[objc] view plain copy #import <UIKit/UIKit.h> @interface ImagePickerViewController : UIViewController<UIImagePickerControllerDelegate,UIActionSheetDelegate,UINavigationControllerDelegate> @property (strong, nonatomic) IBOutlet UIImageView *headImage; @property (strong, nonatomic) UIActionSheet *actionSheet; - (IBAction)clickPickImage:(id)sender; @end
通过点击我设置在界面中的按钮来呼出actionSheet控件，来选择相应的操作拍照或是在相册中选择相片，代码如下：
[objc] view plain copy // #import "ImagePickerViewController.h" @interface ImagePickerViewController () @end @implementation ImagePickerViewController @synthesize actionSheet = _actionSheet; - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view from its nib. } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } /** @ 调用ActionSheet */ - (void)callActionSheetFunc{ if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){ self.actionSheet = [[UIActionSheet alloc] initWithTitle:@"选择图像" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:nil otherButtonTitles:@"拍照", @"从相册选择", nil nil]; }else{ self.actionSheet = [[UIActionSheet alloc] initWithTitle:@"选择图像" delegate:self cancelButtonTitle:@"取消"destructiveButtonTitle:nil otherButtonTitles:@"从相册选择", nil nil]; } self.actionSheet.tag = 1000; [self.actionSheet showInView:self.view]; } // Called when a button is clicked. The view will be automatically dismissed after this call returns - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{ if (actionSheet.tag == 1000) { NSUInteger sourceType = UIImagePickerControllerSourceTypePhotoLibrary; // 判断是否支持相机 if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) { switch (buttonIndex) { case 0: //来源:相机 sourceType = UIImagePickerControllerSourceTypeCamera; break; case 1: //来源:相册 sourceType = UIImagePickerControllerSourceTypePhotoLibrary; break; case 2: return; } } else { if (buttonIndex == 2) { return; } else { sourceType = UIImagePickerControllerSourceTypePhotoLibrary; } } // 跳转到相机或相册页面 UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init]; imagePickerController.delegate = self; imagePickerController.allowsEditing = YES; imagePickerController.sourceType = sourceType; [self presentViewController:imagePickerController animated:YES completion:^{ }]; } } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { [picker dismissViewControllerAnimated:YES completion:^{ }]; UIImage *image = [info objectForKey:UIImagePickerControllerEditedImage]; self.headImage.image = image; } /* #pragma mark - Navigation // In a storyboard-based application, you will often want to do a little preparation before navigation - (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { // Get the new view controller using [segue destinationViewController]. // Pass the selected object to the new view controller. } */ - (IBAction)clickPickImage:(id)sender { [self callActionSheetFunc]; } @end///注意点
1.
typedef NS_ENUM(NSInteger, UIImagePickerControllerSourceType) {
UIImagePickerControllerSourceTypePhotoLibrary,
UIImagePickerControllerSourceTypeCamera,
UIImagePickerControllerSourceTypeSavedPhotosAlbum
};
分别表示：图片列表，摄像头，相机相册 2.plist文件配置 3.打开相册，导航条是白色的，看不到取消的itme；- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated { if ([navigationController isKindOfClass:[UIImagePickerController class]]) { [viewController.navigationController.navigationBar setTintColor:[UIColor blackColor]]; } }
