我有以下代码,当调用操作表上的按钮时调用该代码。但是当我按下取消键,然后删除草稿时,它只是 feezes 而不是关闭。我在我的应用程序的其他地方使用了相同的代码,它是从一个 tableview 单元格的选择中调用的,它在那里工作。知道为什么它在这里不起作用吗?
当它卡住时,控制台中也没有错误消息。
if([MFMailComposeViewController canSendMail])
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:@"Dr. Chrono Support"];
NSDictionary* infoDict = [[NSBundle mainBundle] infoDictionary];
NSString* versionNum = [infoDict objectForKey:@"CFBundleVersion"];
NSString *appName = [infoDict objectForKey:@"CFBundleDisplayName"];
NSString *text = [NSString stringWithFormat:@"%@ %@",appName,versionNum];
// Set up recipients
NSArray *toRecipients = [NSArray arrayWithObject:@"contact@drchrono.com"];
//NSArray *ccRecipients = [NSArray arrayWithObjects:@"second@example.com", @"third@example.com", nil];
//NSArray *bccRecipients = [NSArray arrayWithObject:@"fourth@example.com"];
[picker setToRecipients:toRecipients];
//[picker setCcRecipients:ccRecipients];
//[picker setBccRecipients:bccRecipients];
// Attach an image to the email
//NSString *path = [[NSBundle mainBundle] pathForResource:@"rainy" ofType:@"png"];
//NSData *myData = [NSData dataWithContentsOfFile:path];
//[picker addAttachmentData:myData mimeType:@"image/png" fileName:@"rainy"];
// Fill out the email body text
NSString *emailBody = text;
[picker setMessageBody:emailBody isHTML:NO];
[self presentModalViewController:picker animated:YES];
[picker release];
}
最佳答案
您需要实现委托(delegate)方法:
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
然后在这个委托(delegate)方法中添加:
[self dismissModalViewControllerAnimated:YES];
它应该工作得很好。
您不必查找结果(仅当您想要显示“谢谢”警报或其他内容时,例如,如果用户确实点击了“发送”)
