Application of 1:FCUUID Acquisition equipment identification

A: Author Githun address Https://github.com/fabiocaccamo/FCUUID

Because it also uses the author's other class Uickeychainstore address: Https://github.com/kishikawakatsumi/UICKeyChainStore

B: Add security.framework to the project

C: Import header file #import "FCUUID.h"

// each run of the app will change the + (NSString *) uuid; // changes each time (no persistent), but allows to keep in memory more temporary UUIDs+ (NSString *) Uuidforkey: (ID&L T nscopying>) key; // each run of the application will change the + (NSString *) uuidforsession; // re-install will change + (NSString *) uuidforinstallation; // Reload will change after unloading (NSString *) Uuidforvendor; // Erase the iphone will only change, suitable for a unique logo + (NSString *) Uuidfordevice;

2: Add a peripheral white border to the picture

-(uiimage*) Circleimage: (uiimage*) Image withparam: (cgfloat) inset {//Uigraphicsbeginimagecontext (image.size); //solve the problem of distortion bluruigraphicsbeginimagecontextwithoptions (Image.size, NO, [[UIScreen mainscreen] scale]); Cgcontextref Context=Uigraphicsgetcurrentcontext (); //the border width of the circle is 2 and the color is redcgcontextsetlinewidth (Context,2); Cgcontextsetstrokecolorwithcolor (context, [Uicolor Whitecolor].        Cgcolor); CGRect rect= CGRectMake (inset, inset, Image.size.width-inset *2.0f, Image.size.height-inset *2.0f);        Cgcontextaddellipseinrect (context, rect);        Cgcontextclip (context); //draw the image in the circle area[Image Drawinrect:rect];        Cgcontextaddellipseinrect (context, rect);        Cgcontextstrokepath (context); //generate a new imageUIImage*newimg =Uigraphicsgetimagefromcurrentimagecontext ();        Uigraphicsendimagecontext (); returnnewimg; }

Note: If you use Uigraphicsbeginimagecontext (image.size), it can cause the picture to be a bit distorted and blurry, using uigraphicsbeginimagecontextwithoptions ( Image.size, NO, [[UIScreen mainscreen] scale]) and if you draw a circle on a view, you can see it only if the view is not covered by other, such as if there is a background image, then it is not covered;

3: Package A uinavigation in the normal view controller

#pragmaMark adds a navigation bar-(void) addnavigationbar{//Create a navigation barUinavigationbar *navigationbar=[[uinavigationbar Alloc]initwithframe:cgrectmake (0,0, the, -+ -)]; //Navigationbar.tintcolor=[uicolor Whitecolor];[Self.view Addsubview:navigationbar]; //creating navigation control contentUinavigationitem *navigationitem=[[uinavigationitem Alloc]initwithtitle:@"Web Chat"]; //Add Login button to the leftUibarbuttonitem *loginbutton=[[uibarbuttonitem Alloc]initwithtitle:@"Login"Style:uibarbuttonitemstyledone target:self Action: @selector (login)]; Navigationitem.leftbarbuttonitem=Loginbutton; //add content to the navigation bar[Navigationbar Pushnavigationitem:navigationitem animated:no];}

4: The system comes with positioning coordinates to the city name

    //system comes with the positioning[[Mplocationmanager Shareinstance] startsystemlocationwithres:^ (cllocation *loction, NSError *error) {        if(!error) {Clgeocoder*geocoder=[[Clgeocoder alloc]init]; [Geocoder reversegeocodelocation:loction Completionhandler:^ (Nsarray<clplacemark *> * _nullable placemarks, Nserror *_nullable Error) {                if(placemarks.count>0) {Clplacemark*placemark=[placemarks Objectatindex:0]; //get the cityNSString *city =placemark.locality; if(!City ) {                        //the city information of the four municipalities can not be obtained by locality, but only by obtaining the province's method (if it is empty, it is known as the municipality)City =Placemark.administrativearea; }                    //there are differences before they change .                    if(![bbuserdefault.locationcity isequaltostring:city]) {bbuserdefault.locationcity=City ; } NSLog (@"current City: [%@]", city);        }            }]; } bbuserdefault.latiude=[nsstring stringWithFormat:@"%f", Loction.coordinate.latitude]; Bbuserdefault.longitude=[nsstring stringWithFormat:@"%f", Loction.coordinate.longitude]; NSLog (@"positioning information: [%f,%f]", Loction.coordinate.latitude,loction.coordinate.longitude); }];

Note:the code for the MPLocationManager.h class is as follows:

#import <Foundation/Foundation.h>void(^ksystemlocationblock) (Cllocation *loction, Nserror *error); @interface mplocationmanager:nsobject+ (id) shareinstance; /* * *   Start System location * *  /-(void) Startsystemlocationwithres: (Ksystemlocationblock) Systemlocationblock; @end
