Who uses it

Find out who uses TGCameraViewController and add your app to the list.

Adding to your project

CocoaPods is the recommended way to add TGCameraViewController to your project.

Add a pod entry for TGCameraViewController to your Podfile:

pod 'TGCameraViewController'

Install the pod by running:

pod install

Alternatively, you can download the latest code version directly and import the files to your project.

Privacy (iOS 10)

If you are building your app with iOS 10 or newer, you need to add two privacy keys to your app's Info.plist to allow the usage of the camera and photo library, or your app will crash.

Add the keys below to the <dict> tag of your Info.plist, replacing the strings with the description you want to provide when prompting the user:

	<key>NSPhotoLibraryUsageDescription</key>
	<string>Enable Photos access to import photos from your library.</string>
	<key>NSCameraUsageDescription</key>
	<string>Enable Camera to take photos.</string>

Usage

Here are some usage examples with Objective-C. You can find example projects for Objective-C and Swift 3 cloning the project. Refer to version 2.2.5 if you need a Swift 2.3 example.

Take photo

#import "TGCameraViewController.h"

@interface TGViewController : UIViewController <TGCameraDelegate>

@property (strong, nonatomic) IBOutlet UIImageView *photoView;

- (IBAction)takePhotoTapped;

@end



@implementation TGViewController

- (IBAction)takePhotoTapped
{
    TGCameraNavigationController *navigationController =
    [TGCameraNavigationController newWithCameraDelegate:self];

    [self presentViewController:navigationController animated:YES completion:nil];
}

#pragma mark - TGCameraDelegate optional

- (void)cameraWillTakePhoto
{
    NSLog(@"%s", __PRETTY_FUNCTION__);
}

- (void)cameraDidSavePhotoAtPath:(NSURL *)assetURL
{
    // When this method is implemented, an image will be saved on the user's device
    NSLog(@"%s album path: %@", __PRETTY_FUNCTION__, assetURL);
}

- (void)cameraDidSavePhotoWithError:(NSError *)error
{
    NSLog(@"%s error: %@", __PRETTY_FUNCTION__, error);
}

#pragma mark - TGCameraDelegate required

- (void)cameraDidCancel
{
    [self dismissViewControllerAnimated:YES completion:nil];
}

- (void)cameraDidTakePhoto:(UIImage *)image
{
    _photoView.image = image;
    [self dismissViewControllerAnimated:YES completion:nil];
}

- (void)cameraDidSelectAlbumPhoto:(UIImage *)image
{
    _photoView.image = image;
    [self dismissViewControllerAnimated:YES completion:nil];
}

@end

Choose photo

#import "TGCameraViewController.h"

@interface TGViewController : UIViewController
<UINavigationControllerDelegate, UIImagePickerControllerDelegate>

@property (strong, nonatomic) IBOutlet UIImageView *photoView;

- (IBAction)chooseExistingPhotoTapped;

@end



@implementation TGViewController

- (IBAction)chooseExistingPhotoTapped
{
    UIImagePickerController *pickerController =
    [TGAlbum imagePickerControllerWithDelegate:self];

    [self presentViewController:pickerController animated:YES completion:nil];
}

#pragma mark - UIImagePickerControllerDelegate

- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    _photoView.image = [TGAlbum imageWithMediaInfo:info];
    [self dismissViewControllerAnimated:YES completion:nil];
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
    [self dismissViewControllerAnimated:YES completion:nil];
}

@end

Change colors

@implementation TGViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    
    UIColor *tintColor = [UIColor greenColor];
    [TGCameraColor setTintColor:tintColor];

Requirements

TGCameraViewController works on iOS 8.0+ version and is compatible with ARC projects. It depends on the following Apple frameworks, which should already be included with most Xcode templates:

• AssetsLibrary.framework
• AVFoundation.framework
• CoreImage.framework
• Foundation.framework
• MobileCoreServices.framework
• UIKit.framework

You will need LLVM 3.0 or later in order to build TGCameraViewController.

To do

• Landscape mode support
• Zoom
• Image size as global parameter
• Fast animations
• Create a custom picker controller
• Zoom does not work with the camera roll pictures
