OS4.0新加入了MFMessageComposeViewController和MFMessageComposeViewControllerDelegate,提供了发送短信的接口,可以像发送邮件那样不用跳出程序来发送短信. 介绍可参阅Message UI
Framework Reference
一些笔记:
MFMessageComposeViewController - 提供了操作界面
- 使用前必须检查canSendText方法,若返回NO则不应将这个controller展现出来,而应该提示用户不支持发送短信功能.
- 界面不能自行定制
- 要发送的短信的内容(body)和收件人(recipients)在展现这个controller前需初始化好,展现了之后短信内容不能通过程序来进行修改.不过用户仍然可以手工修改短信内容和选择收件人
- 用户点了发送或者取消,或者发送失败时,MFMessageComposeViewControllerDelegate 的– messageComposeViewController:didFinishWithResult:方法都能得到通知,在这里进行相应的处理
若在iOS3.0上运行的话,会提示dyld: Symbol not found: _OBJC_CLASS_$_MFMessageComposeViewController .解决方案:
- MessageUI.framework的引入类型应选择weak(在target -> Get Info -> General -> Linked Libraries -> MessageUI.framework -> Type 里修改)
- 不要在.h文件里直接import MessageUI/MFMessageComposeViewController.h,改为import <MessageUI/MessageUI.h>
代码:
- #pragma mark -
- #pragma mark SMS
-
- -(IBAction)showSMSPicker:(id)sender {
- // The MFMessageComposeViewController class is only available in iPhone OS 4.0 or later.
- // So, we must verify the existence of the above class and log an error message for devices
- // running earlier versions of the iPhone OS. Set feedbackMsg if device doesn't support
- // MFMessageComposeViewController API.
- Class messageClass = (NSClassFromString(@"MFMessageComposeViewController"));
-
- if (messageClass != nil) {
- // Check whether the current device is configured for sending SMS messages
- if ([messageClass canSendText]) {
- [self displaySMSComposerSheet];
- }
- else {
- [UIAlertView quickAlertWithTitle:@"设备没有短信功能" messageTitle:nil dismissTitle:@"关闭"];
- }
- }
- else {
- [UIAlertView quickAlertWithTitle:@"iOS版本过低,iOS4.0以上才支持程序内发送短信" messageTitle:nil dismissTitle:@"关闭"];
- }
- }
-
- -(void)displaySMSComposerSheet
- {
- MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
- picker.messageComposeDelegate = self;
-
- NSMutableString* absUrl = [[NSMutableString alloc] initWithString:web.request.URL.absoluteString];
- [absUrl replaceOccurrencesOfString:@"http://i.aizheke.com" withString:@"http://m.aizheke.com" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [absUrl length])];
-
- picker.body=[NSString stringWithFormat:@"我在爱折客上看到：%@ 可能对你有用，推荐给你！link：%@"
- ,[web stringByEvaluatingJavaScriptFromString:@"document.title"]
- ,absUrl];
- [absUrl release];
- [self presentModalViewController:picker animated:YES];
- [picker release];
- }
-
- - (void)messageComposeViewController:(MFMessageComposeViewController *)controller
- didFinishWithResult:(MessageComposeResult)result {
-
- switch (result)
- {
- case MessageComposeResultCancelled:
- LOG_EXPR(@"Result: SMS sending canceled");
- break;
- case MessageComposeResultSent:
- LOG_EXPR(@"Result: SMS sent");
- break;
- case MessageComposeResultFailed:
- [UIAlertView quickAlertWithTitle:@"短信发送失败" messageTitle:nil dismissTitle:@"关闭"];
- break;
- default:
- LOG_EXPR(@"Result: SMS not sent");
- break;
- }
- [self dismissModalViewControllerAnimated:YES];
- }
