iOS Help with UITextField plz

[mandude]

k so i have a UITextField just chilling here. now i want it to be that if the user types in a single word or phrase, and pressed the done key, then a UILabel will appear. heres what i have so far but its not working so good:


h file:

@interface........ {
UITextField *textField;
UILabel *label;
}
@property (nonatomic, retain) IBOutlet UILabel *label;
@property (nonatomic, retain) IBOutlet UITextField *textField;
-(IBAction)textFieldDoneEditing:(id)sender;
@end

m. file:

@synthesize textField;
@synthesize label;


-(IBAction)textFieldDoneEditing:(id)sender {
[sender resignFirstResponder];
if (textField.text == @"Hello There") {
label.hidden = NO;
}
}

........

Isn't it

[label setHidden:(NO)];

...but its not working so good

Please elaborate. Vague descriptions of issues aren't going to provide enough basis to make a diagnosis.

Isn't it

[label setHidden:(NO)];

Either'll work. label.hidden takes advantage of Objective-C 2.0's dot notation ability.

P.S. What's with the extraneous parentheses around NO?

 

[MythicFrost]

Oh I see, and I put them there because that's what shows up in XCODE when it shows me what to type, and I like them lol.

You can't compare strings like this

if (textField.text == @"Hello There")

you need to do it this way

if ([textField.text isEqualToString:@"Hello There"])

Using == compares the pointers for equality and doesn't compare the contents of the strings.

Also, I'm not clear how this action method is supposed to be called. First, is it called? Why aren't you implementing the UITextFieldDelegate protocol?

...because that's what shows up in XCODE when it shows me what to type...

Explain further. Are you referring to Code Sense?

Uhhm, probably, the pretty light blue circular text bubbles that I can tab along with that tell me what to type

You're expected to replace the entire bubble with a value. So (BOOL) would be replaced with NO (or YES). The reason for the parentheses is that is how Objective-C refers to the datatype, as in (BOOL) or (id) or (UILabel *).

Alright, good to know, thanks. I'm still torn though, I like the look of the parentheses

 

[dejo]

I'm still torn though, I like the look of the parentheses

If you like the look, go ahead and leave them; they don't really hurt anything. Just realize that they will probably cause confusion if most anybody else looks at your code, since they are not used in the average coding style.

Alright, thanks.

Well, we can't really help you get it working if we don't have answers to the questions we've asked you. In other words, before we can help you, you need to help us.
