Summary of November 10th – Preliminary report & Programming on opening camera

Logbook noting:

In Week 5, I mainly searched the information about how to open the camera and how to select a photo in the iPhone.

In week 6, I tried to follow the tutorial videos and wrote the Xcode to select picture in an iPhone.

In the following picture, the Xcode of the program is shown. The upper half of the codes realize the function in order to set up a button leading to selecting picture in the phone.

The next four fictures show how the program goes.

Figure 5: Pick a picture

As for the second part of the codes, I tried to open the rare camera of a phone. But I was informed that the simulator could not open a camera, the camera could only be opened when the Mac is connected with an iPhone.

The main mission for the next week is to connect a real iPhone with the Mac and be able to test the code using the real iPhone

Comments:

During the week 5, I spent much time on my preliminary report. In that report, I mainly introduced the background of collision warning system, methodologies I would use in this project, timetable of this project, objectives and some initial results.

From the middle of week 6, I turned back on Xcode and tried to learn how to open camera of an iPhone. By that time I didn’t know that if I want to simulate an APP on a real device, I have to apply a licence from apple and add my iPhone device to developer team. I even tried to connect my iPhone with the Mac in our lab, of course, with no reaction reply.

But this try indeed pushed me to handle my project. From these codes I got in touch with apple application developing. This kind of way to learn how to do something or realise some functions became my first choice in following steps and it helped a lot.
