iphone - How to call function in every "X" minute? -

-

I was trying to create a sample iPhone application to update the current location. I have a function that logs to the current location, "Log content location", but I do not know how to call these functions automatically in each x minute (or seconds).

Please advise me which method I need to see in the apple document

Thank you for your help.

See the document for NSTimer. This allows you to schedule a timer that will call the function (defined by the "target" object and a "selector" that you want to call). You can change the interval on which the timer starts to fire, and this should do the trick!

Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never...
