Question

在以下按钮中显示的是一个地址。我的问题是地址很长，如何在按钮标题中的两个变量之间得到一个断行线？

NSString *sitz = map.kordinate.herkunft;
NSString *strasse = map.kordinate.strasse;
NSString *strasseMitKomma = [strasse stringByAppendingString:@","];
NSString *fertigesSitzFeld = [strasseMitKomma stringByAppendingString:sitz];
UIButton *firmensitz = [UIButton buttonWithType:UIButtonTypeRoundedRect];

断裂线必须介于strasseMitKomma和sitz ??

之间

谢谢你的帮助

Answer 1

您必须在UIButton中配置UILabel以支持多行你可以这样做：

 NSString *address;

    address = [NSString stringWithFormat:@"%@,\n%@", @"street name", @"city name"];   // Note the \n after the comma, that will give you a new line

    addressButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];


    [addressButton.titleLabel setLineBreakMode:UILineBreakModeWordWrap];    // Enabling multiple line in a UIButton by setting the line break mode
    [addressButton.titleLabel setTextAlignment:UITextAlignmentCenter];

    [addressButton setTitle:address forState:UIControlStateNormal];

顺便说一下，你不需要那么多的NSString变量。您可以将新字符串的结果放在您已经使用的NSString变量中看看我的答案的第一行中的方法stringWithFormat。请阅读NSString documentation了解更多详情。

它适用于iOS9。

[_butNoReceipt.titleLabel setTextAlignment:NSTextAlignmentCenter];
[_butNoReceipt setTitle:btnTest forState:UIControlStateNormal];
