//遍历button改标题- (void)changeName:(UIButton *)btn{ for
(NSInteger
i = 0; i < 10; i ++) { if
(btn.tag == 10) { [btn setTitle:@"我的名字不一样"
forState:UIControlStateNormal]; }else{ [btn setTitle:@"一样的"
forState:UIControlStateNormal]; } }} |
3.关于UIButton，既可以采用setBackgroundImage来设置底部图片，同时也可以采用 setImage方法；
两者还是有一定区别的；
首先setBackgroundImage，image会随着button的大小而改变，图片自动会拉伸来适应button的大小，这个时候当然可以设置button的title，image不会挡住title；
相反的的setImage，图片不会进行拉伸，原比例的显示在button上，此时再设置title，title将无法显示，因此可以根据需求选中方法；

//初始设置：UIImage *bgImg1 = [UIImage imageNamed:@"Selected.png"];UIImage *bgImg2 = [UIImage imageNamed:@"Unselected.png"];[btn setImage:bgImg2 forState:UIControlStateNormal];[btn setImage:bgImg1 forState:UIControlStateSelected];//然后在button的Action方法改变button状态：- (IBAction) buttonTouch:(id)sender{ UIButton *button = (UIButton *)sender; button.selected = !button.selected;} |
一个uiview上多个button，如何判断是哪个按钮被点击了
UIButton
*button = (UIButton *)sender;
1.根据button.tag来区分
2.或者根据button的title
/****************Label****************************/
label中显示不同颜色的字以及不同字体，字体高亮，Diy label
http://www.cocoachina.com/bbs/read.php?tid=69385&keyword=label
1.core text 2.用NSAttributedString ,...setAttributedText:
给UILabel的文本添加阴影效果
Lable.shadowColor
= color;
Lable.shadowOffset = CGSizeMake(0,
-1.0);
下拉框的实现 UITableView + UIButton + UILabel
http://www.cocoachina.com/bbs/read.php?tid=110202&keyword=label
UIlabel旋转90度
lb.transform=CGAffineTransformMakeRotation(M_PI/2);
button取标题值赋值给label
label.text = button.currenTitle
-（IBAction）buttonClicked：（id）sender{
UIButton
*button =
（UIButton*）sender; //得到你点击的button
NSString
*buttonTitle =
button.titleLabel.text; //得到button的title并赋值给string类型的buttonTitle
(比如你的label名字就叫label的话)
label.text
= buttonTitle; //给label赋值
}
