使用openURL发送邮件的问题

我正面临使用openURL打开邮件客户端的问题.这是代码.

NSString *subject = @"Demo Subject";
NSString *body = @"<html><head>Header</head><body><a href=\"http://example.com\">Here is the demo link</a></body></html>";
NSString *urlString = [NSString stringWithFormat:@"mailto:?&subject=%@&body=%@",subject,body];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlString]];

我想,是否需要使用特殊字符进行任何编码,这些编码确实存在,但示例文本中未显示.

谢谢

NSString *htmlBody = @"you probably want something HTML-y here";

// First escape the body using a CF call
NSString *escapedBody = [(NSString*)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,  (CFStringRef)htmlBody, NULL,  CFSTR("?=&+"), kCFStringEncodingUTF8) autorelease];

// Then escape the prefix using the NSString method
NSString *mailtoPrefix = [@"mailto:?subject=Some Subject&body=" stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

// Finally, combine to create the fully escaped URL string
NSString *mailtoStr = [mailtoPrefix stringByAppendingString:escapedBody];

// And let the application open the merged URL
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailtoStr]];
