I need to merge betwwen UITexView text to UIImageView to one UIImage - objective-c

Question

I need to merge UITextView and UIImageView to one UIImage.
I try to convert UITextView (background color is clear) to UIImage but the background turn to black after this code.
#define IS_OS_7_OR_LATER ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0)
-(UIImage*)imageFromView:(UIView*)view
{
CGFloat scale = [UIScreen mainScreen].scale;
UIImage *image;
if (IS_OS_7_OR_LATER)
{
//Optimized/fast method for rendering a UIView as image on iOS 7 and later versions.
UIGraphicsBeginImageContextWithOptions(view.bounds.size, YES, scale);
[view drawViewHierarchyInRect:view.bounds afterScreenUpdates:YES];
image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
}
else
{
//For devices running on earlier iOS versions.
UIGraphicsBeginImageContextWithOptions(view.bounds.size,YES, scale);
[view.layer renderInContext:UIGraphicsGetCurrentContext()];
image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
}
return image;
}

-(UIImage*)imageFromView:(UIView*)view
{
CGFloat scale = [UIScreen mainScreen].scale;
UIImage *image;
UIGraphicsBeginImageContextWithOptions(view.bounds.size, NO, scale);
if ([view respondsToSelector:#selector(drawViewHierarchyInRect:afterScreenUpdates:)]) {
[view drawViewHierarchyInRect:view.bounds afterScreenUpdates:YES];
}else{
[view.layer renderInContext:UIGraphicsGetCurrentContext()];
}
image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
return image;
}
If you can change your method to the code above
(please note the correct way to change method according to OS - if class responds to that method check) -
The opaque boolean should be NO, where your code was asking the view to be opaque. Changing it to say NO should make it clear and solve your issue. I haven't had chance to test this code, though it should work. If not then at the very least the OS checking is better this way.
I hope this help
Thanks
