Question

我在我的iOS项目中使用Sqlite（sqlcipher）来存储数据库。在iOS 9中，所有东西都运行得很好。现在我更新了新的Xcode。但是DB加密现在还不行。

sqlite3 *db1;
    if (sqlite3_open([[self.databaseURL path] UTF8String], &db1) == SQLITE_OK) {
        const char* key = [g_sqlite_key UTF8String];
        AZLog(@"%s",key);
        sqlite3_key(db1, key, (int)strlen(key));
        if (sqlite3_exec(db1, (const char*) "SELECT count(*) FROM sqlite_master;", NULL, NULL, NULL) == SQLITE_OK) {
            AZLog(@"Password is correct, or a new database has been initialized");
        } else {
            AZLog(@"Incorrect password!");
        }
        sqlite3_close(db1);
    }

任何人都可以帮助我吗？

提前致谢

使用sqlcipher加密数据库时，必须提供readwrite和open-create权限。

sqlite3 *db1;
    if (sqlite3_open_v2([[self.databaseURL path] UTF8String], &db1, SQLITE_OPEN_READWRITE | SQLITE_OPEN_CREATE, NULL) == SQLITE_OK) {
        const char* key = [g_sqlite_key UTF8String];
        AZLog(@"%s",key);
        sqlite3_key(db1, key, (int)strlen(key));
        if (sqlite3_exec(db1, (const char*) "SELECT count(*) FROM sqlite_master;", NULL, NULL, NULL) == SQLITE_OK) {
            AZLog(@"Password is correct, or a new database has been initialized");
        } else {
            AZLog(@"Incorrect password!");
        }
        sqlite3_close(db1);
    }

Xcode 8和新SDK有很多变化。请参阅本指南：
