xcode - 设置在共享工作区 Mac OSX 中启动的应用程序的框架位置

Question

我正在从我的应用程序中打开系统首选项应用程序。我还想设置应用程序框架，使其与应用程序的左侧对齐。问题是我不知道如何访问应用程序框架属性，或在特定点启动它。

我使用 NSWorkspace 来启动它，然后获取 NSRunningApplication 的一个实例，我希望它可以用来操作窗口。

-(void)openPreferencesAndSetFrame;
{
    @try {
        BOOL success = [[NSWorkspace sharedWorkspace] openFile:@"/System/Library/PreferencePanes/Localization.prefPane"];
        if (success == YES)
        {
            NSArray *appArray = [NSRunningApplication runningApplicationsWithBundleIdentifier:@"com.apple.systempreferences"];
            if ([appArray count] > 0)
            {
                NSRunningApplication *sysPrefApp = [appArray objectAtIndex:0];
                //set frame here
            }
        }         
    } @catch (NSException *exception) {
        NSLog(@"%@", [exception description]);
    }
}

经过一番研究、尝试和错误，我找到了解决方案。正如前面提到的，AppleScript 能够完成这项工作。

-(void)openPreferencesAndSetFrame;
{
    @try {
        NSAppleEventDescriptor *theResult;
        NSDictionary *errorInfo;
        float posX = 100;
        float posY = 200;

        NSString *sourceStr = [NSString stringWithFormat:@"ignoring application responses\r\n tell application \"System Preferences\"\r\n activate\r\n end tell\r\n tell application \"System Events\"\r\n tell process \"System Preferences\"\r\n set position of window 1 to {%f, %f}\r\n end tell\r\n end tell\r\n end ignoring\r\n", posX, posY];
        NSAppleScript *theScript = [[NSAppleScript alloc] initWithSource:sourceStr];

        theResult = [theScript executeAndReturnError:&errorInfo];
        if (nil == theResult ) {        
            NSString *err = [NSString stringWithFormat:
                         @"Error %@ occured call: %@",
                         [errorInfo objectForKey:NSAppleScriptErrorNumber],
                         [errorInfo objectForKey:NSAppleScriptErrorBriefMessage]];

            NSRunAlertPanel(@"AttachAScript Error", err, @"ok", nil, nil);
        }                
    } @catch (NSException *exception) {
        NSLog(@"%@", [exception description]);
    }
}
