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;
}
/*
如何获取设备的总容量和可用容量
*/
+ (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
