IOS study note 63-Save the current image to the album

Codoon should stick to writing things to prevent the speed of the bald roof from accelerating!

I will start with this in 2104. I haven't written it for a long time. It's decadent...

//

-(UIImage *) captureCurrentView :( UIView *) view {

CGRect frame = view. frame;

UIGraphicsBeginImageContext (frame. size );

CGContextRef contextRef = UIGraphicsGetCurrentContext ();

[View. layerrenderInContext: contextRef];

UIImage * image = UIGraphicsGetImageFromCurrentImageContext ();

UIGraphicsEndImageContext ();

UIImage * saveImage = [UIImageimageWithCGImage: CGImageCreateWithImageInRect (image. CGImage, CGRectMake (, self. view. frame. size. width, self. view. frame. size. height)];

Return saveImage;

}

// Save the image

-(Void) saveImageToPhotos :( UIImage *) image {

UIImageWriteToSavedPhotosAlbum (image, self, @ selector (image: didFinishSavingWithError: contextInfo :), NULL );

}

// Save the callback

-(Void) image: (UIImage *) image didFinishSavingWithError: (NSError *) error contextInfo: (void *) contextInfo

{

NSString * msg = nil;

If (error! = NULL ){

Msg = @ "failed to save the image ";

} Else {

Msg = @ "image saved ";

}

}
