[fileManager createFileAtPath:fullPath contents:imageData attributes:nil]; //finally save the image 

NSLog(@"image saved"); 
} 

@end

這是我寫的以下代碼，但我不能保存images.i我只能夠理解一個圖像被稱爲NULL.png .please建議更改以保存我的圖書館中的所有圖片進行捆綁。試圖從照片庫保存圖像在ipad應用程序捆綁

感謝，克里斯蒂

錯誤請幫助 – Christina 2011-04-26 13:39:07

嗨克里斯蒂娜，你檢查的UIImage *圖像爲零或不？和imageData是否爲零？ – 2011-04-26 13:40:18

我認爲這是零，這是問題地獄，我很困惑，從圖像獲取圖像圖像，可以üPLZ告訴我， – Christina 2011-04-26 13:50:39

示例代碼

- (void) openPhotoLibrary { 
     NSLog(@"openPhotolibrary"); 

     if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) { 
      if (self.picker != nil) { 
       NSLog(@"releasing self.picker..."); 
       [self.picker release]; 
      } 
      self.picker = [[UIImagePickerController alloc] init]; 
      self.picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
      //self.picker.allowsImageEditing = YES; 
      [self.picker presentModalViewController:self.picker animated:YES]; 
      self.picker.delegate = self; 

      [[[CCDirector sharedDirector] openGLView] addSubview:self.picker.view]; 
     } 
    } 

    - (void)imagePickerControllerDidCancel:(UIImagePickerController *)currentPicker { 
     NSLog(@"imagePickerControllerDidCancel"); 

     // hide the self.picker if user cancels picking an image. 
     [currentPicker dismissModalViewControllerAnimated:YES]; 
     self.picker.view.hidden = YES; 
     [self.picker.view removeFromSuperview]; 
    } 

    - (void)imagePickerController:(UIImagePickerController *)currentPicker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo 
    { 
     [self saveImage:image withImageName:@"myPhoto"]; 

    } 

//saving an image 

- (void)saveImage:(UIImage*)image withImageName:(NSString*)imageName { 

NSData *imageData = UIImagePNGRepresentation(image); //convert image into .png format. 

NSFileManager *fileManager = [NSFileManager defaultManager];//create instance of NSFileManager 

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //create an array and store result of our search for the documents directory in it 

NSString *documentsDirectory = [paths objectAtIndex:0]; //create NSString object, that holds our exact path to the documents directory 

NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.png", imageName]]; //add our image to the path 

[fileManager createFileAtPath:fullPath contents:imageData attributes:nil]; //finally save the path (image) 

NSLog(@"image saved"); 

}

但它的照片不適合視頻 – Shima 2011-07-20 11:38:16

此代碼的工作，我嘗試它可能是它可以幫助你

-(IBAction)PhotoLibraryButtonClicked:(id)sender{ 
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]){ 


    imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    [self presentModalViewController:imagePicker animated:YES]; 

} 
else{ 

    [self displaysorceError]; 

    } 

} 


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

//[self.popoverrcontroller dismissPopoverAnimated:true]; 
//[popoverrcontroller release]; 

NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; 
[self dismissModalViewControllerAnimated:YES]; 

if([mediaType isEqualToString:(NSString *)kUTTypeImage]){ 

    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; 
// UIImage *rote = [image rotateInDegrees:219.0f]; 

    img.image = image; 
    if(newMedia) 
     UIImageWriteToSavedPhotosAlbum(image, nil,nil, nil); 
}else if([mediaType isEqualToString:(NSString *)kUTTypeImage]){ 

    //not available vidio 
} 
} 


-(IBAction)saveImageIn:(id)sender{ 

NSData *imageData = UIImagePNGRepresentation(img.image); 

NSFileManager *fileMan = [NSFileManager defaultManager]; 
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *fullPathToFile = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@" %d.png",img.image]]; 

[fileMan createFileAtPath:fullPathToFile contents:imageData attributes:nil]; 



UIAlertView *alt = [[UIAlertView alloc] 
        initWithTitle:@"Thank You" 
        message:@"Image Save In Directory" 
        delegate:nil cancelButtonTitle:@"OK" 
        otherButtonTitles:nil]; 
[alt show]; 
[alt release]; 
}

謝謝.. :)啃老族

**將photolibrary中的uiimage保存至Bundle **

。（空隙）imagePickerController：（的UIImagePickerController *）選擇器didFinishPickingImage：（的UIImage *）圖像editingInfo：（的NSDictionary *）editingInfo {

[self dismissModalViewControllerAnimated:YES]; 


    imgview =[[UIImageView alloc]initWithFrame:CGRectMake(30, 30, 100, 100)]; 

    imgview.image =image; 
    [self.view addSubview:imgview]; 
    [imgview setUserInteractionEnabled:YES];

}

（IBAction爲）saveimg：（ID）發送方{

NSData *imageData = UIImageJPEGRepresentation(imgview.image,1.0); 

NSFileManager *fileMan = [NSFileManager defaultManager]; 
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 
NSString *fullPathToFile = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"deepu22%d.jpg",imgview.image]]; 

[fileMan createFileAtPath:fullPathToFile contents:imageData attributes:nil]; 



UIAlertView *alt = [[UIAlertView alloc] 
        initWithTitle:@"Thank You" 
        message:@"Image Save In Directory" 
        delegate:nil cancelButtonTitle:@"OK" 
        otherButtonTitles:nil]; 
[alt show];

}

。（IBAction爲）PIC * KERS：（ID）發送{

picker =[[UIImagePickerController alloc]init]; 

    picker.delegate=self; 
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    [self presentModalViewController:picker animated:YES];

} *
