我知道这已经被问了一些时间,但我找不到答案.
我有一个应用程序使用UIImagePickerController来拍照.问题是我只想要相机选项可用,我明白我需要隐藏标准控件：
cameraUI.showsCameraControls=NO;
并使用cameraOverlayView来提供我自己的控件.我已经看过苹果的PhotoPicker项目,我的初始问题是如何将Overlay对象放到我的故事板上？我在图书馆里找不到这样的对象.任何帮助感激不尽.
解决方法
这是代码：
toolBar=[[UIToolbar alloc] initWithFrame:CGRectMake(0,self.view.frame.size.height-54,self.view.frame.size.width,55)];
toolBar.barStyle = UIBarStyleBlackOpaque;
NSArray *items=[NSArray arrayWithObjects:
[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(cancelPicture)],[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:@selector(shootPicture)],nil];
[toolBar setItems:items];
// create the overlay view
overlayView = [[OverlayView alloc] initWithFrame:CGRectMake(0,self.view.frame.size.height-44)];
// important - it needs to be transparent so the camera preview shows through!
overlayView.opaque=NO;
overlayView.backgroundColor=[UIColor clearColor];
// parent view for our overlay
UIView *cameraView=[[UIView alloc] initWithFrame:self.view.bounds];
[cameraView addSubview:overlayView];
[cameraView addSubview:toolBar];
imagePickerController = [[UIImagePickerController alloc] init];
if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] == NO){
NSLog(@"Camera not available");
return;
}
imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
imagePickerController.delegate = self;
// hide the camera controls
imagePickerController.showsCameraControls=NO;
imagePickerController.wantsFullScreenLayout = YES;
[imagePickerController setCameraOverlayView:cameraView];
[self presentViewController:imagePickerController animated:YES completion:nil];
在你的头文件中声明这一点：
UIImagePickerController * imagePickerController; UIToolbar *toolBar; OverlayView *overlayView;
从ApplePhotoPicker添加此OverlayView.h和.m类.
使用自定义相机按钮拍摄照片的操作：
-(void) shootPicture {
[imagePickerController takePicture];
}
- (IBAction)cancelPicture {
[self dismissViewControllerAnimated:YES completion:nil];
}
输出将如下图所示(我在自定义叠加视图中添加了一个捕获按钮和取消按钮)：
快乐编码:)
