不多说，直接上代码，如下：
- (void)clearCaChe
{
NSString *cachPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSArray *files = [[NSFileManager defaultManager] subpathsAtPath:cachPath];
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];
}
- (void)clearCacheSuccess
{
//清理成功后要做的操作
}
