UIActivityIndicatorView is not display at the right time
- by Alexandre
I'm making a form that allows the user to enter datas in my IOS application. This form allows the user to enter a lot of repetive datas. So, sometimes, the process takes time and I would like to display a UIActivityIndicatorView during this process.
Unfortunalty the spinner appears only one second or less at the end of the process, not at the beginning as expected.
There is some code :
- (void) manageSpinner{
spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
[spinner setCenter:CGPointMake(self.view.bounds.size.width/2.0, self.view.bounds.size.height/2.0)]; // I do this becau I'm in landscape mode
UIImageView *imageView = [[UIImageView alloc]initWithFrame:self.tableView.bounds];
UIImage *image = [UIImage imageNamed:@"dark_gradiant.jpg"];
[imageView setImage:image];
[imageView addSubview:spinner];
[self.tableView addSubview:imageView];
[spinner startAnimating];
}
//On click save by the user
- (IBAction)save:(id)sender{
//Collect information from the form
myObject.name = nameTF.text;
[...]
if(informations OK[...]){
//Manage spinner
[self manageSpinner];
//Add : this is the long process
for (int i=0; i<nbRepeatChooseByUser; i++) {
[myObject register];
}
//Call the delegate that will dismiss the form
[self.delegate theSaveButtonOnTheAddMyObjectTVCWasTapped:self];
}
}
The spinner is called before the adding method but it seems to be set up after the process.
Thank you,
Alexandre
