How to change UIView size?

Question

I need to update UIView size.

Now i use

var titleSize = CGRectMake(0, 30, 40 , 1000)

self.contentCoverScrollView.frame = titleSize

in viewDidLoad, but nothing happens.

Are you using AutoLayout in your project?

In Autolayout if you want to change the frame then try the constraints (IBOutlet of NSLayoutConstraint).

enter image description here

Set the constraint outlets and change constant value by :

self.sampleConstraint.constant = 20
self.view.layoutIfNeeded()

I thought you had used the AutoLayout in your application that's why it can not change the view frame, please write the below code.

var titleSize = CGRectMake(0, 30, 40 , 1000)

self.contentCoverScrollView.frame = titleSize

[self.contentCoverScrollView updateConstraintsIfNeeded];

Note : updateConstraintsIfNeeded will tell the system to recalculate the constraints in that particular moment of execution.

Look like you want to change ScrollView size use:

[self.contentCoverScrollView setContentSize:(CGSizeMake(40, 1000))];

In Swift: self.contentCoverScrollView.contentSize = CGSize(width:40, height: 1000)
