清理缓存

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 :%ld",[files count]);
for (NSString *p in files)
{
NSError *error;
NSString *path = [cachPath stringByAppendingPathComponent:p];
if ([[NSFileManager defaultManager] fileExistsAtPath:path])
{
[[NSFileManager defaultManager] removeItemAtPath:path error:&error];
}
}
[self performSelectorOnMainThread:@selector(clearCacheSuccess) withObject:nil waitUntilDone:YES];
}
);

清理成功后的回调

-(void)clearCacheSuccess
{
NSLog(@"清理成功");
}
