我需要的UIView动态大小(它可以方含1个或2个标签),我做这样的事情:添加子视图到UIView后,我可以为UIView设置框架吗?
float nextY = 0.0f;
float labelHeight = 20.0f;
UIView *tempView = [[UIView alloc] initWithFrame:CGRectZero];
UILabel *label1 = [[UILabel alloc] initWithFrame:CGRectMake(0.0f, nextY, 100.0f, labelHeight)];
label1.text = @"Test 1";
[tempView addSubview:label1];
nextY += labelHeight;
if (something == YES)
{
UILabel *label2 = [[UILabel alloc] initWithFrame:CGRectMake(0.0f, nextY, 100.0f, labelHeight)];
label1.text = @"Test 2";
[tempView addSubview:label2];
nextY += labelHeight;
}
tempView.frame = CGRectMake(0.0f, 0.0f, 100.0.f, nextY);
我可以吗?
当然,实际上只是点击运行而不是登录并提出这个问题会更快? – 2012-01-14 17:27:01
嗯,是的,我知道它的工作原理,但我只是想知道这是否是正确的做法... – 2012-01-14 17:29:46
