If you expand the Breakpoints section in the Groups & Files pane, you'll find two further subdirectories - Project Breakpoints and Global Breakpoints. Assuming that the breakpoints set are specific to your current project, your breakpoints will be listed under Project Breakpoints. Right click on this directory and select Disable Breakpoints from the context menu, which will disable all the breakpoints for your project.
Useful shortcut is "command y" to disable all the break point. You can toggle this command to disable/enable all breakpoints. This is for Xcode 4.x version.
