  • Call method with parameters after animation completion

    - by Jean
    I want to call a method with certain parameters once an animation is done. The flow is something like this: -(void) myMethod:(int)val { [self performAnimation]; [self doSomethingElse:val]; // This should be done after animation completion } I presume the 'doSomethingElse' method needs to be called from the method defined in 'setAnimationDidStopSelector' - or is there a way to have the animation block until done? What is the best way to let the method called on 'setAnimationDidStopSelector' know about the method it needs to call and its parameter? Can this be done with selectors? Or is the only way of doing this by storing the methods and its params in class temp variables and access them when needed?

  • How to make UISlider output nice rounded numbers exponentially?

    - by RickiG
    Hi I am implementing a UISlider a user can manipulate to set a distance. I have never used the CocoaTouch UISlider, but have used other frameworks sliders, usually there is a variable for setting the "step" and other "helper" properties. The documentation for the UISlider deals only with a max and min value, and the output is always a 6 decimal float with a linear relation to the position of the "slider nob". I guess I will have to implement the desired functionality step by step. To the user, the min/max values range from 10 m to 999 Km, I am trying to implement this in an exponential way, that will feel natural to the user. I.e. the user experiences a feeling of control over the values, big or small. Also that the "output" has reasonable values. Values like 10m 200m 2.5km 150 km etc. instead of 1.2342356 m or 108.93837756 km. I would like for the step size to increase by 10m for the first 200m, then maybe by 50m up to 500m, then when passing the 1000 m value, it starts to deal with Kilometers, so then it is step size = 1 km up until 50 km, then maybe 25 km steps etc. Any way I go about this I end up doing a lot of rounding and a lot of calculations wrapped in a forrest of if statements and NSString/Number conversions, each time the user moves the slider just a little. I was hoping someone could lend me a bit of inspiration/math help or make me aware of a more lean approach to solving this problem. My last idea is to populate and array with a 100 string values, then have the slider int value correspond to a string, this is not very flexible, but doable. Thank you in advance for any help given:)

  • Animating multiple UIViews at once using CoreAnimation

    - by Thomas
    Hi, I'm using a UIImageView as a background-image and placed multiple UIButtons on it. Now I want to move the UIImageView (with all the buttons on it) out of sight with a smooth animation. I couldn't find a container or grouping element in IB, so is there a way to move all the Views at once? Thank you in advance and sorry for my english!

  • plist vs static array

    - by morticae
    Generally, I use static arrays and dictionaries for containing lookup tables in my classes. However, with the number of classes creeping quickly into the hundreds, I'm hesitant to continue using this pattern. Even if these static collections are initialized lazily, I've essentially got a bounded memory leak going on as someone uses my app. Most of these are arrays of strings so I can convert strings into NSInteger constants that can be used with switch statements, etc. I could just recreate the array/dictionary on every call, but many of these functions are used heavily and/or in tight loops. So I'm trying to come up with a pattern that is both performant and not persistent. If I store the information in a plist, does the iphoneOS do anything intelligent about caching those when loaded? Do you have another method that might be related?

  • CALayers didn't get resized on its UIView's bounds change. Why?

    - by Geri
    I have a UIView which has about 8 different CALayer sublayers added to its layer. If I modify the view's bounds (animated), then the view itself gets shrinked (I checked it with a backgroundColor), but the sublayers' size remains unchanged. How to solve this? I've just started googleing but haven't found any useful. Thanks in advance.

  • Problem with TTWebController… alternative view controller template for UIWebView?

    - by prendio2
    I have a UIWebView with content populated from a Last.fm API call. This content contains links, many of which are handled by parsing info from the URL in: - (BOOL)webView:(UIWebView *)aWbView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType; …and passing that info on to appropraite view controllers. When I cannot handle a URL I would like to push a new view controller on the stack and load the webpage into a UIWebView there. The TTWebController in Three20 looks very promising since it has also implemented a navigation toolbar, loading indicators etc. Somewhat naively perhaps I thought I would be able to use this controller to display web content in my app, without implementing Three20 throughout the app. I followed the instructions on github to add Three20 to my project and added the following code to deal with URLs in shouldStartLoadWithRequest: TTWebController* browser = [[TTWebController alloc]init]; [browser openURL:@"http://three20.info"]; //initially test with this URL [self.navigationController pushViewController:navigator animated:YES]; This crashes my app however with the following notice: *** -[TTNavigator setParentViewController:]: unrecognized selector sent to instance 0x3d5db70 What else do I need to do to implement the TTWebController in my app? Or do you know of an alternative view controller template that I can use instead of the Three20 implementation?

  • Why did instruments report a leak while its ref count did become zero

    - by bromj
    Hello guys, green hand i am. I'm using instruments, and it did a great help to me so far, but I'm confused now 'cause it report a memory leak to me while its leaked block history shows me that the ref count of that memory had finally become 0. What does it mean? It's really embarrassing that I couldn't post a image here... so I have to describe it in text. Hope it would be clear enough for you: Event Type || RefCt || Responsible Library || Responsible Caller Malloc         || 1        || MyWeather              || +[ForecastData parseSingleForecastWithXMLElement:] Autorelease||           || MyWeather              || +[ForecastData parseSingleForecastWithXMLElement:] Retain         || 2        || MyWeather              || +[ForecastData parseWithData:] Release      || 1        || Foundation              || +[NSAutoreleasePool drain:] Retain         || 2        || Foundation              || +[NSThread initWithTarget:selector:object:] Release      || 1        || Foundation              || +[NSString compare:options:] Release      || 0        || MyWeather              || +[RootViewController dealloc] Any help will be appreciated~

  • Limit to area that receives touch events

    - by Typeoneerror
    Is there's a bounding box on an application that receives touch events? I created a few sample round rect buttons and placed them in different places in my view. The ones in the center of the view receive touch events (and show the highlighted blue color) but if I place a button near the edges of the view, only parts of them are clickable in the simulator. Is this because of Apples style guidelines? I placed a button exactly where a UITabNavigationItem would appear and only the bottom half of it is clickable.

  • Can't Reorder a UITableViewCell into _some_ empty sections of a UITableView

    - by Jeremy Lightsmith
    If I have a UITableView in edit mode, w/ reordering turned on, it seems I can't move some (but not all) cells into some (but not all) empty sections. For example, if I have this layout : Section 1 apple banana Section 2 doberman Section 3 Section 4 Then I can move 'doberman' into any slot in section 1 (except after 'banana'), but I can't move it into section 3 or 4 at all. On the other hand, I can move 'apple' & 'banana' into section section 2 (except after 'doberman'), and I CAN move it into section 3, but NOT into section 4. What gives? this seems like buggy behavior. How do people work around it? Is apple aware of this bug?

I have used below code and it works fine but after drawing line straght when i draw another line then first one gets clear if i do not clear that then they join each other. Please suggest some solution.

  • Custom UITableviewcell, CGGradient still shows when cell is selected?

    - by Burnsoft Ltd
    I'm using a custom tableview cell (like Tweetie's fast scrolling) i've added a gradient to the context, which looks really nice, but when I select the cell, the gradient is still visible. I'm not sure how to go about removing the gradient when the cell is selected? any ideas? cheers Nik - (void)drawContentView:(CGRect)r { CGContextRef context = UIGraphicsGetCurrentContext(); UIColor *backgroundColor = [UIColor whiteColor]; UIColor *textColor = [UIColor blackColor]; UIColor *dateColor = [UIColor colorWithRed:77.f/255.f green:103.f/255.f blue:155.f/255.f alpha:1]; if(self.selected) { backgroundColor = [UIColor clearColor]; textColor = [UIColor whiteColor]; } [backgroundColor set]; CGContextFillRect(context, r); //add gradient CGGradientRef myGradient; CGColorSpaceRef myColorspace; size_t num_locations = 2; CGFloat locations[2] = {0.0, 1.0}; CGFloat components[8] = {0.9f, 0.9f, 0.9f, 0.7f, // Bottom Colour: Red, Green, Blue, Alpha. 1.0f, 1.0f, 1.0f, 1.0}; // Top Colour: Red, Green, Blue, Alpha. myColorspace = CGColorSpaceCreateDeviceRGB(); myGradient = CGGradientCreateWithColorComponents (myColorspace, components, locations, num_locations); CGColorSpaceRelease(myColorspace); CGPoint startPoint, endPoint; startPoint.x = 0; startPoint.y = self.frame.size.height; endPoint.x = 0; endPoint.y = self.frame.size.height-15; // just keep the gradient static size, never mind how big the cell is CGContextDrawLinearGradient (context, myGradient, startPoint, endPoint, 0); CGGradientRelease(myGradient); //gradient end //rest of custom drawing goes here.... } Should I be doing something in the if cell selected code?

  • "Don't Allow" in LocationManager keeps logging errors

    - by stephanie.moreau
    I have an app that checked for location. It asks the user to use location and if the user says no on the menu there is an issue when i load the mapview. Once i select the mapView it asks for the user location again. If the user says no again my console keeps displaying errors/warning as well as my NSLog from the "didFailWithError" of my location Manager class. Is there a way of stopping the LocationManage:didFailWithErrors if the user has already said no? I don't think Apple would accept my app if the Log file gets filled up my the LocationManager Here is an example of what gets repeated in the console ERROR,Time,290362745.002,Function,"void CLClientHandleDaemonDataRegistration(__CLClient*, const CLDaemonCommToClientRegistration*, const __CFDictionary*)",server did not accept client registration 1 WARNING,Time,290362745.005,Function,"void CLClientHandleDaemonInvalidation(__CFMessagePort*, void*)",client 1035.0 has been disconnected from daemon 2010-03-15 12:19:05.002 SAQ[1035:207] LocationManager Error Denied by user

    Hi, I have a Patient entity and a List entity. A Patient can belong to several different lists and a list can have several different patients. Say I have a patient who belongs to 3 lists (A, B, C). I want to remove the patient from lists A & B. I do not want to delete lists A & B themselves though obviously. How do I go about doing this?
