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 #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];
