iOS应用跳转问题之：应用跳转

简单明了，打开第三方APP代码：

    NSURL *url = [NSURLURLWithString:@"alipay://"];

    if(![[UIApplicationsharedApplication]canOpenURL:url]){

        [[UIApplicationsharedApplication]openURL:[NSURLURLWithString:@"https://www.alipay.com"]];

    } else {

        [[UIApplicationsharedApplication]openURL:url];

    }
