如何使用 Swift 检测锁定/解锁的 iOS 设备(如 Android 中的 SCRENON/SCREENOFF)

Answer 1

我使用以下方法创建相同的想法。

您需要使用 bridge 将 objective c 代码用于 swift。

Here is the Link for create the bridge between the Objective c to Swift.

完成后，您可以将以下 .h 文件添加到 yourproject-Bridging-Header 中。文件添加 yourcontroller.h

然后将 NotificationCenter.framework 添加到您的项目中。

进入你的 CustomObject.m

#import "notify.h"

-(void)registerAppforDetectLockState {

    int notify_token;
    notify_register_dispatch("com.apple.springboard.lockstate", &notify_token,dispatch_get_main_queue(), ^(int token) {

        uint64_t state = UINT64_MAX;
        notify_get_state(token, &state);

        if(state == 0) {
            NSLog(@"unlock device");
        } else {
            NSLog(@"lock device");
        }

        NSLog(@"com.apple.springboard.lockstate = %llu", state);
        UILocalNotification *notification = [[UILocalNotification alloc]init];
        notification.repeatInterval = NSCalendarUnitDay;
        [notification setAlertBody:@"Hello world!! I come becoz you lock/unlock your device :)"];
        notification.alertAction = @"View";
        notification.alertAction = @"Yes";
        [notification setFireDate:[NSDate dateWithTimeIntervalSinceNow:1]];
        notification.soundName = UILocalNotificationDefaultSoundName;
        [notification setTimeZone:[NSTimeZone  defaultTimeZone]];

        [[UIApplication sharedApplication] presentLocalNotificationNow:notification];

    });
}

然后是 CustomObject.h

-(void)registerAppforDetectLockState;

现在进入swift代码你可以直接使用这个方法。

var instanceOfCustomObject: LockViewController = LockViewController()
instanceOfCustomObject.registerAppforDetectLockState();

希望这对您有帮助。
