ios - 获取电池状态

Question

我正在制作游戏。

如果手机的电池电量低于 60%，则产量递减为 60 - 当前电池电量%

所以，我的问题是: 我可以在 iOS 中获取有关电池百分比的信息吗？

Answer 1

NSArray *stateArray = @[@"Battery state is unknown", 
                        @"Battery is not plugged into a charging source", 
                        @"Battery is charging", 
                        @"Battery state is full"];

NSString *status = [NSString stringWithFormat:@"Battery state: %@, Battery level: %0.2f%%",
                    stateArray[[UIDevice currentDevice].batteryState],
                    [UIDevice currentDevice].batteryLevel * 100];

NSLog(@"%@", status);
