ios7

问题 I know that iOS 4 and 5 do not allow the access of a user's phone number since its outside the sandbox of an application (if it needs to be accepted by apple). I would like to know whether this has changed in iOS 7 - with permissions whether it can be accessed etc. Thanks in advance. 回答1: No. Apple APIs do not provide access to this information. What's more, attempting to get this information without asking the user is generally considered a huge breach of privacy. 回答2: "For security reasons,

问题 I'm trying to move storyboard items in my viewcontroller layout, but the when ran in the simulator, they won't budge. It seems that they are sticking to the orange dotted lines above where I placed them. What are those orange lines and why can't I move my items? Here's what it looks like in the simulator: 回答1: Those orange dotted lines show that the frames of the views don't match their constraints. In this example, I placed a label, pinned it's leading and top space, then moved the label.

问题 I am trying to display some attributed text in a UITextView by using NSTextContainer and NSTextStorage but I don't see anything drawn in the textview (textview itself is drawn with white background as desired but no attributed text in it) I however, can do it by just setting the .attributedText property of UITextView to my attributed text string but I want to know what I am doing wrong here or what concepts I misunderstood. Hopefully someone can explain. - (void) test { UIView *mainView = [

问题 Is there a way to make a method wait for a SpriteKit action initiated within the method to complete before continuing code execution? Here's what I have so far, but it just hangs at the wait loop. __block BOOL wait = YES; SKAction* move = [SKAction moveTo:destination duration:realMoveDuration]; SKAction* sequence = [SKAction sequence:@[[SKAction waitForDuration:0.07],move,[SKAction waitForDuration:0.07] ]]; [spellEffect runAction:sequence completion:^{ [spellEffect removeFromParent]; wait =

问题 I would like to animate dropping an object using the UIDynamicAnimator and gravity/collision/elasticity effects. I looked at Apple's sample app DynamicsCatalog, and it is quite straight forward, except for when the object starts off from the outside the bounds of its container. For example, this is the code taken from the sample app's APLCollisionGravityViewController.m file: UIDynamicAnimator *animator = [[UIDynamicAnimator alloc] initWithReferenceView:self.view]; UIGravityBehavior

问题 when the uitableviewcell is set to style UITableViewCellStyleValue1, and both the delete button and reorder control are shown, the reorder control seems to overlap the text in the detailtextlabel, is there any way to make the reorder control not overlap the detailtextlabel without using custom uitableviewcell? 回答1: I have just hit the same problem and it's causing me a lot of grief! From what I've seen, this seems to be a problem on iOS7 UITableViews when the TableView style is set to

问题 I'm currently trying to build my own Custom ContainerViewController. I'm quite familiar with the iOS ViewController containment API (introduced in iOS 5) and the new iOS7 ViewController Transition API. While implementing my container, i tried to utilize the same patterns UINavigationController and UITabBarController are using. My Container is working well so far and using animated and interactive transitions properly. The Problem is, i packed a huge amount of the logic into my

问题 We have a VOIP application, that records and plays audio. As such, we are using PlayAndRecord (kAudioSessionCategory_PlayAndRecord) audio session category. So far, we have used it successfully with iPhone 4/4s/5 with both iOS 6 and iOS 7 where call audio and tones played clearly and were audible. However, with iPhone 5s, we observed that both the call audio and tones sound robotic/garbled in speaker mode. When using earpiece/bluetooth/headset, sound is clear and audible. iOS Version used with

问题 I'm planning to make an app for ios7, and have an issue with the administrativeArea Placemark Attribute. For iOS6 i get the full name of the administrative area (ex. "California"), but for the iOS7, I get the value of "CA". This is a problem when its so varying. Is there any way I can control this input so its more consistent? The apple docs doesnt eigher explain this in details.. http://developer.apple.com/library/mac/documentation/CoreLocation/Reference/CLPlacemark_class/Reference/Reference
