Question

I have a problem regarding to set UIButton frame.

     NSString *sample = @"Demo to set display view on label in iPhone";

     CGSize maximumLabelSize = CGSizeMake(55,9999);
     expectedLabelSize = [sample sizeWithFont:[UIFont systemFontOfSize:20] 
                                              constrainedToSize:maximumLabelSize 
                                              lineBreakMode:UILineBreakModeWordWrap];

     NSLog(@"%f",expectedLabelSize.height);


    self.label = [[UILabel alloc] initWithFrame:CGRectMake(50, 50, expectedLabelSize.width, expectedLabelSize.height)];
    self.label.backgroundColor = [UIColor clearColor];
    self.label.numberOfLines = 0;
    self.label.text = sample;
    [self.label sizeToFit];

So in below uibutton code how to set frame position of text so that only “iPhone” word is clickable?

    self.button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
self.button.frame = CGRectMake(self.label.frame.origin.x, 
                               self.label.frame.origin.y+50, 
                               expectedLabelSize.width,
                               expectedLabelSize.height);

Answer 1

To make just one word of a UILabel clickable as a hyperlink you would need to know exactly where the UILabel puts that word. That is difficult (not impossible) especially with a multiple line label and especially if you allow resizing of the font to make the text fit.

Why not use a UIWebView and make it a hyperlink instead? Or separate the text that is clickable and put that text into the UIButton by itself, like:

label.text = @"Demo to set display view on label in ";
button.titleLabel.text = @"iPhone";

Note: you should not checkmark this answer if your problem is not solved.
