Passing text value from one view to another
I have this in my table view controller, and i want to pass the cell's text value to my UITextField on the modal view.
- (void)buttonTapped:(id)sender {
AddName *addName = [[AddName alloc] init];
UITableViewCell *cell = (UITableViewCell*)[sender superview];
NSLog(@"text in buttontapped: %@", cell.textLabel.text);
addName.nameField.text = cell.textLabel.text;
addName.delegate = self;
[self presentModalViewController:addName animated:YES];
}
The NSLog shows the correct cell text value.
On my modal view's viewDidLoad method i have this... and the text value never gets set...
- (void)viewDidLoad {
[super viewDidLoad];
开发者_StackOverflow社区 NSLog(@"text: %@",nameField.text);
nameField.autocapitalizationType = UITextAutocapitalizationTypeWords;
nameField.autocorrectionType = UITextAutocorrectionTypeDefault;
[nameField becomeFirstResponder];
}
What's going on?
Thanks.
It looks as though you're assuming that the modal view controller has already loaded its view, since I'm assuming nameField
is a subview. But clearly at the point that your code is trying to set its text
property, the text field and its parent view haven't been loaded yet, so you're sending a -setText:
message to nil
.
Instead, add a property to your modal view controller of type NSString *
, and set that in your buttonTapped
implementation. Then, in the modal view controller's -viewWillAppear
method, you can take the value from the property and put it into the text field.
