如何删掉某个应用在keychain中创建的内容？
没有越狱的情况下，能实现么？
越狱的情况下，能实现么？

越狱的话是可以实现的，直接把keychain删掉就好了；不越狱的话我不确定

直接把keychain删掉?请问怎么样才能把keychain删掉呢？
我hook了下面的方法
%hook SFHFKeychainUtils

  • (NSString *) getPasswordForUsername: (NSString *) username andServiceName: (NSString *) serviceName error: (NSError **) error
    {
    NSLog(@“getPasswordForUsername:%@,%@”,username,serviceName);
    return %orig;
    }
    %end

这样得到username,serviceName之后，我想就可以再想办法删掉了，
大神，你怎么做的呢？

下面是我从某个清痕App上扒下来的代码：

	sqlite3 *database;
	int openResult = sqlite3_open("/var/Keychains/keychain-2.db", &database);
	if (openResult == SQLITE_OK)
	{
		int execResult = sqlite3_exec(database, "DELETE FROM genp WHERE agrp <> 'apple'", NULL, NULL, NULL);
		if (execResult != SQLITE_OK) NSLog(@"Failed to exec DELETE FROM genp WHERE agrp <> 'apple', error %d", execResult);

		execResult = sqlite3_exec(database, "DELETE FROM cert WHERE agrp <> 'lockdown-identities'", NULL, NULL, NULL);
		if (execResult != SQLITE_OK) NSLog(@"Failed to exec DELETE FROM cert WHERE agrp <> 'lockdown-identities', error %d", execResult);

		execResult = sqlite3_exec(database, "DELETE FROM keys WHERE agrp <> 'lockdown-identities'", NULL, NULL, NULL);
		if (execResult != SQLITE_OK) NSLog(@"Failed to exec DELETE FROM keys WHERE agrp <> 'lockdown-identities'', error %d", execResult);

		execResult = sqlite3_exec(database, "DELETE FROM inet", NULL, NULL, NULL);
		if (execResult != SQLITE_OK) NSLog(@"Failed to exec DELETE FROM inet, error %d", execResult);

		execResult = sqlite3_exec(database, "DELETE FROM sqlite_sequence", NULL, NULL, NULL);
		if (execResult != SQLITE_OK) NSLog(@"Failed to exec DELETE FROM sqlite_sequence, error %d", execResult);

		sqlite3_close(database);
	}

你好，我把Keychains文件夹下的所有文件和子目录都删除了，应该怎么恢复啊？还是说有什么方法自动生成啊

嗯，谢谢，重启后的确自动生成了

我刚才试了一下我的设备，iphone5c+ios9.0系统删除掉/var/Keychains下的文件后，重启之后wifi密码之类的确实没有了；但是另一台设备，iphone5+ios8.3删除掉后重启，并没有重新生成，一些密码还是有效的。
请问是系统差别导致的吗？

请问解决了吗

我写了一个root级别的app, 但是代码中删除不成功, 非要写成脚本, 放到手机里, 才能删除成功

大佬 这个有点点不足之处 是全部清掉 无法指定app https://github.com/393101641/ios10_keybag_clear希望对后来者有帮助
