ios7

问题 I have been playing around with the new iBeacons in iOS 7. I have one device setup as a beacon, and the other device ranging to detect when I am near, far, immediate, etc. I'd like to know very quickly when I cross between these ranges. Is there any way to adjust the latency? I find that I have to move my device around very slowly or I will not know when I cross these thresholds. 回答1: No, you would not be able to adjust the beacon latency. As Apple says in Region Monitoring Guide: To prevent

问题 I found one that looks like iOS7 bug while popping view controllers(VCs) in UINavigationController with edge swiping. I set up as following VC hierarchy: UINagivationController | --- UIVewControllerR (root) | --- UIViewControllerA | --- UIViewControllerB I tried to pop UIViewControllerB up by edge swiping and popped UIViewControllerA up continuously. It worked well. But, If first swiping action is canceled then retry to pop it up, a bug I found comes out. After popping UIViewControllerA, I

问题 Goal: To animate the change of a cell's height and reposition surrounding cells. Scenario: Some cells in a collection view load remote images. Initially, those cells are sized statically and an activity indicator is shown. After an image is loaded, it is added to its cell and the cell's height is changed to fit the photo. Notes: I am animating the cell's frame change with animateWithDuration . This works fine, except an increased cell size has it overlapping the cells below. I've blindly

问题 I deal with autolayout set up in Interface Builder. I want to not offset views that are pinned to top layout guide when I hide status bar in runtime. I have discovered that myViewController.topLayoutGuide.length changes from 20 to 0 when hiding status bar. How to prevent it? Or (as workaround) how to set up fullscreen view for various window sizes without pin to top layout guide? Some code to describe my situation: Log(@"frame: %@, top: %.0f", NSStringFromCGRect(myViewController.myView.frame)

问题 I have seen this format (Image shown below) of share option in most of the iOS applications that support iOS 7. Is there a default code/framework available to implement this share option as it is shown in the image below? 回答1: What you are looking for is the UIActivityViewController . Since you asked a general question I can't do more than give you a link to the documentation 回答2: In addition to the accepted answer, a small piece of example code - (void)shareText:(NSString *)text andImage:

问题 As you can see, at the bottom of my page remains a white space. Its height is the same of the old status bar that was present in ios6. Do i have to modify css? Because I never fixed an height for my app, worklight has always chosen the right size. EDIT: you have to save the image and open in a desktop with different color to see the white space at the bottom. * * Licensed Materials - Property of IBM * 5725-G92 (C) Copyright IBM Corp. 2011, 2013.
