LD can ' t link with a main executable file for architecture armv7

Running on the iphone 6 Plus ran the error: LD can ' t link with a main executable file for Architecture armv7, and then change it, because I have already added arm64 to the luxury Lunch lineup, why do you also remind me not to allow running on the 64-bit processor? This is unscientific!

Then there are all kinds of Google Bai, hmm, found two solutions:

First, Http://stackoverflow.com/questions/26031932/cant-link-with-a-main-executable-file

The simple way:

1. Select your project

2. Then select your test target

3. Set the host application on the right to your project name

Second, http://blog.csdn.net/ggbb190/article/details/41701343

If that doesn't work, you can refer to this, architectures, Build Active Architecture only option, set to No

Then clean it again and run it again.
