我正在使用Logos构建一个MobileSubstrate调整,我正在尝试添加一个新方法来将设备锁定到设备上的每个应用程序,这些应用程序将在接近更改通知后运行。到目前为止,我的代码是
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#import <SpringBoard/SpringBoard.h>
#import <SpringBoard/UIApplicationDelegate.h>
#import <GraphicsServices/GSEvent.h>
#include <notify.h>
@interface suspendresume : NSObject
@property(nonatomic, readonly) BOOL proximityState;
@end
@implementation suspendresume
BOOL tweakOn;
@end
static NSString *settingsFile = @"/var/mobile/Library/Preferences/com.matchstick.suspendresume.plist";
%hook SpringBoard
-(void)applicationDidFinishLaunching:(id)application {
// Allow SpringBoard to initialise
%orig;
// Set up proximity monitoring
[[UIDevice currentDevice] setProximityMonitoringEnabled:YES];
[[UIDevice currentDevice] proximityState];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(proximityChange:) name:@"UIDeviceProximityStateDidChangeNotification" object:nil];
}
%new
// Add new code into SpringBoard
-(void)proximityChange:(NSNotification*)notification {
[[UIDevice currentDevice] setProximityMonitoringEnabled:YES];
// Check if tweak is on
NSDictionary *dict = [[NSDictionary alloc] initWithContentsOfFile:settingsFile];
tweakOn = [[dict objectForKey:@"enabled"] boolValue];
// Only run if tweak is on
if (tweakOn) {
// Get first proximity value
if ([[UIDevice currentDevice] proximityState] == YES) {
// Wait a few seconds TODO allow changing of wait interval from prefrences FIXME causes a lockup of interface whilst sleeping
[self performSelector:@selector(lockDeviceAfterDelay) withObject:nil afterDelay:1.0];
}
}
}
%new
-(void)lockDeviceAfterDelay {
// Second proximity value
if ([[UIDevice currentDevice] proximityState] == YES) {
// Lock device
GSEventLockDevice();
}
}
%end
在SpringBoard中按照我的要求工作,但在设备上安装的任何其他应用程序中都没有 - 测试时发生的一切都是在触发接近传感器时显示器关闭,并且没有锁定设备。
我正在考虑使用UIApplicationDelegate
-(void)applicationDidFinishLaunching:(id)application
和UIApplication
在应用程序中实现与SpringBoard相同的功能,但无法弄清楚如何执行此操作。
这种方法的想法来自from this project
我是否需要将我在SpringBoard中运行的相同代码添加到UIApplication
下的新方法中?
我是否需要为每个应用程序重新设置邻近监控,以及在收到接近变更通知后如何调用这些新方法?
答案 0 :(得分:2)
原来这不是正确的方法。相反,
// Get the topmost application
SBApplication *runningApp = [(SpringBoard *)self _accessibilityFrontMostApplication];
// We're in application, resign app
[runningApp notifyResignActiveForReason:1];
做了这个伎俩。
