隐藏UIAlertView中在客观-c
我有两个方法出现和消失UIAlertView中隐藏UIAlertView中在客观-c
- (void)showAlert {
UIAlertView *myAlert = [[UIAlertView alloc] initWithTitle:@"My Alert"
message:@"Do you want to continue?"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"No", @"Yes", nil];
[myAlert show];
}
// dismiss uialert
-(void)dismiss:(UIAlertView*)alert{
[alert dismissWithClickedButtonIndex:0 animated:YES];
}
我有,当我想打电话给我辞退方法的问题,我不知道该怎么myAlert传递给解除方法以隐藏UIAlertView。
[self dismiss: // how to pas myAlert];
您需要创建全球UIAlertView中对象。
YourController.h
@property (strong, nonatomic) UIAlertView *myAlertView;
YourController.m
-(void)showAlert
{
myAlertView = nil;
myAlertView = [[UIAlertView alloc] initWithTitle:@"My Alert"
message:@"Do you want to continue?"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"No", @"Yes", nil];
[myAlert show];
}
-(void)dismiss
{
[myAlertView dismissWithClickedButtonIndex:0 animated:YES];
}
非常感谢@Nirmalsinh。 – Steven
UIAlertView中不赞成使用UIAlertController:
使用语法如下:
UIAlertController* alert = [UIAlertController
alertControllerWithTitle:@"SUCCESS"
message:@"Profile picture updated successfuly."
//automatically 2 sec alert will disappear preferredStyle:UIAlertControllerStyleAlert];
[self performSelector:@selector(abc:) withObject:alert afterDelay:2];
UIAlertAction* ok = [UIAlertAction
actionWithTitle:@"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
}];
[alert addAction:ok];
[self presentViewController:alert animated:YES completion:nil];
当u要解雇乌尔UIAlertController:
-(void)abc:(UIAlertController*)x{
[x dismissViewControllerAnimated:YES completion:nil];
}
@st即使你不需要创建任何解雇警报的方法。但我想你也检查下面的链接,因为UIAlertview已被弃用,你可以使用UIAlertcontroller而不是它。 链接: UIAlertView first deprecated IOS 9
苹果允许在OS 9之后。所以现在我们可以再次使用它。 – Nirmalsinh
这太棒了! thx @Nirmalsinh来更新我。 –
你想自动解雇alertview没有选择是或否?请简洁明了 – Arun
UIAlertView中已被弃用。请参阅[本答案](http://stackoverflow.com/questions/4463806/adding-a-simple-uialertview/28383410#28383410)了解最新的示例。 – FreeNickname
