uialertview

问题 I am writing an iOS app, and I have to display a UIAlertView with a spinner. Sometimes , something goes wrong when I try to add the spinner in the center of the alert, usually when there was another alert right before this one (not exactly a rule, but this is how I noticed it fails). I partly solved this bug by delaying the creation of the spinner. Here is how I do it ( alert is a member UIAlertView) : This code is in viewDidLoad : alert = [[[UIAlertView alloc] initWithTitle:@"Loading..."

问题 I want to check if the running code is unit tese case or not execute different code for the result such as: if ( unit test case is running ) { do something } else { do other thing } any idea on this? 回答1: This is a bad approach you should try to simulate logic parts which you are trying to avoid by this statemetn through Mock ojects or other mechanism. Now to your question you can use a oolean variable like isUnittest which you set on test setup and Teardown, ut as saied i dont recommend you

问题 Is there a way for me to get a reference to the button frames in an alertView I created? I'd like to find the position of the top button so I can use its frame to position an image directly above it. I have a couple of extra \n's at the end of my alertview text to make sure there is room to place the image, but I need to determine where that free space is in the alertview. Using the top button as a reference seems like a reliable way to find it. I have tried the following, which does return

问题 The issue only can be reproduced in iOS 7. In the delegate function: - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex , if a UIAlertView is created, the alert view cannot auto rotate. Here is the sample code: - (IBAction)buttonTapped:(id)sender { UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"action sheet" delegate:self cancelButtonTitle:@"cancel" destructiveButtonTitle:@"ok" otherButtonTitles:nil]; [actionSheet showInView:self

问题 In my swift app I have a UIViewController with a single button. This button invokes a function that calls a popup that disappears after 3 seconds. Also, after that time it prints a message to the console. The code of this function is as follows: func showAlertMsg(title: String, message: String){ let alertController = UIAlertController(title: title, message: message, preferredStyle: .Alert) self.presentViewController(alertController, animated: true, completion: nil) let delay = 3.0 * Double
