如何在ios中採取特定對象截圖

Question

我是ios上的新開發者。我開發一個正常的地方，我使用一些按鈕和屏幕背景圖像。我可以用按鈕和背景截圖。現在我想要拍攝特定對象的屏幕截圖。能有可能在目標C

這是我的代碼

UIGraphicsBeginImageContext(self.view.bounds.size); 
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()]; 
UIImage * image = UIGraphicsGetImageFromCurrentImageContext(); 
UIGraphicsEndImageContext(); 

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(100, 100, 200, 200)]; 
imageView.layer.zPosition = 14; 
imageView.image = image; 
[self.view addSubview:imageView];

是下面提到美國可以採取特定對象的屏幕截圖： -

UIGraphicsBeginImageContextWithOptions(hiddenView.bounds.size, self.view.opaque, 0.0); //In this I have take screenshot of a hiddenView that I have added from IB with a background color anything(in this case it's orange). 
//Replace this hiddenView object with your object of whom you want to take screenshot. 

[hiddenView.layer renderInContext:UIGraphicsGetCurrentContext()]; //Similarly replace hiddenView here with your object. 

UIImage*theImage=UIGraphicsGetImageFromCurrentImageContext(); 
UIGraphicsEndImageContext(); 

NSData*theImageData=UIImageJPEGRepresentation(theImage, 1.0); 
imgView.image = [UIImage imageWithData:theImageData]; //I placed a UIImageView to check and place the screenshot into it as Image ,simply to cross check if I'm getting a right screenshot or not. 
//So you could also remove this line after your have verified that your getting right screen shot. 

別的然後讓我知道。
