First, I have installed cocoapods correctly, because I can install AFNetworking. Second, Although I am in China, I have tried VPN. Third, In my Podfile, I just write pod 'OpenCV'

I know I can use OpenCV without cocoapods, but I still want to solve this problem.

Is a bad question? I have not clue yet.

OpenCV is hosted by Sourceforge, which seems to be unreliable for these kind of hard-coded links.

As an alternative, here are a couple of self-hosted podspecs for 2.4.9 and 2.4.10 that you should be able to use:

https://github.com/Zi0P4tch0/Specs/tree/master/Specs/OpenCV

Your podfile should look something like this:

source 'https://github.com/Zi0P4tch0/Specs.git'

platform :ios, '7.0'

pod 'OpenCV', '2.4.9-zp'

These were set up to support my OpenCVSwiftStitch demo project, as I couldn't get the official podspec paths to work.

In my experience 2.4.10 is broken anyway, so 2.4.9 is the preferred option.

3.0.0 also seems to be fine as manual download. No podspec, but the framework available from (http://openCV.org) just worked for me when I dragged it into the SwiftStitch project.

A temporary work-around is to edit the local pod spec with

pod spec edit opencv

and replace the no longer valid download URL with

http://garr.dl.sourceforge.net/project/opencvlibrary/opencv-ios/2.4.10/opencv2.framework.zip

and wait until the pod gets fixed. Ideally - open an issue for it.

the --show-all option may come in handy so that you edit the podspec for the version you are trying to install.
