我原本以为这个是不太可能的，之前用的也都是通过 URL Schemes来跳转 ，人家的 Bundle ID也不会给你，可是最近有个项目就是这样的需求，找了很长时间，都是这三句话
ClassLSApplicationWorkspace_class =objc_getClass("LSApplicationWorkspace");
NSObject* workspace = [LSApplicationWorkspace_classperformSelector:@selector(defaultWorkspace)];
BOOLisopen = [workspaceperformSelector:@selector(openApplicationWithBundleID:)withObject:@"第三方app的Bundle ID"];
后面没有了，琢磨了半天，将下面的代码补齐(我是将提示框封装了一下)
if(isopen ==YES) {
NSLog(@"打开了");
}else{
NSLog(@"没有app");
[selfaddActionTotitle:@"提示"withMessage:@"您的手机上没有安装 x x x APP，是否前往下载?"withActionTitle:@"确定"withActionTitle2:@"取消"viewController:selfblock:^(BOOLisdelea) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"https://itunes.apple.com/us/app/id第三方APP的id?mt=8"]];
}];
}
#pragma mark 提示框
-(void)addActionTotitle:(NSString*)title withMessage:(NSString*)massage withActionTitle:(NSString*)actionTitle withActionTitle2:(NSString*)actionTitle2 viewController:(UIViewController*)vc block:(void(^)(BOOLisdelea))isok{
UIAlertController *alertController=[UIAlertController alertControllerWithTitle:title message:massage preferredStyle:( UIAlertControllerStyleAlert)];
UIAlertAction *action=[UIAlertAction actionWithTitle:actionTitle style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {
isok(YES);
}];
UIAlertAction *action2=[UIAlertAction actionWithTitle:actionTitle2 style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {
}];
[alertControlleraddAction:action];
[alertControlleraddAction:action2];
[vcpresentViewController:alertController animated:YES completion:nil];
}
