上一次截屏的代码真是又丑又长，看看大神是怎么写的吧

- (nullable UIImage *)generateSnapshot:(CGSize)size{    self.addressLabelBg.hidden = YES;    self.addressLabel.hidden = YES;    self.mapView.showsUserLocation = NO;    CGPoint mapCenter = self.mapView.center;    UIGraphicsBeginImageContextWithOptions(size, NO, 0.0f);    [self.mapView drawViewHierarchyInRect:CGRectMake(-(mapCenter.x - size.width / 2),                                                     -(mapCenter.y - size.height / 2),                                                     self.mapView.bounds.size.width,                                                     self.mapView.bounds.size.height)                       afterScreenUpdates:YES];    UIImage *snapshotImage = UIGraphicsGetImageFromCurrentImageContext();    UIGraphicsEndImageContext();    self.addressLabelBg.hidden = NO;    self.addressLabel.hidden = NO;    self.mapView.showsUserLocation = YES;    return snapshotImage;}

其实重点还是截屏区域坐标的确定
