UIImagePickerController在相机翻转时冻结 [英] UIImagePickerController Freezes when camera flips

问题描述

当按下从前向后翻转相机的按钮时，我的UIImagePickerController冻结并且相机关闭.这就是我从方法中初始化项目中的图像选择器控制器对象(其余代码被省略)的方式，因为它与UIimagepickercontroller对象无关.

My UIImagePickerController freezes and the camera closes when the button to flip the camera from front to back is pressed. This is how I initialize the image picker controller object within the project (the rest of the code was ommitted) from the methods as it is irrelevant to the UIimagepickercontroller object.

//In my .h file 
UIImagePickerController * imgPicker;

//in my .m file
-(void)viewDidLoad {

imgPicker = [[UIImagePickerController alloc] init];
imgPicker.delegate = self;
imgPicker.allowsEditing = YES;

}

-(void) takePicture {

imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:imgPicker animated:YES completion:NULL];

}

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

masterImage.image = [info objectForKey:UIImagePickerControllerEditedImage];

if(masterImage.image == nil) {

    masterImage.image = [info objectForKey:UIImagePickerControllerEditedImage];

}

[self dismissModalViewControllerAnimated:YES];

}

-(void) imagePickerControllerDidCancel:(UIImagePickerController *)picker{

[self dismissModalViewControllerAnimated:YES];

}

-(void) releaseOutlets {

[imgPicker release];

}

推荐答案

就规则而言，更改代码.代替:

Just for rule, change your code. Instead of:

UIImagePickerController * imgPicker;

写入.h文件:

@property (nonatomic, strong) UIImagePickerController * imgPicker;

而不是将其合成到您的.m文件中:

than synthesize it in your .m file:

imgPicker = _imgPicker;

接下来，每次对该属性的调用都将用self进行调用.

and next every call to this property call with self.
