MFMailComposeViewController在风景中

Question

我的应用程序是在横向模式.当我通过Present模型视图调用MFMailComposeViewController时,它来自横向mod.I旋转设备和MFMailComposeViewController视图转到纵向模式我想要限制此旋转它应该始终只在横向模式中.是否有任何这样做的方式..

Answer 1

对MFMailComposeViewController类进行子类化,以便您可以覆盖其shouldAutorotateToInterfaceOrientation以显示它,但是您喜欢:

@interface MailCompose : MFMailComposeViewController {
}
@end

@implementation MailCompose

// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}

@end

指定新类来代替MFMailComposeViewController:

MailCompose *controller = [[MailCompose alloc] init];
controller.mailComposeDelegate = self;
[controller setSubject:@"In app email..."];
[controller setMessageBody:@"...email body." isHTML:NO];
[self presentModalViewController:controller animated:YES];
[controller release];
