偶现的在调用isTableExists方法时，崩溃。

[JabberYQ]

db的初始化：

NSString *dbPath = [NSString stringWithFormat:@"%@/user_%@_db.sqlite", [NMYFileManager appDataDocumentDir],self.currentId];
self.currentDB = [[WCTDatabase alloc] initWithPath:dbPath];

判断表是否存在的代码：

+ (NSString *)tableName {
    return @"NMYSessionUserModel";
}

+ (BOOL)exsitTable {
    return [NMYDBStorage.share.dataBase isTableExists:NMYSessionUserModel.tableName];
}

Please use WCDB 2.0 and see if there is still this problem.
