[英]How do I save an image with a label on it to the photo album?
Im making a camera app and I want to add a label to the pictures that are taken like in the app MSQRD and save to the photo album. 我正在制作一个相机应用程序,我想为在应用程序MSQRD中拍摄的照片添加标签,然后保存到相册中。 I got the label to display on to the image but when I go to the photo album it shows an image but without the label.
我得到了要显示在图像上的标签,但是当我进入相册时,它显示的是图像但没有标签。 What am I doing wrong with my code.
我的代码在做什么错。 Here is the code that Im using currently:
这是我当前使用的代码:
@IBAction func takePicture(sender: AnyObject) {
if let videoConnection = stillImageOutput!.connectionWithMediaType(AVMediaTypeVideo) {
videoConnection.videoOrientation = AVCaptureVideoOrientation.Portrait
stillImageOutput?.captureStillImageAsynchronouslyFromConnection(videoConnection, completionHandler: {(sampleBuffer, error) in
if (sampleBuffer != nil) {
let imageData = AVCaptureStillImageOutput.jpegStillImageNSDataRepresentation(sampleBuffer)
let dataProvider = CGDataProviderCreateWithCFData(imageData)
let cgImageRef = CGImageCreateWithJPEGDataProvider(dataProvider, nil, true, CGColorRenderingIntent.RenderingIntentDefault)
let image = UIImage(CGImage: cgImageRef!, scale: 1.0, orientation: UIImageOrientation.Right)
//edited this part it saves the entire view in the photo album except for the image that was taken and the label.
UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0)
self.view.layer.renderInContext(UIGraphicsGetCurrentContext()!)
let newImage: UIImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
//saves captured picture to camera roll.
UIImageWriteToSavedPhotosAlbum(newImage, nil, nil, nil)
//fade in the image that was taken
UIView.animateWithDuration(0.5, delay: 0.1, options: UIViewAnimationOptions.CurveLinear, animations: {
self.capturedImage.image = image
self.capturedImage.alpha = 1.0
}, completion: nil)
}
}
}
You made the capturedImage
from UIGraphicsImageContext
, but never used. 您是从
UIGraphicsImageContext
capturedImage
,但从未使用过。 Change UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil)
to UIImageWriteToSavedPhotosAlbum(capturedImage, nil, nil, nil)
. 将
UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil)
更改为UIImageWriteToSavedPhotosAlbum(capturedImage, nil, nil, nil)
。
