Jump between ios apps, pass values, and jump between ios apps

Jump between ios apps, pass values, and jump between ios apps
The jump between two apps is achieved through [[UIApplication sharedApplication] openURL: url.

1. First set the url of the first APP

2. Set the url of the second APP.

 

3. Jump

NSString *urlString = [NSString stringWithFormat:@"AppJumpSecond://%@",textField.text];[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];

I will upload textField text here.

The same is true on the second page.

NSString *urlString = [NSString stringWithFormat:@"AppJumpFirst://%@",textField.text];[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];

In this way, you can jump to each other.

4. Process uploaded data

After the textField data is uploaded

-(BOOL) application :( UIApplication *) application openURL :( NSURL *) url sourceApplication :( NSString *) sourceApplication annotation :( id) in the annotation method.

Set attributes in AppDelegate

@ Property (nonatomic, strong) RootViewController * rvc;

Add the didfinishlaunchingwitexceptions Method

self.rvc = [[RootViewController alloc] init];UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:self.rvc];self.window.rootViewController = nc;

Add code block

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{    self.rvc.textField.text = [[url host] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];    return YES;}

This allows textField to display data transmitted from another page.
