iphone - 以编程方式创建 UILabel

Question

我通过代码执行了以下操作:

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];

看起来像this但我希望它看起来像 this 。如何更改标签的属性？

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];
