uiswitch

问题 I have a UISwitch inside a custom UITableViewCell (the subclass of which I call RootLabeledSwitchTableCell ). The cell contains a UILabel and UISwitch next to each other. I have a @property called keychainSwitch that points to the switch inside this custom cell: @interface RootLabeledSwitchTableCell : UITableViewCell { IBOutlet UILabel *textLabel; IBOutlet UISwitch *labeledSwitch; } @property (nonatomic, retain) IBOutlet UILabel *textLabel; @property (nonatomic, retain) IBOutlet UISwitch

问题 How can I embed a UISwitch programmatically in a tableView cell in Swift?

问题 In iOS 7 switches don't allow custom on/off images by default. While I can still set them in the Interface Builder it doesn't show up. https://developer.apple.com/library/ios/documentation/userexperience/conceptual/TransitionGuide/TransitionGuide.pdf The transition guide merely notes that it isn't on by default anymore. Presumably there is a way to change that so I do use the images I have. 回答1: Can you use a UIButton instead, using the "selected" state to mean "on"? 回答2: Apple never let this

问题 Is there either a way to implement UISwitch with custom graphics for the switch-states? Or as an alternative the other way round, an UIButton with UISwitch functionality? 回答1: UIButton already supports a "switch" functionality. Just set a different image in Interface Builder for the "Selected State Configuration", and use the selected property of UIButton to toggle its state. 回答2: set the image to show on selected state: [button setImage:[UIImage imageNamed:@"btn_graphics"] forState

问题 This is a repost of my question before but because of too many edit's and I've simplified my examples, I thought it would be more clear if I create a new question instead of re-edit the questions multiple times. PROBLEM: UISwitch object somehow doesn't deallocate even when nothing has been done with it. PROJECT: There are only two view controllers. VC1 and VC2. VC1 has one button to present VC2. VC2 contains one button to dismiss itself and a property of a custom UISwitch , UILabel and a

问题 For the iPhone, I havent been able to find anything like a radio button that triggers the other buttons in a group. So what would everyone suggest using? UISwitch I guess and do something to trigger the others in the group when an other is selected? If I had several UISwitch objects how would I trigger the others to be the opposite of what I switched? 回答1: I also used a custom UISegmentedControl. Something like this: NSMutableArray* buttons; - (void)touchDownAction:(UIButton*)button { [self

问题 UISwitch text shows ON/OFF in English. When I switch language to Japanese, UISwitch shows localized version for ON/OFF text. But, when I switch language to German, UISwitch shows I/O symbols instead of German-localized ON/OFF text. Why is not the behavior consistent across all non-English languages? Is this a bug? Please let me know if you have any info on this. Thanks. 回答1: I think the problem is that in some languages these words are just to big to fit into the button. This has also to do

问题 I have a UISwitch in my view and everything works fine for iOS 7 both on my device and the simulator, but when I run my application in the iOS 6 simulator I get a weird exception. The exception breakpoint fires at this particular line of code: self.mySwitch = [[UISwitch alloc] init]; with the following output: -[__NSCFString count]: unrecognized selector sent to instance Is this somehow a bug in the simulator? I have no idea how to fix this and at the moment I don’t have an iOS 6 device at

问题 I have an app that needs part of the interface to be generated dynamically. Via an API response, I get a JSON representation, containing an ID and label, for each item I need to create. Over a couple of steps, I convert the JSON to arrays and save the values to a plist. Next step is to build the interface from the saved values. This all works as planned. I can dynamically generate the interface elements and they actually show up on the screen where they are supposed to! The problem I am

问题 I have a custom switch. I want the text (on/off) to be in the track and not in the thumb. I was thinking of setting a selector with text in drawable and setting it as track of the switch. But I cannot set text in a shape. Any ideas how I can do this? I also want to add some padding to the track, I dont want the thumb to touch the track. This is kind of how I want it to look: This is the shape of my track: <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape=
