   #define PATH_OF_CACHES  [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject]

self.dataLb.text = [NSString stringWithFormat:@”%ld kB”,[PATH_OF_CACHES fileSize]];
NSString 的category中添加的方法
计算com.hackemist.SDWebImageCache.default和OnlineDownloadSkyFile下的文件夹大小

- (NSInteger) fileSize{NSFileManager *fileManager = [NSFileManager defaultManager];BOOL dir = NO;BOOL isExists = [fileManager fileExistsAtPath:self isDirectory:&dir];if (isExists == NO) return 0;if (dir) {    NSArray *subPaths = [fileManager subpathsAtPath:self];    NSInteger totalByteSize = 0;    for (NSString *subPath in subPaths) {        NSString *fullSubPath = [self stringByAppendingPathComponent:subPath];        BOOL isDirectory = NO;        [fileManager fileExistsAtPath:fullSubPath isDirectory:&isDirectory];        if (isDirectory == NO) {            if ([fullSubPath containsString:@"com.hackemist.SDWebImageCache.default"] ||[fullSubPath containsString:@"OnlineDownloadSkyFile"]) {                totalByteSize += [[fileManager attributesOfItemAtPath:fullSubPath error:nil][NSFileSize] integerValue];            }        }    }     return totalByteSize;}else{    return [[fileManager attributesOfItemAtPath:self error:nil][NSFileSize] integerValue];}}
