iOS获取设备剩余存储空间代码片段

来源：互联网发布：qq群淘宝互刷是真的吗编辑：程序博客网时间：2024/06/11 18:29

首先需要引入相关的头文件，引入头文件代码如下：

#include <sys/param.h>#include <sys/mount.h>

获取剩余存储空间函数如下：

+ (NSString *) freeDiskSpaceInBytes{    struct statfs buf;    long long freespace = -1;    if(statfs("/var", &buf) >= 0){        freespace = (long long)(buf.f_bsize * buf.f_bfree);    }    return [NSString stringWithFormat:@"手机剩余存储空间为：%qi MB" ,freespace/1024/1024];}

iOS获取当前设备具体类型代码片段：

- (NSString *) platformString{    // Gets a string with the device model    size_t size;    sysctlbyname("hw.machine", NULL, &size, NULL, 0);    char *machine = malloc(size);    sysctlbyname("hw.machine", machine, &size, NULL, 0);    NSString *platform = [NSString stringWithCString:machine encoding:NSUTF8StringEncoding];    free(machine);    if ([platform isEqualToString:@"iPhone1,1"])    return @"iPhone 2G";    if ([platform isEqualToString:@"iPhone1,2"])    return @"iPhone 3G";    if ([platform isEqualToString:@"iPhone2,1"])    return @"iPhone 3GS";    if ([platform isEqualToString:@"iPhone3,1"])    return @"iPhone 4";    if ([platform isEqualToString:@"iPhone3,2"])    return @"iPhone 4";    if ([platform isEqualToString:@"iPhone3,3"])    return @"iPhone 4 (CDMA)";    if ([platform isEqualToString:@"iPhone4,1"])    return @"iPhone 4S";    if ([platform isEqualToString:@"iPhone5,1"])    return @"iPhone 5";    if ([platform isEqualToString:@"iPhone5,2"])    return @"iPhone 5 (GSM+CDMA)";        if ([platform isEqualToString:@"iPod1,1"])      return @"iPod Touch (1 Gen)";    if ([platform isEqualToString:@"iPod2,1"])      return @"iPod Touch (2 Gen)";    if ([platform isEqualToString:@"iPod3,1"])      return @"iPod Touch (3 Gen)";    if ([platform isEqualToString:@"iPod4,1"])      return @"iPod Touch (4 Gen)";    if ([platform isEqualToString:@"iPod5,1"])      return @"iPod Touch (5 Gen)";        if ([platform isEqualToString:@"iPad1,1"])      return @"iPad";    if ([platform isEqualToString:@"iPad1,2"])      return @"iPad 3G";    if ([platform isEqualToString:@"iPad2,1"])      return @"iPad 2 (WiFi)";    if ([platform isEqualToString:@"iPad2,2"])      return @"iPad 2";    if ([platform isEqualToString:@"iPad2,3"])      return @"iPad 2 (CDMA)";    if ([platform isEqualToString:@"iPad2,4"])      return @"iPad 2";    if ([platform isEqualToString:@"iPad2,5"])      return @"iPad Mini (WiFi)";    if ([platform isEqualToString:@"iPad2,6"])      return @"iPad Mini";    if ([platform isEqualToString:@"iPad2,7"])      return @"iPad Mini (GSM+CDMA)";    if ([platform isEqualToString:@"iPad3,1"])      return @"iPad 3 (WiFi)";    if ([platform isEqualToString:@"iPad3,2"])      return @"iPad 3 (GSM+CDMA)";    if ([platform isEqualToString:@"iPad3,3"])      return @"iPad 3";    if ([platform isEqualToString:@"iPad3,4"])      return @"iPad 4 (WiFi)";    if ([platform isEqualToString:@"iPad3,5"])      return @"iPad 4";    if ([platform isEqualToString:@"iPad3,6"])      return @"iPad 4 (GSM+CDMA)";        if ([platform isEqualToString:@"i386"])         return @"Simulator";    if ([platform isEqualToString:@"x86_64"])       return @"Simulator";    return platform;}
