关于UIAlertController的基本使用:
UIAlertControlle 弹出样式:
UIAlertControllerStyleAlert 在屏幕中间
UIAlertControllerStyleActionSheet 在屏幕底部
<pre>
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"标题" message:@"内容" preferredStyle:UIAlertControllerStyleAlert];
<code>UIAlertAction 按钮样式:
UIAlertActionStyleDefault,
UIAlertActionStyleCancel,
UIAlertActionStyleDestructive
<pre>UIAlertAction **default = [UIAlertAction actionWithTitle:@"Default" style:UIAlertActionStyleDefault
handler:^(UIAlertAction * _Nonnull action) { NSLog(@"回调"); }];
UIAlertAction *Destructive = [UIAlertAction actionWithTitle:@"Destructive" style:UIAlertActionStyleDestructive handler:nil];
UIAlertAction *Cancel = [UIAlertAction actionWithTitle:@"Destructive" style:UIAlertActionStyleCancel handler:nil]; <code>
-
添加UIAlertAction:
<pre>
[alert addAction:Default];
[alert addAction:Destructive];
[alert addAction:Cancel];// 添加TextField
[alert addTextFieldWithConfigurationHandler:^(UITextField * _Nonnull textField) {
}];
// 显示
[self presentViewController:alert animated:YES completion:nil];
<code>
