iOS创建多个按钮，点击按钮，只改变某一个按钮的状态

一、创建多个按钮

for (int i = 0 ; i < 13; i++){

NSInteger index = i % 3;

NSInteger page = i / 3;

oneButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];

oneButton.frame = CGRectMake(index * (Button_Width + Width_Space), page  * (Button_Height + Height_Space), Button_Width, Button_Height);

[oneButton addTarget:self action:@selector(clickButtonSender:) forControlEvents:UIControlEventTouchUpInside];

//            [oneButton setTitle:self.fenLeiArray[i] forState:UIControlStateNormal];

[oneButton setTitle:@"哈哈" forState:UIControlStateNormal];

[oneButton setTitleColor:LTTextBlackColor forState:UIControlStateNormal];

oneButton.titleLabel.font = LTFont(14);

oneButton.layer.borderWidth = 1;

oneButton.layer.cornerRadius = 3.0f;

oneButton.layer.borderColor = LTTextGrayColor.CGColor;

oneButton.tag = i;

[self.fenLeiArray addObject:oneButton];

[circleFenLeiView addSubview:oneButton];

}

self.circleFenLeiView.height = 200;

fenLeiViewHieht = self.circleFenLeiView.height;

二、点击事件

// 点击按钮选中

-(void)clickButtonSender:(UIButton *)btn{

[self.view endEditing:YES];

NSLog(@"点击了%ld",btn.tag+1);

classifyStr = btn.titleLabel.text;

NSLog(@"=-=-=-=-=-=-=%@",classifyStr);

for (UIButton *button in self.fenLeiArray) {

if (button.tag == btn.tag) {

button.layer.borderColor = LTRedColor.CGColor;

[button setTitleColor:LTRedColor forState:UIControlStateNormal];

}else{

[button setTitleColor:LTTextBlackColor forState:UIControlStateNormal];

button.layer.borderColor = LTTextGrayColor.CGColor;

}

}

}
