胡舒立背后的大人物,杨岳最近没有露面,课后反思
1.初始MessageUI.framework
在MessageUI.framework中主要有两个控制器类分别用于发送短信 （MFMessageComposeViewController）和邮件（MFMailComposeViewController）,它们均继承于UINavigationController。
2.发送彩信
a、创建对象
@property(nonatomic, weak)IBOutlet UITextField *consignee;//收件人 @property(nonatomic, weak)IBOutlet UITextField *mainBody;//正文 @property(nonatomic, weak)IBOutlet UITextField *subject;//主题 @property(nonatomic, weak)IBOutlet UITextField *attachments;//附件b、发彩信
我要评论- (IBAction)sendMessageClick:(UIButton *)sender{
(1)判断是否可以发送文本:
if ([MFMessageComposeViewController canSendText]) {
MFMessageComposeViewController *messageControlller = [[MFMessageComposeViewController alloc]init];
//收件人 :
messageControlller.recipients = [self.consignee.text componentsSeparatedByString:@","];
//信息正文：
messageControlller.body = self.mainBody.text;
//设置代理(<**MFMessageComposeViewControllerDelegate**>)
messageControlller.**messageComposeDelegate** = self;
(2)判断运营商是否支持主题
if ([MFMessageComposeViewController canSendSubject]) {
messageControlller.subject = self.subject.text;
}else{
NSLog(@"不支持主题");
}
(3)判断运营商是否支持附件
if ([MFMessageComposeViewController canSendAttachments]) {
// 发送纯文本形式
NSArray *attachments = [_attachments.text componentsSeparatedByString:@","];
if (attachments.count > 0) {
[attachments enumerateObjectsUsingBlock:^(id _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
NSString *path = [[NSBundle mainBundle]pathForResource:obj ofType:nil];
NSURL *url = [NSURL fileURLWithPath:path];
[messageControlller addAttachmentURL:url
withAlternateFilename:obj];
}];
}
// 发送照片类型
NSString *path = [[NSBundle mainBundle]pathForResource:@"photo.jpg" ofType:nil];
NSURL *url = [NSURL URLWithString:path];
NSData *data = [NSData dataWithContentsOfURL:url];
[messageControlller addAttachmentData:data typeIdentifier:@"public.image" filename:@"photo.jpg"];
}else{
NSLog(@"不支持附件");
}
[self presentViewController:messageControlller animated:YES completion:nil];
}
}
3、协议方法
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{
switch (result) {
case MessageComposeResultCancelled:
NSLog(@"取消发送");
break;
case MessageComposeResultSent:
NSLog(@"发送成功");
break;
case MessageComposeResultFailed:
NSLog(@"发送失败");
break;
default:
break;
}
[self dismissViewControllerAnimated:YES completion:nil];
}
