Undefined symbols for architecture armv7s:

Question

So I am trying to implement this into my current project:

https://github.com/mobitar/MBAlertView

Wenn I try to use this in my app I get this error:

Answer 1

Unless you are writing a high performance game and write in assembly, just turn off the armv7s architecture in the build settings. This doesn't make any difference for normal apps (it's the processor in the iphone5).

Answer 2

You just look at following questions that may help you

Answer 3

I have downloaded MBAlertView repository than compiled the example project and it worked. After that i have added MBAlertView directory to my project and it started to work after i added QuartzCore.framework in Link Binary With Librarys section of Build Phases in project file.
