ios - MultiLine UIlabel 不显示所有文本？

Question

我想根据我使用过的文本显示标签大小uilabel 行属性号。

lbl.numberoflines = 0;

但它只显示三行，然后显示...。并非所有文本都显示。

当我给出的行数超过 3 时，它会在标签中显示该行。

感谢帮助

试试这个

lbl.lineBreakMode = UILineBreakModeWordWrap;

lbl.numberOfLines = 0;

如果要手动计算高度

 lbl.numberOfLines = 0; // allows label to have as many lines as needed
lbl.text =@"xxxxxxxxxxxxxxxxxxxxxx";
CGSize labelSize = [ lbl.text sizeWithFont: lbl.font constrainedToSize:CGSizeMake(300, 300)  lineBreakMode:NSLineBreakByWordWrapping];

// set the frame of labels here 

否则你可以直接放在属性中

swift3

lbl.lineBreakMode = .byWordWrapping
lbl.numberOfLines = 0

// allows label to have as many lines as needed
lbl.text = "xxxxxxxxxxxxxxxxxxxxxx"
var labelSize = lbl.text.size(with: lbl.font, constrainedToSize: CGSize(width: 300, height: 300), lineBreakMode: .byWordWrapping)
// set the frame of labels here  }
