Line break mode and adjustsFontSizeToFitWidth not working obj c - ios

Question

I am populating a view with multiple buttons (number of buttons is varying. Size of buttons and button titles is varying). I need to set button titles in 2 lines or 1 line according to number of words in the title. Also the font size should be compatible with the button frame size. Including some of my code here.
`
// --------------------------
button1.titleLabel.font = [UIFont fontWithName:#"ProximaNovaSoft-Bold" size:35];
button1.titleLabel.numberOfLines=0;
button1.titleLabel.lineBreakMode= NSLineBreakByWordWrapping;
button1.titleLabel.adjustsFontSizeToFitWidth=YES;
[button1.titleLabel setTextAlignment: NSTextAlignmentCenter];
// --------------------------
[button1 setBackgroundImage:[UIImage imageNamed:imgColor1] forState:UIControlStateNormal];
[self.view addSubview:button1];
button2 = [[UIButton alloc] init];
button2 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button2.tag=2;
[button2 addTarget:self
action:#selector(createAlert:)
forControlEvents:UIControlEventTouchUpInside];
button2.frame = CGRectMake(self.view.bounds.size.width/6-5, button1.frame.origin.y+(button1.frame.size.height/3)+button1.frame.size.height/2+15, self.view.bounds.size.width/3, self.view.bounds.size.width/3);
NSString *imgColor2 = [alertColorArray objectAtIndex:1];
if ([imgColor2 isEqualToString:#"RED"] || [imgColor2 isEqualToString:#"BLUE"] || [imgColor2 isEqualToString:#"YELLOW"]) {
imgColor2 = [imgColor2 stringByAppendingString:#".png"];
}
else
{
imgColor2 = #"YELLOW.png";
}
[button2 setTitle:[alertNameArray objectAtIndex:1] forState:UIControlStateNormal];
[button2 setTintColor:[UIColor whiteColor]];
button2.titleLabel.font = [UIFont fontWithName:#"ProximaNovaSoft-Bold" size:25];
// --------------------------
// button2.titleLabel.lineBreakMode= NSLineBreakByWordWrapping;
button2.titleLabel.numberOfLines=2;
button2.titleLabel.adjustsFontSizeToFitWidth=YES;
// --------------------------
[button2.titleLabel setTextAlignment: NSTextAlignmentCenter];
[button2 setBackgroundImage:[UIImage imageNamed:imgColor2] forState:UIControlStateNormal];
[self.view addSubview:button2];
`
But this is not working as I need. What wrong with this?

Answer 1

try,
//change scale factor accordingly
[LABEL setMinimumScaleFactor:12.0/[UIFont labelFontSize]];

Answer 2

Solved this by counting number of words in the text and numberoflines is set accordingly.button1.titleLabel.numberOfLines=[self wordCount:[alertNameArray objectAtIndex:0]];
