app terminating suddenly without giving any exception in console in iphone

i have a problem while building and running an iphone application.Im using xml parsing to get data and storing it in core data.From there im retrieving data to display in a table.As i di开发者_C百科d this,seems to be working becoz im able to display it in the table as well as in a console but the app was terminating suddenly without leaving any exception in console.I thought it may be becoz of not releasing any object and thouroghly checked it out.but everything is gud.Could u please let me know why this has been happening?

You should use the NSZombie. It will show you the exact problem in console.
