记录下UIButton的图文妙用和子控件的优先显示
UIButton的用处特别多，这里只记录下把按钮应用在图文显示的场景，和需要把图片作为按钮的背景图片显示场景；
另外记录下在父控件的子控件优先显示方法（控件置于最前面和置于最后面）。
先上效果图：
1、当在某个地方既需要显示图片，还需要显示文字，另外还要有点击功能的时候，这时按钮是个很好的选择。
按钮中的图片和文字的距离可以自由调整，图片的也可以上下左右翻转。日常项目中像这些场景都是很容易碰到的。
按钮图文设置、图文位置移动、按钮中图片翻转示例代码：
/** 测试图文并茂的按钮，图文移动 */
- (void)addMoveImgAndTextButton{
//1、创建一个按钮：30x50
UIButton *iconBtn = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[iconBtn setTitle:@"我的好友" forState:UIControlStateNormal];
[iconBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[iconBtn setImage:[UIImage imageNamed:@"pointer"] forState:UIControlStateNormal];
iconBtn.layer.borderColor = [UIColor redColor].CGColor; //边框颜色
iconBtn.layer.borderWidth = ; //边框宽度
iconBtn.titleLabel.backgroundColor = [UIColor greenColor]; //文字颜色
iconBtn.imageView.backgroundColor = [UIColor blackColor]; //图片颜色
[iconBtn addTarget:self action:@selector(clickButton:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:iconBtn];
self.iconBtn = iconBtn; //2、移动iconBtn按钮图片和文字
UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[btn setTitle:@"图右移字左移" forState:UIControlStateNormal];
btn.titleLabel.numberOfLines = ;
[btn setBackgroundColor:[UIColor blackColor]];
[btn addTarget:self action:@selector(changeBtnFrame:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn]; //3、移动iconBtn按钮图片和文字
UIButton *btn2 = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[btn2 setTitle:@"字右移图左移" forState:UIControlStateNormal];
btn2.titleLabel.numberOfLines = ;
[btn2 setBackgroundColor:[UIColor blackColor]];
[btn2 addTarget:self action:@selector(changeBtnFrame2:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:btn2]; //分割线
UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(, , , )];
lineView.backgroundColor = [UIColor grayColor];
[self.view addSubview:lineView];
} /** 点击按钮使图片位置翻转 */
- (void)clickButton:(UIButton *)sender{
sender.imageView.transform = CGAffineTransformRotate(sender.imageView.transform, M_PI);
} /** 移动图片和文字位置 */
- (void)changeBtnFrame:(UIButton *)sender{ UIEdgeInsets edge = self.iconBtn.imageEdgeInsets;
CGFloat changeNum = ;
self.iconBtn.imageEdgeInsets = UIEdgeInsetsMake(, edge.left + changeNum, , -(edge.left + changeNum));
self.iconBtn.titleEdgeInsets = UIEdgeInsetsMake(, -(edge.left + changeNum), , edge.left + changeNum); NSLog(@"edge.left: %f, edge.right: %f", edge.left, edge.right);
} /** 反方向移动图片和文字位置 */
- (void)changeBtnFrame2:(UIButton *)sender{ UIEdgeInsets edge = self.iconBtn.imageEdgeInsets;
CGFloat changeNum = ;
self.iconBtn.imageEdgeInsets = UIEdgeInsetsMake(, edge.left - changeNum, , -(edge.left - changeNum));
self.iconBtn.titleEdgeInsets = UIEdgeInsetsMake(, -(edge.left - changeNum), , edge.left - changeNum); NSLog(@"...edge.left: %f, edge.right: %f", edge.left, edge.right);
}
2、有时候需要给按钮设置背景图片，一般UI给个图片，然后我们自己对图片进行处理，让背景图片自适应按钮展示，矩形圆角。
但是有时候，产品要求显示的按钮左右必须是圆形的，这时候虽然可以让ui切个适配的图片做背景，其实针对如果是背景图片是纯色的话，我们可以利用
控件的layer.masksToBounds， 和layer.cornerRadius属性来让按钮或者其他控件左右两边都是圆形的。
下面写了五个橙色背景的按钮作比较：背景图片和按钮尺寸匹配的、背景图片和按钮尺寸或偏大或偏小的、处理背景图片让背景图片自适应按钮的、不用背景图片使用图层来设置按钮左右圆形的：
/** 测试给按钮设置背景图片 */
- (void)addBackgroundImgButton{
//4、96x25 按钮设置背景图片，颜色rgb(255,145,0)
UIImage *img = [UIImage imageNamed:@"btn_bg"];
UIButton *clickBtn = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[clickBtn setBackgroundImage:img forState:UIControlStateNormal];
[clickBtn setTitle:@"click Me" forState:UIControlStateNormal];
[self.view addSubview:clickBtn]; //4.2 给按钮设置背景图片, 按钮图片不适配
UIButton *clickBtn2 = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[clickBtn2 setBackgroundImage:img forState:UIControlStateNormal];
[clickBtn2 setTitle:@"click Me" forState:UIControlStateNormal];
[self.view addSubview:clickBtn2]; //4.3 给按钮设置背景图片，按钮和图片不适配
UIButton *clickBtn3 = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[clickBtn3 setBackgroundImage:img forState:UIControlStateNormal];
[clickBtn3 setTitle:@"click Me" forState:UIControlStateNormal];
[self.view addSubview:clickBtn3]; //4.4 处理背景图片，让背景图片自适应按钮
NSLog(@"img.size: %@", NSStringFromCGSize(img.size));
UIImage *newImg = [img stretchableImageWithLeftCapWidth:img.size.width/ topCapHeight:img.size.height/];
NSLog(@"newImg.size: %@", NSStringFromCGSize(newImg.size));
UIButton *clickBtn4 = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[clickBtn4 setBackgroundImage:newImg forState:UIControlStateNormal];
[clickBtn4 setTitle:@"click Me" forState:UIControlStateNormal];
[self.view addSubview:clickBtn4]; //4.5 按钮不使用背景图片，设置背景颜色当做有背景图片
UIButton *clickBtn5 = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[clickBtn5 setTitle:@"click Me" forState:UIControlStateNormal];
clickBtn5.layer.masksToBounds = YES;
clickBtn5.layer.cornerRadius = ;
clickBtn5.backgroundColor = [UIColor colorWithRed:/.f green:/.f blue: alpha:];
[self.view addSubview:clickBtn5]; //分割线
UIView *lineView = [[UIView alloc] initWithFrame:CGRectMake(, , , )];
lineView.backgroundColor = [UIColor grayColor];
[self.view addSubview:lineView];
}
3、在有些场景下，需要控制控件的优先显示或者置后显示，需要用到方法
- (void)bringSubviewToFront:(UIView *)view; // 将子控件view显示在父控件的所有子控件的最前面
- (void)sendSubviewToBack:(UIView *)view; //将子控件view显示在父控件的所有子控件的最后面
示例代码：
/** 测试子控件的优先显示（置前和置后） */
- (void)testSubControlShowFront{
//1、红色view
UIView *redView = [[UIView alloc] initWithFrame:CGRectMake(, , , )];
redView.backgroundColor = [UIColor redColor];
redView.tag = ;
[self.view addSubview:redView]; //2、黑色view
UIView *blackView = [[UIView alloc] initWithFrame:CGRectMake(, , , )];
blackView.backgroundColor = [UIColor blackColor];
blackView.tag = ;
[self.view addSubview:blackView]; //3、紫色view
UIView *purpleView = [[UIView alloc] initWithFrame:CGRectMake(, , , )];
purpleView.backgroundColor = [UIColor purpleColor];
purpleView.tag = ;
[self.view addSubview:purpleView]; //添加操作按钮
UIButton *operatorBtn = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[operatorBtn setTitle:@"红色置前" forState:UIControlStateNormal];
operatorBtn.tag = ;
operatorBtn.backgroundColor = [UIColor blackColor];
[operatorBtn addTarget:self action:@selector(changeViewToFrontShow:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:operatorBtn]; UIButton *operatorBtn2 = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[operatorBtn2 setTitle:@"黑色置前" forState:UIControlStateNormal];
operatorBtn2.tag = ;
operatorBtn2.backgroundColor = [UIColor blackColor];
[operatorBtn2 addTarget:self action:@selector(changeViewToFrontShow:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:operatorBtn2]; UIButton *operatorBtn3 = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[operatorBtn3 setTitle:@"紫色置前" forState:UIControlStateNormal];
operatorBtn3.tag = ;
operatorBtn3.backgroundColor = [UIColor blackColor];
[operatorBtn3 addTarget:self action:@selector(changeViewToFrontShow:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:operatorBtn3]; UIButton *operatorBtn4 = [[UIButton alloc] initWithFrame:CGRectMake(, , , )];
[operatorBtn4 setTitle:@"紫色置后" forState:UIControlStateNormal];
operatorBtn4.tag = ;
operatorBtn4.backgroundColor = [UIColor redColor];
[operatorBtn4 addTarget:self action:@selector(changeViewToFrontShow:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:operatorBtn4];
}
/** 操作按钮，切换view置前显示 */
- (void)changeViewToFrontShow:(UIButton *)sender{ if (sender.tag == ){
//红色置前
UIView *redView = [self.view viewWithTag:]; //将子控件redView在父控件view的所有子控件的最前面显示
[self.view bringSubviewToFront:redView];
}
else if (sender.tag == ){
//黑色置前
UIView *blackView = [self.view viewWithTag:]; //获取黑色子控件 //将子控件blackView在父控件view的所有子控件的最前面显示
[self.view bringSubviewToFront:blackView]; }
else if (sender.tag == ){
//紫色置前
UIView *purpleView = [self.view viewWithTag:]; //获取紫色子控件 //将子控件purpleView在父控件view的所有子控件的最前面显示
[self.view bringSubviewToFront:purpleView];
}
else if (sender.tag == ){
//紫色置后
UIView *purpleView = [self.view viewWithTag:]; //获取紫色子控件 //将子控件purpleView在父控件view的所有子控件的最后面显示
[self.view sendSubviewToBack:purpleView];
}
}
