ios - 制作屏幕截图时隐藏按钮 UIGraphicsBeginImageContextWithOptions

Question

在使用 UIGraphicsBeginImageContextWithOptions 截屏时，是否有隐藏特定按钮(IBAction)的方法？

我正在使用下面的代码:

 // Define the dimensions of the screenshot you want to take (the entire screen in this case)
    UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
    [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *sourceImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    //now we will position the image, X/Y away from top left corner to get the portion we want
    UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0);
    [sourceImage drawAtPoint:CGPointMake(0, -20)];
    UIImage *croppedImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    UIImageWriteToSavedPhotosAlbum(croppedImage,nil, nil, nil);

谢谢您的回答!

为您 View 上的每个按钮添加 outlet 并设置 Hidden = YES,

否则你可以这样做

for(UIView *v in self.view.subviews){
    if([v isKindOfClass:[UIButton class]])
        [v setHidden:YES];
}
