EXC BAD ACCESS from UITextField with spaces in it

[Yko]

Hey guys,

I noticed something interesting.

I have an Item class and one of its parameters is

NSString *name;

In a UITextField, I have this code:

- (BOOL)textFieldShouldReturnUITextField *)textField
{
// name is defined in .h as NSString *name;
[nameTF resignFirstResponder];
name = nameTF.text;
NSLog(@"name from UITextField is %@", name);
return YES;
}

then later on,

-(IBAction)donePressed
{
[newItem setName:name];
[newItem setQuantity:quantity];
[newItem setStatus:status];

// pop the view from the Navigation stack
[[self navigationController] popViewControllerAnimated:TRUE];
}

Now, in the UITextField, if I type item1, it works. However, when I type item 1 with a space between item and 1, it gives EXC BAD ACCESS error.

I'm a little stumped because I thought it's a string and spaces are allowed. Any ideas?

Thanks!

name = nameTF.text;

This is wrong. You need to do some research on memory management and properties in objective c.

OK. I changed it to

name = [NSString stringWithString:[name text]];

Still, doesn't work.

of course not

try something else

I like the game slicks playing haha. Look at Slick's guide to properties on this forum to help you out. And also in the delegate method why don't you just use the textfield object that it passes to you instead of nameTF? Its better programming practice. Just a thought...

OK. Let's see if I got this right. I changed it to:

- (BOOL)textFieldShouldReturnUITextField *)textField
{
[textField resignFirstResponder];
[self setName:[textField text]];
NSLog(@"name from UITextField is %@", name);
return YES;
}

I reread Rames44 on the tutorial section of the forums. I read it twice before but keep forgetting. Orginally, I keep trying [name setText:@"string"] because I though that "name" is a string object and I can get/set as long as I synthesize.

Let me know if I'm still wrong. Thanks smith and kapps, really appreciate it. Still learning.

One other question. If I have multiple UITextField and I use [textField resignFirstResponder] does it always assign the keyboard/UITextField as the first responder and knows how to resign it?

Thanks.
