问题UIImagePickerControllerDelegate，didFinishPickingMediaWithInfo没有调用

嘿家伙，我知道它已经被更频繁地询问，但他们的问题的答案似乎并不适用于此。问题UIImagePickerControllerDelegate，didFinishPickingMediaWithInfo没有调用

我didFinishPickingMediaWithInfo方法不会被调用:(

这里是我的代码：

的.H文件：

#import <UIKit/UIKit.h> 


@interface DevicePictureController : UIViewController <UINavigationControllerDelegate, UIImagePickerControllerDelegate> { 

    UIImageView *photo; 
    UIButton *selectPhoto; 
    UIButton *takePhoto; 
    NSMutableDictionary *listLocations; 
    NSMutableDictionary *listDevices; 
    UIImagePickerController *picker; 
} 

@property (nonatomic, retain) IBOutlet UIImageView *photo; 
@property (nonatomic, retain) IBOutlet UIButton *selectPhoto; 
@property (nonatomic, retain) IBOutlet UIButton *takePhoto; 
@property (nonatomic, retain) UIImagePickerController *picker; 

-(IBAction)selectPicture:(id)sender; 
@end

的的.m文件：＃进口 “ DevicePictureController.h“

@implementation DevicePictureController 
@synthesize photo, selectPhoto, takePhoto, picker; 

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    listLocations = [[NSMutableDictionary alloc] init]; 
    listDevices = [[NSMutableDictionary alloc] init]; 
    picker = [[UIImagePickerController alloc] init]; 
} 

-(IBAction)selectPicture:(id)sender { 

    picker.delegate = self; 
    picker.allowsEditing = YES; 

    if ((UIButton *)sender == selectPhoto) { 

     picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    } 
    else { 
     picker.sourceType = UIImagePickerControllerSourceTypeCamera; 
    } 

    [self presentModalViewController:picker animated:YES]; 
} 

-(void)imagePickController:(UIImagePickerController *)picked didFinishPickingMediaWithInfo:(NSDictionary *)info { 
    [picked dismissModalViewControllerAnimated:YES]; 
    NSLog(@"Geselecteerd: %@", [info objectForKey:UIImagePickerControllerEditedImage]); 
    //photo = [[UIImageView alloc] init]; 
    [photo setImage:[info objectForKey:UIImagePickerControllerEditedImage]]; 
} 

@end

所以，我的相册或我的相机被正确加载/激活，但是当我点击“使用”或照片时，在视图关闭后，我只能看到2个按钮和一个模糊的UIImageView。 'photo'连接到UIImageView，'selectPhoto'和'takePhoto'连接到它们的按钮，'selectPicture'连接到两个按钮'Touch Up Inside-action'。有人可以帮我吗？

您在删除方法中有错字。

应该

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

，但你必须

- (void)imagePickController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info

你打了我约50秒。所以避免重复的答案和投票你的答案 – visakh7 2011-04-07 12:27:16

- (void)viewDidLoad 
{ 
[super viewDidLoad]; 
listLocations = [[NSMutableDictionary alloc] init]; 
listDevices = [[NSMutableDictionary alloc] init]; 
picker = [[UIImagePickerController alloc] init]; 
picker.delegate = self; 
}

只是用这个替换你的viewDidLoad。设置picker.delegate = self; 所以它会调用它的委托方法didFinishPickingMediaWithInfo调用 – 2011-04-07 12:22:42
