感觉就 获取系统版本用的最多。。
** [[UIDevice currentDevice] systemVersion] **
基本信息
- (void)deviceInfo {
UIDevice *currentDevice = [UIDevice currentDevice];// 当前设备
NSLog(@"%@",currentDevice.name);
NSLog(@"%@",currentDevice.model);
NSLog(@"%@",currentDevice.localizedModel);
NSLog(@"%@",currentDevice.systemName);
NSLog(@"%@",currentDevice.systemVersion);// 一般拿这个 判断 iOS 9.2 还是啥啥啥的。基本都搞成宏定义了是吧。
NSLog(@"%@",currentDevice.identifierForVendor);
NSLog(@"%zi",currentDevice.multitaskingSupported);
NSLog(@"%zi",currentDevice.userInterfaceIdiom);
/*！ 设备交互界面类型

UIUserInterfaceIdiomTV NS_ENUM_AVAILABLE_IOS(9_0), // Apple TV style UI
};
*/
}
设备方向
- (void)orientationControl {
// 通知 开关，默认开
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[UIDevice currentDevice] endGeneratingDeviceOrientationNotifications];
// 判断是否开启通知
if ([UIDevice currentDevice].generatesDeviceOrientationNotifications) {
// 添加通知
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(OrientationDidChange:) name:UIDeviceOrientationDidChangeNotification object:nil];
}
}
// 通知 回调 发现改变
- (void)OrientationDidChange:(NSNotification *)notification {
NSLog(@"%@",notification.userInfo);// 貌似没什么软用
NSLog(@"%zi",[UIDevice currentDevice].orientation);// 还是查看这个比较靠谱。
/*! 上 下 左 右 正 反
typedef NS_ENUM(NSInteger, UIDeviceOrientation) {

UIDeviceOrientationFaceDown // Device oriented flat, face down
} __TVOS_PROHIBITED;
*/
// 系统默认 inline 函数，判断是否竖屏，横屏，其实就是 上面的 （上或者下）和 （左或者右）。
if (UIDeviceOrientationIsPortrait([UIDevice currentDevice].orientation)) {
NSLog(@"Portrait");
}
if (UIDeviceOrientationIsLandscape([UIDevice currentDevice].orientation)) {

电池信息
- (void)batteryInfo {
NSLog(@"电池状态 %zi",[UIDevice currentDevice].batteryState);
NSLog(@"电池电量等级百分比0-1 : %f",[UIDevice currentDevice].batteryLevel);
// 是否开启 电池信息检查

/*！ 几个状态，恩~~
typedef NS_ENUM(NSInteger, UIDeviceBatteryState) {
UIDeviceBatteryStateUnknown,
UIDeviceBatteryStateUnplugged, // on battery, discharging
UIDeviceBatteryStateCharging, // plugged in, less than 100%
UIDeviceBatteryStateFull, // plugged in, at 100%
};
*/
}
- (void)batteryLevelDidChange {
NSLog(@"电池电量等级%f",[UIDevice currentDevice].batteryLevel);
}
顶部的距离感应
- (void)proximityControl {
// 是否 接近 顶部的 距离传感器（正中央上面的原点！贴膜的朋友，可以看到膜是缺口的哦~），遮住屏幕会变黑，打电话时贴脸就黑一样，对应有通知。
[UIDevice currentDevice].proximityMonitoringEnabled = YES;

}
- (void)proximityStateDidChange {
if ([UIDevice currentDevice].proximityState) {
NSLog(@"要遮住了");
} else {
NSLog(@"走开了");
}
