禁用任务控制，空间，仪表板和任何其他外部过程 [英] Disabling Mission Control, Spaces, Dashboard and any other external process

问题描述

我想知道是否有可能(在短时间内)禁用并重新启用应用程序中的任务控制，空间，曝光，仪表板等应用程序的外部进程，同时仍然允许用户使用我的应用程序?

I was wondering if it was possible to (for a short period of time) disable and re-enable external processes to an application like Mission Control, Spaces, Expose, Dashboard, etc... within an application, while still allowing the user to use my application?

我发现实现此目标的一种方法是使用 NSTask 来禁用带有相应终端命令的进程.例如:

A way of accomplishing this I found was to use NSTask to disable the processes with the corresponding terminal command. For Example:

- (NSString *)runCommandWithBase:(NSString *)base arguments:(NSArray *)arguments {
//Create the task
NSTask *task = [[NSTask alloc] init];

//Setup the task
[task setLaunchPath:base];
[task setArguments:arguments];
[task setStandardInput:[NSPipe pipe]];
[task setStandardOutput:[NSPipe pipe]];

//Set file handle
NSFileHandle *file = [[NSPipe pipe] fileHandleForReading];

//Run the command
[task launch];

//Return
NSData *returnData = [file readDataToEndOfFile];
return [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];}

和:

NSString *exposeEnable = [self runCommandWithBase:@"/usr/bin/defaults" 
                                            arguments:[NSArray arrayWithObjects:@"write", @"com.apple.dock", @"mcx-expose-disabled", @"-boolean", @"NO", nil]];
    NSLog(@"%@", exposeEnable);

NSString *exposeDisable = [self runCommandWithBase:@"/usr/bin/defaults" 
                                             arguments:[NSArray arrayWithObjects:@"write", @"com.apple.dock", @"mcx-expose-disabled", @"-boolean", @"YES", nil]];
    NSLog(@"%@", exposeDisable);

禁用属性

我尝试了一下，发现它是完全不稳定的，因为任务控制(暴露)不会总是重新启用-即使控制其enabled属性的文件说它已启用(〜/Library/Preferences/com.apple.dock.plist； mcx-expose-disabled的属性).是否有另一种更简单的方法，还是应该修改应用程序的设计，以使其不需要关闭这些内容?我可以继续使用当前方法并对其进行一些修改以便它可以正常工作(例如在默认情况下关闭其他属性)吗?

I tried this and found it to be completely unstable, as mission control (expose) would not always re-enable - even though the file that controls its enabled property says it is enabled (~/Library/Preferences/com.apple.dock.plist; the property of mcx-expose-disabled). Is there another, easier way, or should I modify my application's design so it does not require these things to be shut off? Can I continue using my current method with some modifications to it so it works (like shutting off different properties in defaults)?
