畫廊將圖像保存到iPhone

Question

嗨，抱歉，我是菜鳥，但我正在學習。 我的應用程序中有Fgallery，但現在我想將條形按鈕連接到動作以將圖像保存到手機。 我需要一些代碼來提供當前圖像（在大圖像視圖中），希望有人可以幫助我解決這個問題。 這就是我所擁有的：

- (void)handleEditCaptionButtonTouch:(id)sender {
// here we could implement some code to change the caption for a stored image
[networkGallery saveImageAtIndex:[networkGallery currentIndex]];

}

這里有一個硬編碼的圖像，但是我需要當前圖像：

- (void)saveImageAtIndex:(NSUInteger)index
{

UIImage *image = [UIImage imageNamed:@"background.png"];
if(image != nil){
    UIImageWriteToSavedPhotosAlbum(image, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
}   
return; 

}


//saveImage method
-(void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo{
[BT_debugger showIt:self:[NSString stringWithFormat:@"finished saving image: %@", @""]];
NSString *message;  
NSString *title;  
if (!error) {  
    title = NSLocalizedString(@"SaveSuccessTitle", @"");  
    message = NSLocalizedString(@"SaveSuccessMessage", @"");  
} else {  
    title = NSLocalizedString(@"SaveFailedTitle", @"");  
    message = [error description];  
}  
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title  
                                                message:message  
                                               delegate:nil  
                                      cancelButtonTitle:NSLocalizedString(@"ButtonOK", @"")  
                                      otherButtonTitles:nil];  
[alert show];  
[alert release]; 
}

任何幫助將不勝感激。

在此先感謝DK

Answer 1

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
 img.image = [info valueForKey:@"UIImagePickerControllerOriginalImage"];

 [self dismissModalViewControllerAnimated:YES];
}

Answer 2

如果其他人正在尋找答案。 這里是：

FGalleryPhoto *photo = [_photoLoaders objectForKey:[NSString stringWithFormat:@"%i", index]];
UIImage *saveImage = [photo fullsize];

Answer 3

在上面的代碼中，在stringWithFormat方法中，將索引替換為_currentIndex

FGalleryPhoto *照片= [_photoLoaders objectForKey：[NSString stringWithFormat：@“％i”，_currentIndex]]; UIImage * saveImage = [全圖];
