问题 Last week I asked a question about a Simulator bug with NSAttributedString not displaying: iOS 7 Simulator Bug - NSAttributedString does not appear Unfortunately it now appears this is not a simulator bug but an iOS 7 bug. I have now reproduced this issue on an iPhone 5 device. The bug appears to be the combination of using NSUnderlineStyleAttributeName & NSParagraphStyleAttributeName as attributes for a NSAttributedString. I have only tested on two iOS 7 devices so far, and the issue has

问题 Just got stuck with this error while I'm trying to publish an app to app store. Sorry because i cant copy-paste the error code so I will post an image in my question. 回答1: Are you sure the 568h file is actually in PNG format? Also make sure that you provided support for iphone 5 for all your screens? Only adding Default-568h@2x.png is not gaurantee for iphone 5 support. You have to check for framing of all your view for iphone 3.5" and 4" device. You can do the framing by code or autoresizing

问题 Earlier, I was using iOS 6.1 for my project. Recently I have switched to iOS 7. For, a lot of changes I knew, I updated my code.. But I have observed a strange behavior. My view on every screen gets hidden below navigation bar. Repositioning view solves the problem for iOS7, but creates problems for older iOS versions.

问题 I have been searching for an answer to this question in a few hours now, and I just can't figure it out. I want to add a gaussian blur effect to the image when i press the button "Button". The user is the one that is adding the image. I have created an action for the "Button" based on sources from SO and other places on the web. It will not work. What am I doing wrong? Any code would be greatly appreciated. Here is my "Button" action: - (IBAction)test:(id)sender { CIFilter *gaussianBlurFilter

问题 I know that are already some stackoverflow questions that say how to change the status bar for all view controllers. I am currently changing the color of status bar this way: if(IS_IOS7) [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent]; In the application:DidFinishLaunching Additionally, I have changed the value of UIViewControllerBasedStatusBarAppearance in the plist to NO . However, in the splashscreen it stills shows the status bar text with the black

问题 Wanted to find size of a file on some server before downloading it in iOS 7... I have a method of NSURLConnectionDelegate but it is deprecated after iOS 4.3 Here was that method: - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 回答1: You should instead use the NSURLConnectionDataDelegate Note : DATADelegate and its didReceiveResponse: method to send a HEAD request to get just the header: - (void)connection:(NSURLConnection *)connection

问题 I’m fairly sure this is going to be straight forward in that it’s probably not possible. Basically, I’d like to be able to lightly see the background wallpaper through my view in the same way that the new Newsstand app does. I've tried changing the alpha value of the view, and the background color to clear , but neither of these seem to do it. 回答1: Apple has removed the ability to use this api in 7.0.3. What a shame. You certainly can in iOS7, at least as of a few days ago. In our app once

问题 The following code works perfectly from iOS 5 to 6.1. I even have applications in store with that code: -(void)showActivityIndicator { if(!mLoadingView) // { mLoadingView = [[UIAlertView alloc] initWithTitle:@"" message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:nil]; mLoadingView.tag = kAlertViewTag; } [mLoadingView show]; } - (void)willPresentAlertView:(UIAlertView *)alertView { if (alertView.tag == kAlertViewTag) { UIActivityIndicatorView *actInd = [[UIActivityIndicatorView
