VCF, a format for address book export.

One. Generate VCF File

Suppose you want to generate the VCF format file for the data in our iphone address Book.

We can help with icloud.

Tips: How to export iphone contacts via icloud of course, suppose you want to use code generation in your app, and you can. Pilot out the Address book data, then parse, and then generate the VCF file can be.

Refer to the following code:

Parse VCF file

Use Uidocumentinteractioncontroller to show this file with Quicklook.

Then he will parse it on his own initiative and have the Add to Address Book option.

Of course. We are also able to parse it ourselves.

Detailed code such as the following:

Parsing vcf-(void) parsevcardstring: (nsstring*) vcardstring{nsarray *lines = [vcardstring componentsseparatedbystring:@]        \ n "];         for (nsstring*. Lines) {if ([line hasprefix:@ "BEGIN"]) {NSLog (@ "parse start");        } else if ([Line hasprefix:@ "End"]) {NSLog (@ "Parse END"); } else if ([line hasprefix:@ ' N: "]) {nsarray *uppercomponents = [Line componentsseparatedbystring            :@":"];                        Nsarray *components = [[uppercomponents objectatindex:1] componentsseparatedbystring:@ ";"];            NSString * LastName = [Components objectatindex:0];                        NSString * FirstName = [Components objectatindex:1];                    NSLog (@ "name%@%@", lastname,firstname);        } else if ([line hasprefix:@ "EMAIL;"])            {Nsarray *components = [Line componentsseparatedbystring:@ ":"]; NSString *emailaddress = [Components objectatindex:1];                    NSLog (@ "EmailAddress%@", EmailAddress);        } else if ([line hasprefix:@ "TEL;"])            {Nsarray *components = [Line componentsseparatedbystring:@ ":"];            NSString *phonenumber = [Components objectatindex:1];        NSLog (@ "PhoneNumber%@", PhoneNumber); }    }    }
