UIScrollView and UITextView autosizing possible?

I have a view that is pushed onto the Screen via navigation controllers:

Inside is a UIScrollView.

Then inside the UIScrollView are a few static objects like Images and Labels.

Then comes the hard bit, There is a UITextView with its text开发者_StackOverflow社区 loaded from different text files of varying length.

I need to be able to have the UITextView size dynamically to its contents, and the same for the UIScrollView. Is this possible?

float length = [yourText length];
textview.frame = CGRectMake(44, 87, 923, ceilf(length/142)*25);

Here 25 is the constant value assumed as text font width. From this you can set scrollview frame reference to the textview frame.

You can do that with the help of following code. I had done that code for Label and same way you can do that with the help of text-field.

NSString *cellText = "Text Of Your Text-Field";
UIFont *cellFont = [UIFont fontWithName:@"Your Font Name" size:FONT_SIZE];//UIFont *cellFont = [UIFont fontWithName:@"Helvetica-Bold" size:13.0];
CGSize constraintSize = CGSizeMake(@"Width Of Your Text-Field", MAXFLOAT);//CGSize constraintSize = CGSizeMake(220.0f, MAXFLOAT);
CGSize labelSize = [cellText sizeWithFont:cellFont constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap];

int height = labelSize.height;

frame.origin.x = Starting Position of X;
frame.origin.y = Starting Position of Y;
frame.size.width = Width Of Your TextField;
frame.size.height = height;

UILabel *lblName = [[[UILabel alloc] initWithFrame:frame] autorelease];
lblName.numberOfLines = 0;
lblName.lineBreakMode = UILineBreakModeWordWrap;
lblName.textAlignment = UITextAlignmentLeft;
lblName.textColor = [UIColor whiteColor];
lblName.backgroundColor = [UIColor clearColor];
lblName.font = [UIFont boldSystemFontOfSize:13.0];

And same way you can do For the Scrollview. Just you have to set the Frame of that scrollview and you are done.

Yes you could do something like this:

if ([textView length] > int//any number you want) {
    textView.frame = CGRectMake(//just adjust the size  an position here);
    scrollView.contentSize = CGSizeMake(//adjust scrollView size)
}
else if ([textView length] > int//just another number) {
    // you can continue looping that for how often you want
}

For the int in the if statement you check how long the text is. Based on that you adjust the size of both the scrollView and textView.
