问题 I found a ColorPicker (ILColorPicker) that takes the whole screen on an iPhone. I want to use it in my iPad app (XCode4 using StoryBoards)... it's asking me to "In your view controller's XIB, add a UIView and then set it's class to ILColorPickerView ". I don't want to use the entire scene, just a small part of it... is there another way I can accomplish this? (using Layers, frames, etc)? 回答1: You could programmatically create a popover (UIPopoverViewController), and put the color picker as

问题 Is there an alternative to fsevent or some kind of wrapper for it? I'm trying to monitor a specific folder for changes to files with a certain extension. 回答1: There is UKKQueue, which is a nice wrapper for kernel queue event monitoring - the alternative mentioned in the documentation. 来源： https://stackoverflow.com/questions/7209811/monitoring-a-directory-for-changes-in-osx-without-fsevent

问题 I have just created a new Single View Application on xCode 4.4. And it was created with .storyboards files (instead xib). Then I have added a UIWebView. And now I can't show a keyboard by the code line: [self.window MakeKeyAndVisible]; Because there is no any window on ViewController.m.

Since this is a

I cannot find a action to make a connection so i am wondering there is an alternate method for the same. please let me know. 回答1: As @Disco S2 says, add the instance of MKMapView as a subview to your view. To know where your user tapped on the map, use this method: - (CGPoint)convertCoordinate:(CLLocationCoordinate2D)coordinate toPointToView:(UIView *)view 回答2: Put the mapkit inside a view and listen for touches in that view. There is then a method

问题 I have duplicated my project by copying and pasting the folders. Then inside the project I renamed the project name so it pops a window asking to rename the target. I've done this twice before with no problems, but this time, inside the Products folder the myproject.app file is still the old one. The new one does not appear on my scheme options, so I don't know what else to do. Xcode complains about an icon file that doesn't exist anymore. Is there anyway to fix it; is there some other way to

问题 I'm a beginner in IOS but I need to show a video when the app is launching. Please Can you help me? If is impossible to implement a video on a splash view, there are any idea to create that? Thanks. If I have an orthographic mistake, sorry I come from Spain. ;D 回答1: The "splash" screen can only be an image to be used as a placeholder until your app is able to start up. Even if you found a way to get a video to play, which I don't think is possible, it is against Apple's HIG for how the

问题 I have Xcode 4 and I created an application using the Tab Bar template (and not View based app). There is a UISwitch in each of these tabs and when I change it, a UILabel switches between ON and OFF . Very simple app and no confusion. Xcode 4 creates two tabs for me by default.
