How to increase size of UIView inside viewDidLoad method?

I am very new in ios application. I have 3 views on my main view. These views are representing a graph. anytime user opens main view (I mean each time viewDidLoad gets called) I need to measure some numbers and draw these graphs according to them. I only need to change the width of the graph! However I tried to manually add size to one of the graph but did not change at all! any suggestion will be appreciated.

As you can see I have added 100 here

self.timerGraph.frame.size.width+100


self.timerGraph.frame = CGRectMake(self.timerGraph.frame.origin.x,self.timerGraph.frame.origin.y,self.timerGraph.frame.size.width+100,self.timerGraph.frame.size.height);

But it is not affected!

Edit: I used this but Ben is printing but the width is not changing!!

- (void)viewWillAppear:(BOOL)try{

    NSLog(@"Ben");
    self.bestGraph.frame = CGRectMake(self.bestGraph.frame.origin.x,self.timerGraph.frame.origin.y,self.timerGraph.frame.size.width+130,self.timerGraph.frame.size.height);

}

Edit: I have deleted some implementation parts to make it shorter.

- (void)viewDidLoad
{


    NSNumber *min = [NSNumber numberWithInt:0];
    NSNumber *max = [NSNumber numberWithInt:0];
    NSNumber *avg = [NSNumber numberWithInt:0];
    NSNumber *total = [NSNumber numberWithInt:0];


    [super viewDidLoad];
    bool first = true;
    //Find the worst and best and average graph
    for(int i=0;i<tmp.numberOfTimes;i++)
    {
        //LTTime *myTime = [[LTTime alloc] init];
        LTTime *tmpTime = [tmp timeAtIndex:i];
        if(first)
        {
            first = false;
            min = tmpTime.time;
        }
        if(min>tmpTime.time)
        {
            min = tmpTime.time;
        }
        if(max<tmpTime.time)
        {
            max = tmpTime.time;
        }
        total = @( [tmpTime.time intValue] + [total intValue] );

    }
    avg = @( [total floatValue]/tmp.numberOfTimes);

    self.bestGraph.frame = CGRectMake(self.bestGraph.frame.origin.x,self.timerGraph.frame.origin.y,self.timerGraph.frame.size.width+130,self.timerGraph.frame.size.height);

    }

Definition of view:

@property (weak, nonatomic) IBOutlet UIView *bestGraph;

I don't know whether it is true according to your project.

Try the same code in viewWillAppear instead of viewDidLoad.

viewDidLoad calls only once when the app runs for the first time.

Hope it will helpful for you. Thank you :)

The problem was ios autolayout was ticked so I was not able to add in that way. So I decided to create my own view and anytime it goes to ViewWillAppear delete everything from view and add them again (because the view was changing more often).

I think it is better to learn how to create GUI elements by hand instead of IButton.

Try to put your code in

 - (void)viewWillLayoutSubviews

method.
