【问题描述】：

我有一个 UILabel 并且它应该显示文本它将是多长时间。所以 UILineBreakModeWordWrap 的概念已经消失但它对我不起作用..如果文本不适合该行那么它应该自动出现在下一行

UILabel *lblMyLable = [[[UILabel alloc] initWithFrame:CGRectMake(10,118, 600, 40)]autorelease];
    lblMyLable.lineBreakMode = UILineBreakModeWordWrap;
    lblMyLable.numberOfLines = 0;//Dynamic
    lblMyLable.tag=1301;
    lblMyLable.backgroundColor = [UIColor clearColor];
    lblMyLable.text = [NSString stringwithformat:@"%@ %@ %@ %@ %@ %@",id,name,address,city,state,country];
    [self.view addSubview:lblMyLable];

但是在这里显示 id、name 和 address 之后，剩下的部分被剪掉了..我看不到它..我的搜索方式是，如果不适合一行，那么它应该从第一行停止的位置开始自动跳转到下一行。我该怎么做？

NSString *str2 = @"xyz";

UILabel *lblMyLable = [[UILabel alloc] initWithFrame:CGRectMake(10,10, 200, 40)];

lblMyLable.numberOfLines = 0;

lblMyLable.backgroundColor = [UIColor clearColor];

lblMyLable.text = [NSString stringWithFormat:@"%@,%@,%@,%@,%@,%@,%@,%@",str,str1,str2,str3,str4,str5,str6,str7];

[lblMyLable sizeToFit];

[self.view addSubview:lblMyLable];

@arizah：在 lblMyLable.text 中写数百行并检查它。它运行良好。

【解决方案2】：

UILable 的高度太小，看不到线条

将高度设置为大于40的小瓶

UILabel *lblMyLable = [[UILabel alloc] initWithFrame:CGRectMake(10,118, 600, 240)];

这对你有帮助

lblMyLable.numberOfLines = 0;
