相机拍照，相册照片

首先，我们在头文件中添加需要用到的actionSheet控件，显示图片的UIImageView控件，并且加上所需要的协议

[objc] view plain copy

1. #import <UIKit/UIKit.h>  
2.   
3. @interface ImagePickerViewController : UIViewController<UIImagePickerControllerDelegate,UIActionSheetDelegate,UINavigationControllerDelegate>  
4.   
5. @property (strong, nonatomic) IBOutlet UIImageView *headImage;  
6.   
7. @property (strong, nonatomic) UIActionSheet *actionSheet;  
8.   
9. - (IBAction)clickPickImage:(id)sender;  
10. @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

1. //  
2.   
3. #import "ImagePickerViewController.h"  
4.   
5. @interface ImagePickerViewController ()

8.   
9. @implementation ImagePickerViewController

20.     [super didReceiveMemoryWarning];  
21.     // Dispose of any resources that can be recreated.

///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]];
    }
}
