IOS程序中打开自己的程序,测试机器中是否装了自己的程序(openURL:,canOpenURL:)

openURL能帮助你运行Maps，SMS，Browser,Phone甚至其他的应用程序。

openURL的使用方法： 

[[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:myURLString]];

自己定义URL，方法如下： 

打开info.plist，添加一项URL types

展开URL types，再展开Item1，将Item1下的URL identifier修改为URL Scheme
展开URL Scheme，将Item1的内容修改为myapp

或者:

（增加一下此段设置）
<key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleURLSchemes</key>
            <array>
                <string>myapp</string>
            </array>
            <key>CFBundleURLName</key>
            <string>com.yourcompany.appName</string>
        </dict>
    </array>

其他程序可通过myapp://访问此自定义URL

可通过[[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"myapp://com.yourcompany.appName"]];

来判断用户机器中是否安装了该程序

最近接触到程序内打开自己，通过第三方控件来调用本身程序：

通过- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url

可以通过处理url来获取信息扫行相应操作。

 

 

01	-(IBAction)openMaps {//打开地图

02	// Where is Apple on the map anyway?

03	NSString* addressText = @”1 Infinite Loop, Cupertino, CA 95014″;

04	// URL encode the spaces

05	addressText =  [addressText stringByAddingPercentEscapesUsingEncoding: NSASCIIStringEncoding];

06	NSString* urlText = [NSString stringWithFormat:@"http://maps.google.com/maps?q=%@", addressText];

07	// lets throw this text on the log so we can view the url in the event we have an issue

08	NSLog(urlText);

09	[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlText]];
