uitextfield

问题 Quick question - if a textfield in a webform, does not automatically has the focus set by the form, ie you got to press the field before the keyboard pops up - am I correct to assume that field cannot be edited then? In other words - I cannot set a text for a textField by injecting javascript into it, unless it gets a focus upon loading of the website right? NOTE: I am not talking about set texts or placeholders here:-) Cheers 回答1: Yes you can! You can use Javascript to set the value:

问题 I have several text views in my app. All but one are UITextField, and the other is a UITextView, located right in the middle of the others. This is due to this section needing much more room for the user to type and see all of what they are typing out. I have it set up so that when the user presses next on the keyboard, it goes to the next field, using this code: - (BOOL)textFieldShouldReturn:(UITextField *)textField { if (textField == firstName) { [firstName resignFirstResponder]; [lastName

问题 I have an app built for iOS 5 that I'm trying to upgrade straight to iOS 7, so this also maybe an issue with iOS 6. We have a UITextField inside a custom table view cell (class derived from UITableCellView), but tapping on it no longer brings up the keyboard in the simulator. Everything is enabled, and User Interaction Enabled is checked. It used to work fine in iOS 5.

问题 How do I dismiss a UITextField with keyboard type UIKeyboardTypeNumberPad ? The accepted answer to this question suggests to either add a bar with a dismiss button as an inputAccessoryView or to listen to touch events on the background. I prefer the second approach, i.e. listen to touch events on the view containing the UITextField . However, this approach fails if VoiceOver is active. How do you resignFirstResponder in that situation? 回答1: You need an alternative way to perform the gesture.

Each UITableViewCell has an image for the product and a couple of labels along with the UITextField and an action button. Here is the code for my cell creation: - (UITableViewCell *)tableView:

问题 I've implemented a subclass of UITextField that has padding as follows: methods taken from here - (CGRect)textRectForBounds:(CGRect)bounds { return CGRectInset(bounds, 10, 10); } - (CGRect)editingRectForBounds:(CGRect)bounds { return CGRectInset(bounds, 10, 10); } With a combination of the above, setting the textField as the firstResponder in viewWillAppear: , and having an initial starting value in the field, I've run into an issue where the text is invisible until the field is edited, and
