"Learning the path of iOS: UI series" To make calls, send text messages, send email functions

① Texting

1. Create a button to add a button response event

  UIButton *callbutton = [UIButton buttonwithtype:uibuttontypecustom];  Callbutton.frame = CGRectMake (on the other);  Callbutton.backgroundcolor = [Uicolor cyancolor];  [Callbutton settitle:@ "SMS" forstate:uicontrolstatenormal];  [Callbutton addtarget:self Action: @selector (callbuttonaction:)                                        Forcontrolevents:uicontroleventtouchupinside] ;  [Self.view Addsubview:callbutton];

2. Send SMS operation, set agent Mfmessagecomposeviewcontrollerdelegate

-(void) Callbuttonaction: (UIButton *) msg2{    //Determine if the user device can send SMS    if (![ Mfmessagecomposeviewcontroller Cansendtext]) {        return;    }        1. Instantiate a controller    mfmessagecomposeviewcontroller *controller =                                     [[Mfmessagecomposeviewcontroller alloc] init];    2. Set SMS Content    //1) recipient    controller.recipients = @[@ "10010", @ "10086"];        2) SMS content    controller.body = @ "Happy!" ";        3) Set proxy    controller.messagecomposedelegate = self;        3. Display SMS Controller    [self presentviewcontroller:controller animated:yes completion:nil];}

3. Implementing Proxy Methods

/** SMS Send results messagecomposeresultcancelled,     cancel Messagecomposeresultsent,          send messagecomposeresultfailed         Failure */-(void) Messagecomposeviewcontroller: (Mfmessagecomposeviewcontroller *) controller                                    Didfinishwithresult: ( Messagecomposeresult) result{    NSLog (@ "%d", result);        In object-oriented programming development, there is a principle, who applies, who releases!    //* * * This method also works because the system sends a shutdown message to self    //    [controller Dismissviewcontrolleranimated:yes Completion:nil];        You should use this!    [self Dismissviewcontrolleranimated:yes completion:nil];}

② e-mail

1. Create button (above), Set button trigger event, Emailbuttonaction: Implementation method

<span style= "color: #000000;" >-(void) Emailbuttonaction: (UIButton *) SendMail {//1. First determine if the message can be sent if (![ Mfmailcomposeviewcontroller Cansendmail]) {//Prompt user to set mailbox Uialertview *alert = [[Uialertview alloc] In                                        Itwithtitle:nil   message:@ "user does not have a mail account set up" Delegate:self Cancelbuttontitle:nil         otherbuttontitles:@ "OK", nil];        [Alert show];         [Alert release];    Return }//2.        Instantiate the mail controller, ready to send mail Mfmailcomposeviewcontroller *controller =[[mfmailcomposeviewcontroller alloc] init];    1) Topic XXX Work Report [Controller setsubject:@ "project reply"];        2) Recipient [Controller settorecipients:@[@ "[email protected]"];        5) The body [controller setmessagebody:@] is the justice "Ishtml:yes";    6) Accessories UIImage *image = [UIImage imagenamed:@ "Avatar 1.png"];     NSData *imagedata = uiimagepngrepresentation (image); 1> binary data for attachments//3> The name of the file that the recipient sees when receiving the//can add multiple attachments [controller AddattAchmentdata:imagedata mimetype:@ "Image/png" filename:@ "Avatar. png"];        7) Set agent [controller setmailcomposedelegate:self]; Display controller [self Presentviewcontroller:controller animated:yes completion:nil];} </span>

2. Implementing the Proxy Method (Mfmailcomposeviewcontrollerdelegate)

-(void) Mailcomposecontroller: (Mfmailcomposeviewcontroller *) controller                Didfinishwithresult: ( Mfmailcomposeresult) Result Error: (Nserror *) error{    //Prompt user NSLog according to different status    (@ "%d", result);        [Self Dismissviewcontrolleranimated:yes completion:nil];}

③ Call

1. Method 1

-(void) tel2{    //However: the Telprompt protocol belongs to Apple's private agreement, and once this protocol is used in the program, the program cannot be on the shelves    /system developed for jailbroken machines, you can use this protocol    nsurl *url = [Nsurl urlwithstring:@ "telprompt://10010"];        [[UIApplication sharedapplication] openurl:url];}

2. Method 2 (recommended)

@property (nonatomic, retain) UIWebView *webview;

Implementing Response Events

-(void) Phonebuttonaction: (UIButton *) tel3{    //Hint: Do not add webview to Self.view if added will obscure the original view    //Lazy Load If    (_ WebView = = nil) {        _webview = [[UIWebView alloc] init];    }    NSLog (@ "%p", _webview);    _webview = [[UIWebView alloc] initWithFrame:self.view.bounds];    [Self.view Addsubview:_webview];        Nsurl *url = [Nsurl urlwithstring:@ "tel://10010"];    Nsurlrequest *request = [Nsurlrequest requestwithurl:url];    UIWebView *view = [[UIWebView]    [_webview loadrequest:request];    }

3. This method, call the end of the phone back to the original application, will stay in the address book, and is directly dialed, do not pop-up hints.

Nsmutablestring * str=[[nsmutablestring alloc] initwithformat:@ "tel:%@",                       @ "186xxxx6979"];[ [UIApplication sharedapplication] Openurl:[nsurl Urlwithstring:str]];
