如何启动应用程序，并使它可以使用Cocoa api？ [英] How to launch application and bring it to front using Cocoa api?

问题描述

我是一个新的可可程序，我找不到办法做以下：

• 开始一个特殊的


• 稍后提出该应用程序我已经开始成为前台进程

/ ul>



根据我在Carbon API中发现的，我应该使用的调用是launchApplication（）和setFrontProcess（）。





但是如何在Cocoa中做到这一点呢？也就是说启动它，获得PID，将该PID设置为前进程。我尝试google的例子，找不到任何东西...





如果你有任何人可以提供一个简单的样品，将是真棒：）





提前感谢。

解决方案

启动应用程序：

  [[NSWorkspace sharedWorkspace] launchApplication：@/ Applications / Safari.app]; 
  

要激活应用程序：

  NSRunningApplication * app = [NSRunningApplication 
 runningApplicationWithProcessIdentifier：PID]; 
 [app activateWithOptions：NSApplicationActivateAllWindows]; 
 //或
 NSArray * apps = [NSRunningApplication 
 runningApplicationsWithBundleIdentifier：@com.bla.blah]; 
 [（NSRunningApplication *）[apps objectAtIndex：0] 
 activateWithOptions：NSApplicationActivateAllWindows]; 
  




I'm very new to a cocoa programming and I can't find the way to do the following:

• Start a particular application by name
• Do some work
• Later bring that application I've started to be the front process

From what I've found in Carbon API it looks like the calls i should use are launchApplication() and setFrontProcess().

But how to do this in Cocoa? I.e. launch it, get PID, set that PID to be a front process. I tried to google for examples and find nothing...

If any of you can provide a minimalistic sample that would be awesome :)

Thanks in advance.

解决方案

To launch an application :

[[NSWorkspace sharedWorkspace] launchApplication:@"/Applications/Safari.app"];

To activate an app :

NSRunningApplication* app = [NSRunningApplication
                             runningApplicationWithProcessIdentifier: PID];
[app activateWithOptions: NSApplicationActivateAllWindows];
// or
NSArray* apps = [NSRunningApplication
                 runningApplicationsWithBundleIdentifier:@"com.bla.blah"];
[(NSRunningApplication*)[apps objectAtIndex:0]
 activateWithOptions: NSApplicationActivateAllWindows];
