Question

Current Code:

- (void)textFieldDidBeginEditing:(UITextField *)textField {
    NSLog(@"begin edit: %@", textField);
}

Related output:

2011-10-30 09:12:08.436 My Project[83470:207] begin edit: <UITextField: 0x6c349d0; frame = (112 2; 182 39); text = 'My Name'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x6c34af0>>

So I know the textfield frame is there, but when I try to grab it:

code:

- (void)textFieldDidBeginEditing:(UITextField *)textField {
    NSLog(@"begin edit: %@", [textField frame]);
    // also tried textField.frame -- same thing
}

error:

Thread 1: EXC_BAD_ACCES (code=1, address=0x42e00000)

output:

(lldb)

I’ve been spinning my wheels on this and I’m not sure where to go next. Thanks for reading my question.

** EDIT – cell xib instantiation (where the textfield lives) **

note: the textfield comes from a xib file that is just a table cell.

static NSString *CellIdentifier = @"ValidatedTextViewTableCell";

ValidatedTextViewTableCell *cell = (ValidatedTextViewTableCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
    [[NSBundle mainBundle] loadNibNamed:@"ValidatedTextViewTableCell" owner:self options:nil];
    cell = validatedTextViewTableCell;
    self.validatedTextViewTableCell = nil;
}

This won’t work:

NSLog(@"begin edit: %@", [textField frame]);

Because frame is a CGRect type, not an object, so the %@ format specifier, which is for objects only, blows up when handed it. You’ll need to log the frame by each of its components, like this:

NSLog(@"begin edit: %f, %f, %fx%f", [textField frame].origin.x [textField frame].origin.y, [textField frame].size.width, [textField frame].size.height);
