iPhone simulator keeps app running on Build and Run

I have a problem w开发者_运维问答ith my iPhone simulator. Since yesterday when I press Build and run.

• Xcode builds the project
• Simulator closes the running app
• Simulator opens the running app in same state as it closed (multitasking?)

The old build keeps running, I have to quit the simulator before i can run the new build. I tried cleaning the project, tested with a new project. Same problem. Rebooted everything.

Running Xcode 3.2.4 / 4.1 SDK.

I was going crazy with the same problem. It seems that some people have this problem and some don't. Somehow I stumbled onto this: http://openradar.appspot.com/8915498

Basically, it says that if you're running the iPhone simulator on a different volume than the xCode app, there is some problem with updating the simulator and you have to restart each time.

I almost ignored the fix because I only use one volume, but I DO use filevault for my home folder. Since the Library/Application Support/iPhone Simulator was in my /Users/[me] directory, I guess it's a different volume.

So, what I did was:

1) Go to /Users/[Me]/Library/Application Support/iPhone Simulator and renamed to "old-iPhone Simulator" (just to get it out of the way without deleting)

2) Go to /Library/Application Support and create a new folder called "iPhone Developer"

3) Open Terminal and enter: ln -s "/Library/Application Support/iPhone Simulator" "/Users/[Me]/Library/Application Support/iPhone Simulator"

Viola! Worked like a charm for me! Now iPhone simulator shows me the changes I make every time I push "Build and Run" without any other hassles! Yay! 3)

I added a Run Script to my target to work arround the issue

killall -9 "iPhone Simulator"

Not a proper fix, but works for now.
