如何降低UIFont尺寸并显示大行UILabel iPhone？

Question

我的iPhone应用程序中有一个UILabel。我想在一行中用UILabel显示大句子。这意味着我想减小字体大小并在可见区域显示全文。我不想以多行显示它。有人可以帮我这样做吗？

我的代码是：

textViewLabel = [[UILabel alloc] initWithFrame:CGRectMake(8, 5, 194, 20)];
textViewLabel.text = @"I have an UILabel in my iPhone app. I have want";
textViewLabel.textColor = [UIColor lightGrayColor];
textViewLabel.font = [UIFont fontWithName:@"Helvetica" size:14];
textViewLabel.numberOfLines = 0;
textViewLabel.backgroundColor = [UIColor clearColor];

CGSize maximumLabelsize2 = CGSizeMake(194,20);
CGSize expectedLabelsize2 = [result sizeWithFont:textViewLabel.font constrainedToSize:maximumLabelsize2 lineBreakMode:textViewLabel.lineBreakMode]; 
CGRect messagesFrame = textViewLabel.frame;
messagesFrame.size.height = expectedLabelsize2.height;
textViewLabel.frame = messagesFrame; 

任何人请帮我这样做？提前谢谢。

Answer 1

从

更改numberOfLines属性

textViewLabel.numberOfLines = 0; // 0 means as many lines as needed

到

textViewLabel.numberOfLines = 1;

添加

textViewLabel.adjustsFontSizeToFitWidth = YES; 

考虑设置

textViewLabel.minimumFontSize = someValue; // default is 0.0

Answer 2

试试这个属性：

myLabel.adjustsFontSizeToFitWidth = YES;

Answer 3

试试这个：

[textViewLabel  setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
