objective-c - “仅显示 Obj-c”标志隐藏 xCode Instruments 上调用树的所有内容

Question

Ok, I don`t really know what happens here, but now it works. How?

What I did:

• Erase the app in the device
• Kill xCode ( using activity monitor )
• Restart the computer ( Only restarting xcode didn't work )
• Restart the device.
• Clean the project
• Try again.

May be is not the best answer, but it worked for me.

[UPDATE] The issue is there again, so I try this: Xcode 4 Instruments doesn't show source lines

And it works!
