iphone - 如何在自动收缩标签后添加 UILabel 而不会重叠第二个标签

Question

我正在 iPhone 视图中处理标签，第一个是根据从远程 Web 服务获取的字符串内容自动调整大小的，尽管我UILabel旁边还有另一个，但是当第一个标签文本变得很长时，它与最后一个标签重叠，如何我能避免吗...

Answer 1

如果您通过 interface-builder 创建了标签

创建两个UILabel IBOutlet 属性作为 lbl1 和 lbl2。然后将 IBOutlet 连接到界面生成器。然后在viewDidLoad中编写如下代码

[lbl1 setNumberOfLines:0];
lbl1.lineBreakMode = UILineBreakModeWordWrap;
[lbl1 sizeToFit];
lbl1.text = @"your text here";

lbl2.frame =  CGRectMake(lbl1.frame.origin.x + lbl1.frame.size.width,  lbl1.frame.origin.y + lbl1.frame.size.height, 100, 50)];    
[lbl2 setNumberOfLines:0];   
lbl2.lineBreakMode = UILineBreakModeWordWrap;   
[lbl2 sizeToFit];
lbl2.text = @"your text here";

然后不要忘记再次编写/执行/调用代码 lbl2.frame = CGRectMake(lbl1.frame.origin.x + lbl1.frame.size.width, lbl1.frame.origin.y + lbl1.frame.size.高度, 100, 50)]; 同时将文本分配给 lbl1。

如果您通过代码创建标签

下面的代码对我有用

- (void)viewDidLoad {

    //Adding first label
    UILabel* lbl1 = [[UILabel alloc]initWithFrame:CGRectMake(0, 10, 100, 50)];
    lbl1.text = @"vbdsbfdshfisdhfidshufidhsufhdsf dhdsfhdksbf hfsdh fksdfidsf sdfhsd fhdsf sdhfh sdifsdkf ksdhfkds fhdsf dsfkdsfkjdhsfkjdhskfjhsdk fdhsf vbdsbfdshfisdhfidshufidhsufhdsf dhdsfhdksbf hfsdh fksdfidsf sdfhsd fhdsf sdhfh sdifsdkf ksdhfkds fhdsf dsfkdsfkjdhsfkjdhskfjhsdk fdhsf";
    [lbl1 setMinimumFontSize:8.0];
    [lbl1 setNumberOfLines:0];
    [lbl1 setFont:[UIFont systemFontOfSize:10.0]];
    lbl1.lineBreakMode = UILineBreakModeWordWrap;
    lbl1.backgroundColor = [UIColor redColor];
    [lbl1 sizeToFit];
    [self.view addSubview:lbl1];

    //Adding second label
    UILabel* lbl2 = [[UILabel alloc]initWithFrame:CGRectMake(lbl1.frame.origin.x + lbl1.frame.size.width, lbl1.frame.origin.y + lbl1.frame.size.height, 100, 50)];  
    lbl2.text = @"vbdsbfdshfisdhfidshufidhsufhdsf dhdsfhdksbf hfsdh fksdfidsf sdfhsd fhdsf sdhfh sdifsdkf ksdhfkds fhdsf dsfkdsfkjdhsfkjdhskfjhsdk fdhsf vbdsbfdshfisdhfidshufidhsufhdsf dhdsfhdksbf hfsdh fksdfidsf sdfhsd fhdsf sdhfh sdifsdkf ksdhfkds fhdsf dsfkdsfkjdhsfkjdhskfjhsdk fdhsf";
    [lbl2 setMinimumFontSize:8.0];
    [lbl2 setNumberOfLines:0];
    [lbl2 setFont:[UIFont systemFontOfSize:10.0]];
    lbl2.lineBreakMode = UILineBreakModeWordWrap;
    lbl2.backgroundColor = [UIColor redColor];
    [lbl2 sizeToFit];
    [self.view addSubview:lbl2];

    [lbl1 release];
    [lbl2 release]; 

    [super viewDidLoad];
}
