UIImagePickerController

1:让 UIImagePickerController 显示后 的状态栏始终保持某一种风格.

[csharp]  view plain copy

1. -(void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{  
2.     [[UIApplication  sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque];  
3. }  
4. -(void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{  
5.     [[UIApplication  sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque];  
6. }  

2:修改 UIImagePickerController 顶部导航栏的颜色风格

[html]  view plain copy

1. [[imagePickerController navigationBar] setTintColor:[UIColor colorWithRed:78.0/255.0 green:148.0/255.0 blue:201.0/255.0 alpha:1]];  

此方式同时适用于:短信,邮件等系统界面

3:是否显示照相机标准的控件库

[csharp]  view plain copy

1. imagePickerController.showsCameraControls = NO;  

4:将图片保存至系统照片库

[csharp]  view plain copy

1. UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);  

成功失败后的回调:

[csharp]  view plain copy

1. - (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo  
2. {  
3.     myImageView.image = image;  
4.     NSLog(@"%@",error);  
5. }  

5:将视频保存至系统照片库

[csharp]  view plain copy

1. NSString* path = [[info objectForKey:UIImagePickerControllerMediaURL] path];  
2. // 保存视频  
3. UISaveVideoAtPathToSavedPhotosAlbum(path, self, @selector(video:didFinishSavingWithError:contextInfo:), nil);   

成功失败后的回调:

[csharp]  view plain copy

1. - (void)video: (NSString *)videoPath didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo  
2. {  
3.     NSLog(@"%@",videoPath);  
4.     NSLog(@"%@",error);  
5. }  

[csharp]  view plain copy

1. //首先判断设备是否支持拍照功能  
2.     if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]) {  
3.         if (imagePickerController == nil) {  
4.               
5.               
6.             imagePickerController=[[UIImagePickerController alloc] init];  
7.             //只开启拍照  
8.             imagePickerController.sourceType=UIImagePickerControllerSourceTypeCamera;  
9.               
10.               
11.             //拍照 摄影 同时开启  
12.             //imagePickerController.mediaTypes =  [UIImagePickerController availableMediaTypesForSourceType:UIImagePickerControllerSourceTypeCamera];  
13.             //只开启 摄影  
14.             //imagePickerController.mediaTypes = [NSArray arrayWithObject:(NSString *)kUTTypeMovie];  
15.               
16.               
17.               
18.             imagePickerController.videoQuality = UIImagePickerControllerQualityTypeHigh;//视频质量:最好的          
19.             imagePickerController.cameraDevice =  UIImagePickerControllerCameraDeviceFront;  //默认启用前置摄像头  
20.             imagePickerController.delegate = self;  
21.             imagePickerController.modalTransitionStyle=UIModalTransitionStyleCrossDissolve;  
22.             imagePickerController.showsCameraControls = YES;//是否显示照相机标准的控件库  
23.             [imagePickerController setAllowsEditing:NO];//是否加入照相后预览时的编辑功能  
24.   
25.             //为相机添加自定义拍摄时的视图  
26.             //imagePickerController.cameraOverlayView = imagePreviewViewController.view;  
27.               
28.               
29.             CGRect rect = [[UIScreen mainScreen] bounds];  
30.             rect.origin.y = rect.origin.y +50;  
31.             rect.size.height = rect.size.height -130;  
32.             UIButton *btn =[UIButton buttonWithType:UIButtonTypeCustom];    
33.             [btn setFrame:rect];  
34.             //[btn setTitle:@"试试" forState:UIButtonTypeRoundedRect];  
35.             [btn addTarget:self action:@selector(SaveCamera) forControlEvents:UIControlEventTouchUpInside];  
36.             [imagePickerController.view addSubview:btn];  
37.               
38.         }  
39.           
40.         [self presentModalViewController:imagePickerController animated:YES];  
41.     }
