问题 So prior to iOS 7.1 I was setting the background image in my app UINavigation Bar via UI Appearance like so. [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"image-name"] forBarMetrics:UIBarMetricsDefault]; It was working fine and the content was getting blurred properly when behind it. Now the content is not blurred at all the navigation bar is just transparent. If I remove the image and set just the navigation bar tintColor it will blur the content correctly. Anyone

问题 I'm getting the above mention error when my client update their device to iOS 7.1, and then try to update our app from the AppCenter. After some searching, i found a post with a similar problem here. But then since i'm in an environment where by the client is using AppCenter to update the apps, i can't be using USB to plugin and install the app for them. Is there any workaround for downloads via AppCenter until a support is released? 回答1: A change was introduced to iOS as of iOS 7.1 that

问题 My app didn't have any crash until iOS 7.1 came out. Now on any removeFromSuperview method, crash. For example: I got view controllers, and when I want to remove a view controller, I remove all of its subviews, and then remove from the stack (stack: I'm storing view controllers in this, for load new contents, and load previous contents): for (UIView *subView in [contentVc subviews]) [subView removeFromSuperview]; And I got -[CALayer retain]: message sent to deallocated instance message

问题 I have an animation thats running fine in iOS 8.1 but in iOS 7.1 the button just appears where it is supposed to be without animation. The button has leading, trailing and bottom constraints of 0, and height constraint of 80. The constraints are setup in the storyboard. In the viewWillAppear method I change the bottom constraint to -80 so it isn't seen in the beginning. When the user presses a button, the button should animate up, I run this method: func animateCtaUp() { self.ctaView

问题 I have a free version of my app and I remove + add autolayout constraints (to hide a premium feature), however if the user purchases my app I'd like to revert back to to the constraints set by interface builder. I'm hoping there's a method which will achieve this, but I haven't been able to find it so far? Here's what I have if (!purchased) { [self.tblOtherAccounts addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[tblOtherAccounts(==0)]" options:0 metrics:nil views

问题 I have some questions about the installation of .ipa file with wireless AdHoc distribution and Enterprise account to be completely clear in my mind (we use XCode 5.1, iOS 7.1) I read (here) that, for adhoc distribution, we don't need an Entreprise account, is that true ? Because I tested the method described in the link but it didn't work. Do we need an Entitlement file anymore ? Is the mobileprovision file already included in the .ipa file generated by XCode 5.1 ? (if we do Product ->

问题 I'm trying to apply a blend filters to 2 images. I've recently updated GPUImage to the last version. To make things simple I've modified the example SimpleImageFilter. Here is the code: UIImage * image1 = [UIImage imageNamed:@"PGSImage_0000.jpg"]; UIImage * image2 = [UIImage imageNamed:@"PGSImage_0001.jpg"]; twoinputFilter = [[GPUImageColorBurnBlendFilter alloc] init]; sourcePicture1 = [[GPUImagePicture alloc] initWithImage:image1 ]; sourcePicture2 = [[GPUImagePicture alloc] initWithImage
