  • UIButton to intercept UITableView's didSelectRowAtIndexPath method

    - by Michael
    I've got a UIButton on a table cell that is meant to pop up a UIActionSheet but the problem is the didSelectRowAtIndexPath captures that touch and its action takes precedence. Any clever way to override that action when the user touches the button and still have the default action when the user presses elsewhere in the cell? Too bad there is no MoveToFront property.

  • how to extend a protocol for a delegate in objective C, then subclass an object to require a conform

    - by fess .
    I want to subclass UITextView, and send a new message to the delegate. So, I want to extend the delegate protocol, What's the correct way to do this? I started out with this: interface: #import <Foundation/Foundation.h> @class MySubClass; @protocol MySubClassDelegate <UITextViewDelegate> - (void) MySubClassMessage: (MySubClass *) subclass; @end @interface MySubClass : UITextView { } @end implementation: #import "MySubClass.h" @implementation MySubClass - (void) SomeMethod; { if ([self.delegate respondsToSelector: @selector (MySubClassMessage:)]) { [self.delegate MySubClassMessage: self]; } } @end however with that I get the warning: '-MySubClassMessage:' not found in protocol(s). I had one way working where I created my own ivar to store the delegate, then also stored the delegate using [super setDelegate] but that seemed wrong. perhaps it's not. I know I can just pass id's around and get by, but My goal is to make sure that the compiler checks that any delegate supplied to MySubClass conforms to MySubClassDelegate protocol. To further clairfy: @interface MySubClassTester : NSObject { } @implementation MySubClassTester - (void) one { MySubClass *subclass = [[MySubClass alloc] init]; subclass.delegate = self; } @end will produce the warning: class 'MySubClassTester' does not implement the 'UITextViewDelegate' protocol I want it to produce the warning about not implementing 'MySubClassDelegate' protocol instead. Thanks, a bunch. (thanks brad)

  • wheel of fortune collision detection

    - by Andrew
    Hey, I have a wheel segmented into 8 pie pieces, and a picker that is pointing at the currently selected segment (think wheel of fortune). I want to highlight the currently selected segment, and so have started to use Chipmunk to construct the 8 segments, attached to a rotating body, and then the picker that is put in a position to collide with each of the segments. The trick is, how do you allow the picker to pass over top of the segments, while still getting the collision, but not actually colliding and slowing down the wheel? I haven't started down this path yet, but thought this may solve the problem: removing the colliding segment and then putting it back after the picker has started colliding with another segment a bit away (like two segments away). There may be a much simpler solution not even involving Chipmunk that I haven't thought of. Thanks, Andrew

  • UITableView: moving a row into an empty section

    - by Frank C
    I have a UITableView with some empty sections. I'd like the user to be able to move a row into them using the standard edit mode controls. The only way I can do it so far is to have a dummy row in my "empty" sections and try to hide it by using tableView:heightForRowAtIndexPath: to give the dummy row a height of zero. This seems to leave it as a 1-pixel row. I can probably hide this by making a special type of cell that's just filled with [UIColor groupTableViewBackgroundColor], but is there a better way? This is all in the grouped mode of UITableView UPDATE: Looks like moving rows into empty sections IS possible without any tricks, but the "sensitivity" is bad enough that you DO need tricks in order to make it usable for general users (who won't be patient enough to slowly hover the row around the empty section until things click)

  • Core Plot never stops asking for data, hangs device

    - by Ben Collins
    I'm trying to set up a core plot that looks somewhat like the AAPLot example on the core-plot wiki. I have set up my plot like this: - (void)initGraph:(CPXYGraph*)graph forDays:(NSUInteger)numDays { self.cplhView.hostedLayer = graph; graph.paddingLeft = 30.0; graph.paddingTop = 20.0; graph.paddingRight = 30.0; graph.paddingBottom = 20.0; CPXYPlotSpace *plotSpace = (CPXYPlotSpace*)graph.defaultPlotSpace; plotSpace.xRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(0) length:CPDecimalFromFloat(numDays)]; plotSpace.yRange = [CPPlotRange plotRangeWithLocation:CPDecimalFromFloat(0) length:CPDecimalFromFloat(1)]; CPLineStyle *lineStyle = [CPLineStyle lineStyle]; lineStyle.lineColor = [CPColor blackColor]; lineStyle.lineWidth = 2.0f; // Axes NSLog(@"Setting up axes"); CPXYAxisSet *xyAxisSet = (id)graph.axisSet; CPXYAxis *xAxis = xyAxisSet.xAxis; // xAxis.majorIntervalLength = CPDecimalFromFloat(7); // xAxis.minorTicksPerInterval = 7; CPXYAxis *yAxis = xyAxisSet.yAxis; // yAxis.majorIntervalLength = CPDecimalFromFloat(0.1); // Line plot with gradient fill NSLog(@"Setting up line plot"); CPScatterPlot *dataSourceLinePlot = [[[CPScatterPlot alloc] initWithFrame:graph.bounds] autorelease]; dataSourceLinePlot.identifier = @"Data Source Plot"; dataSourceLinePlot.dataLineStyle = nil; dataSourceLinePlot.dataSource = self; [graph addPlot:dataSourceLinePlot]; CPColor *areaColor = [CPColor colorWithComponentRed:1.0 green:1.0 blue:1.0 alpha:0.6]; CPGradient *areaGradient = [CPGradient gradientWithBeginningColor:areaColor endingColor:[CPColor clearColor]]; areaGradient.angle = -90.0f; CPFill *areaGradientFill = [CPFill fillWithGradient:areaGradient]; dataSourceLinePlot.areaFill = areaGradientFill; dataSourceLinePlot.areaBaseValue = CPDecimalFromString(@"320.0"); // OHLC plot NSLog(@"OHLC Plot"); CPLineStyle *whiteLineStyle = [CPLineStyle lineStyle]; whiteLineStyle.lineColor = [CPColor whiteColor]; whiteLineStyle.lineWidth = 1.0f; CPTradingRangePlot *ohlcPlot = [[[CPTradingRangePlot alloc] initWithFrame:graph.bounds] autorelease]; ohlcPlot.identifier = @"OHLC"; ohlcPlot.lineStyle = whiteLineStyle; ohlcPlot.stickLength = 2.0f; ohlcPlot.plotStyle = CPTradingRangePlotStyleOHLC; ohlcPlot.dataSource = self; NSLog(@"Data source set, adding plot"); [graph addPlot:ohlcPlot]; } And my delegate methods like this: #pragma mark - #pragma mark CPPlotdataSource Methods - (NSUInteger)numberOfRecordsForPlot:(CPPlot *)plot { NSUInteger maxCount = 0; NSLog(@"Getting number of records."); if (self.data1 && [self.data1 count] > maxCount) { maxCount = [self.data1 count]; } if (self.data2 && [self.data2 count] > maxCount) { maxCount = [self.data2 count]; } if (self.data3 && [self.data3 count] > maxCount) { maxCount = [self.data3 count]; } NSLog(@"%u records", maxCount); return maxCount; } - (NSNumber *)numberForPlot:(CPPlot *)plot field:(NSUInteger)fieldEnum recordIndex:(NSUInteger)index { NSLog(@"Getting record @ idx %u", index); return [NSNumber numberWithInt:index]; } All the code above is in the view controller for the view hosting the plot, and when initGraph is called, numDays is 30. I realize of course that this plot, if it even worked, would look nothing like the AAPLot example. The problem I'm having is that the view is never shown. It finished loading because viewDidLoad is the method that calls initGraph above, and the NSLog statements indicate that initGraph finishes. What's strange is that I return a value of 54 from numberOfRecordsForPlot, but the plot asks for more than 54 data points. in fact, it never stops asking. The NSLog statement in numberForPlot:field:recordIndex prints forever, going from 0 to 54 and then looping back around and continuing. What's going on? Why won't the plot stop asking for data and draw itself?

  • Reading email address from contacts fails with weird memory issue - Solved

    - by CapsicumDreams
    Hi all, I'm stumped. I'm trying to get a list of all the email address a person has. I'm using the ABPeoplePickerNavigationController to select the person, which all seems fine. I'm setting my ABRecordRef personDealingWith; from the person argument to - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier { and everything seems fine up till this point. The first time the following code executes, all is well. When subsequently run, I can get issues. First, the code: // following line seems to make the difference (issue 1) // NSLog(@"%d", ABMultiValueGetCount(ABRecordCopyValue(personDealingWith, kABPersonEmailProperty))); // construct array of emails ABMultiValueRef multi = ABRecordCopyValue(personDealingWith, kABPersonEmailProperty); CFIndex emailCount = ABMultiValueGetCount(multi); if (emailCount > 0) { // collect all emails in array for (CFIndex i = 0; i < emailCount; i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [emailArray addObject:(NSString *)emailRef]; CFRelease(emailRef); } } // following line also matters (issue 2) CFRelease(multi); If compiled as written, the are no errors or static analysis problems. This crashes with a *** -[Not A Type retain]: message sent to deallocated instance 0x4e9dc60 error. But wait, there's more! I can fix it in either of two ways. Firstly, I can uncomment the NSLog at the top of the function. I get a leak from the NSLog's ABRecordCopyValue every time through, but the code seems to run fine. Also, I can comment out the CFRelease(multi); at the end, which does exactly the same thing. Static compilation errors, but running code. So without a leak, this function crashes. To prevent a crash, I need to haemorrhage memory. Neither is a great solution. Can anyone point out what's going on? Solution: It turned out that I wasn't storing the ABRecordRef personDealingWith var correctly. I'm still not sure how to do that properly, but instead of having the functionality in another routine (performed later), I'm now doing the grunt-work in the delegate method, and using the derived results at my leisure. The new (working) routine: - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person { // as soon as they select someone, return personDealingWithFullName = (NSString *)ABRecordCopyCompositeName(person); personDealingWithFirstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty); // construct array of emails [personDealingWithEmails removeAllObjects]; ABMutableMultiValueRef multi = ABRecordCopyValue(person, kABPersonEmailProperty); if (ABMultiValueGetCount(multi) > 0) { // collect all emails in array for (CFIndex i = 0; i < ABMultiValueGetCount(multi); i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [personDealingWithEmails addObject:(NSString *)emailRef]; CFRelease(emailRef); } } CFRelease(multi); return NO; }

  • Asynchronous Image loading in certain custom UITableViewCells

    - by Dan
    So, I'm sure that this issue has been brought up before, but I haven't quite seen a solution for my specific problem. What I'm doing is loading a group of custom UITableViewCell's that are drawn using Loren Brichter's solution, each cell has some content, an icon (representing the user) that is asynchronously loaded into it, and a few other things. Eventually, I'm hoping to add support for images. Not every cell has an image, so in the creation of the cell, it determines if an image is required to be loaded and drawn into the cell. My problem is that I don't know how I can do that while keeping the image loaded asynchronously - with not every cell having the need to load an image (like needed with the icon) I'm not sure how to keep it in order when an cell is thrown off screen and re-rendered when the user scrolls over it. Each cell draws it content from an NSArray containing a custom object called FeedItem. All I'm really looking for is some sort of solution or idea to help me because right now I am at a loss. Thanks guys, I will appreciate the help.

  • Updating UIView subclass contents

    Hi; I am trying to update a UIView subclass to draw individual pixels (rectangles) after calculating if they are in the mandelbrot set. I am using the following code but am getting a blank screen: //drawingView.h ... -(void)drawRect:(CGRect)rect{ CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetRGBFillColor(context, r, g, b, 1); CGContextSetRGBStrokeColor(context, r, g, b, 1); CGRect arect = CGRectMake(x,y,1,1); CGContextFillRect(context, arect); } ... //viewController.m ... - (void)viewDidLoad { [drawingView setX:10]; [drawingView setY:10]; [drawingView setR:0.0]; [drawingView setG:0.0]; [drawingView setB:0.0]; [super viewDidLoad]; [drawingView setNeedsDisplay]; } Once I figure out how to display one pixel, I'd like to know how to go about updating the view by adding another pixel (once calculated). Once all the variables change, how do I keep the current view as is but add another pixel? Thanks, Brett

  • Trouble using opaque pointers in Objective C++

  • Core Data - NSPredicate to filter to-many relationship

    - by Macatomy
    I have 2 entities, Task and List. Each task has a to-one relationship to a List object called "list", and there is an inverse relationship with List, which has a to-many relationship with Task called "tasks". I'm trying to use a fetch request with an NSPredicate to get all the Task objects that belong to a specified List: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"list=%@", theList]; [fetchRequest setPredicate:predicate]; (where "theParent" is a reference to a List object). However this returns no fetched objects. If I take out the predicate, then the objects are returned (so I do know they exist, and by NSLogging theList I know it has Task objects associated with it).

  • UITableView, force to snap to whole UITableViewCell at top of table

    - by Adam Eberbach
    I have a need to make a UITableView only display whole cells at the top of the cell, so when the table is moved or scrolled it should animate to make a whole cell visible at the top of the table if it has happened to stop with a cell partially off the top. This can be easily done using visibleCells and scrollToRowAtIndexPath methods of UITableView, BUT the cell should not always scroll down to move the partial cell into view - if the cell at top is more than 50% gone it should go completely with the next cell (i.e. index 1 in the array returned by visibleCells) moving to the top of the table. I've tried a few things to make this happen but I don't think I am understanding the way frame and bounds work between a UITableView and its UITableViewCells. Any help?

  • How does glClear() improve performance?

    - by Jon-Eric
    Apple's Technical Q&A on addressing flickering (QA1650) includes the following paragraph. (Emphasis mine.) You must provide a color to every pixel on the screen. At the beginning of your drawing code, it is a good idea to use glClear() to initialize the color buffer. A full-screen clear of each of your color, depth, and stencil buffers (if you're using them) at the start of a frame can also generally improve your application's performance. On other platforms, I've always found it to be an optimization to not clear the color buffer if you're going to draw to every pixel. (Why waste time filling the color buffer if you're just going to overwrite that clear color?) How can a call to glClear() improve performance?
