[ios]MFMessageComposeViewController 等 系统页面 禁旋转

 

查项目有需求 让系统弹出页面也不能旋转

实现思路

利用category覆写MFMessageComposeViewController 的

 

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;)

(方法,ios 6则是另外2个方法)

 

代码

.h

@interface MFMessageComposeViewController(Portrait)

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation;

 

@end

 

.m

@implementation MFMessageComposeViewController(Portrait)

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{

    return (interfaceOrientation == UIInterfaceOrientationPortrait);

}

 

@end
