文字不适合UILabel Swift [英] Text not fitting in UILabel Swift

问题描述

我正在将json数据放入uiwebview中(通过情节提要添加)，如果json数据为空，则我将添加一个子视图(以编程方式添加).在该子视图中，我将添加标签.

i am getting json data into uiwebview(which is added through storyboard) and if the json data is empty i am adding a subview(which is added programatically).and in that subview i am adding a label.

当我运行它时，我可以看到子视图和标签，但是它的大小很大，所以它超出了子视图.我的代码是

when i run it i can see the subview and the label but its size is big, so it goes out of the subview. The code i have is

var detailView = UIView(frame: CGRectMake(0, 143, 568, 376)) //Overlapping the UIWebview
//detailView.backgroundColor = UIColor.blackColor()
detailView.contentMode = UIViewContentMode.ScaleAspectFit
detailView.autoresizingMask = UIViewAutoresizing.FlexibleBottomMargin | UIViewAutoresizing.FlexibleHeight | UIViewAutoresizing.FlexibleLeftMargin | UIViewAutoresizing.FlexibleRightMargin | UIViewAutoresizing.FlexibleTopMargin | UIViewAutoresizing.FlexibleWidth
self.view.addSubview(detailView)
var descLabel = UILabel(frame: CGRectMake(0, 0, 200, 200))

descLabel.textColor = UIColor.redColor()
descLabel.font = UIFont(name:"HelveticaNeue;", size: 6.0)
descLabel.text = "No Description was found" +
                        " for \(self.strFullName)" +
                        " please try again later"
descLabel.textAlignment = NSTextAlignment.Center
descLabel.contentMode = UIViewContentMode.ScaleAspectFit
descLabel.autoresizingMask = UIViewAutoresizing.FlexibleBottomMargin | UIViewAutoresizing.FlexibleHeight | UIViewAutoresizing.FlexibleLeftMargin | UIViewAutoresizing.FlexibleRightMargin | UIViewAutoresizing.FlexibleTopMargin | UIViewAutoresizing.FlexibleWidth
detailView.addSubview(descLabel)

当我在模拟器上运行它时，我看到"No Description was fou ..."，其余内容都在屏幕上消失了.从上面的代码中可以看到，我尝试设置字体大小，字体大小也没有改变，并且尝试将其放在不同的行上

When i run it on the simulator i see "No Description was fou..." and the rest of it is gone of the screen. as you can see from above code i have tried to set the font size, the font size does not change either, and also try to put it on different lines

我在做错什么导致标签显示为这样?以及我该如何解决.

What am i doing wrong which is causing the label to display like this? And how can i fix it.

在此先感谢您提供的帮助

Thank you in advance for any help provided

推荐答案

解决方案是使标签与descLabel.numberOfLines = 0多行，并确保其宽度不大于屏幕宽度.

The solution is to make the label multi-line with descLabel.numberOfLines = 0, and make sure that its width is not larger than screen width.
