ios - 获取电池状态

Question

我在做游戏。

如果手机电池电量低于 60%，则产量递减量为 60 - current battery%

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

iOS 开发者库

UIDevice 类参考

您可以从这里下载示例。

Answer 2

如果您想获得电池充电，请使用此[UIDevice currentDevice].batteryLevel

它将返回一个浮点数 0.0 - 1.0。

Answer 3

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);
