Why is cursor not at top of UITextField? - ios

Question

I have an iPad app (XCode5, ARC, Storyboards, iOS 7). This is the problem (placeholder and cursor in middle of UITextField):
This is the code that creates it:
- (IBAction)bSendFeedback:(UIButton *)sender {
// make the popover
UIViewController* popoverContent = [[UIViewController alloc] init];
UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 450, 500)];
popoverView.backgroundColor = [UIColor colorWithWhite:(CGFloat)1.0 alpha:(CGFloat)1.0]; // frame color?
popoverContent.view = popoverView;
//resize the popover view shown in the current view to the view's size
popoverContent.contentSizeForViewInPopover = CGSizeMake(450, 500);
// add the UITextfield to the popover
UITextField *tf = [[UITextField alloc]initWithFrame:CGRectMake(0, 0, 450, 500)];
[tf becomeFirstResponder];
tf.delegate = self;
tf.tag = kSendFeedback;
tf.placeholder = #" Enter your comments here";
tf.backgroundColor = UIColorFromRGB(0xFFFFE0);
tf.returnKeyType = UIReturnKeyDone; // make return key read "Done"
[popoverView addSubview:tf];
// if previous popoverController is still visible... dismiss it
if ([popoverController isPopoverVisible]) {
[popoverController dismissPopoverAnimated:YES];
}
//create a popover controller
popoverController = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
[popoverController presentPopoverFromRect:((UIButton *)oSendFeedback).frame inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
The image is from running under iOS7; it works fine when running under iOS 6.
As you can see, it kind of works but the cursor/placeholder should be at the top of the UITextField... any ideas why it's not there when running under ios&?

Answer 1

It appears that Apple has changed the default vertical alignment of a UITextField to center (UIControlContentVerticalAlignmentCenter) in iOS 7 versus top (UIControlContentVerticalAlignmentTop) in iOS 6 & previous version.
To fix it in all versions, please add this line -
tf.contentVerticalAlignment = UIControlContentVerticalAlignmentTop;
This will put the cursor and placeholder text at the top. Good catch !!
