一段清理緩存的代碼例如以下：

dispatch_async(

dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT,0)

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

NSArray *files = [[NSFileManager

NSLog(@"files :%d",[files count]);

for (NSString *p in files) {

NSError *error;

NSString *path = [cachPath stringByAppendingPathComponent:p];

if

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

}

}

[selfperformSelectorOnMainThread:@selector(clearCacheSuccess)withObject

-(void)clearCacheSuccess

{

NSLog(@"清理成功");

}
