Answer 1

You can capture the contents of any UIView in a UIImage. First, create an empty UIView and put the UIImageView and UITextView as subviews:

// Assumes you have UIImageView *myImageView and UITextField *myTextField
UIView *parentView = [[UIView alloc] initWithFrame:CGRectZero];
[parentView addSubview:myImageView];
[myImageView setFrame:CGRectMake(0, 0, 100, 100)];
[parentView addSubview:myTextField];
[myTextField setFrame:CGRectMake(20, 20, 80, 20)];
[parentView sizeToFit];

Now create a graphical context and insert parentView into it:

UIGraphicsBeginImageContext([parentView bounds].size);
[[parentView layer] renderInContext:UIGraphicsGetCurrentContext()];
UIImage *outputImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
