Usage

Basic

Take photo

#import "IRCameraViewController.h"

@interface IRViewController : UIViewController <IRCameraDelegate>

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

- (IBAction)takePhotoTapped;

@end



@implementation IRViewController

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

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

#pragma mark - IRCameraDelegate 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 - IRCameraDelegate 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 "IRCameraViewController.h"

@interface IRViewController : UIViewController
<UINavigationControllerDelegate, UIImagePickerControllerDelegate>

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

- (IBAction)chooseExistingPhotoTapped;

@end



@implementation IRViewController

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

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

#pragma mark - UIImagePickerControllerDelegate

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

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

@end

Change colors

@implementation IRViewController

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

@end

    //...
    [IRCamera setOption:kIRCameraOptionHiddenToggleButton value:@YES];
    [IRCamera setOption:kIRCameraOptionHiddenAlbumButton value:@YES];
    [IRCamera setOption:kIRCameraOptionHiddenFilterButton value:@YES];
    [IRCamera setOption:kIRCameraOptionSaveImageToAlbum value:@YES];
    //...
}

- (IBAction)buttonTapped
{
    //...
    BOOL hiddenToggleButton = [[IRCamera getOption:kIRCameraOptionHiddenToggleButton] boolValue];
    BOOL hiddenAlbumButton = [[IRCamera getOption:kIRCameraOptionHiddenAlbumButton] boolValue];
    BOOL hiddenFilterButton = [[IRCamera getOption:kIRCameraOptionHiddenFilterButton] boolValue];
    BOOL saveToDevice = [[IRCamera getOption:kIRCameraOptionSaveImageToAlbum] boolValue];
    //...    
}

@end

Advanced settings

Custom image filters(You can see how GPUImage work in the demo project):

• Return YES by customizePhotoProcessingView in the IRCameraDelegate to disable the default filters

#pragma mark - IRCameraDelegate

- (BOOL)customizePhotoProcessingView {
    return YES;
}

• Deal with the image by your own way:

#import <GPUImage/GPUImage.h>

- (UIImage *)imageWithSketchFilter:(UIImage *)originImage {
    GPUImageFilter *imageFilter = [[GPUImageSketchFilter alloc] init];
    return [imageFilter imageByFilteringImage:originImage];
}
