iOS: Appending an uneditable string to the end of a UITextView

由 家住魔仙堡 提交于 2019-12-06 14:07:35
I would like to reproduce a screen similar to the Facebook "Update Status" view in iOS. (This text should be editable) Walking (Anything past here should not be editable) - at South Narrabeen Beach The user should be able to enter/edit text to the left of the appended string. The appended string will need to wrap within its parent and be clickable. Does anyone know how this is done? (I have recently seen it in the Viddy app as well). Could it be a growing UITextField with a UIAttributedString split over 2 lines that updates its frame as the text is entered? Update: It looks like what you want

问题 Using iOS6: I would like to retrieve the text entered by a user into a UITextField associated with the UIAlertView. I am aware that I could achieve the desired result with a delegate however I am curious about solving this issue with a callback function as I believe this may be an interesting pattern. I began by examining a common pattern for category extension of the UIAlertView class. Code below. Thanks in advance for any suggestions. import <UIKit/UIKit.h> @interface UIAlertView (Block) -

问题 The label (bottom of the picture) and the text field (top) have the same same attributedText. But look at the underlines. The ones in the text field are only one pixel high. This looks terrible. Does anyone know what is causing this or how to prevent it? - (id)initWithFrame:(CGRect)frame { self = [super initWithFrame:frame]; if (self) { UITextField* textField = [[UITextField alloc]initWithFrame:CGRectMake(100, 100, 600, 200)]; NSMutableAttributedString* string = [[NSMutableAttributedString

How can I draw Rounded Rectangles around my textfields and buttons like Foursquare app

由 我们两清 提交于 2019-12-06 12:10:25
How can I draw a background behind all my buttons and textfields like on the Foursquare iPhone app? See where it says "Share with..." You can achieve rounded corners on any view by changing the cornerRadius property of the view's backing CALayer. To access these properties, you will have to link against the QuartzCore framework. Then you can change the corner radius like this: textFieldBackgroundView.layer.cornerRadius = 10; Just make sure to add <QuartzCore/QuartzCore.h> to your project and #import it. 来源： https://stackoverflow.com/questions/5138996/how-can-i-draw-rounded-rectangles-around-my
