我想出了一个小技巧,它对我有用。我还是有点新,所以请随意优化,因为我找不到其他方法来做到这一点。
基本思想是在默认相机按钮上创建一个不可见按钮,该按钮执行调用 [uiimagepickercontroller takePicture] 的方法
这是我的示例代码
@implementation myViewController
{
UIImagePickerController *myImagePickerController;
UIButton * fakeCameraButton;
}
- (IBAction)showImagePicker:(id)sender{
// accessible camera validations implied
myImagePickerController = [[UIImagePickerController alloc]init];
myImagePickerController.sourceType=UIImagePickerControllerSourceTypeCamera;
myImagePickerController.showsCameraControls = YES;
myImagePickerController.delegate=self;
myImagePickerController.allowsEditing=YES;
CGFloat myViewHeight = 100; // you play around with the positions to get your desired frame size. This worked for me
UIView * myView = [[UIView alloc] initWithFrame:CGRectMake(0, myImagePickerController.view.frame.size.height - myViewheight, picker.view.frame.size.width, myViewheight)];
fakeCameraButton = [[UIButton alloc] initWithFrame:CGRectMake(myView.frame.size.width / 2 - 30, myView.frame.size.height/2-15, 60, 60)];// position it over the default camera button
[fakeCameraButton addTarget:self action:@selector(cameraButtonPressed) forControlEvents:UIControlEventTouchUpInside];
[fakeCameraButton setTitle:@"" forState:UIControlStateNormal];
[myView addSubview:fakeCameraButton];
myImagePickerController.cameraOverlayView = myView;
[self presentViewController:myImagePickerController animated:YES completion:nil];
}
-(void)cameraButtonPressed{
// Make sure you check if camera is ready before this method.
[myImagePickerController takePicture];
// you are in editing/preview mode here if allowsEditing = YES
// you can remove all your custom overlay views by
myImagePickerController.cameraOverlay = nil
}
就像我之前说的,只要确保你检查相机是否准备好。您可以在 stackoverflow 上找到有关如何操作的答案。
此代码可能很糟糕,因此欢迎编辑或替代解决方案。
