以编程方式创建UILabel

Question

我做了以下代码:

UILabel  * label = [[UILabel alloc] initWithFrame:CGRectMake(40, 70, 300, 50)];
    label.backgroundColor = [UIColor clearColor];
    label.textAlignment = UITextAlignmentCenter; // UITextAlignmentCenter, UITextAlignmentLeft
    label.textColor=[UIColor whiteColor];
    label.text = @"Telechargez et consultez les catalogues et les tarifs de la gamme Audi au format PDF";
    [self.view addSubview:label];

它看起来像这样, 但我希望它看起来像这样.如何更改标签的属性？

Answer 1

试试这个:

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(40, 30, 300, 50)];
    label.backgroundColor = [UIColor clearColor];
    label.textAlignment = NSTextAlignmentCenter;
    label.textColor = [UIColor whiteColor];
    label.numberOfLines = 0;
    label.lineBreakMode = UILineBreakModeWordWrap;
    label.text = @"Telechargez et consultez les catalogues et les tarifs de la gamme Audi au format PDF";
    [self.view addSubview:label];

Answer 2

要将UILable显示为在图像中显示,您需要设置UILabel的以下属性并增加Label的高度.

@property(nonatomic) NSInteger numberOfLines;
@property(nonatomic) UILineBreakMode lineBreakMode;

应如下所示..

    UILabel  * label = [[UILabel alloc] initWithFrame:CGRectMake(40, 70, 300, 100)];
     .................................
    label.numberOfLines=0;
    label.lineBreakMode=UILineBreakModeCharacterWrap;
    ............................
