在iOS SDK中将标签文本显示为段落

Question

我想显示如下的文本。

我的标签内容可能会更改，并且标签框应自动调整。

我怎样才能做到这一点？

我的尝试

//NSString* string = @"Previously scheduled for every Monday, Happy will now be moving to Wednesdays at the same time. The time from 5:00 pm - 7:00 pm will remain the same. Now starting April 14th until further notice.";

   NSString* string=@"ABCDEF";
    NSMutableParagraphStyle *style  = [[NSMutableParagraphStyle alloc] init];
    style.minimumLineHeight = 30.f;
    style.maximumLineHeight = 30.f;
    style.firstLineHeadIndent=100.0f;
    NSDictionary *attributtes = @{NSParagraphStyleAttributeName : style,};
    lbl_notification.attributedText = [[NSAttributedString alloc] initWithString:string attributes:attributtes];

Answer 1

设置标签文字

Yourlabel.text=[NSString stringWithFormat:@"Notification:    %@",Dynamic text];

Yourlabel.adjustsFontSizeToFitWidth = YES;

Answer 2

尝试此操作，如果文本过多，则会缩小字体大小，以使其适合标签：

 displayLabel.adjustsFontSizeToFitWidth = YES;

Answer 3

这对我有用：

     _label = [[UILabel alloc] init];
     _label.lineBreakMode = NSLineBreakByWordWrapping;
     _label.numberOfLines = 0;
    _label.text = .....
    [_label setFrame:CGRectMake(0.0f, 0.0f, 340.0f, 300.0f)];
    _labelSize = [_label.text sizeWithFont:_label.font constrainedToSize:_label.frame.size lineBreakMode:NSLineBreakByWordWrapping];
    [_label setFrame:CGRectMake(0.0f, 0.0f, 340.0f, _labelSize.height)];

Answer 4

如果您希望根据文本更改标签框架，以下代码将很有帮助，

CGSize Size1 = yourlabel.bounds.size;
CGSize Size2 = CGRectInfinite.size;
Size2.width = Size1.width;

Size2 = [yourlabel.text sizeWithFont:yourlabel.font constrainedToSize:Size2];

yourlabel.frame = CGRectMake(yourlabel.frame.origin.x, yourlabel.frame.origin.y, Size2.width, Size2.height);
