Appending UIButton with NSString - iphone

Question

I have this code to show some text in a textview from SQLite DB..
NSMutableString *combined = [NSMutableString string];
for(NSUInteger idx = 0; idx < [delegate.allSelectedVerseEnglish count]; idx++) {
[combined appendFormat:#" %d %#", idx, [delegate.allSelectedVerseEnglish objectAtIndex:idx]];
}
self.multiPageView.text = combined;
self.multiPageView.font = [UIFont fontWithName:#"Georgia" size:self.fontSize];
delegate.allSelectedVerseEnglish is the NSArray
multiPageView is the UITextView
i put the above loop function to get the Numbers according to the text,for example 1 hello 2 iPhone 3 iPad 4 mac etc etc..i just want UIButton between the text instead of 1 2 3 4 ..for example i want unbutton hello unbutton iPhone etc etc.because i need to make some touch events from it.how to do this?
Thanks in advance.

Answer 1

If you want to place UIButtons between some text in textview, there is no other way but to place it as a separate view just above. So you'll need to add spaces beneath those buttons, the amount of those you should calculate yourself, based on the size of your buttons.
So, if you would like yo see something like this:
Press here [UIButton] or here [Another UIButton],
your text string should look like this
Press here or here ,
So when you add the buttons on those places, it would look just like you wish.
UPDATE
Seems like we need some more code here, so here it is:
First, you'll need to calculate the size of a letter. Let's assume that it is 10 pixels height and 8 pixels.No, let's just call that letterHeight and letterWidth.Let's also assume that you want 64x10 pixels buttons. So, we will need 64/8=8 +2 spaces to out behind that button(2 to make borders around that)
So, here we go
NSMutableString *combined = [NSMutableString string];
int letterHeight = 10;
int letterWidth = 8;
for(NSString *verse in delegate.allSelectedVerseEnglish) {
[combined appendFormat:#" %#",verse];//10 spaces there
//You have to experiment with this, but idea is that your x coordinate is just proportional to the length of the line you are inserting your button in, and y is proportional to number of lines
int xCoordinate = [combined length]*letterWidth%(int)(self.multiPageView.frame.size.width);
int yCoordinate = [combined length]*letterWidth/(int)(self.multiPageView.frame.size.width)*letterHeight;
UIButton *newButton = [[UIButton alloc]initWithFrame:CGRectMake(xCoordinate,yCoordinate,64,10)];
[self.multiPageView addSubview:newButton];
}
self.multiPageView.text = combined;
