1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
//磁盘总空间 + (CGFloat)diskOfAllSizeMBytes{ CGFloat size = 0.0; NSError *error; NSDictionary *dic = [[NSFileManager defaultManager] attributesOfFileSystemForPath:NSHomeDirectory() error:&error]; if (error) { #ifdef DEBUG NSLog(@"error: %@", error.localizedDescription); #endif }else{ NSNumber *number = [dic objectForKey:NSFileSystemSize]; size = [number floatValue]/1024/1024; } return size; } |
2. 获取磁盘可用空间大小

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
//磁盘可用空间 + (CGFloat)diskOfFreeSizeMBytes{ CGFloat size = 0.0; NSError *error; NSDictionary *dic = [[NSFileManager defaultManager] attributesOfFileSystemForPath:NSHomeDirectory() error:&error]; if (error) { #ifdef DEBUG NSLog(@"error: %@", error.localizedDescription); #endif }else{ NSNumber *number = [dic objectForKey:NSFileSystemFreeSize]; size = [number floatValue]/1024/1024; } return size; } |
3. 获取指定路径下某个文件的大小

1 2 3 4 5 6 |
//获取文件大小 + (long long)fileSizeAtPath:(NSString *)filePath{ NSFileManager *fileManager = [NSFileManager defaultManager]; if (![fileManager fileExistsAtPath:filePath]) return 0; return [[fileManager attributesOfItemAtPath:filePath error:nil] fileSize]; } |
4. 获取文件夹下所有文件的大小
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
//获取文件夹下所有文件的大小 + (long long)folderSizeAtPath:(NSString *)folderPath{ NSFileManager *fileManager = [NSFileManager defaultManager]; if (![fileManager fileExistsAtPath:folderPath]) return 0; NSEnumerator *filesEnumerator = [[fileManager subpathsAtPath:folderPath] objectEnumerator]; NSString *fileName; long long folerSize = 0; while ((fileName = [filesEnumerator nextObject]) != nil) { NSString *filePath = [folderPath stringByAppendingPathComponent:fileName]; folerSize += [self fileSizeAtPath:filePath]; } return folerSion-v">:filePath]; } return folerSi ar" data-settings=" show" style="font-size: 13px !important;height: 19.5px !important; line-height: 19.5px !important;">
