在<strong><span style="font-size:18px;">目标程序</span></strong>的plist文件里面修改：打开xxxx-info.plist，添加一项URL types打开URL types，将item0的URL identifier修改为URL Schems展开URL Schemes，将item0的内容修改为xxxApp(此为跳转的key:例如key2）<pre name="code" class="objc">在源程序里面需要跳转的地方，添加代码NSURL *myUrl = [NSURL URLWithString:@"xxxApp://abcde"]; //xxxApp为<strong><span style="font-size:18px;">目标</span></strong>App跳转的key, 例如:key2  if([[UIApplication sharedApplication] canOpenURL:myUrl]){      [[UIAppliactioin sharedApplication] openURL:myUrl];  }

若想要获取源程序传递过来的参数, 则需要在源程序中得<span style="font-family: Arial, Helvetica, sans-serif;">plist文件里面做同样地修改, 只是将item0的内容修改为本app的key, 例如key1</span>然后在<span style="font-size: 18px; font-weight: bold; font-family: Arial, Helvetica, sans-serif;">目标程序的appDelegate中实现</span><pre name="code" class="objc">- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{    return YES;}- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{

<pre name="code" class="objc"><span style="font-size: 18px; font-weight: bold; font-family: Arial, Helvetica, sans-serif;"></span><p class="p1"><span class="s1">if</span><span class="s2"> ([[url </span><span class="s3">scheme</span><span class="s2">] </span><span class="s3">isEqualToString</span><span class="s2">:</span>@"key2"<span class="s2">]) {</span></p>

<pre name="code" class="objc"><span style="font-size: 18px; font-weight: bold; font-family: Arial, Helvetica, sans-serif;"></span><p class="p2">        <span class="s3">NSLog</span>(<span class="s4">@"</span><span class="s5">传递过来的参数</span><span class="s4"> = %@"</span>,<span class="s1">self</span>.otherString);      </p>

<pre name="code" class="objc"><span style="font-size: 18px; font-weight: bold; font-family: Arial, Helvetica, sans-serif;"></span><p class="p2">    }</p>
