Get your phone's contact list and call

To get a list of contacts in your phone, you need to use the framework provided to us by the system: Addressbook.framework,

1. Import the framework;

2. CV model and manager:

Model:

. h

#import <Foundation/Foundation.h>@interface**phone; + (Instancetype) Contactwithitem: (ID) item; -(Instancetype) Initwithitem: (ID) item; @end

. m

#import "Contact.h"#import<AddressBook/AddressBook.h>@implementation Contact+ (Instancetype) Contactwithitem: (ID) item{return[Contact Alloc] initwithitem:item];}-(Instancetype) Initwithitem: (ID) item{ Self=[Super Init]; if(self) {nsstring*temfirstname = (__bridge NSString *) Abrecordcopyvalue ((__bridge abrecordref) (item), kabpersonfirstnameproperty); NSString*temlastname = (__bridge NSString *) Abrecordcopyvalue ((__bridge abrecordref) (item), kabpersonlastnameproperty); Abmultivalueref Tempphones=Abrecordcopyvalue (__bridge abrecordref) (item), kabpersonphoneproperty); Self.name= [NSString stringWithFormat:@"%@%@", Temlastname?temfirstname:@"", Temfirstname?temlastname:@""]; Self.phone= (__bridge NSString *) Abmultivaluecopyvalueatindex (Tempphones,0); }        returnSelf ;}@end

Managers:

. h

#import <Foundation/Foundation.h>@interface  contactmanger:nsobject-( Instancetype) Initwitharray: (Nsarray *) contacts; -(Nsdictionary *) Contactswithgroup; @end

. m

#import "ContactManger.h"#import "Contact.h"@interfaceContactmanger () @property (nonatomic, strong) Nsarray*mycontacts, @property (nonatomic, strong) Nsmutabledictionary*Contactsdic;@end@implementationContactmanger+ (NSString *) Phonetic: (NSString *) sourcestring{nsmutablestring*source =[sourcestring mutablecopy];    Cfstringtransform ((__bridge cfmutablestringref) source, NULL, Kcfstringtransformmandarinlatin, NO);    Cfstringtransform ((__bridge cfmutablestringref) source, NULL, Kcfstringtransformstripdiacritics, NO); returnsource;}-(Instancetype) Initwitharray: (Nsarray *) contacts{ Self=[Super Init]; if(self) {_mycontacts=contacts; }        returnSelf ;}-(Nsdictionary *) contactswithgroup{ for(IDIteminch_mycontacts) { Contact*people =[Contact Contactwithitem:item]; if(! [People.name isequaltostring:@""]) {nsstring*nameenglish =[Contactmanger Phonetic:people.name]; Nameenglish=[Nameenglish capitalizedstring]; Unichar k= [Nameenglish Characteratindex:0]; if(! (k >='A'&& k <='Z') ) {k='#'; } nsstring*key = [NSString stringWithFormat:@"%c", K]; Nsmutablearray*ARRAYGROUPK =[Self.contactsdic Objectforkey:key]; if(!ARRAYGROUPK) {ARRAYGROUPK= [[Nsmutablearray alloc]initwithcapacity:5];                                [ARRAYGROUPK Addobject:people]; if(Nil = =self.contactsdic) {self.contactsdic= [[Nsmutabledictionary alloc]initwithcapacity:5];                                            } [Self.contactsdic setobject:arraygroupk Forkey:key]; }Else{[ARRAYGROUPK addobject:people]; }        }                    }                returnSelf.contactsdic;}@end
