SDWebImage找到SDImageCache类 然后调用
- (float)checkTmpSize
{
float totalSize = 0;
NSDirectoryEnumerator *fileEnumerator = [[NSFileManager defaultManager] enumeratorAtPath:_diskCachePath];
for (NSString *fileName in fileEnumerator)
{
NSString *filePath = [_diskCachePath stringByAppendingPathComponent:fileName];
NSDictionary *attrs = [[NSFileManager defaultManager] attributesOfItemAtPath:filePath error:nil];
unsigned long long length = [attrs fileSize];
totalSize += length / 1024.0 / 1024.0;
}
// NSLog(@"tmp size is %.2f",totalSize);
return totalSize;
}
然后调用
