一段清理緩存的代碼如下:

dispatch_async(

dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT,0)

, ^{

NSString *cachPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory,NSUserDomainMask,
YES)objectAtIndex:0];

NSArray *files = [[NSFileManager
defaultManager] subpathsAtPath:cachPath];

NSLog(@”files :%d”,[files
count]);

for (NSString *p
in files) {

NSError *error;

NSString *path = [cachPath
stringByAppendingPathComponent:p];

if ([[NSFileManagerdefaultManager]
fileExistsAtPath:path]) {

[[NSFileManagerdefaultManager]
removeItemAtPath:patherror:&error];

}

}

[selfperformSelectorOnMainThread:@selector(clearCacheSuccess)withObject:nilwaitUntilDone:YES];});

-(void)clearCacheSuccess

{

NSLog(@”清理成功”);

}
