1.找到SDImageCache类

2.添加如下方法：

[objc] view plain copy- (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; }

新版的SDImageCache类，已增加此方法

[objc] view plain copy[[SDImageCache sharedImageCache] getSize];

3.在设置里这样使用

[objc] view plain copy#PRagma 清理缓存图片 - (void)clearTmpPics { [[SDImageCache sharedImageCache] clearDisk]; // [[SDImageCache sharedImageCache] clearMemory];//可有可无 DLog(@"clear disk"); float tmpSize = [[SDImageCache sharedImageCache] checkTmpSize]; NSString *clearCacheName = tmpSize >= 1 ? [NSString stringWithFormat:@"清理缓存(%.2fM)",tmpSize] : [NSString stringWithFormat:@"清理缓存(%.2fK)",tmpSize * 1024]; [configDataArray replaceObjectAtIndex:2 withObject:clearCacheName]; [configTableView reloadData]; }
