xcode - How to figure out what caused runtime error on IPhone App? -

-

In the xcode, say that you write an app for the iPhone and it has a runtime error in what I'm looking for I am that it closes the program in the simulator, but in reality I do not get any response or not, which line is the accident from me ... am I missing something ??

Note: I do not consider the console to be very effective because it only presses an error, but still I have to find out where that bug is from that code.

In the console, above the stack trace, to the unknown selector by the name "classname namefalc" for example should be sent. "

Make sure that you really wanted to send that selector to that class. If you post what it is, then we can help you more than that.

To reach GDB, enable breakpoint, click on the line number gutter and add one to your code, build and press debug and finally open Debugger (CMD + Shift + Y).

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
