APP间跳转-传值

第一步:

//在要跳转页面的触发跳转方法中写入跳转路径

//格式:[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"要跳转到的应用名称://"]];

//点击跳转到应用

//[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"Second://"]];

//创建路径

NSString *urlString = [NSStrings tringWithFormat:@"Second://appid=%d&appName=应用名称",arc4random()];

//编码(存在中文需要编码)

urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

//添加路径

NSURL*url = [NSURL URLWithString:urlString];

//创建APP

UIApplication *app = [UIApplication sharedApplication];

//拉入白名单

if([app canOpenURL:url]) {

[app openURL:url];

}

//在info.plist中配置LSApplicationQueriesSchemes  type:array

//在下一级的value中填写Second(要跳转到的APP名称)

设置

第二步:

//在要跳转到的APP中设置自己的URL路径

//identifier可随意写

//URL Schemes要写入该APP的名称

设置

//在该应用的AppDelegate中.导入接收值的控制器,对其实例变量,进行操作

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {

//把上个应用跳转过来的一些信息显示到lable上

_rootViewController = (ViewController *)self.window.rootViewController;

return YES;

}

//接收值的方法

- (BOOL)application:(UIApplication*)app openURL:(NSURL*)url options:(NSDictionary *)options {

//Second://appid=%d&appName=应用名称会接收到全部字符串不好处理

//NSString *urlString = url.absoluteString;

//appid=%d&appName=应用名称

NSString *para = url.host;

//对接收到的字符串进行拆分

NSArray *array = [para componentsSeparatedByString:@"&"];

//再拆分并接收

NSString *appID = [[[array firstObject] componentsSeparatedByString:@"="] lastObject];

//再拆分并接收

NSString *appName = [[[array lastObject] componentsSeparatedByString:@"="] lastObject];

//接收并显示

_rootViewController.messageLabel.text= [NSString stringWithFormat:@"appID:%@ \nappName:%@",appID,appName];

return YES;
