How can I detect if user has an app, like echofon or twitter for mac or if user has pages, or textmate? Any suggestions?

推荐答案

使用NSWorkspace的fullPathForApplication:获取应用程序的分发包路径.如果该方法返回nil，则说明未安装该应用程序.例如:

Use NSWorkspace's fullPathForApplication: to get an application's bundle path. If that method returns nil, the app is not installed. For example:

NSString *path = [[NSWorkspace sharedWorkspace] fullPathForApplication:@"Twitter"];

BOOL isTwitterInstalled = (nil != path);

URLForApplicationWithBundleIdentifier是您可以使用的另一种方法.

URLForApplicationWithBundleIdentifier is another method you may use.
