Writing in the front

Some time ago, I set up chevereto-free, a map bed website, with my friends. Suddenly, I found that there is an API to provide, and it is very simple, just need a KEY

Feel very suitable for practice when the project, not a few pages, do very fast, is 2.1 gift package made for a long time before the online. Mimi tobed AppStore

Small blog with friends interested can see, this article will also be synchronized in the past, also contains some server related content. Personal blog

This article mainly code using RAC+MVVM and some other third-party libraries, do more urgent, although it is MVVM+RAC but the use of the relatively poor, do not like spray. Code structure is not paid special attention to

The preparatory work

You have to have a VPS
Install the relevant environment, visual pagoda set is good, or directly install the LNMP environment
Build chevereto-free front and back

Install the front and back of the map bed can use a normal Web site to upload pictures. Go in the background and open the API and get the API KEY

This is the mimitu bed after it’s built

Manage third parties using cocoaPods. Turn on iCloud’s simplest key-value storage feature

Interface design

After all the preparation work is done, we can start to design the App. Don’t get too complicated. Just a few pages

Home page: main function entrance, upload pictures. After uploading, you can choose the content of copy and add a share
History: Uploaded history, directly using iCloud to save data. There are also home copy and share functions
About: some disclaimer, for example prohibit upload small yellow map and so on.

Lazy direct screenshots

Home page

Home page is a upload image to the background, stole a lazy, did not use RAC+MVVM, directly a pile of written in VC

The first page is basically over… One VC. Post it just for space.

history

The basic functions are as follows

Load iCloud data

Delete records

share

MVVM+RAC is used here

ViewModel Creates two commands, retrieves data, and deletes data

@interface MMHistoryViewModel : GBaseViewModel
@property (nonatomic, strong, readonly) RACCommand *getMainData;
@property (nonatomic, strong, readonly) RACCommand *deleteCommand;
@end
