Question

我是Xcode的新手，我正在尝试编写一个应用程序，允许用户使用相机，拍摄多张照片，然后允许用户选择他们想要附加到的图片 - app电子邮件。我收到的错误如下：

Incompatible pointer types passing "UIImagePickerController *" to parameter of type "UIImage *"

和

Instance method '_alloc' not found (return type defaults to 'id')

和

Incompatible pointer types sending 'UIImage *' to parameter of type 'NSString *'

和

Unused variable 'photoData'

这是我的代码

// Camera Control

-(void) takePhotoClicked
{
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera])

    {
        UIImagePickerController *theimagepicker = [[UIImagePickerController alloc] init];

        theimagepicker.delegate = self;

        theimagepicker.sourceType = UIImagePickerControllerSourceTypeCamera;
        theimagepicker.mediaTypes = @[(NSString *) kUTTypeImage] ;
        theimagepicker.allowsEditing = NO;
        [self presentModalViewController:theimagepicker animated:YES];
        [theimagepicker release];
        newMedia = YES;

    }
}

// Choose Photo Control

-(void) choosePhotoClicked
{
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeSavedPhotosAlbum])
    {
        UIImagePickerController *theimagepicker = [[UIImagePickerController alloc] init];

        theimagepicker.delegate = self;

        theimagepicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;

        theimagepicker.mediaTypes = @[(NSString *) kUTTypeImage];
        theimagepicker.allowsEditing = NO;
        [self presentModalViewController:theimagepicker animated:YES];
        // Save image
        UIImageWriteToSavedPhotosAlbum(theimagepicker, self, @selector(theimagepicker:didFinishSavingWithError:contextInfo:), nil);
        NSLog(@"Creating Mail Data!!!");
        NSData *photoData = [[UIImageJPEGRepresentation([UIImage imageNamed:@"qwerty.png"], 1) alloc] init];

        [theimagepicker release];
        newMedia = NO;

    }
}



// Image Delegate Methods

-(void)theimagepickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo: (NSDictionary *)info
{
    NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
    [self dismissModalViewControllerAnimated:YES];
    if ([mediaType isEqualToString:(NSString *)kUTTypeImage])
    {
        UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];

        theimageView.image = image;
        if (newMedia)
            UIImageWriteToSavedPhotosAlbum(image, self, @selector (image:finishedSavingWithError:contextInfo:), nil);


        NSLog(@"Creating Mail Data!!!");
        NSData *photoData = [[UIImageJPEGRepresentation([UIImage imageNamed:@"qwerty.png"], 1) alloc] init];


    }
    else if ([mediaType isEqualToString:(NSString *) kUTTypeMovie])
    {


        // Code here to support video if enabled
    }
}

-(void)image:(UIImage *)image
finishedSavingWithError:(NSError *)error
 contextInfo:(void *)contextInfo
{
    if (error) {
        UIAlertView *alert = [[UIAlertView alloc]
                              initWithTitle: @"Save failed"
                              message: @"Failed to save image"
                              delegate: nil
                              cancelButtonTitle:@"OK"
                              otherButtonTitles:nil];
        [alert show];
        [alert release];

    }

}

Answer 1

好的，在方法“choosePhotoClicked”中删除这些行

    UIImageWriteToSavedPhotosAlbum(theimagepicker, self, @selector(theimagepicker:didFinishSavingWithError:contextInfo:), nil);

    NSData *photoData = [[UIImageJPEGRepresentation([UIImage imageNamed:@"qwerty.png"], 1) alloc] init];

然后从“didFinishPicking ...”

中删除此行

    NSData *photoData = [[UIImageJPEGRepresentation([UIImage imageNamed:@"qwerty.png"], 1) alloc] init];

然后在动作“email”中替换此行：

    [composer addAttachmentData:photoData mimeType:@"image/jpg" fileName:[UIImage imageNamed:theimageView.image]];

使用这些行：

    NSData *imageData = UIImageJPEGRepresentation(theimageView.image, 1.0);
    [composer addAttachmentData:imageData mimeType:@"image/jpg" fileName:@"this is a string file name";
