+(id)stringWithCString:(const char *)cString encoding:(NSStringEncoding)enc

I think you'll typically use NSUTF8StringEncoding, so your code would look like

keyFromSq1 = [NSString stringWithCString:(char *)sqlite3_column_text(preparedStatement, 1) encoding:NSUTF8StringEncoding];

Alternatively you can use

keyFromSq1 = [NSString stringWithUTF8String:(char *)sqlite3_column_text(preparedStatement, 1)];

Since SQLite always return UTF-8* encoded strings, you could just use +stringWithUTF8String:.

const char* res = (const char*)sqlite3_column_text(preparedStatement, 1);keyFromSql = [NSString stringWithUTF8String:res];

_{(* or UTF-16, if you use sqlite3_column_text16)}

[[NSString alloc] initWithBytes:bytes length:count encoding:NSUTF8StringEncoding]is preferred to stringWithCString:encoding:

Apple's Document's recommendation is not very OK, because the original method "doesn’t stop short at a NULL character."
