Best route to fit a UITextField to UITableView cell - ios

Question

I am wondering what is the best way to make a UITextField fit a UITableView cell.
I have used this method before:
#implementation UITextField (custom)
- (CGRect)textRectForBounds:(CGRect)bounds {
return CGRectMake(bounds.origin.x + 0, bounds.origin.y + 10,
bounds.size.width - 30, bounds.size.height - 16);
}
- (CGRect)editingRectForBounds:(CGRect)bounds {
return [self textRectForBounds:bounds];
}
#end
But this causes an issue:
Category is implementing a method which will also be implemented by its primary class
Although I have seen ways to hide these warnings, it feels like this is more of a hack than a correct method.
What is the best way to fit a UItextField to a cell. This is my field:
// Username field
usernameField = [[UITextField alloc] initWithFrame:(CGRectMake(10, 0, 300, 43))];
usernameField.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
It is input into the cell like this:
if (indexPath.row == 0) {
[cell.contentView addSubview:usernameField];
}

I'd suggest doing this by overriding your custom UITableViewCell's layoutSubviews method. Much simpler there imo. Something like:
- (void)layoutSubviews
{
[super layoutSubviews];
float w, h;
w = (int)(self.frame.size.width - 30);
h = (int)(self.frame.size.height - 16);
[self.detailTextLabel setFrame:CGRectMake(0, 10, w, h)];
}
Here's a fragment of the custom cell initialization
#interface MyCustomCell: UITableViewCell {
}
#end
#implementation MyCustomCell
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) {
}
return self;
}
Here's a fragment of where the custom cell would be created:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
MyCustomCell *cell = (MyCustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[MyCustomCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
