iOS开发 - 如何获取设备的总容量和可用容量 网络运营商 3g/wifi判断 手机型号
镔哥最近开发需获取手机容量，其实这你是一个很好的例子
//硬盘容量
- (float)getTotalDiskSpace
{
float totalSpace;
NSError * error;
NSDictionary * infoDic = [[NSFileManager defaultManager] attributesOfFileSystemForPath:[self getHomeDirectory] error: &error];
if (infoDic) {
NSNumber * fileSystemSizeInBytes = [infoDic objectForKey: NSFileSystemSize];
totalSpace = [fileSystemSizeInBytes floatValue]/1024.0f/1024.0f/1024.0f;
return totalSpace;
} else {
NSLog(@"Error Obtaining System Memory Info: Domain = %@, Code = %ld", [error domain], (long)[error code]);
return 0;
}
}
- (NSString *)getHomeDirectory
{
NSString * homePath = NSHomeDirectory();
return homePath;
}
/*

*/
+ (NSNumber *)totalDiskSpace
{
NSDictionary *fattributes = [[NSFileManager defaultManager] attributesOfFileSystemForPath:NSHomeDirectory() error:nil];
return [fattributes objectForKey:NSFileSystemSize];
}
+ (NSNumber *)freeDiskSpace
{
NSDictionary *fattributes = [[NSFileManager defaultManager] attributesOfFileSystemForPath:NSHomeDirectory() error:nil];
return [fattributes objectForKey:NSFileSystemFreeSize];
}
//手机型号（这跟系统获取的不一样，这是获取iPhone5，4，6之类的）要导入
#import "sys/utsname.h"
+ (NSString*)deviceString
{
// 需要#import "sys/utsname.h"
struct utsname systemInfo;
uname(&systemInfo);
NSString *deviceString = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
if ([deviceString isEqualToString:@"iPhone1,1"]) return @"iPhone 1G";

if ([deviceString isEqualToString:@"i386"]) return @"Simulator";
if ([deviceString isEqualToString:@"x86_64"]) return @"Simulator";
NSLog(@"NOTE: Unknown device type: %@", deviceString);
return deviceString;
}
// 判读是3g还是Wi-Fi 要导入#import"Reachability.h"
Reachability *reachbility=[Reachability reachabilityWithHostName:@"www.baidu.com"]; NetworkStatus status=[reachbility currentReachabilityStatus];
NSString *netStr;
//使用 WiFi 网络连接
if (status==ReachableViaWiFi)
{
netStr = @"wifi";
//[[NSUserDefaults standardUserDefaults]setObject:netStr forKey:@"network"];
}
else if(status ==ReachableViaWWAN)
{
netStr = @"3g";
//[[NSUserDefaults standardUserDefaults]setObject:netStr forKey:@"network"];
}
NSLog(@"网络是：%@",netStr);
/*关于获取运营商信息，需通过CoreTelephony Framework中的CTTelephonyNetworkInfo和CTCarrier类型。这些都在iOS 4.0后就有了。
