Disappearing UITextField text

由 岁酱吖の 提交于 2019-12-04 03:01:37
问题 The issue I am having is that text in a UITextField disappears every other keyboard tap on iOS. This issue has happened in multiple view controllers, but previously I have been able to resolve the issue by making the textfield taller, giving it more room to draw the text inside. That solution is not working for this particular situation. I am using a custom font for my app, so I have used a subclass of UITextField for the text fields that automatically sets the custom font. I have tried

This question already has an answer here: Disable auto correction of UITextField 6 answers I have a case where autocorrection NEVER makes any sense. It's incredibly annoying. Can I disable it for the UITextField? With Interface Builder you can disable "Correction" in the "Attributes" Tab in Inspector. Programmaticaly you can use UITextField* textfield = [[UITextField alloc] init]; textfield.autocorrectionType = UITextAutocorrectionTypeNo; 来源： https://stackoverflow.com/questions/3802389/how-to-disable-text-autocorrection-for-an-uitextfield-or-keyboard

UITextPosition in UITextField

由 北战南征 提交于 2019-12-04 00:51:53
Is there any way for me to get at a UITextField's current caret position through the text field's UITextRange object? Is the UITextRange returned by UITextField even of any use? The public interface for UITextPosition does not have any visible members. I was facing the same problem last night. It turns out you have to use offsetFromPosition on the UITextField to get the relative position of the "start" of the selected range to work out the position. e.g. // Get the selected text range UITextRange *selectedRange = [self selectedTextRange]; //Calculate the existing position, relative to the

问题 Is there a way to add a cancel button to the keyboard displayed for UITextField ? Looking over the UITextInputTraits Protocol Reference, I could not find anything, including trying out the different keyboard types. 回答1: You can create a input accessory view which can display a UIToolBar Above the keyboard and then add a cancel button to this. Take a look at the documentation link below for the inputAccessoryView property. http://developer.apple.com/library/ios/#documentation/uikit/reference

How can I move the clear button in a UITextField?

由 混江龙づ霸主 提交于 2019-12-04 00:32:15
For some reason, when I add a UITextfield as a subview of the contentview of a tablecell, the clearbutton does not align with the text typed in the field, and appears a bit underneath it. Is there any way I can move the text of the clearbutton to stop this from happening? Thanks for any help, I haven't seen this, and a screen shot would be helpful. But, the quick answer is that you can inspect the subviews array of the UITextField, find the subview that contains the clear button, and adjust its frame.origin. Edit: It seems I've been downvoted for this answer (written in 2010). This is of not

How to set the color of the place holder text for a UITextField while preserving its existing properties?

由 怎甘沉沦 提交于 2019-12-04 00:07:13
I have seen some answers that show how to change the placeHolder text color for UITextField by overriding the drawPlaceholderInRect: method such as this one: iPhone UITextField - Change placeholder text color but that does not maintain the existing attributes such as alignment, font, etc...what is a better way to solve this? Forrest From iOS 6, Without any subclassing, one can accomplish this with a couple lines of code like so: UIColor *color = [UIColor blackColor]; textField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:placeholderText attributes:@
