}
Please help me to do this , 请帮助我做到这一点,
You should not handle the cancel button press. 您不应处理取消按钮的按下。
Since all button presses on UIActionSheet
are handled by actionSheet:clickedButtonAtIndex:
you will need to check if the button index is that of the cancel button. 由于
UIActionSheet
上的所有按钮按下都是由actionSheet:clickedButtonAtIndex:
处理的, actionSheet:clickedButtonAtIndex:
您需要检查按钮索引是否为取消按钮的索引。 You can do this with the cancelButtonIndex
on UIActionSheet
: 您可以使用
UIActionSheet
上的cancelButtonIndex
来做到这一点:
- (void) actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
if (actionSheet.cancelButtonIndex == buttonIndex) {
return;
}
}
You can try this 你可以试试这个
- (IBAction)actionSheetCall:(id)sender {
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Confirm call"
message:@"Are you sure to call?"
preferredStyle:UIAlertControllerStyleActionSheet]; // 1
UIAlertAction *secondAction = [UIAlertAction actionWithTitle:@"Cancel"
style:UIAlertActionStyleCancel handler:^(UIAlertAction * action) {
NSLog(@"You pressed cancel button ");
}]; // 3
for(int i = 0; i < [Arr_phone count]; i++) {
UIAlertAction *firstAction = [UIAlertAction actionWithTitle:[activity.Arr_phone objectAtIndex:i]
style:UIAlertActionStyleDefault handler:^(UIAlertAction * action) {
NSLog(@"You pressed Logout one");
//[self setupCall];
[self incomingCall:[Arr_phone objectAtIndex:i]];
}]; // 2
[alert addAction:firstAction]; // 4
}
[alert addAction:secondAction]; // 5
[self presentViewController:alert animated:YES completion:nil]; // 6
}
