DBCamera is a simple custom camera with AVFoundation.

Getting Started

Installation

The recommended approach for installating DBCamera is via the CocoaPods package manager, as it provides flexible dependency management and dead simple installation.

Podfile

platform :ios, '6.0'
pod 'DBCamera', '~> 2.4'

via Apache Cordova

DBCamera is available for use as an apache cordova plugin for ios. Visit Cordova-DBCamera for more.

Example

If you use the example project, run pod install to install GPUImage dependency

Integration

DBCamera has a simple integration:

#import "DBCameraViewController.h"
#import "DBCameraContainerViewController.h"
//Add DBCameraViewControllerDelegate protocol
@interface RootViewController () <DBCameraViewControllerDelegate>
//Present DBCameraViewController with different behaviours

- (void) openCamera
{
    DBCameraContainerViewController *cameraContainer = [[DBCameraContainerViewController alloc] initWithDelegate:self];
    [cameraContainer setFullScreenMode];

    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:cameraContainer];
    [nav setNavigationBarHidden:YES];
    [self presentViewController:nav animated:YES completion:nil];
}

- (void) openCameraWithoutSegue
{
    DBCameraViewController *cameraController = [DBCameraViewController initWithDelegate:self];
    [cameraController setUseCameraSegue:NO];

    DBCameraContainerViewController *container = [[DBCameraContainerViewController alloc] initWithDelegate:self];
    [container setCameraViewController:cameraController];
    [container setFullScreenMode];

    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:container];
    [nav setNavigationBarHidden:YES];
    [self presentViewController:nav animated:YES completion:nil];
}

- (void) openCameraWithoutContainer
{
    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:[DBCameraViewController initWithDelegate:self]];
    [nav setNavigationBarHidden:YES];
    [self presentViewController:nav animated:YES completion:nil];
}
//Use your captured image
#pragma mark - DBCameraViewControllerDelegate

- (void) camera:(id)cameraViewController didFinishWithImage:(UIImage *)image withMetadata:(NSDictionary *)metadata
{
    DetailViewController *detail = [[DetailViewController alloc] init];
    [detail setDetailImage:image];
    [self.navigationController pushViewController:detail animated:NO];
    [cameraViewController restoreFullScreenMode];
    [self.presentedViewController dismissViewControllerAnimated:YES completion:nil];
}

- (void) dismissCamera:(id)cameraViewController{
    [self dismissViewControllerAnimated:YES completion:nil];
    [cameraViewController restoreFullScreenMode];
}

By default, DBCameraViewController has another controller to display the image preview.
When you create DBCameraViewController instance, you can set useCameraSegue: NO, to avoid it.

- (void) openCameraWithoutSegue
{
    DBCameraContainerViewController *container = [[DBCameraContainerViewController alloc] initWithDelegate:self];
    DBCameraViewController *cameraController = [DBCameraViewController initWithDelegate:self];
    [cameraController setUseCameraSegue:NO];
    [container setCameraViewController:cameraController];
    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:container];
    [nav setNavigationBarHidden:YES];
    [container setFullScreenMode];
    [self presentViewController:nav animated:YES completion:nil];
}

If you want, you can force the crop option within segue view controller. Set setForceQuadCrop: YES

- (void) openCameraWithForceQuad
{
    DBCameraViewController *cameraController = [DBCameraViewController initWithDelegate:self];
    [cameraController setForceQuadCrop:YES];

    DBCameraContainerViewController *container = [[DBCameraContainerViewController alloc] initWithDelegate:self];
    [container setCameraViewController:cameraController];
    [container setFullScreenMode];

    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:container];
    [nav setNavigationBarHidden:YES];
    [self presentViewController:nav animated:YES completion:nil];
}

You can use the Library picker as separated view controller.

- (void) openLibrary
{
    DBCameraLibraryViewController *vc = [[DBCameraLibraryViewController alloc] init];
    [vc setDelegate:self]; //DBCameraLibraryViewController must have a DBCameraViewControllerDelegate object
//    [vc setForceQuadCrop:YES]; //Optional
//    [vc setUseCameraSegue:YES]; //Optional
    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:vc];
    [nav setNavigationBarHidden:YES];
    [self presentViewController:nav animated:YES completion:nil];
}

Customizing the camera

Basic

For simple customizations, you can customize the built-in camera view by sending a cameraSettingsBlock to the view controller.

#import "DBCameraView.h"
- (void)openCameraWithSettings:(CDVInvokedUrlCommand*)command
{
    DBCameraContainerViewController *cameraContainer = [[DBCameraContainerViewController alloc] initWithDelegate:self cameraSettingsBlock:^(DBCameraView *cameraView, DBCameraContainerViewController *container) {
        [cameraView.photoLibraryButton setHidden:YES]; //Hide Library button

        //Override the camera grid
        DBCameraGridView *cameraGridView = [[DBCameraGridView alloc] initWithFrame:cameraView.previewLayer.frame];
        [cameraGridView setNumberOfColumns:4];
        [cameraGridView setNumberOfRows:4];
        [cameraGridView setAlpha:0];
        [container.cameraViewController setCameraGridView:cameraGridView];
    }];

    //Set the Tint Color and the Selected Color
    [cameraContainer setTintColor:[UIColor redColor]];
    [cameraContainer setSelectedTintColor:[UIColor yellowColor]];
}

Customize the Segue View controller

For a simple customization, you can use the block cameraSegueConfigureBlock

#import "DBCameraSegueViewController.h"
[cameraController setCameraSegueConfigureBlock:^( DBCameraSegueViewController *segue ) {
  segue.cropMode = YES;
  segue.cropRect = (CGRect){ 0, 0, 200, 400 };
}];

Advanced

You can also create a custom interface, using a subclass of DBCameraView

#import "DBCameraView.h"

@interface CustomCamera : DBCameraView
- (void) buildInterface;
@end
#import "CustomCamera.h"

@interface CustomCamera ()
@property (nonatomic, strong) UIButton *closeButton;
@property (nonatomic, strong) CALayer *focusBox, *exposeBox;
@end

@implementation CustomCamera

- (void) buildInterface
{
    [self addSubview:self.closeButton];

    [self.previewLayer addSublayer:self.focusBox];
    [self.previewLayer addSublayer:self.exposeBox];

    [self createGesture];
}

- (UIButton *) closeButton
{
    if ( !_closeButton ) {
        _closeButton = [UIButton buttonWithType:UIButtonTypeCustom];
        [_closeButton setBackgroundColor:[UIColor redColor]];
        [_closeButton setImage:[UIImage imageNamed:@"close"] forState:UIControlStateNormal];
        [_closeButton setFrame:(CGRect){ CGRectGetMidX(self.bounds) - 15, 17.5f, 30, 30 }];
        [_closeButton addTarget:self action:@selector(close) forControlEvents:UIControlEventTouchUpInside];
    }

    return _closeButton;
}

- (void) close
{
    if ( [self.delegate respondsToSelector:@selector(closeCamera)] )
        [self.delegate closeCamera];
}

#pragma mark - Focus / Expose Box

- (CALayer *) focusBox
{
    if ( !_focusBox ) {
        _focusBox = [[CALayer alloc] init];
        [_focusBox setCornerRadius:45.0f];
        [_focusBox setBounds:CGRectMake(0.0f, 0.0f, 90, 90)];
        [_focusBox setBorderWidth:5.f];
        [_focusBox setBorderColor:[[UIColor whiteColor] CGColor]];
        [_focusBox setOpacity:0];
    }

    return _focusBox;
}

- (CALayer *) exposeBox
{
    if ( !_exposeBox ) {
        _exposeBox = [[CALayer alloc] init];
        [_exposeBox setCornerRadius:55.0f];
        [_exposeBox setBounds:CGRectMake(0.0f, 0.0f, 110, 110)];
        [_exposeBox setBorderWidth:5.f];
        [_exposeBox setBorderColor:[[UIColor redColor] CGColor]];
        [_exposeBox setOpacity:0];
    }

    return _exposeBox;
}

- (void) drawFocusBoxAtPointOfInterest:(CGPoint)point andRemove:(BOOL)remove
{
    [super draw:_focusBox atPointOfInterest:point andRemove:remove];
}

- (void) drawExposeBoxAtPointOfInterest:(CGPoint)point andRemove:(BOOL)remove
{
    [super draw:_exposeBox atPointOfInterest:point andRemove:remove];
}

@end
//Present DBCameraViewController with a custom view.
@interface RootViewController () <DBCameraViewControllerDelegate>

- (void) openCustomCamera
{
    CustomCamera *camera = [CustomCamera initWithFrame:[[UIScreen mainScreen] bounds]];
    [camera buildInterface];

    UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:[[DBCameraViewController alloc] initWithDelegate:self
                                                                                                                                   cameraView:camera]];
    [nav setNavigationBarHidden:YES];
    [self presentViewController:nav animated:YES completion:nil];
}
