Changing frame of view loaded from Xib

Question

I am trying to change the frame of my custom view which I load from a xib.

Here is my init method of the view:

- (id)initWithUserName:(NSString*)userName andComment:(NSString*)comment
{

    if (self) {
        self = [[[NSBundle mainBundle] loadNibNamed:@"Comment" owner:self options:nil]objectAtIndex:0];

        self.userName = userName;
        self.comment = comment;
        NSLog(@"CREATED");
        NSLog(@"%@, %@",self.userName, self.comment);

        self.userNameButton.tag = -1;

        CGSize constraint = CGSizeMake(240, 2000);
        self.userNameButton.backgroundColor = [UIColor clearColor];
        CGSize sizeOfUsernameText = [self.userName sizeWithFont:[UIFont fontWithName:@"OpenSans-Light" size:12.0] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

        //color converted from #161616 Hex
        [self.userNameButton.titleLabel setTextColor:[StaticMethods colorFromHexString:@"#161616"]];
        [self.userNameButton setTitle:[self.userName stringByAppendingString:@":"] forState:UIControlStateNormal];
        [self.userNameButton.titleLabel setFont:[UIFont fontWithName:@"OpenSans-Light" size:12.0]];
        [self.userNameButton setNeedsDisplay];

        //[self.userNameButton addTarget:self.delegate action:@selector(userNameButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
        //Append appropriate amount so that the usernames can be seen and clickable
        NSString *indentString = @" ";
        CGSize sizeOfWhitespaces = [indentString sizeWithFont:[UIFont fontWithName:@"OpenSans-Light" size:12.0] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
        while (sizeOfWhitespaces.width < sizeOfUsernameText.width) {
            sizeOfWhitespaces = [indentString sizeWithFont:[UIFont fontWithName:@"OpenSans-Light" size:12.0] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
            indentString = [indentString stringByAppendingString: @" "];

        }
        CGSize sizeOfComment = [comment sizeWithFont:[UIFont fontWithName:@"OpenSans-Light" size:12.0] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];

        self.commentText.tag = -1;
        self.commentText.text = [indentString stringByAppendingString: self.comment];
        self.commentText.font = [UIFont fontWithName:@"OpenSans-Light" size:12.0];
        [self.commentText setTextColor:[StaticMethods colorFromHexString:@"#161616"]];

    }

    return self;
}

This method is called from a view controller like this:

- (void)viewDidLoad
{
    [super viewDidLoad];
    for(int i = 0; i < self.userNames.count;i++){
        CommentView *view = [[CommentView alloc]initWithUserName:[self.userNames objectAtIndex:i] andComment:[self.comments objectAtIndex:i]];
        [view setDelegate: self];
        [self.view addSubview:view];
        view.frame = CGRectMake(0,100,320,100);


    }

    // Do any additional setup after loading the view from its nib.
}

Now, the line where it says view.frame = CGRectMake(0,100,320,100); is where i try to change the views frame. I have tried putting that code inside the view's

- (id)initWithUserName:(NSString*)userName andComment:(NSString*)comment

method body as well , without luck.

So clearly I am having trouble resizing the view according to my preferences. The view has always the same frame as when it is presented in interface builder.

What am I doing wrong?

EDIT

I have tried putting the above viewDidLoad body inside that viewcontroller's viewWillAppear body, without any progress.

Answer 1

在.xib中禁用“使用Autolayout”解决了这个问题。

Answer 2

put your code inside

- (void)viewDidLayoutSubviews
{

}

it is a delegate method executes only after autolayout has executed.
