iPhone: How to make a tip balloon programmatically?

由 穿精又带淫゛_ 提交于 2019-12-06 15:30:49
Please provide the code to make a tip balloon programmatically, like Grindr has. I want it to be sized automatically, based on the text & font-size. And, I want to be able to change the location of the arrow. If it's on an end, it should be a right triangle. Otherwise, it should be an eqilateral triangle. // AppDelegate.h @interface AppDelegate : NSObject <UIApplicationDelegate> { } @property (nonatomic, retain) UIWindow *window; @end // AppDelegate.m #import "AppDelegate.h" #import "TipBalloon.h" @implementation AppDelegate @synthesize window; #pragma mark NSObject - (void)dealloc { [window

iOS/Objective-C UILabel text kerning

由 岁酱吖の 提交于 2019-12-06 14:51:27
问题 I was in search of how to increase character spacing in UILabel s to make more attractive my UI Design implementations for the Apps I do.

UILabel Not Updating When Returning to UIViewController

由 天涯浪子 提交于 2019-12-06 14:28:22
问题 I have a simple app that has an NSTimer object in the appDelegate to be accessed by all views. The structure of the app is with a UINavigationController. When I fire the NSTimer object, my UILabel is being updated with the correct countdown function, but when I go back to the rootViewController and back to the countdown timer view, my UILabel is being updated with the current countdown time, but no subsequent updates to the UILabel happen. What am I missing? I have done research on making

Multi-colored UILabel text

由 南楼画角 提交于 2019-12-06 14:07:46
Is is possible to create multi-colored text within a UILabel? I.e, if my text was: "The quick brown fox" have the q and b in blue with the rest of the text in black? I get the feeling I'd have to use a UIWebView and render the text in HTML to accomplish this. Thoughts? You are correct that you need to use a UIWebView. Alternatively, you can draw the text yourself into a custom view, but that would probably be a lot more difficult to implement. If you are going to draw it yourself, you'll want to use the drawing methods in NSString UIKit Additions along with the -[UIColor set] method etc.

UITableViewCell reorganize subviews when the 'delete' button appears

由 牧云@^-^@ 提交于 2019-12-06 13:35:43
问题 Does anyone knows any method to resize subviews(I.E. UILabelView) when Delete button appears. There could be two methods: 1.Capture a notification, if there's one, when the button appears in the UITableViewCell 2.Tell the framework re-arange it automatically. 回答1: In your UITableViewCell class's .m file use layoutSubviews. It is called every time the cell is resized, the delete button appears/disappears, and more: - (void) layoutSubviews { [super layoutSubviews]; frame = self.contentView

问题 I have some text in a UILabel . I want to get the text of the first label in a string variable. For example: label.text = @"You make an object by creating an instance of a particular class. You do this by allocating the object and initializing it with acceptable default values. When you allocate an object, you set aside enough memory for the object and set all instance variables to zero. Initialization sets an object’s initial state—that is, its instance variables and properties—to reasonable

iOS/Swift: Can't assign optional String to UILabel text property

由 徘徊边缘 提交于 2019-12-06 10:01:43
问题 UILabel has a text property, which is an optional String, but it seems to be behaving like an implicitly unwrapped optional. Why can't I assign it another optional String? Thanks. @IBOutlet weak var tweetContent: UILabel! ... var unopt: String = "foo" var opt: String? = "bar" var opt2: String? opt2 = opt //Works fine cell.tweetContent.text? = unopt //Works fine cell.tweetContent.text? = opt //Compile error: Value of optional type 'String?' not unwrapped 回答1: You don't need to unwrap text .
