获取iOS设备信息(内存/电量/容量/型号/IP地址/当前WIFI名称)
1.获取电池电量(一般用百分数表示,大家自行处理就好)

-(CGFloat)getBatteryQuantity { return [[UIDevice currentDevice] batteryLevel]; } |
2.获取电池状态(UIDeviceBatteryState为枚举类型)

-(UIDeviceBatteryState)getBatteryStauts { return [UIDevice currentDevice].batteryState; } |
3.获取总内存大小

-(long long)getTotalMemorySize { return [NSProcessInfo processInfo].physicalMemory; } |
4.获取当前可用内存

可以根据自己的需求增改。有人说也可以按照手机屏幕来判断,但5和5s/5c等手机屏幕相同尺寸则无法判断。。。我只做了iPhone的机型,所以iPad和iPod Touch的信息并没有更新到最新,也请朋友们补充。
