In this example we have two UIViews: one backgroundView which does not change, and one numberView which can be moved, for example by a pan gesture (we’re not dealing with that though) Once the user lets go of the movable numberView, we want to reset the view back to the middle, to the same position […]
Table View headers or footers can’t be tapped. Sometimes however that’s exactly what we want to do. In this example we’ll add a new UIView to out table view and add it to the table’s footer. Inside this view we’ll have a custom button which we’ll create with an image. We’ll also have a method […]
Like in Subversion, Git supports tags. Most developers use tags to “freeze” a bunch of files at a moment in time, much like a snapshot. Commonly this feature is used whenever a new release of your software is… well… released. Xcode does not support this feature via the GUI, but of course Git does. Let’s […]
When you deploy an app with Xcode 5 to an iOS 7 device, all UI elements have the new iOS 7 look. This is true even if the app was never made for such snazzy graphics. Sadly, on some occasions, that new look blows up in your face, rendering your “legacy” app useless in iOS […]
Even though Xcode 5 available, I’d still like to use Xcode 4.6.3 at times to submit updates of my “legacy” apps. Xcode 5 ruins certain aspects of my design, plus I’d like to keep the iOS 6 look for now. Xcode 5 uses Asset Catalogues to keep track of images, and there’s seemingly no way […]
I understand there can be many reasons for this error message. Xcode needs a distribution profile with the same Bundle Identifier as the app. Even though this seemed to have worked in the past, Xcode 4.6.3 has gotten more pernickety as of late. Let’s fix this. Provisioning Portal Head over to the Apple Provisioning Portal […]
Since Xcode 5 and iOS 7 the default appearance of a UINavigationBar is black translucent. This even affects the same app running in iOS 6. Black opaque is deprecated and can no longer be set in Interface Builder. However, you can set the appearance for all nav bars by putting this little gem in your […]
Since UIBarButtonItems do not have a “hidden” property, we can’t just set this to yes and it’ll disappear. Instead, we can set them to nil. In this example we’re hiding the right item in the navigation controller: [self.navigationItem setRightBarButtonItems:nil animated:YES];
