创建UILabel
self.lbl=[[UILabel alloc] initWithFrame:CGRectMake(135, 290,200,35)];
self.lbl.backgroundColor=[UIColor clearColor];
NSString *str=[NSString stringWithFormat:@"%.f",[self.slider value]];
[self.lbl setFont:[UIFont fontWithName:@"Arial-BoldMT" size:16]];
self.lbl.text=str;
[self.View addSubview:self.lbl];
点击UIButton时修改UILabel文本尺寸
-(IBAction)ButtonPressed:(id)sender
{
[self.lbl setFont:[UIFont fontWithName:@"Arial-BoldMT" size:25]];
