横向中的MFMailComposeViewController [英] MFMailComposeViewController in landscape

问题描述

我的应用程序处于风景模式，当我通过Present模型视图调用MFMailComposeViewController时，它进入了风景模式.我将设备旋转，而MFMailComposeViewController视图转到了肖像模式，我想限制这种旋转，它应该始终仅在风景模式中.有什么办法可以做到的.

My application is in landscape mod.When i call MFMailComposeViewController through Present model view, it comes in landscape mod.I rotate device and MFMailComposeViewController view goes to portrait mod i want to restrict this rotation it should always be in landscape mod only.Is there any way to do it..

推荐答案

子类化MFMailComposeViewController类，以便您可以覆盖它的shouldAutorotateToInterfaceOrientation来显示它，但是您喜欢:

Subclass the MFMailComposeViewController class, so that you can override its shouldAutorotateToInterfaceOrientation to display it however you like:

@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

指定新类代替MFMailComposeViewController:

Specify the new class in place of 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];
