显示ios设备信息的程序

学习ios开发一小段时间啦，分享个个人练习的小作品，有越狱过的童鞋可以装上看看，由于用了2、3个undocument api，所以那个。。。。
高手可以无视啦。

以下是运行在本人iphone4上的截图，支持中文简体，中文繁体，英文，支持iphone和ipad，当然由于没有ipad，ipad的测试用的模拟器。
支持iphone4的Retina屏幕。
本来有6个标签，但是iphone的很多信息实在得不到，现在只剩下了4个标签。

这里面的电量精确到0.01，用的undocument api，但是个人感觉总是比右上角系统自己显示的偏低3%以内。

显示当前运行的进程，但是不知道如何得到进程的图标，因此统一用的图标。

一些硬件信息，iphone4的A4 cpu频率实际上得不到，始终显示为0，只好根据手机型号判断，如果是iphone4则显示800Mhz，（据说是1G的cpu降频到800Mhz）。

宣传devdiv的信息。

ipa包如下：
FeiPhoneInfo.ipa

图标来源于网络。

每张图中右边的圆圈是ios5的手势触摸的东东。
展开来后是这个样子，可以有效的降低home键的使用。

部分信息是UIDevice里的。
电池信息可以从UIDevice batteryLevel得到，但是只能精确到0.05.

– (NSDictionary*)batteryLevel
{
CFTypeRef blob = IOPSCopyPowerSourcesInfo();
CFArrayRef sources = IOPSCopyPowerSourcesList(blob);
CFDictionaryRef pSource = NULL;
const void *psValue;
int numOfSources = CFArrayGetCount(sources);
if (numOfSources == 0)
{
CFRelease(blob);
CFRelease(sources);
NSLog(@“qhk: Error in CFArrayGetCount”);
return nil;
}
for (int i = 0 ; i < numOfSources ; i++)
{
pSource = IOPSGetPowerSourceDescription(blob, CFArrayGetValueAtIndex(sources, i));
if (!pSource)
{
CFRelease(blob);
CFRelease(sources);
NSLog(@“qhk: Error in IOPSGetPowerSourceDescription”);
return nil;
}
psValue = (CFStringRef)CFDictionaryGetValue(pSource, CFSTR(kIOPSNameKey));
int curCapacity = 0;
int maxCapacity = 0;
// double percent;
psValue = CFDictionaryGetValue(pSource, CFSTR(kIOPSCurrentCapacityKey));
CFNumberGetValue((CFNumberRef)psValue, kCFNumberSInt32Type, >curCapacity);
psValue = CFDictionaryGetValue(pSource, CFSTR(kIOPSMaxCapacityKey));
CFNumberGetValue((CFNumberRef)psValue, kCFNumberSInt32Type, >maxCapacity);
// percent = ((double)curCapacity/(double)maxCapacity * 100.0f);
NSNumber* no1 = [NSNumber numberWithInt:curCapacity];
NSNumber* no2= [NSNumber numberWithInt:maxCapacity];
CFRelease(blob);
CFRelease(sources);
return [NSDictionary dictionaryWithObjectsAndKeys:no1, @\”no1\”, no2, @\”no2\”, nil];
// return percent;
// return (NSInteger)(percent + 0.5f);
}
//#endif
CFRelease(blob);
CFRelease(sources);
return nil;
}

这个可以精确到0.01，但是好像与系统显示的仍有偏差。得到平台号：

– (NSString*) doDevicePlatform
{
size_t size;
int nR = sysctlbyname(“hw.machine”, NULL, >size, NULL, 0);
char *machine = (char *)malloc(size);
nR = sysctlbyname(“hw.machine”, machine, >size, NULL, 0);
NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];
free(machine);
return platform;
}

在根据平台号得到手机型号：
比如：

if ([platform isEqualToString:@\”iPhone1,1\”])
{
return @“iPhone”;
}
if ([platform isEqualToString:@\”iPhone1,2\”])
{
return @“iPhone3G”;
}
if ([platform isEqualToString:@\”iPhone2,1\”])
{
return @“iPhone3GS”;
}
if ([platform isEqualToString:@\”iPhone3,1\”])
{
return @“iPhone4″;
}

得到mac地址：

– (void)printmacinfo
{
bool success;
struct ifaddrs *addrs;
const struct ifaddrs *cursor;
const struct sockaddr_dl *dlAddr;
const uint8_t *base;
success = getifaddrs(>addrs) == 0;
if (success)
{
cursor = addrs;
NSInteger idx = 0;
while (cursor != NULL)
{
++idx;
NSString* macTitle = nil;
if ((cursor->ifa_flags > IFF_LOOPBACK) == 0 )
{
char* ifaname = (char *)cursor->ifa_name;
char* addr = inet_ntoa(((struct sockaddr_in *)cursor->ifa_addr)->sin_addr);
printf(“%s ”, ifaname);
printf(“%s\\n”, addr);
// NSString* tmpstr1 = [NSString stringWithCString:ifaname encoding:NSUTF8StringEncoding];
// NSString* tmpstr2 = [NSString stringWithCString:addr encoding:NSUTF8StringEncoding];
// NSString *tmpStr = [NSString stringWithFormat:@\”%@ %@\”, tmpstr1, tmpstr2];
macTitle = [NSString stringWithFormat:@\”%d %s %s\”, idx, ifaname, addr];
[_arrKey addObject:macTitle];
}
if ( (cursor->ifa_addr->sa_family == AF_LINK)
>> (((const struct sockaddr_dl *) cursor->ifa_addr)->sdl_type ==IFT_ETHER)
)
{
dlAddr = (const struct sockaddr_dl *) cursor->ifa_addr;
// fprintf(stderr, ” sdl_nlen = %d\\n”, dlAddr->sdl_nlen);
// fprintf(stderr, ” sdl_alen = %d\\n”, dlAddr->sdl_alen);
base = (const uint8_t *) >dlAddr->sdl_data[dlAddr->sdl_nlen];
printf(“ MAC address ”);
NSMutableString* tmpString = [[[NSMutableString alloc] initWithString:@“Mac:”] autorelease];
for (int i = 0; i < dlAddr->sdl_alen; i++)
{
if (i != 0)
{
printf(“:”);
[tmpString appendString:@\”:\”];
}
printf(“%02x”, base[i]);
[tmpString appendFormat:@\”%02X\”, base[i]];
}
printf(“\\n”);
[_dic setObject:tmpString forKey:macTitle];
}
else if (macTitle != nil)
{
[_dic setObject:@\”\” forKey:macTitle];
}
cursor = cursor->ifa_next;
}
}
}

页大小

int pageSize = 0;
size_t length = sizeof(pageSize);
sysctlbyname(“hw.pagesize”, >pageSize, >length, NULL, 0);

得到4种内存信息：

mach_msg_type_number_t count = HOST_VM_INFO_COUNT;
vm_statistics_data_t vmstat;
if (host_statistics(mach_host_self(), HOST_VM_INFO, (host_info_t)>vmstat, >count) != KERN_SUCCESS)
{
NSLog(@“Failed to get VM statistics.”);
[_dic setObject:@\”Failed to get VM statistics.\” forKey:KTTMemorySize_Wire];
}
else
{
float total = vmstat.wire_count + vmstat.active_count + vmstat.inactive_count + vmstat.free_count;
float wired = vmstat.wire_count / total * 100;
float active = vmstat.active_count / total * 100;
float inactive = vmstat.inactive_count / total * 100;
float free = vmstat.free_count / total * 100;
// NSString *str = [NSString stringWithFormat:@\”%d %d %d %d %.2f %.2f %.2f %.2f %.0f %.0f\”
// , vmstat.wire_count, vmstat.active_count, vmstat.inactive_count, vmstat.free_count
// , wired, active, inactive, free
// , total, total * pageSize
// ];
}

cpu和总线频率：

int result;
mib[0] = CTL_HW;
mib[1] = HW_CPU_FREQ;
length = sizeof(result);
if (sysctl(mib, 2, >result, >length, NULL, 0) < 0)
{
perror(“getting cpu frequency”);
}
printf(“CPU Frequency = %u hz\\n”, result);
int result2;
mib[0] = CTL_HW;
mib[1] = HW_BUS_FREQ;
length = sizeof(result2);
if (sysctl(mib, 2, >result2, >length, NULL, 0) < 0)
{
perror(“getting bus frequency”);
}
printf(“Bus Frequency = %u hz\\n”, result);

网络方面使用的苹果列子文档中的Reachability.h和Reachability.m
外部ip访问http://automation.whatismyip.com/n09230945.asp即可知道。
gethostbyname可知内部局域网ip。

NetworkStatus netstatus = [reachable currentReachabilityStatus];
switch (netstatus)
{
case NotReachable:
// 没有网络连接
reachableStatus = NSLocalizedString(@“No Network”, “”);
break;
case ReachableViaWWAN:
// 使用3G网络
reachableStatus = @“GPRS/3G”;
break;
case ReachableViaWiFi:
// 使用WiFi网络
reachableStatus = @“WIFI”;
break;
}

这个可知网络类型。内存大小：

size_t size = sizeof(int);
int results;
int mib[2] = {CTL_HW, HW_PHYSMEM};
sysctl(mib, 2, >results, >size, NULL, 0);

总磁盘大小：

NSDictionary *fattributes = [[NSFileManager defaultManager] attributesOfFileSystemForPath:NSHomeDirectory() error:nil];
[fattributes objectForKey:NSFileSystemSize];

剩余空间：

[fattributes objectForKey:NSFileSystemFreeSize];

手机号码：
这个也是undocument api

NSString* phoneNumber = CTSettingCopyMyPhoneNumber();

NSArray *getValue(NSString *iosearch)
{
mach_port_t masterPort;
CFTypeID propID = (CFTypeID) NULL;
unsigned int bufSize;
kern_return_t kr = IOMasterPort(MACH_PORT_NULL, >masterPort);
if (kr != noErr) return nil;
io_registry_entry_t entry = IORegistryGetRootEntry(masterPort);
if (entry == MACH_PORT_NULL) return nil;
CFTypeRef prop = IORegistryEntrySearchCFProperty(entry, kIODeviceTreePlane, (CFStringRef) iosearch, nil, kIORegistryIterateRecursively);
if (!prop) return nil;
propID = CFGetTypeID(prop);
if (!(propID == CFDataGetTypeID()))
{
mach_port_deallocate(mach_task_self(), masterPort);
CFRelease(prop);
return nil;
}
CFDataRef propData = (CFDataRef) prop;
if (!propData)
{
CFRelease(prop);
return nil;
}
bufSize = CFDataGetLength(propData);
if (!bufSize)
{
CFRelease(prop);
return nil;
}
NSString *p1 = [[[NSString alloc] initWithBytes:CFDataGetBytePtr(propData) length:bufSize encoding:1] autorelease];
mach_port_deallocate(mach_task_self(), masterPort);
CFRelease(prop);
return [p1 componentsSeparatedByString:@\”\\0\”];
}
