其他不多说，代码是王道
第一种平常看到可以打电话的那种模式
//preferredStyle： 设置弹窗类型
UIAlertController *alertView = [UIAlertController alertControllerWithTitle:@"天朝帝都" message:@"我是客服" preferredStyle:(UIAlertControllerStyleActionSheet)];
//字体颜色
alertView.view.tintColor = [UIColor redColor];
//style：设置提示弹窗样式
UIAlertAction *select = [UIAlertAction actionWithTitle:@"给我打个电话聊聊" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
NSLog(@"你打电话了");
}];
UIAlertAction *cancel = [UIAlertAction actionWithTitle:@"取消" style:(UIAlertActionStyleCancel) handler:^(UIAlertAction * _Nonnull action) {
NSLog(@"你选择了取消");
}];
UIAlertAction *other = [UIAlertAction actionWithTitle:@"这是什么情况" style:(UIAlertActionStyleDestructive) handler:^(UIAlertAction * _Nonnull action) {
NSLog(@"这是什么情况");
}];
[alertView addAction:select];
[alertView addAction:cancel];
[alertView addAction:other];
[self presentViewController:alertView animated:YES completion:nil];
第二种有输入框的那种模式
需要注意的是，这里只能使用老版的弹窗提示模式，不能使用脚底弹窗
UIAlertController *alertView = [UIAlertController alertControllerWithTitle:@"提示" message:@"就提示一下吧" preferredStyle:(UIAlertControllerStyleAlert)];
[alertView addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
textField.keyboardType = UIKeyboardTypeNumberPad;
textField.placeholder = @"请输入用户名";
}];
[alertView addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
textField.keyboardType = UIKeyboardTypeNumberPad;
textField.placeholder = @"请输入密码";
}];
UIAlertAction *alertText = [UIAlertAction actionWithTitle:@"确定" style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {
//获取第一个输入框
UITextField *textFieldUser = [[alertView textFields] firstObject];
//获取第二个输入框
UITextField *textFieldPassWord = [[alertView textFields] objectAtIndex:1];
if (textFieldUser.text.length == 0) {
//这里加入自己的逻辑
NSLog(@"用户名");
}else if (textFieldPassWord.text.length == 0){
NSLog(@"密码不为空");
}
}];
UIAlertAction *cancleAction = [UIAlertAction actionWithTitle:@"取消" style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {
NSLog(@"点击取消");
}];
[alertView addAction:cancleAction];
[alertView addAction:alertText];
[self presentViewController:alertView animated:YES completion:nil];
第三种弹窗提示模式
UIAlertController *alertView = [UIAlertController alertControllerWithTitle:@"提示" message:@"普通的提示信息" preferredStyle:(UIAlertControllerStyleActionSheet)];
UIAlertAction *showAlert = [UIAlertAction actionWithTitle:@"提示按钮一" style:(UIAlertActionStyleDestructive) handler:^(UIAlertAction * _Nonnull action) {
NSLog(@"你点击了提示按钮");
}];
UIAlertAction *cancelAlert = [UIAlertAction actionWithTitle:@"提示按钮二" style:(UIAlertActionStyleDestructive) handler:^(UIAlertAction * _Nonnull action) {
NSLog(@"你点击了提示按钮二");
}];
[alertView addAction:showAlert];
[alertView addAction:cancelAlert];
[self presentViewController:alertView animated:YES completion:nil];
