<UIAlertController 이미지>

iOS8부터 alertView가 deprecated되었죠?

우리는 기계적으로 애플의 노예이기 때문에 UIAlertController를 사용해야 합니다.

절이 싫으면 중이 떠나야하는데.. 떠나면 이 추운 날에 굶어야하니까 일단 남아보도록 하죠..

UIAlertController에는 크게 3가지로 나뉩니다.

동영상 한번 보고가실게요. 

그럼 나눠보도록 할게요.

1. No Button, No action.

UIAlertController * alert= [UIAlertController alertControllerWithTitle:@"My Title" message:@"Will dismiss in 2 seconds." preferredStyle:UIAlertControllerStyleAlert]; [self presentViewController:alert animated:YES completion:nil]; dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{ [alert dismissViewControllerAnimated:YES completion:nil]; });

2. 많이 보시던 일반적인 스타일

UIAlertController * alert= [UIAlertController alertControllerWithTitle:@"Yes or No?" message:@"결심했어!" preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) { [alert dismissViewControllerAnimated:YES completion:nil]; }]; UIAlertAction* cancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) { [alert dismissViewControllerAnimated:YES completion:nil]; }]; [alert addAction:ok]; [alert addAction:cancel]; [self presentViewController:alert animated:YES completion:nil];

3. Alert가 화면 아랫부분에 노출

UIAlertController * view= [UIAlertController alertControllerWithTitle:@"Yes or No?" message:@"결심했어!" preferredStyle:UIAlertControllerStyleActionSheet]; UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) { //Do some thing here [view dismissViewControllerAnimated:YES completion:nil]; }]; UIAlertAction* cancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) { [view dismissViewControllerAnimated:YES completion:nil]; }]; [view addAction:ok]; [view addAction:cancel]; [self presentViewController:view animated:YES completion:nil];

4. TextField를 갖는 AlertController

UIAlertController * alert= [UIAlertController alertControllerWithTitle:@"Login" message:@"Enter User Info" preferredStyle:UIAlertControllerStyleAlert]; UIAlertAction* ok = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) { //Do Some action here }]; UIAlertAction* cancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) { [alert dismissViewControllerAnimated:YES completion:nil]; }]; [alert addAction:ok]; [alert addAction:cancel]; [alert addTextFieldWithConfigurationHandler:^(UITextField *textField) { textField.placeholder = @"Username"; }]; [alert addTextFieldWithConfigurationHandler:^(UITextField *textField) { textField.placeholder = @"Password"; textField.secureTextEntry = YES; }]; [self presentViewController:alert animated:YES completion:nil];
