如何從設備獲取發件人電子郵件？

Question

我從我的應用程序發送一些數據到服務器。如下圖所示

-(void)createXML 
{ 
xmlStr = @"<?xml version='1.0'?>\n<jand_req>\n<inquiryList>\n<productArr>\n"; 
NSString *nameStr=[NSString stringWithFormat:@"<name>%@</name>\n",name.text]; 
xmlStr=[xmlStr stringByAppendingString:nameStr]; 
NSString *compNameStr=[NSString stringWithFormat:@"<comp_name>%@</comp_name>\n",compName.text]; 
xmlStr=[xmlStr stringByAppendingString:compNameStr]; 
NSString *cityStr=[NSString stringWithFormat:@"<city>%@</city>\n",city.text]; 
xmlStr=[xmlStr stringByAppendingString:cityStr]; 
NSString *countryStr=[NSString stringWithFormat:@"<country>%@</country>\n",[nameToCode objectForKey:country.text]]; 
xmlStr=[xmlStr stringByAppendingString:countryStr]; 
NSString *commentsStr=[NSString stringWithFormat:@"<comment>%@</comment>\n",commentsBox.text]; 
xmlStr=[xmlStr stringByAppendingString:commentsStr]; 
xmlStr=[xmlStr stringByAppendingString:@"</userDetail>\n</inquiryList>\n</jand_req>"]; 
} 

我的代碼，在這之後我的數據由不同領域的我上面的數據發送到服務器如下圖所示

- (void)submitForm 
{ 
[self createXML]; 

NSLog(@"myaccesscode%@",[fn getValFromSettings:@"accessCode"]); 
    NSString *serviceUrlStr=[NSString stringWithFormat:@"%@/%@/API_sendmail.php?access_code=%@",domainName,apiFolderPath,[fn getValFromSettings:@"accessCode"]]; 
    NSLog(@"%@",serviceUrlStr); 
    NSURL * serviceUrl = [NSURL URLWithString:[serviceUrlStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; 
    NSMutableURLRequest * serviceRequest = [NSMutableURLRequest requestWithURL:serviceUrl cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:100]; 
    [serviceRequest setValue:@"text/xml" forHTTPHeaderField:@"Content-type"]; 
    [serviceRequest setHTTPMethod:@"POST"]; 
    [serviceRequest setHTTPBody:[xmlStr dataUsingEncoding:NSUTF8StringEncoding]]; 
    NSURLConnection *conn=[[[NSURLConnection alloc] initWithRequest:serviceRequest delegate:self startImmediately:YES] autorelease]; 
} 

所有上面的代碼我的代碼爲我工作正常，但現在我希望在此代碼中包含另一個功能其中包含發件人電子郵件地址，但此發件人電子郵件必須從設備中獲取，與在應用程序中使用MFMailComposeViewController時相同，然後自動獲取發件人來自Device.Email的發件人電子郵件地址。將受到感謝。

Answer 1

#import <AddressBook/AddressBook.h> 

NSString *emailAddr = @""; 
ABPerson *aPerson = [[ABAddressBook sharedAddressBook] me]; 
ABMultiValue *emails = [aPerson valueForProperty:kABEmailProperty]; 
if([emails count] > 0) 
    emailAddr = [emails valueAtIndex:0]; 

不要忘記添加AddressBook.framework。

現在，emailAddr包含發件人電子郵件，您可以附加到您的xml字符串或任何你想要的地方！

-(void)createXML 
{ 
    // Your code 
    NSString *emailStr=[NSString stringWithFormat:@"<email>%@</email>\n",emailAddr]; 
    xmlStr=[xmlStr stringByAppendingString:emailStr]; 
} 

快樂編碼！
