我正在尝试从我的偏好中删除特定的服务名称,但遗憾的是,在尝试使用以下功能时,我收到1003错误:SCPreferencesLock,SCPreferencesCommitChanges,SCPreferencesApplyChanges。
它特定于kSCStatusAccessError的1003代码,这意味着即使AuthorizationRef是root,我也没有root权限。
// Create AuthorizationRef
AuthorizationRef auth = NULL;
OSStatus status;
AuthorizationFlags rootFlags = kAuthorizationFlagDefaults |
kAuthorizationFlagInteractionAllowed |
kAuthorizationFlagPreAuthorize |
kAuthorizationFlagExtendRights;
// Get default authorization
status = AuthorizationCreate(NULL, kAuthorizationEmptyEnvironment, rootFlags, &auth);
SCPreferencesRef preferences;
if (status == noErr) {
preferences = SCPreferencesCreateWithAuthorization(NULL, CFSTR("personal.configuration"), NULL, auth);
NSLog(@"Root autehntication");
} else {
preferences = SCPreferencesCreate(NULL, CFSTR("personal.configuration"), NULL);
NSLog(@"Default autehntication");
}
if(preferences == NULL) {
NSLog(@"Could not create preferences");
}
CFArrayRef servicesArray = SCNetworkServiceCopyAll(preferences);
if (servicesArray == NULL) {
NSLog(@"No network services");
}
// Get list of available services
SCNetworkServiceRef service;
for (int i = 0; i < CFArrayGetCount(servicesArray); i++) {
// Get service reference
service = (SCNetworkServiceRef)CFArrayGetValueAtIndex(servicesArray, i);
// Get service anme
CFStringRef serviceName = SCNetworkServiceGetName(service);
NSString* strServiceName= (__bridge NSString *)(serviceName);
NSLog(@"New network serivice found: %@", strServiceName);
if ([strServiceName isEqualToString:@"Specific name"]) {
if (!SCPreferencesLock(preferences, TRUE)){
NSLog(@"\tFailed to call SCPreferencesLock: %d", SCError());
}
if(SCNetworkServiceRemove(service)) {
NSLog(@"\tInternet Service successfully removed!");
}
if (!SCPreferencesCommitChanges(preferences)) {
NSLog(@"\tFailed to commit preferences changes: %d", SCError());
}
if (!SCPreferencesApplyChanges(preferences)) {
NSLog(@"\tFailed to apply preferences changes: %d", SCError());
}
SCPreferencesSynchronize(preferences);
if (!SCPreferencesUnlock(preferences)) {
NSLog(@"\tFailed to unlock preferences: %d", SCError());
}
}
}
CFRelease(servicesArray);

根据评论,问题是应用程序正在使用Cocoa沙箱。
使用App Sandbox,您的应用无法修改系统的网络配置(无论是使用系统配置框架,CoreWLAN框架还是其他类似的API),因为这样做需要管理员权限。
如果要修改系统配置框架,则无法使用沙箱。
您可以转到应用程序权利文件并将条目App Sandbox
更改为NO
来禁用沙箱,然后会出现安全对话框。
