SSAppURLs本地设备 App 检测

SSAppURLs 可以根据 URL scheme 来检测本地设备是否装有某个 App，并且可以打开某个 App，可以传递参数。比如打开 Safari 或者 Chrome 浏览器，可以传递要打开的网址。

示例代码：

#import <UIApplication+SSAppURLs.h>



// Does the current device have skype installed?

BOOL deviceSupportsSkype = [[UIApplication sharedApplication] 

                             canOpenAppType:SSAppURLTypeSkype];



// If so, let's make a call!

if( deviceSupportsSkype )

  [[UIApplication sharedApplication] openAppType:SSAppURLTypeSkype 

                                       withValue:@"415-555-1212"];



// Does the current device have Chrome installed?

BOOL deviceHasChrome = [[UIApplication sharedApplication] 

                        canOpenAppType:SSAppURLTypeChromeHTTP];



// If so, open a website in chrome!

if( deviceHasChrome )

    [[UIApplication sharedApplication] openAppType:SSAppURLTypeChromeHTTP 

                                         withValue:@"http://www.splinesoft.net"];



// Check for an arbitrary scheme type

BOOL deviceHasTelnetApp = [[UIApplication sharedApplication] 

                           canOpenAppWithScheme:@"telnet"];



// Let's play NANVAENT!

if( deviceHasTelnetApp )

    [[UIApplication sharedApplication] openAppWithScheme:@"telnet"

                                               withValue:@"nanvaent.org:23"];
