IOS8 new feature extension (Extension) Application II-Share plugin

in the previous blog, we introduced the Today feature of IOS8, one of the features of the new feature extension: http://my.oschina.net/u/2340880/blog/485533, where we'll look at the extended functionality of sharing.

Before iOS8, in addition to some of the mainstream social platforms, such as Apple's support for content sharing, other developers ' apps would be very complex to add to the shared functionality. In the new features of IOS8, Apple has prepared such extensions for us.

Start by creating a project and create a new target in our project:

After that, a controller class is created for us in the template that controls our share plugin, which includes:

@implementation  shareviewcontroller//This function is used to determine the availability of shared content, in which we get shared content to check-  (BOOL) iscontentvalid {     // Do validation of contentText and/or  Nsextensioncontext attachments here    return yes;} After clicking the Post button, we can upload the contents of the-  (void) didselectpost {    // this  is called after the user selects Post. Do the upload  of contenttext and/or nsextensioncontext attachments.         // inform the host that we ' Re done, so it un-blocks  its ui. note: alternatively you could call super ' s - didselectpost, which will similarly complete the extension context.     [self.extensioncontext completerequestreturningitemS:@[] completionhandler:nil];} This is used to set the share plugin's attachment button-  (nsarray *) Configurationitems {    // to add  configuration options via table cells at the bottom of the  sheet, return an array of SLComposeSheetConfigurationItem here.     return @[];} @end

In addition, there are some common properties:

-(void) presentationanimationdidfinish;

Methods to execute after the pop-up view animation finishes

@property (readonly, ns_nonatomic_iosonly) NSString *contenttext;

Content text to share

@property (copy, ns_nonatomic_iosonly) NSString *placeholder;

Prompt text displayed by default

-(void) didselectcancel;

How to cancel a button execution

We'll run it in the code after adding the following:

@implementation shareviewcontroller-(NSString *) placeholder{return @ "hint text";}  -(Nsarray *) Configurationitems {//To add configuration options via table cells in the bottom of the sheet, return an    Array of Slcomposesheetconfigurationitem here.    Slcomposesheetconfigurationitem * Item =[[slcomposesheetconfigurationitem Alloc]init];    [Email protected] "location";    [Email protected] "Shing Mun"; return @[item];}

We use the System photo album to do the test, click the photo sharing button:

Click More to add our extensions.

Then there is one more of our plugin in the Sharing bar, click the effect as follows:

There is one more thing we need to understand, in this extended plist file, there is a key: Nsextensionattributes, there is a nsextensionactivationrule dictionary, where you can set some key values, Controls the properties of the share plugin.

The wording of these keys is described in the official documentation as follows:

The meanings of these keys are clearly described in the documentation and can be set as needed.
