iOS 截屏并保存图片

在应用内截取屏幕

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

CGRect screeRect = [view bounds];

UIGraphicsBeginImageContext(screeRect.size);

CGContextRef ctx = UIGraphicsGetCurrentContext();

[view.layer renderInContext:ctx];

UIImage *image = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

return image;

}

保存图片在本地相册中

UIImage *image = [self captureImageFromView:self.view];

UIImageWriteToSavedPhotosAlbum(image, nil, nil, nil);
