  • iPhones SDK: Setting a relationship property object using core data?

    - by Harkonian
    I'm using core data in my app. I have two entities that are related: EntityA and EntityB. EntityA has a property of type "relationship" with EntityB. In addition, both of these entities are defined classes (not the default NSManagedObject). I'm inserting a new object into my data like this: EntityA *newEntityA = [NSEntityDescription insertNewObjectForEntityForName:@"EntityA" inManagedObjectContext:self.managedObjectContext]; newEntityA.name = @"some name"; newEntityA.entityB.name = @"some other name"; The problem is entityB.name is null. Even if I add an NSLog() statement right after assigning the value, it is null. What is the proper way of setting my "name" property of EntityB when EntityB is a property of EntityA?

  • Iphone sdk, How to post data to web server? anybody has example ?

    - by user352385
    Hi, guys, I want to post data to web server, like username and password, on the web server, I used PHP to echo yes or no, I attached all the code. Can anybody help me out, what is wrong with the code. Since it always says incorrect password or username. I tried to test the php code with username and password inside, it is working. So please help me. Thank you.

  • [ipad] Is there a SDK for the photo gallery?

    - by Rafael Steil
    The "Photos.app" in iPad has a gallery that you can browse all photos, including support for slideshow and other things. I'd like to know if this API is available (aka, not private) and which one it is (so I won't need to implement one photo gallery from scratch). I looked at http://github.com/facebook/three20, but I'm not sure if it is the same thing. Thank.

  • iPhone SDK: How to detect a row-hit while in the editing mode?

    - by Carol
    I've looked everywhere and I can't find it. I have a UITableView that contain rows of "checkmark" cells. The user clicks on a row to check/uncheck it. (It works!!!!) But I also want to allow the user to EDIT the data on that row. ... so I have an "EDIT" button at the top. The user hits it and is allowed to DELETE any rows. (That works too!!!!) But how do I also detect a "tap" on that row. Where is there some kind of a didSelectRowAtIndexPathWhileInEditMode ???? (Is that really the best way to do this: Allow "selections", and "deletions", and "editing" of each row?)

  • How to check for local Wi-Fi (not just cellular connection) using iPhone SDK?

    - by Michael
    I'm currently using the following to check whether Wi-Fi is available for my application: #import <SystemConfiguration/SystemConfiguration.h> static inline BOOL addressReachable(const struct sockaddr_in *hostAddress); BOOL localWiFiAvailable() { struct sockaddr_in localWifiAddress; bzero(&localWifiAddress, sizeof(localWifiAddress)); localWifiAddress.sin_len = sizeof(localWifiAddress); localWifiAddress.sin_family = AF_INET; // IN_LINKLOCALNETNUM is defined in <netinet/in.h> as 169.254.0.0 localWifiAddress.sin_addr.s_addr = htonl(IN_LINKLOCALNETNUM); return addressReachable(&localWifiAddress); } static inline BOOL addressReachable(const struct sockaddr_in *hostAddress) { const SCNetworkReachabilityRef target = SCNetworkReachabilityCreateWithAddress(kCFAllocatorDefault, (const struct sockaddr *)hostAddress); if (target != NULL) { SCNetworkReachabilityFlags flags = 0; const BOOL reachable = SCNetworkReachabilityGetFlags(target, &flags); CFRelease(target); return reachable && (flags & kSCNetworkFlagsReachable); } return NO; } This, however, does not return NO as it should when the iPhone is connected only to a cellular network but not a Wi-Fi network. Does anyone know how to fix this? Edit So this is what I ended up using: #import <arpa/inet.h> // For AF_INET, etc. #import <ifaddrs.h> // For getifaddrs() #import <net/if.h> // For IFF_LOOPBACK BOOL localWiFiAvailable() { struct ifaddrs *addresses; struct ifaddrs *cursor; BOOL wiFiAvailable = NO; if (getifaddrs(&addresses) != 0) return NO; cursor = addresses; while (cursor != NULL) { if (cursor -> ifa_addr -> sa_family == AF_INET && !(cursor -> ifa_flags & IFF_LOOPBACK)) // Ignore the loopback address { // Check for WiFi adapter if (strcmp(cursor -> ifa_name, "en0") == 0) { wiFiAvailable = YES; break; } } cursor = cursor -> ifa_next; } freeifaddrs(addresses); return wiFiAvailable; } Thanks "unforgiven" (and Matt Brown apparently).

  • IPhone sdk stop the accelerometer from working when something happens.

    - by Harry
    Hi, I am using the accelerometer to move a few UIImageViews around the screen, at the moment the accelerometer only works when a NSTimer is at 0, this is fine. I would also like to make the accelerometer stop again when a different function happens. here is my code at the moment: -(BOOL) accelerometerWorks { return time == 0; } -(void) accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration{ if(![self accelerometerWorks]) return; valueX = acceleration.x*25.5; int newX = (int)(ball.center.x +valueX); if (newX 320-BALL_RADIUS) newX = 320-BALL_RADIUS; if (newX < 0+BALL_RADIUS) newX = 0+BALL_RADIUS; int XA = (int)(balloonbit1.center.x +valueX); if (XA 320-BALL_RADIUS) XA = 320-BALL_RADIUS; if (XA < 0+BALL_RADIUS) XA = 0+BALL_RADIUS; int XB = (int)(balloonbit2.center.x +valueX); if (XB 320-BALL_RADIUS) XB = 320-BALL_RADIUS; if (XB < 0+BALL_RADIUS) XB = 0+BALL_RADIUS; int XI = (int)(balloonbit3.center.x +valueX); if (XI 320-BALL_RADIUS) XI = 320-BALL_RADIUS; if (XI < 0+BALL_RADIUS) XI = 0+BALL_RADIUS; int XJ = (int)(balloonbit4.center.x +valueX); if (XJ 320-BALL_RADIUS) XJ = 320-BALL_RADIUS; if (XJ < 0+BALL_RADIUS) XJ = 0+BALL_RADIUS; int XE = (int)(balloonbit5.center.x +valueX); if (XE 320-BALL_RADIUS) XE = 320-BALL_RADIUS; if (XE < 0+BALL_RADIUS) XE = 0+BALL_RADIUS; int XF = (int)(balloonbit6.center.x +valueX); if (XF 320-BALL_RADIUS) XF = 320-BALL_RADIUS; if (XF < 0+BALL_RADIUS) XF = 0+BALL_RADIUS; int XH = (int)(balloonbit8.center.x +valueX); if (XH 320-BALL_RADIUS) XH = 320-BALL_RADIUS; if (XH < 0+BALL_RADIUS) XH = 0+BALL_RADIUS; ball.center = CGPointMake (newX, 429); balloonbit1.center = CGPointMake (XA, 429); balloonbit2.center = CGPointMake (XB, 426); balloonbit3.center = CGPointMake (XI, 410); balloonbit4.center = CGPointMake (XJ, 415); balloonbit5.center = CGPointMake (XE, 409); balloonbit6.center = CGPointMake (XF, 427); balloonbit8.center = CGPointMake (XH, 417); } This all works fine, i would now like to stop the accelerometer from working, using the same accelerometerWorks method or a new method, accelerometerWontWork. This is the code that when it is called i would like the accelerometer to stop. (it is very long so i wont put all of it there, but its all the same throughout): -(void) checkCollision{ if (CGRectIntersectsRect(pinend.frame, balloonbit1.frame)){ if (balloonbit1.frame.origin.y pinend.frame.origin.y){ [maintimer invalidate]; levelfailed.center = CGPointMake (160, 235); } } if (CGRectIntersectsRect(pinend.frame, balloonbit2.frame)){ if (balloonbit2.frame.origin.y pinend.frame.origin.y){ [maintimer invalidate]; levelfailed.center = CGPointMake (160, 235); } } if (CGRectIntersectsRect(pinend.frame, balloonbit3.frame)){ if (balloonbit3.frame.origin.y pinend.frame.origin.y){ [maintimer invalidate]; levelfailed.center = CGPointMake (160, 235); } } } I understand that i may have to turn this into a BOOL. Thats fine. If i haven't explained it well please say and i will re write it. Thanks! Harry.

  • Iphone SDK quesiton: How to make a Drawing method in a View class work using CGContextRef?

    - by SimpleCode
    I have these 2 methods in the View class. the drawRect method always gets called when the view is initalized. But i can't get the drawLine method to work. It doesn't do anything when it gets called. Am i supposed to deal with cgimagecontext or something like that? please help!! (void)drawRect:(CGRect)rect { // Drawing code // Drawing code CGContextRef contextRef = UIGraphicsGetCurrentContext(); //CGContextSetRGBFillColor(contextRef, 0, 0, 255, 1); CGContextSetRGBStrokeColor(contextRef, 0, 0, 0, 1); CGContextSetLineWidth(contextRef, 5.0); CGContextBeginPath(contextRef); CGContextMoveToPoint(contextRef, 0, 0); CGContextAddLineToPoint(contextRef, 320, 480); CGContextStrokePath(contextRef); } -(void)drawLine:(CGPoint)from to:(CGPoint) to { // Drawing code CGContextRef contextRef = UIGraphicsGetCurrentContext(); //CGContextSetRGBFillColor(contextRef, 0, 0, 255, 1); CGContextSetRGBStrokeColor(contextRef, 0, 128, 0, 1); CGContextSetLineWidth(contextRef, 5.0); CGContextBeginPath(contextRef); CGContextMoveToPoint(contextRef, 0, 0); CGContextAddLineToPoint(contextRef, 320, 50); CGContextStrokePath(contextRef); }

  • iPhone SDK: Know when tab on Tab Bar is clicked?

    - by Nic Hubbard
    I have a tab bar which displays different views when clicked. When you click a tab for the first time, it calls the viewDidLoad method. But, it only calls that the first time. Is there a method that is called when a user clicks back to that tab, since the viewDidLoad won't be called that second time? (I need to do this to update a UITableView when the user clicks back to a tab)

  • iPhone SDK: Can a UIButton with custom images display the title?

    - by Harkonian
    If I create a custom UIButton with images for UIControlState normal and UIControlStateSelected, am I still supposed to be able to display the title for the button? Currently I can't. This is how I create my button: UIImage *moveButtonImage = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"button_move_inactive" ofType:@"png"] ]; UIImage *moveButtonSelectedImage = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"button_move_pressed" ofType:@"png"] ]; self.moveButton = [UIButton buttonWithType:UIButtonTypeCustom]; [self.moveButton setImage : moveButtonImage forState : UIControlStateNormal]; [self.moveButton setImage : moveButtonSelectedImage forState : UIControlStateSelected]; [self.moveButton setTitle:@"Test" forState:UIControlStateNormal]; The button title never displays in this case and I'm forced to create my own label to display on the button, which seems like a hacky way of doing things. Maybe I'm doing something wrong here?

  • iphone sdk: autorotate jumps back up the page, showing information that has already been read...

    - by jonathan
    Hi, I am using - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation{ return YES; } to allow rotation, which works fine - except that the landscape view jumps backwards up the page that is being displayed. I can't figure out what I should be looking at to fix it. I just want the page to rotate where it is. Any pointers would be great. Am a noob, as is probably clear. Thanks Jonathan

  • Converting image to Black & White image on iPhone SDK issues.

    - by KfirS
    Hello, I've used a familiar code to convert image to Black & White which I've founded on several forums. The code is: CGColorSpaceRef colorSapce = CGColorSpaceCreateDeviceGray(); CGContextRef context = CGBitmapContextCreate(nil, originalImage.size.width, originalImage.size.height, 8, originalImage.size.width, colorSapce, kCGImageAlphaNone); CGContextSetInterpolationQuality(context, kCGInterpolationHigh); CGContextSetShouldAntialias(context, NO); CGContextDrawImage(context, CGRectMake(0, 0, originalImage.size.width, originalImage.size.height), [originalImage CGImage]); CGImageRef bwImage = CGBitmapContextCreateImage(context); CGContextRelease(context); CGColorSpaceRelease(colorSapce); UIImage *resultImage = [UIImage imageWithCGImage:bwImage]; // This is result B/W image. CGImageRelease(bwImage); return resultImage; When I'm using this code with on Horizontal image it's work fine, but when I'm trying a to use this code on Vertical image, the result is disproportionate image and rotate 90 degree left. Can anyone know what could be the problem? Thanks, Kfir.

  • Inserting a string array as a row into an Excel document using the Open XML SDK 2.0

  • How to make RegexKitLite w/ iPhone SDK produce a list of all matches +/- and also return surrounding

    - by Matt
    I'd like to create a regular expression that will match and return based on the following criteria: 1) I have N search terms entered by a user 2) I have a body of text. 3) I want to return a list of all the occurrences of all the search terms entered by the user plus surrounding context. I think (\w+\W+){,4}(", ")(\W+\w+){,4} might work. 4) I don't know how to use RegexKitLite at all. Do I invoke a RegexKitLite class? or does it interface into NSString somehow?

  • iPhone SDK: How to store the time each word was typed?

    - by Harkonian
    My problem is twofold: 1) I'm trying to determine an eloquent way to allow the user to type into a UITextView and store the time each word was typed into an array. The time will be a float which starts at 0 when the user begins to type. 2) Conversely, I'd like the user to be able to tap on a word in the UITextView and display the time that word was typed (displaying in an NSLog() is fine). Considerations that may throw a wrench into a possible approach -- what if the user goes back to the top of the text and starts typing or to the middle of the text? Even a suggested approach without code would be appreciated, because right now I'm drawing a blank.

  • Does iPhone SDK Objective C support functions inside of functions?

    - by Moshe
    I know that javascript, for example supports functions inside of functions, like so: function doSomething(){ function doAnothingThing(){ //this function is redefined every time doSomething() is called and only exists inside doSomething() } //you can also stick it inside of conditions if(yes){ function doSomethingElse(){ //this function only exists if yes is true } } } Does objective-c support this? Theoretical example: -(void) doSomething:(id) sender{ -(void) respondToEvent: (id) sender{ //theoretically? ... please? } } BONUS: What is the proper term for a "local" function?
