Question

我正在尝试更改从xib加载的自定义视图的框架。

以下是我的视图初始化方法：

- (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;
}

从这样的视图控制器调用此方法：

- (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.
}

现在，它所在的行view.frame = CGRectMake(0,100,320,100);是我尝试更改视图框架的位置。 我已尝试将该代码放入视图的

中

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

方法正文，没有运气。

很明显，我无法根据自己的喜好调整视图大小。视图始终与界面构建器中显示的帧相同。

我做错了什么？

修改

我尝试将上面的viewDidLoad主体放在该viewcontroller的viewWillAppear主体中，没有任何进展。

Answer 1

在.xib中禁用“使用Autolayout”解决了这个问题。

Answer 2

将您的代码放入

- (void)viewDidLayoutSubviews
{

}

只有在执行autolayout后才会执行委托方法。
