镔哥最近開發需獲取手機容量，其實這你是一個很好的例子

//硬盤容量

- (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;

}

/*

如何獲取設備的總容量和可用容量

*/

+ (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];

}

//手機型號（這跟系統獲取的不一樣，這是獲取iPhone5，4，6之類的）要導入

#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;

}

// 判讀是3g還是Wi-Fi 要導入#import"Reachability.h"

Reachability *reachbility=[Reachability reachabilityWithHostName:@"www.baidu.com"]; NetworkStatus status=[reachbility currentReachabilityStatus];

NSString *netStr;

//使用 WiFi 網絡連接

if (status==ReachableViaWiFi)

{

netStr = @"wifi";

//[[NSUserDefaults standardUserDefaults]setObject:netStr forKey:@"network"];

}

else if(status ==ReachableViaWWAN)

{

netStr = @"3g";

//[[NSUserDefaults standardUserDefaults]setObject:netStr forKey:@"network"];

}

NSLog(@"網絡是：%@",netStr);

/*關於獲取運營商信息，需通過CoreTelephony Framework中的CTTelephonyNetworkInfo和CTCarrier類型。這些都在iOS 4.0後就有了。

import必要的header：
