Xcode 4.2 - UILabel Word Wrap

Question

我知道人们在Stack上已经多次问过这个问题了,但通常的答案是改变"Lines:0"并选择"Line Breaks:Word Wrap",这对我来说并不是很好.

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.

我试过\n我的字符串:@"This is my label text \n that's supposed to wrap."

有任何想法吗？？

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

lblText.numberOfLines = 0;
lblText.font = [UIFont fontWithName:@"Helvetica" size:(15.0)];
lblText.lineBreakMode = UILineBreakModeWordWrap;
lblText.textAlignment = UITextAlignmentLeft;

Answer 1

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;
