问题 as all we know Apple, we always need to change something for each update. Did somebody solve the moving problem for map legal link? I tried many ways to control legal label but, just it can be hidden? what else I can do? thanks in advance 回答1: You need to change bottomLayoutGuide for your UIViewController. Create a class with following code: MapLayoutGuide.h @interface MapLayoutGuide : NSObject <UILayoutSupport> -(id)initWithLength:(CGFloat)length; @end MapLayoutGuide.m #import

问题 I want to decode two Base64 encoded strings and combine them to make one 128 bit string. I am able to decode the Base64 encoded strings. Can some one guide me on how to combine these two decoded strings? This is the code I used for decoding the two encoded strings. NSData *decodedData_contentKey = [[NSData alloc] initWithBase64EncodedString:str_content options:0]; NSString *decodedString_contentKey = [[NSString alloc] initWithData:decodedData_contentKey encoding:NSUTF8StringEncoding]; NSLog(@

问题 This question already has answers here : Take a picture on iPhone without showing controls (2 answers) Closed 5 years ago . I have a requirement whereby a photo needs to be taken from the camera without the user actually seeing it being taken. Is it possible for an iOS application to take a photo without actually opening the photo app? 回答1: From your brief description and constraints, of course it's possible. My assumptions are: That you want to do this from your own app, and not somehow

问题 My top and bottom toolbars are showing as black when in the app they show as light gray. I'm assuming it may have something to do with the default 'translucency checkbox' I found in the .storyboard, attributes inspector of the toolbar? I'm using a UIActivityViewController to shoot this image out in an email. Here's the code for grabbing the screenshot: // Grab a screenshot UIGraphicsBeginImageContext(self.view.bounds.size); [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];

问题 I have a fairly simple UITableView which uses an NSArray of flight bookings, and displays one cell per booking. Recently customers have raised an issue (which I can only very occasionally reproduce) whereby some of the cells are completely hidden. The space for them is there, but there's just a gap where they should be. The table has a header and footer so I can see the gaps (it's not just that there are less elements). Example screenshot here: http://myflightsapp.com/images/missing-cells.png

问题 I have created small app that use this project as it's core: https://github.com/dsdavids/TTLocationHandler And it worked fine until I have moved stating location services from another view in app. What app is doing: When it is started you can tap on START button and ( in emulator locations must be enabled ) on the map route of movement is displayed as you move. The problem came when I moved starting action in a second view. In that second view I just want to start location service and close

问题 In my app, I download a set of point from a web service using json. Actualizing the app to iOS7, I am experimenting that problem: the locations are downloaded but pins on the map are not painted until user touchs and "moves" the map. Then they appear and all work as in iOS6. How can I correct that behavior? EDIT: AddAnnotation is called at the end of a method that receive data, parse the json and pass them to mylocaction object: - (void)plotBarPosition:(NSString *)data_string { // Parse the

问题 To say I'm new to Objective-C would be a huge understatement. I'm primarily a Ruby/Rails developer and it completely spoiled me when it comes to OOP & programming in general. After getting tired of reading tutorials, I decided to try to use NSRULSession to hit one of my Rails apps (an Elder Scrolls Online skill planner) & display some of the JSON response on my iOS app. Delegates make no sense, I'm not sure how to break this functionality up into methods, etc, so I thought I'd keep it simple

问题 This is my object: var charsObj = {"drive":{"status":"inprogress","data":"some data","history":"the text of my history"}} function getNote(x) { if ( x in charsObj) { console.log(charsObj[x]) } else { console.log('nothing', charsObj[x]) } } if I call getNote('drive') it returns my object value as expected EXCEPT iOS returns 'nothing', undefined . How do I get this to work on iOS? 来源： https://stackoverflow.com/questions/26024488/get-object-value-by-property-reference-not-working-on-ios

问题 I'm developing my first universal iOS app with XCode 5.0.2 and iOS 7, and I have some questions on the screen size differences between iPhone and iPad (including Mini). If the app contains UIButton s with custom .png images, do I need to increase the size of the UIButton s along with bigger size images when developing for iPad?. I'm already half done with the iPhone app and not using storyboards but using IB to create NIBs. I tried to use the same iPhone UIButton size on the iPad NIB and it
