Foreign third party sharing, including Facebook,twitter,instagram

1.facebook, Twitter, etc.

With the iphone's own sharing, first import social.framework, and then import

#import <Social/Social.h> End With the following code to complete the share:

Slcomposeviewcontroller *COMPOSEVC = [Slcomposeviewcontroller composeviewcontrollerforservicetype:sharedname];

BOOL success = [COMPOSEVC setinitialtext:self.sharedcontent];//share content

BOOL imagesuccess = [COMPOSEVC addimage:self.sharedimage];//share picture

Callback

Slcomposeviewcontrollercompletionhandler Myblock = ^ (Slcomposeviewcontrollerresult result) {

if (result = = slcomposeviewcontrollerresultcancelled) {

NSLog (@ "cancelled");

}else{

NSLog (@ "Post");

}

[Composevc Dismissviewcontrolleranimated:yes Completion:nil];

};

Composevc.completionhandler = Myblock;

if (Success && imagesuccess)

[Self PRESENTVIEWCONTROLLER:COMPOSEVC animated:yes completion:nil]; }
2.Instagram a little trouble, through the Uidocumentinteractioncontroller to complete the sharing, first of all, we must first determine whether the existence of Instagram, if there is a sharing of the operation. The code is as follows:

-(void) Instagramshare: (uiview*) view{

uiimage* image = [UIImage imagenamed:@ "csh.jpg"];//shared pictures

CGFloat cropval = (Image.size.height > image.size.width? image.size.width:image.size.height);

Cropval *= [Image scale];

CGRect croprect = (cgrect) {. Size.Height = Cropval,. size.width = Cropval};

Cgimageref imageref = Cgimagecreatewithimageinrect ([Image cgimage], croprect);

NSData *imagedata = uiimagejpegrepresentation ([uiimage imagewithcgimage:imageref], 1.0);

Cgimagerelease (IMAGEREF);

NSString *writepath = [Nstemporarydirectory () stringbyappendingpathcomponent:@ "Instagram.igo"];

if (![ ImageData Writetofile:writepath Atomically:yes]) {

Failure

NSLog (@ "image save failed to path%@", Writepath);

Return

} else {

Success.

}

Send it to Instagram.

Nsurl *fileurl = [Nsurl Fileurlwithpath:writepath];

Self.documentcontroller = [Uidocumentinteractioncontroller Interactioncontrollerwithurl:fileurl];

Self.documentController.delegate = self;

[Self.documentcontroller setuti:@ "Com.instagram.exclusivegram"];

[Self.documentcontroller setannotation:@{@ "instagramcaption": @ "My Love Dyl"}];

CGRect rect = CGRectMake (0, 0, 0, 0);

Uigraphicsbeginimagecontextwithoptions (View.bounds.size, View.opaque, 0.0);

[View.layer Renderincontext:uigraphicsgetcurrentcontext ()];

Uigraphicsendimagecontext ();

[Self.documentcontroller presentopeninmenufromrect:rect Inview:view Animated:yes];

}
