我的CvVideoCamera自动旋转,我不希望它.
This has been raised on the bugtracker,但一段时间没有活动.
解决方法
子类CvVideoCamera,并且只是删除旋转代码.我希望我的方向永远是肖像,所以这很简单：
MyCvVideoCamera.h
#import <opencv2/highgui/cap_ios.h> @interface MyCvVideoCamera : CvVideoCamera - (void)updateOrientation; - (void)layoutPreviewLayer; @property (nonatomic,retain) CALayer *customPreviewLayer; @end
MyCvVideoCamera.m
#import "MyCvVideoCamera.h"
@implementation MyCvVideoCamera
- (void)updateOrientation;
{
// nop
}
- (void)layoutPreviewLayer;
{
if (self.parentView != nil) {
CALayer* layer = self.customPreviewLayer;
CGRect bounds = self.customPreviewLayer.bounds;
layer.position = CGPointMake(self.parentView.frame.size.width/2.,self.parentView.frame.size.height/2.);
layer.bounds = bounds;
}
}
@end
