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];
}
