View Controller not Displaying - ios

I'm working on a baseball game app that contains multiple Modal View Controllers. However, when I make the modal transition from "BasicGameSetupViewController" to "BasicViewController", the transition happens (because I have NSLog statements within my ViewDidLoad method in the BasicViewController), but the actual view does not update. Here is the method where I transition to the BasicViewController (this code is in BasicGameSetupViewController):
- (IBAction)pressedBeginPlay:(id)sender {
numOfInnings = [selectInnings selectedSegmentIndex];
numOfInnings = numOfInnings + 1;
row = [teamSelector selectedRowInComponent:0];
visitor = [teams objectAtIndex:row];
row = [teamSelector selectedRowInComponent:1];
home = [teams objectAtIndex:row];
NSLog(#"%#", visitor);
NSLog(#"%#", home);
if([awaySelect selectedSegmentIndex] == 0)
{
awayPlayer = #"Human";
}
else
{
awayPlayer = #"CPU";
}
if([homeSelect selectedSegmentIndex] == 0)
{
homePlayer = #"Human";
}
else
{
homePlayer = #"CPU";
}
[self performSegueWithIdentifier:#"startBeginnerToBasic" sender:self];
}
(This block also has a "prepareForSegue" method)
And here is the viewDidLoad method in BasicViewController:
- (void)viewDidLoad{
NSLog(#"Made it to basic View controller");
homeLineup = [[NSMutableArray alloc] initWithCapacity:9];
visitorLineup = [[NSMutableArray alloc] initWithCapacity:9];
batter = [[NSMutableArray alloc] initWithCapacity:22];
homePitcher = [[NSMutableArray alloc] initWithCapacity:22];
awayPitcher = [[NSMutableArray alloc] initWithCapacity:22];
pitcher = [[NSMutableArray alloc] initWithCapacity:22];
homeAlreadyPitched = [[NSMutableArray alloc]initWithCapacity:5];
awayAlreadyPitched = [[NSMutableArray alloc] initWithCapacity:5];
NSLog(#"arrays initialized");
[super viewDidLoad];
[self setUpTeams];
[self checkForComputer];
[self newBatter];
[self atBat];
// Do any additional setup after loading the view.
}
I'm completely stumped as to why my view isn't showing. The NSLog statements that are in the ViewDidLoad code block above show up, but the I can't get the view to show. Does anyone have any ideas?
Thank you in advance for your help!

Not able to scroll and select cells displayed in uisearch controller

I have a screen which shows favourite locations and if a user wants to add new location he can search using uisearchcontroller and add it to favourite location's list.
The problem is that once i make the api call for autocomplete the list of searched locations is visible but i cannot select or scroll the table.
I know that the problem is where i set the uisearchcontroller. but i do not know the right way to do it.
I am newbie in iOS so ur suggestions will be welcome.
the following is the GithubRepository for the project(incase ul want to try out the app and make suggestions)
and heres the related code where i beleive the problem exists.
- (void)viewDidLoad {

UITableView sorting

I've been brought in on this project where the previous developers made custom table cells and headers by using xib files and then registering the nibs like so:
[self.accountTable registerNib:[UINib nibWithNibName:kNonATITableViewCellLandscapeNib bundle:[NSBundle mainBundle]] forCellReuseIdentifier:kNonATITableViewCellLandscapeIdentifier];
[self.accountTable registerNib:[UINib nibWithNibName:kNonATITableHeaderLandscapeNib bundle:[NSBundle mainBundle]] forCellReuseIdentifier:kNonATITableHeaderLandscapeId];
The header files have buttons in them and uiimageviews. The buttons are for sorting, the uiimageviews for an arrow icon to show you the direction of the sort (asc, desc). All the buttons and imageviews are IBOutlets. All the buttons are linked to an IBAction:
- (IBAction)sortButtonTouched:(id)sender;
The file also has two other properties:
#property (nonatomic, assign) SortType currentSortingOption;
#property (nonatomic, strong) UIButton* btnLastTouched;
Here is sortButtonTouched:
- (IBAction)sortButtonTouched: (UIButton*) buttonTouched {
if (!self.btnLastTouched) {
self.btnLastTouched = buttonTouched;
}
NSString* strFieldToSort;
UIImageView* ivSortImage;
NSArray* arrSortIcons = [[NSArray alloc] initWithObjects:self.ivAccountSort,self.ivNameSort, self.ivAddressSort, self.ivCitySort, self.ivZipSort, self.ivLastCallSort, self.ivMileageSort, nil];
//get the image for the button selected
if (buttonTouched.tag == 0) {
strFieldToSort = #"customerNumber";
ivSortImage = self.ivAccountSort;
} else if (buttonTouched.tag == 1) {
strFieldToSort = #"customerName";
ivSortImage = self.ivNameSort;
} else if (buttonTouched.tag == 2) {
strFieldToSort = #"address";
ivSortImage = self.ivAddressSort;
} else if (buttonTouched.tag == 3) {
strFieldToSort = #"city";
ivSortImage = self.ivCitySort;
} else if (buttonTouched.tag == 4) {
strFieldToSort = #"zip";
ivSortImage = self.ivZipSort;
} else if (buttonTouched.tag == 5) {
strFieldToSort = #"lastCallDate";
ivSortImage = self.ivLastCallSort;
} else if (buttonTouched.tag == 6) {
strFieldToSort = #"mileage";
ivSortImage = self.ivMileageSort;
}
//set the sort option and add icon
if (!self.currentSortingOption) {
self.currentSortingOption = SORT_ASC;
[ivSortImage setImage:[UIImage imageNamed:Ascending_Icon]];
} else {
if (![self.btnLastTouched isEqual:buttonTouched]) {
self.currentSortingOption = SORT_ASC;
[ivSortImage setImage:[UIImage imageNamed:Ascending_Icon]];
} else {
if (self.currentSortingOption == SORT_ASC) {
self.currentSortingOption = SORT_DESC;
[ivSortImage setImage:[UIImage imageNamed:Descending_Icon]];
} else {
self.currentSortingOption = SORT_ASC;
[ivSortImage setImage:[UIImage imageNamed:Ascending_Icon]];
}
}
}
//show and hide
for(int i=0; i<arrSortIcons.count; i++) {
UIImageView* ivThisImage = [arrSortIcons objectAtIndex:i];
if (buttonTouched.tag == i) {
[UIView animateWithDuration:.25 animations:^(void) {
ivThisImage.alpha = 1.0;
}];
} else {
[UIView animateWithDuration:.25 animations:^(void) {
ivThisImage.alpha = 0.0;
}];
}
}
//call back to routing view controller and sort results based on sort order and field selected
NSDictionary* dictUserData = [[NSDictionary alloc] initWithObjectsAndKeys:
#"Sort Non-ATI", #"Action",
strFieldToSort, #"Field To Sort",
[NSNumber numberWithLong:self.currentSortingOption], #"Sortng Option",
nil];
[[NSNotificationCenter defaultCenter] postNotificationName:#"rvc" object:self userInfo:dictUserData];
self.btnLastTouched = buttonTouched;
}
And the notification fires this method:
- (void) sortNonATIResults : (NSDictionary*) dictSortParams {
if (self.arrNonATIResults.count > 0) {
NSString* sortKey = [dictSortParams objectForKey:#"Field To Sort"];
//change the field to sort to match the customerInfo object properties...
NSNumber* numSortType = [dictSortParams objectForKey:#"Sortng Option"];
BOOL isAsc = YES;
if ([numSortType intValue] == 2) {
isAsc = NO;
}
NSSortDescriptor* sortDescriptor = [[NSSortDescriptor alloc] initWithKey:sortKey ascending:isAsc];
NSArray* arrSortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil];
NSArray* arrSortedNonATIResults = (NSArray*)[self.arrNonATIResults sortedArrayUsingDescriptors:arrSortDescriptors];
self.arrNonATIResults = [arrSortedNonATIResults mutableCopy];
self.arrDatasource = self.arrNonATIResults;
[self.accountTable reloadData];
}
}
There are two problems right now. The icons are not showing up if the notification is sent. Comment out the notification and they function as expected. The other problem is that the property currentSortingOption doesn't retain it's value. I think both issues are related but I am not 100% sure. When the tableview is reloaded, does the header get instantiated again? This would make sense to me since then the uiimageviews would be reset with no image and the property would lose it's value and reset to 0 (it is the value of a typedef).
So, I am correct, how can I resolve this and if not, what could be causing the problems?
Thanks
OK, sorry for posting and then solving my problem right away, I guess sometimes you just need to write out the problem to find the solution. All I needed to do was not reload the table but just reload the rows. Here's the updated method:
(void) sortNonATIResults : (NSDictionary*) dictSortParams {
if (self.arrNonATIResults.count > 0) {
NSString* sortKey = [dictSortParams objectForKey:#"Field To Sort"];
//change the field to sort to match the customerInfo object properties...
NSNumber* numSortType = [dictSortParams objectForKey:#"Sortng Option"];
BOOL isAsc = YES;
if ([numSortType intValue] == 2) {
isAsc = NO;
}
NSSortDescriptor* sortDescriptor = [[NSSortDescriptor alloc] initWithKey:sortKey ascending:isAsc];
NSArray* arrSortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil];
NSArray* arrSortedNonATIResults = (NSArray*)[self.arrNonATIResults sortedArrayUsingDescriptors:arrSortDescriptors];
self.arrNonATIResults = [arrSortedNonATIResults mutableCopy];
self.arrDatasource = self.arrNonATIResults;
dispatch_async(dispatch_get_main_queue(), ^{
NSMutableArray *indexPathArray = [[NSMutableArray alloc] init];
for (NSInteger section = 0; section < [self.accountTable numberOfSections]; ++section)
{
for (NSInteger row = 0; row < [self.accountTable numberOfRowsInSection:section]; ++row)
{
[indexPathArray addObject:[NSIndexPath indexPathForRow:row inSection:section]];
}
}
[self.accountTable reloadRowsAtIndexPaths:indexPathArray withRowAnimation:UITableViewRowAnimationNone];
[self.accountTable scrollsToTop];
});
}
}

View doesn't scroll to selected element QuickDialog

I'm trying to implement a basic QuickDialog view and the placement of the elements works fine.
But when I select an element the view won't scroll it into view. I thought the library would do this by itself or am I missing something?
Here is my code:
- (id)initWithCoder:(NSCoder *)aDecoder {
if ((self = [super initWithCoder:aDecoder])) {
QRootElement *root = [[QRootElement alloc] init];
root.title = #"";
root.grouped = YES;
self.root = root;
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
QSection *driverSection = [[QSection alloc] initWithTitle:#"xxx"];
QEntryElement *lblDriverSsn = [[QEntryElement alloc] initWithTitle:#"xxx" Value:#""];
lblDriverSsn.key = #"driverSsn";
QSection *vehicleSection = [[QSection alloc] initWithTitle:#"xxx"];
NSArray *component1 = #[#"xxx", #"xxx"];
QPickerElement *EventDescriptionPicker = [[QPickerElement alloc] initWithTitle:#"xxx" items:#[component1] value:#""];
EventDescriptionPicker.key = #"eventDescription";
NSMutableArray *speedValues = [[NSMutableArray alloc]init];
for (int i = 0; i <= 201; i+=5)
{
[speedValues addObject:[NSString stringWithFormat:#"%d%#", i,#" km/h"]];
}
QPickerElement *vehicleSpeed = [[QPickerElement alloc] initWithTitle:#"xxx" items:#[speedValues] value:#""];
self.damageReported = [[QBooleanElement alloc] initWithTitle:#"xxx" BoolValue:NO];
self.damageReported.onImage = [UIImage imageNamed:#"imgOn"];
self.damageReported.offImage = [UIImage imageNamed:#"imgOff"];
self.damageReported.controllerAction = #"showReportNumber:";
QEntryElement *lblReportNumber = [[QEntryElement alloc] initWithTitle:#"xxx" Value:#""];
lblDriverSsn.key = #"reportNumber";
//Sections
[driverSection addElement:lblDriverSsn];
[self.root addSection:driverSection];
[vehicleSection addElement:EventDescriptionPicker];
[vehicleSection addElement:vehicleSpeed];
[vehicleSection addElement:self.damageReported];
[vehicleSection addElement:lblReportNumber];
[self.root addSection:vehicleSection];
}
Am I missing something here?
Thanks in advance
On your initWithCoder: , set the following:
self.resizeWhenKeyboardPresented =YES;
This causes the view controller to listen for keyboard notifications , and adjust the inset accordingly.

Error jumping between viewControllers

Having some difficultly with this one.
I am loading questions, answers, correct answers from a plist. All data is being read in fine and looks like below
- (void)viewDidLoad
{
[super viewDidLoad];
rootArray = [NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"question" ofType:#"plist"]];
currentQuestion = -1;
[self showNextQuestion];
}
-(void) showNextQuestion{
currentQuestion++;
int numItems = [rootArray count];
NSMutableArray *question = [NSMutableArray arrayWithCapacity:numItems];
NSMutableArray *A = [NSMutableArray arrayWithCapacity:numItems];
NSMutableArray *B = [NSMutableArray arrayWithCapacity:numItems];
NSMutableArray *C = [NSMutableArray arrayWithCapacity:numItems];
NSMutableArray *addimage = [NSMutableArray arrayWithCapacity:numItems];
NSMutableArray *Answer = [NSMutableArray arrayWithCapacity:numItems];
for (NSDictionary *itemData in rootArray) {
[question addObject:[itemData objectForKey:#"question"]];
[A addObject:[itemData objectForKey:#"A"]];
[B addObject:[itemData objectForKey:#"B"]];
[C addObject:[itemData objectForKey:#"C"]];
[addimage addObject:[itemData objectForKey:#"ImageUse"]];
[Answer addObject:[itemData objectForKey:#"ANS"]];
}
self.questionasked.text = question[currentQuestion];
self.answer1.text = A[currentQuestion];
self.answer2.text = B[currentQuestion];
self.answer3.text = C[currentQuestion];
additionImage.image = [UIImage imageNamed:addimage[currentQuestion]];
self.correctAns = Answer[currentQuestion];
if(currentQuestion == 4){
[ self performSegueWithIdentifier:#"levelclear" sender:nil];// here I am performing a segue to indicate that when 4 questions are displayed it will go to this view controller
}
}
I have 3 buttons in my VC, One for each option A,B,C which all have a function
- (IBAction)SelectA:(id)sender {
if ([self.correctAns isEqualToString:#"A"]) {
currentQuestion ++;
[self showNextQuestion];
}
else{
[self performSegueWithIdentifier:#"incorrect" sender:nil];
}
}
- (IBAction)SelectB:(id)sender {
if ([self.correctAns isEqualToString:#"B"]) {
currentQuestion ++;
[self showNextQuestion];
}
else{
[self performSegueWithIdentifier:#"incorrect" sender:nil];
}
}
- (IBAction)SelectC:(id)sender {
if ([self.correctAns isEqualToString:#"C"]) {
currentQuestion ++;
[self showNextQuestion];
}
else{
[self performSegueWithIdentifier:#"incorrect" sender:nil];
}
}
When I answer the question correctly it moves to the next question. However when I answer it incorrectly it goes to the incorrect VC informing of the incorrect question. This VC has a segue when the button is pressed to go back to the question VC(which I made in the storyboard). It does go back to the question VC but simply jumps back to the first question. I know it is something regarding the currentQuestion but not sure what.
Looks like when you segue to the incorrect answer you are destroying the questions view controller, and when yo go back to it, it is re created.

I tried to put my code on a new project (empty application) and it worked fine, i didn't understand that error and its possible causes.
EDIT:
I tried to track the problem by elimination,and my code worked fine when i remove this method:
//Invoked when the class is instantiated in XIB
-(id)initWithCoder:(NSCoder*)aDecoder
{
self = [super initWithCoder:aDecoder];
if( self)
{
[self customInitialization];
}
return self;
}
However, when i run, my app doesn't display me the route between the two points (The purpose of the app). So this method seems important for the whole class because without it, i couldn't get the route and in the other side when it's there, the app crashes. How should i deal with this contradiction?
#Vince is putting you on the right track. Since the problem is in an NSURL method being called by a framework (Google Maps in this case) you need to debug what you are passing to the framework. You have the source for the framework also right? You can set breakpoints in loadWithStartPoint:endPoint:options:] to see what's going on.
One thing I did notice is you are passing an NSMutableArray as the endPoint param when I believe it expects an NSString.
