Analysis of iOS development: "secret" App content page effect (2), iosapp

@ I wrote a "secret" Cell effect article a few days ago, but there is still a gap with the desired effect at work, and the scalability is poor, so I rewrite the encapsulation, put the overall view into the scrollView, which is basically the same effect as the secret app.

@ The Code is as follows: (the fuzzy effect class will not be written. You can search for "UIImage + ImageEffects" and import Accelerate. framework)

1. MTSecretAppEffect. h

# Import <Foundation/Foundation. h> @ interface MTSecretAppEffect: NSObject/*** creates an overall scrollView and loads headScrollView and tableView on it to slide up and down, all other slides are not allowed ** @ return mainScrollView */-(UIScrollView *) createMainScrollView;/*** create headScrollView ** @ return headScrollView */-(UIScrollView *) createHeadScrollView; /*** create a Fuzzy view of the header ** @ param scrollview headScrollView ** @ return blurImageView */-(UIImageView *) createBlurImageViewOfView :( UIScrollView *) scrollview; /*** in-(void) scrollViewDidScroll :( UIScrollView *) method called in scrollView ** @ param scrollView * @ param mainScrollView * @ param tableView * @ param headScrollView * @ param blurImageView */-(void) scrollDidScrollView :( UIScrollView *) scrollView withMainScrollView :( UIScrollView *) mainScrollView withTableView :( UITableView *) tableView withHeadScrollView :( UIScrollView *) headScrollView withBlurImageView :( UIImageView *) blurImageView @ end

2. MTSecretAppEffect. m

During ios development and application submission, the development certificate and the App IDs

1. Develop a certificate for development and install it on a mac computer.
2. if you want to perform a real machine test, you need a profile and register the device you used for the test in this profile (A Personal Development Account can register 100 devices). This profile can be generated on the official website, and download it to the local machine.
3. If you want to publish data to the app store, your program requires an app id. Each program corresponds to an app id. In addition, you need to bind a release profile to the app id. The app id indicates the special functions required by your program, such as push and icowould. The app id must be indicated in the bundle settings of the program. The name must be the same as that on the Internet.
I have released several programs. The above are regular channel releases and no cracking releases. They are for reference only and hope they can help you.

How to obtain the app list in ios development

The APIS published by Apple cannot obtain the list of installed apps. Unless it is a private api, it cannot be approved by Apple.
