Xcode 4.2 - UILabel Word Wrap [英] Xcode 4.2 - UILabel Word Wrap

问题描述

我知道人们已经在Stack上多次问过这个问题，但通常的答案是更改Lines：0并选择Line Breaks：Word Wrap，这对我来说并不是很有用。

I know people have asked this question a bunch of times alrdy on Stack, but the usual answer of changing "Lines: 0" and selecting "Line Breaks: Word Wrap" just isn't fixing it for me.

我正在使用Xcode 4.2和Storyboard。我在视图控制器上放置了一个UILabel，并将其调整大小以覆盖大部分视图。我已将Lines值更改为0，将Line Breaks值更改为Word Wrap。

I am using Xcode 4.2 with a Storyboard. I have placed a UILabel on a View Controller and resized it to cover most of the View. I have changed "Lines" value to 0 and "Line Breaks" value to Word Wrap.

我在我的字符串中尝试过 \ n ： @这是我的标签文本\ n应该包装。

I have tried \n in my string: @"This is my label text \n that's supposed to wrap."

任何想法？

编辑：我没有在我的实现文件中声明任何标签的属性，只是在故事板上，所以我尝试了以下......但没有运气; \（字体名称和大小以及对齐工作，但行数和中断模式似乎什么都不做。）

I wasn't declaring any of the label's properties in my implementation file, only on the storyboard, so I have tried the following... But with no luck ;\ (font name and size and alignment work, but number of lines and break mode seem to do nothing.)

lblText.numberOfLines = 0;

lblText.font = [UIFont fontWithName：@Helvetica尺寸：（15.0）];

lblText.lineBreakMode = UILineBreakModeWordWrap;

lblText.textAlignment = UITextAlignmentLeft;

推荐答案

试试这个

[lblText setFrame:CGRectMake(10, 21, 100, 250)];
lblText.text =@"This is my label text \n that's supposed to wrap.";
lblText.numberOfLines = 3;
lblText.font = [UIFont fontWithName:@"Helvetica" size:(15.0)];
lblText.lineBreakMode = UILineBreakModeWordWrap;
lblText.textAlignment = UITextAlignmentLeft;
