. SecondApp的设置
   
2. FirstApp的设置
   
3. FirstApp跳转到SecondApp的代码

if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"secondapp://"]]) {        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"secondapp://"]];    }else{        NSLog(@"无法从FirstApp跳转到SecondApp");    }

二.常见错误

• -canOpenURL: failed for URL: “secondapp://” - error: “This app is not allowed to query for scheme secondapp”*

原因：没有对FirstApp的infoPlist进行如下设置

<key>LSApplicationQueriesSchemes</key>    <array>        <string>secondapp</string>    </array>
