获取手机各种信息
引言:
应用中经常会用到获取手机各种信息。
# 一. 获取手机电量
// 获取状态栏
UIStatusBar *statusBar = [[UIApplication sharedApplication] valueForKey:@"_statusBar"];
// 获取状态栏的前视图（视图中包括运营商，电池电量，信号，时间等等）
UIView *foregroundView = [[[[UIApplication sharedApplication] valueForKey:@"_statusBar"] subviews] lastObject];
// 获取到状态栏前视图的所有控件
NSArray *statusBarSubviews = [[[[[UIApplication sharedApplication] valueForKey:@"_statusBar"] subviews] lastObject] subviews];
for (id subview in statusBarSubviews) {
// 通过类名来获得电量
if ([subview isKindOfClass:NSClassFromString(@"UIStatusBarBatteryPercentItemView")])
{
//系统方法直接通过键值对拿到100%
result = [subview valueForKey:@"_percentString"];
}
}
// 得到的电量
return result;
# 二. 获取手机信息
# 1. 电池状态
NSInteger i = [UIDevice currentDevice].systemName;
/**
* UIDeviceBatteryStateUnknown：无法取得充电状态情况
UIDeviceBatteryStateUnplugged：非充电状态
UIDeviceBatteryStateCharging：充电状态
UIDeviceBatteryStateFull：充满状态（连接充电器充满状态）
*/
# 2. 设备所有者名称
UIDevice *device = [UIDevice currentDevice];
NSString *name = device.name;
# 3. 设备类型
// iphone ipad iwatch
NSString *name = [UIDevice currentDevice].model;
# 4. 系统类型
// iOS
NSString *name = [UIDevice currentDevice].systemName;
# 5. 系统版本号
// 10.1
NSString *name = [UIDevice currentDevice].systemVersion;
# 6. 获取设备唯一标识符
// 6C0AA68D-303F-4422-9E4C-5FED956F9408
UIDevice *device = [UIDevice currentDevice];
NSLog(@"%@", [device.identifierForVendor UUIDString]);
# 7. 运行商的名称
导入两个头文件：
#import <CoreTelephony/CTCarrier.h>
#import <CoreTelephony/CTTelephonyNetworkInfo.h>
CTTelephonyNetworkInfo *info = [[CTTelephonyNetworkInfo alloc] init];
NSString *operators = [info subscriberCellularProvider].carrierName;
NSLog(@"%@", operators);
# 8. 网络状态
NSArray *children = [[[[UIApplication sharedApplication] valueForKeyPath:@"statusBar"] valueForKeyPath:@"foregroundView"] subviews];
NSString *state = [[NSString alloc] init];
int netType = 0;
//获取到网络返回码
for (id child in children) {
if ([child isKindOfClass:NSClassFromString(@"UIStatusBarDataNetworkItemView")]) {
//获取到状态栏
netType = [[child valueForKeyPath:@"dataNetworkType"]intValue];
switch (netType) {
case 0:
state = @"无网络";//无网模式
break;
case 1:
state = @"2G";
break;
case 2:
state = @"3G";
break;
case 3:
state = @"4G";
break;
case 5:
state = @"WIFI";
break;
default:
break;
}
}
}
# 三. 获取内存
需要导入#import <mach/mach.h>包。
# 1. 手机内存
// 获得手机内存
unsigned long long fileSize = [NSProcessInfo processInfo].physicalMemory;
// 容量转换
NSInteger KB = 1024;
NSInteger MB = KB*KB;
NSInteger GB = MB*
NSString *fileSizeStr = @"";
if (fileSize < 10) {
fileSizeStr = @"0 B";
}else if (fileSize < KB) {
fileSizeStr = @"< 1 KB";
}else if (fileSize < MB) {
fileSizeStr = [NSString stringWithFormat:@"%.1f KB",((CGFloat)fileSize)/KB];
}else if (fileSize < GB) {
fileSizeStr = [NSString stringWithFormat:@"%.1f MB",((CGFloat)fileSize)/MB];
}else {
fileSizeStr = [NSString stringWithFormat:@"%.1f GB",((CGFloat)fileSize)/GB];
}
NSLog(@"%@", fileSizeStr);
# 2. 获取可用内存
// 获取可用内存
unsigned long long usableFileSize = 0;
vm_statistics_data_t vmStats;
mach_msg_type_number_t infoCount = HOST_VM_INFO_COUNT;
kern_return_t kernReturn = host_statistics(mach_host_self(), HOST_VM_INFO, (host_info_t)&vmStats, &infoCount);
if (kernReturn != KERN_SUCCESS){
usableFileSize = NSNotFound;
}
usableFileSize = ((vm_page_size * vmStats.free_count + vm_page_size * vmStats.inactive_count));
// 容量转换
NSInteger KB = 1024;
NSInteger MB = KB*KB;
NSInteger GB = MB*KB;
NSString *usableFileSizeStr = @"";
if (usableFileSize < 10) {
usableFileSizeStr = @"0 B";
}else if (usableFileSize < KB) {
usableFileSizeStr = @"< 1 KB";
}else if (usableFileSize < MB) {
usableFileSizeStr = [NSString stringWithFormat:@"%.1f KB",((CGFloat)usableFileSize)/KB];
}else if (usableFileSize < GB) {
usableFileSizeStr = [NSString stringWithFormat:@"%.1f MB",((CGFloat)usableFileSize)/MB];
}else {
usableFileSizeStr = [NSString stringWithFormat:@"%.1f GB",((CGFloat)usableFileSize)/GB];
}
NSLog(@"%@", usableFileSizeStr);
# 四. 获取设备类型
需要导入：#import <sys/sysctl.h>包
// 调用
NSString *deviceType = [self getCurrentDeviceModel:self]；
//5.获取设备型号
-(NSString *)getCurrentDeviceModel:(UIViewController *)controller
{
int mib[2];
