前言：
1.告诉别人怎么跳到自己这边（设置schemes）
2.告诉自己可以跳转到那个人那边(ios9之后 才有这个 设置白名单)
3.自己发出跳转
4.别人接受跳转消息
背景：例子以两个app__ schemesA schemesB 配置完成 两个app在测试机运行起来
告诉别人怎么跳到自己这边（设置schemes）
schemesA
SchemesA 设置URL Schemes
schemesB
SchemesB 设置URL Schemes
告诉自己可以跳转到那个人那边(ios9之后 才有这个 设置白名单 LSApplicationQueriesSchemes) 配合canOpenURL:使用
info.plist 进行配置
SchemesA 粘贴进info.plist
<key>LSApplicationQueriesSchemes</key>
<array>
<string>SchemesA</string>
</array>
SchemesB 粘贴进info.plist
<key>LSApplicationQueriesSchemes</key>
<array>
<string>SchemesB</string>
</array>
SchemesA 发出跳转
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event {
//有参数 跳转到SchemeB
NSString *paramStr = [NSString stringWithFormat:@"SchemesB://username=%@/password=%@",@"username-schemesB",@"password-schemesB"];
NSURL *schemesUrl = [NSURL URLWithString:[paramStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
#ifdef __IPHONE_10_0 //ios10及以后
if ([[UIApplication sharedApplication] canOpenURL:schemesUrl]) {
[[UIApplication sharedApplication] openURL:schemesUrl options:@{UIApplicationOpenURLOptionUniversalLinksOnly : @NO} completionHandler:nil];
//NO 跳转 YES 不跳转
}
#else
if ([[UIApplication sharedApplication] canOpenURL:schemesUrl]) {
[[UIApplication sharedApplication] openURL:schemesUrl];
}
#endif
}
//如果不设置白名单 canOpenURL: 通过这个方法 就找不到对应的app
//但是直接进行调用 openURL: 不先判断 还是可以跳转到对应app
SchemesB 接受跳转消息
状态一：SchemesB 杀死状态 重新启动 会调用下面方法
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
if (launchOptions && launchOptions.count) {
NSString *schemesUrlStr = [launchOptions.allValues.lastObject absoluteString];
//获取URL中的参数
[self getUsernameAndPasswordWithSchemesUrlStr:schemesUrlStr];
}
return YES;
}
//截取username password 自定义
- (void)getUsernameAndPasswordWithSchemesUrlStr:(NSString *)schemesUrlStr {
ViewController *vc = (ViewController *)self.window.rootViewController;
NSString *resultStr = [schemesUrlStr stringByReplacingOccurrencesOfString:@"SchemesB://" withString:@""];
NSArray *arrStr = [resultStr componentsSeparatedByString:@"/"];
//username
NSArray *usernameArr = [arrStr[0] componentsSeparatedByString:@"="];
vc.username = usernameArr.lastObject;
//password
NSArray *passwordArr = [arrStr[1] componentsSeparatedByString:@"="];
vc.password = passwordArr.lastObject;
}
状态二：SchemesB 后台运行 会调用下面方法
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options {
NSString *schemesUrlStr = [url absoluteString];
[self getUsernameAndPasswordWithSchemesUrlStr:schemesUrlStr];
return NO;
}
//截取username password 自定义
- (void)getUsernameAndPasswordWithSchemesUrlStr:(NSString *)schemesUrlStr {
ViewController *vc = (ViewController *)self.window.rootViewController;
NSString *resultStr = [schemesUrlStr stringByReplacingOccurrencesOfString:@"SchemesB://" withString:@""];
NSArray *arrStr = [resultStr componentsSeparatedByString:@"/"];
//username
NSArray *usernameArr = [arrStr[0] componentsSeparatedByString:@"="];
vc.username = usernameArr.lastObject;
//password
NSArray *passwordArr = [arrStr[1] componentsSeparatedByString:@"="];
vc.password = passwordArr.lastObject;
}
