iOS create UILabels dynamically
提问by Peter Warbo
Sometimes I want my view to contain 5 UILabels, sometimes 3 and sometimes n.
有时我希望我的视图包含 5 UILabels，有时是 3 ，有时是n。
The number of UILabels depends on data that's fetched from a website.
UILabel 的数量取决于从网站获取的数据。

You'll have to make them in code instead of interface builder
你必须用代码而不是界面构建器来制作它们
for (int i = 0; i < n; i++)
{
UILabel *label = [[UILabel alloc] initWithFrame: CGRectMake(/* where you want it*/)];
label.text = @"text"; //etc...
[self.view addSubview:label];
[label release];
}

NSArray *dataArray;
float xCoordinate=10.0,yCoordinate=10.0,width=100,height=40;
float ver_space=20.0;
for (int i = 0; i <dataArray.count; i++)
{
UILabel *label = [[UILabel alloc] initWithFrame: CGRectMake(xCoordinate,yCoordinate,width,height)];
label.text = [dataArray objectAtIndex:i];
[self.view addSubview:label];
yCoordinate=yCoordinate+height+ver_space;
}

UILabel *lbl=[[UILabel alloc]initWithFrame:CGRectMake(125, 12,170,20)];
lbl.text=@"IOS";
lbl.textAlignment = NSTextAlignmentCenter;
lbl.textColor = [UIColor whiteColor];
lbl.font = [UIFont fontWithName:@"AlNile" size:10.0];
lbl.backgroundColor=[[UIColor redColor]colorWithAlphaComponent:0.5f];
lbl.layer.borderColor=[UIColor blackColor].CGColor;
lbl.layer.borderWidth=1.0f;
lbl.layer.cornerRadius = 6.0f;
[self.view addSubview:lbl];
