由于现在出现iPhone6以及iPhone6 plus大屏幕，所以我们进行布局时得考虑自适应，这是我昨天刚刚学习到得。必须得记录一下，希望对你们有帮助，如果有些地方用词不标准得还请提议下，谢谢了，
这是新建得viewcontroller 进行全局定义
接下来就是定义导航栏
然后现在定义一个方法，在方法下面添加以下代码
for (int i=0; i<12; i++) {
label = [[UILabel alloc] init];
bt = [UIButton buttonWithType:UIButtonTypeCustom];
if (i<4) {
bt.frame=CGRectMake((self.view.bounds.size.width-4*BW)/5+((self.view.bounds.size.width-4*BW)/5+60)*i,70, BW, BH);
label.frame=CGRectMake((self.view.bounds.size.width-4*BW)/5+((self.view.bounds.size.width-4*BW)/5+60)*i, 70+35, BW, BH);
label.text=@"label";
//label内容居中
label.textAlignment=NSTextAlignmentCenter;
label.adjustsFontSizeToFitWidth=YES;
label.numberOfLines=1;
bt.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:[NSString stringWithFormat:@"image%i.jpg",i]]];
bt.layer.cornerRadius=2.0;
//边框的大小
bt.layer.borderWidth=2.0;
//边框得颜色
bt.layer.borderColor=[[UIColor purpleColor] CGColor];
}else if (i<8){
bt.frame=CGRectMake((self.view.bounds.size.width-4*BW)/5+((self.view.bounds.size.width-4*BW)/5+60)*(i%4),BH+70+height, BW, BH);
label.frame=CGRectMake((self.view.bounds.size.width-4*BW)/5+((self.view.bounds.size.width-4*BW)/5+60)*(i%4), BH+70+height+35, BW, BH);
label.text=@"label";
label.textAlignment=NSTextAlignmentCenter;
label.adjustsFontSizeToFitWidth=YES;
label.numberOfLines=1;
bt.layer.cornerRadius=2.0;
}else if (i<12){
bt.frame=CGRectMake((self.view.bounds.size.width-4*BW)/5+((self.view.bounds.size.width-4*BW)/5+60)*(i%4),(i/4)*(BH+height)+70, BW, BH);
label.frame=CGRectMake((self.view.bounds.size.width-4*BW)/5+((self.view.bounds.size.width-4*BW)/5+60)*(i%4), (i/4)*(BH+height)+70+35, BW, BH);
label.text=@"label";
label.textAlignment=NSTextAlignmentCenter;
label.adjustsFontSizeToFitWidth=YES;
label.numberOfLines=1;
bt.layer.cornerRadius=2.0;
}
// bt.backgroundColor=[UIColor redColor];
bt.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:[NSString stringWithFormat:@"image%i.jpg",i]]];
[self.view addSubview:bt];
[self.view addSubview:label];
}
现在我们运行看一下结果
