How to display Twitter Feed into a UITableView - xcode

I am trying to display twitter feed into a UITableView. I was able to get the feeds and NSLog the information. However, I am confused as to how to display the information instead of logging it to the console. I was told to create a custom object in order to store the desired data from the feed and then make a UITableVIew to display the information, and that is where I get stuck. Are there any suggestions or could anyone point me in the right direction? Here is how my code looks right now. I appreciate any help and thank you for your valuable time.
CODE BELOW:
#import "ViewController.h"
#import <Accounts/Accounts.h>
#import <Social/Social.h>
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[self refreshTwitter];
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
-(void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
-(void)refreshTwitter
{
ACAccountStore *accountStore = [[ACAccountStore alloc]init];
if (accountStore != nil)
{
ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
if (accountType != nil)
{
[accountStore requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error)
{
if (granted)
{
//Succesful Access
NSArray *twitterAccounts = [accountStore accountsWithAccountType:accountType];
if (twitterAccounts != nil)
{
ACAccount *currentAccount = [twitterAccounts objectAtIndex:0];
if (currentAccount != nil)
{
NSString *requestString = #"https://api.twitter.com/1.1/statuses/user_timeline.json";
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:[NSURL URLWithString:requestString] parameters:nil];
[request setAccount:currentAccount];
[request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error)
{
if ((error == nil) && ([urlResponse statusCode] == 200))
{
NSArray *twitterFeed = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:nil];
NSDictionary *firstPost = [twitterFeed objectAtIndex:0];
NSLog(#"firstPost = %#", [firstPost description]);
}
}];
}
}
}
else
{
//Access Denied
}
}];
}
}
}
#end

core-plot x-axis label not visible - bounding rects?

Using the vertical bar chart sample as a start, I created a chart whose y values are 0..1, x values 1..n but the x label index supplied for CPTBarPlotFieldBarLocation cell of my data source doesn't appear; I don't use y-axis labels.
I suspect I'm clipping them. Is there a way, like in the old IB, to draw the various graph region's bounding rect?
The x-axis plot labels are a non-numeric string as in the example. What did I break? Here's my setup

If there were visible clues - drawn bounding rects, I think a lot of us could benefit from them (I miss those from IB circa v3).
The statement x.labelFormatter = nil; eliminates the automatic axis labels. If you supply a label formatter and label text style, the axis will create ticks and labels automatically based on the labeling policy.

How to fetch photos from Picasa album?

I am developing an application which need to display photos from Picasa web album.
I have search about it. I got following links.
https://code.google.com/p/gdata-objectivec-client/
I have downloaded GData and also included all required folder into xcode.
The code which i have written is here.
- (void) loadPhotoGallery{
username = #"xyz";
password = #"abc";
GDataServiceGooglePhotos *photosService;
photosService = [self photoService];
NSURL *url = [GDataServiceGooglePhotos photoFeedURLForUserID:#"user" albumID:#"ablumID" albumName:nil photoID:nil kind:nil access:nil];
GDataQueryGooglePhotos *introspectQuery;
introspectQuery = [GDataQueryGooglePhotos photoQueryWithFeedURL:url];
[introspectQuery setResultFormat:kGDataQueryResultServiceDocument];
GDataServiceTicket *ticket;
ticket = [photosService fetchFeedWithQuery:introspectQuery delegate:self didFinishSelector:#selector(introspectTicket:finishedWithServiceDocument:error:)];
}
- (void)introspectTicket:(GDataServiceTicket *)ticket
finishedWithServiceDocument:(GDataAtomServiceDocument *)serviceDoc
error:(NSError *)error {
if (error == nil) {
GDataAtomCollection *collection = [[serviceDoc primaryWorkspace] primaryCollection];
NSArray *theMIMETypes = [collection serviceAcceptStrings];
}
}
-(GDataServiceGooglePhotos *)photoService{
static GDataServiceGooglePhotos *service = nil;
username = #"xyz";
password = #"abc";
if (!service) {
service = [[GDataServiceGooglePhotos alloc] init];
[service setShouldCacheDatedData:YES];
[service setServiceShouldFollowNextLinks:YES];
[service setIsServiceRetryEnabled:YES];
}
if ([username length] > 0 && [password length] > 0) {
[service setUserCredentialsWithUsername:username
password:password];
} else {
// fetch unauthenticated
[service setUserCredentialsWithUsername:nil
password:nil];
}
return service;
}
But i am very confused with this code.
Can anyone help. how to start code for fetching photos?
Thanks in advance.
I have resolve this. I have make two changes.
1. Edit loadPhotoGallery method
2. Create new method for fetching photos and displayed into grid.
My code for loadPhotoGallery is following.
- (void) loadPhotoGallery{
NSLog(#"fetchAllPhotos");
GDataServiceGooglePhotos *service = [self photoService];
GDataServiceTicket *ticket;
NSURL *feedURL = [GDataServiceGooglePhotos photoFeedURLForUserID:#"xyz#gmail.com" albumID:#"12345" albumName:nil photoID:nil kind:nil access:nil];
ticket = [service fetchFeedWithURL:feedURL delegate:self didFinishSelector:#selector(photosListTicket:finishedWithFeed:error:)];
feedURL = nil;
}
And code for displaying Photos into Grid is following.

Vfr-Reader UIScrollView from left to right

I'm using the Vfr-Reader source code and here I'm not able to scroll the scrollview from left to right, and by default it is from right to left. How can I achieve this I tried many just setting the offset and also tried putting the condition with the origin.
- (void)showDocumentPage:(NSInteger)page
{
if (page != currentPage) // Only if different
{
NSInteger minValue; NSInteger maxValue;
NSInteger maxPage = [document.pageCount integerValue];
NSInteger minPage = 1;
if ((page < minPage) || (page > maxPage)) return;
if (maxPage <= PAGING_VIEWS) // Few pages
{
minValue = minPage;
maxValue = maxPage;
}
else // Handle more pages
{
minValue = (page - 1);
maxValue = (page + 1);
if (minValue < minPage)
{minValue++; maxValue++;}
else
if (maxValue > maxPage)
{minValue--; maxValue--;}
}
NSMutableIndexSet *newPageSet = [NSMutableIndexSet new];

CGRect viewRect = CGRectZero; viewRect.size = theScrollView.bounds.size;
for (NSInteger number = minValue; number <= maxValue; number++)
{

contentView = [[ReaderContentView alloc] initWithFrame:viewRect fileURL:fileURL page:number password:phrase];
[theScrollView addSubview:contentView]; [contentViews setObject:contentView forKey:key];
contentView.message = self; [newPageSet addIndex:number];
}
else // Reposition the existing content view

}

}

CGFloat viewWidthX2 = (viewWidthX1 * 2.0f);
CGPoint contentOffset = CGPointZero;
if (maxPage >= PAGING_VIEWS)
{
if (page == maxPage)
contentOffset.x = viewWidthX2;
else
if (page != minPage)
contentOffset.x = viewWidthX1;
}
else
if (page == (PAGING_VIEWS - 1))

if (CGPointEqualToPoint(theScrollView.contentOffset, contentOffset) == false)

}
I changed this
if (maxPage <= PAGING_VIEWS) // Few pages
{
minValue = minPage;
maxValue = maxPage;
}
else // Handle more pages
{
minValue = (page - 1);
maxValue = (page + 1);
if (minValue < minPage)
{minValue++; maxValue++;}
else
if (maxValue > maxPage)
{minValue--; maxValue--;}
}
</pre>
I got the correct minValue and max value to load the left page and right page once you are on the current page, for example if I'm on the 3 page, then on the left side it should be 4 and right side should be 2 but it's not loading these instead it loads left side 2 and right side 5. Something that I'm missing can anyone help me out.

GL_STACK_OVERFLOW (0x503) error Cocos2d

So I have it set up so when the characters health is < 100 (for testing purposes) it stop the scene and goes to the game over scene.
if (playerDataManager.playerHealth < 100) {
[[CCDirector sharedDirector] replaceScene:[CCTransitionFade transitionWithDuration:3 scene: [GameLogic scene]]];
}
However when the players health drops below 100, it goes to the new scene, but the FPS drops dramatically from 60 to 5.
I get a list of OpenGL error 0x0503 in -[EAGLView swapBuffers] then it stays frozen like that for about 40 seconds, then the FPS unfreeze and goes back out to 60 and I get a list of 2012-07-13 10:37:50.234 Tilegame[93513:10a03] cocos2d: removeChildByTag: child not found!
Then I can continue with the app like normal, going back to the main menu, starting a new game, then recreate the error.

OpenGL error 0x503 means GL_STACK_OVERFLOW, it means you are pushing too many things onto the opengl stack.
I see several instances of pushScene in your code, but no instances of pop anything anywhere. You cannot just keep pushing things indefinitely without popping them, or you will get this error.
We need to what is currently running in your scene, how it has been allocated and how it is released. We also need to know the same information for the new loaded scene GameLogic. Edit your question and add these data.

NSArray objectAtIndex is not working. Please help

NSArray* address = [NSArray arrayWithArray:[detailItem addressArray]];
NSLog(#"address = %#", address);
NSString* addressToString = #"";
int arrayCount = [address count];
for (int i = 0; i < arrayCount; i++) {
addressToString = [addressToString stringByAppendingString:[address objectAtIndex:i]];
if (i == arrayCount -1) {
addressToString = [addressToString stringByAppendingString:#""];
} else {
addressToString = [addressToString stringByAppendingString:#", "];
}
}
address is an NSArray that holds an address
2010-06-23 09:05:19.346 iPhoneExample[1093:207] address = (
{
City = "Cupertino";
Country = "United States";
CountryCode = us;
State = CA;
Street = "1 Infinite Loop";
ZIP = 95014;
}
)
I'm trying to go thru the array and create a CSV string so it would look like
Cupertino, "United States", us, CA, "1 Infinite Loop", 95014
However, I keep crashing on
addressToString = [addressToString stringByAppendingString:#", "];
Message I get is
*** -[NSCFDictionary stringByAppendingString:]: unrecognized selector sent to instance 0x1c2f10
UPDATED:
detailItem is an object of type ABContact (custom class).
ABContact has a property called addressArray
#property (nonatomic, readonly) NSArray *addressArray;
the definition of my addressArray is
- (NSArray *) addressArray {return [self arrayForProperty:kABPersonAddressProperty];}
Your "address" is an NSArray of NSDictionary, not an NSArray of NSArray.
To get the values of the dictionary as an array, you can use
[theDictionary allValues]
but there is no guarantee on the order. And I think what you actually need is:
NSMutableString* addressToString = [NSMutableString string]; // use mutable string!
for (NSDictionary* item in address) { // use fast enumeration!
[addressToString appendFormat:#"%#, \"%#\", %#, %#, \"%#\", %#\n",
[item objectForKey:#"City"],
/* etc ... */
];
}
This:
2010-06-23 09:05:19.346 iPhoneExample[1093:207] address = (
{
City = "Cupertino";
Country = "United States";
CountryCode = us;
State = CA;
Street = "1 Infinite Loop";
ZIP = 95014;
}
)
Is a NSDictionary. You will want to access its members with [dictionary objectForKey:'City']
So, your updated code should read:
NSDictionary* address = [detailItem addressArray];
NSLog(#"address = %#", address);
NSString* addressToString = #"";
int counter = 0;
for (id object in myDictionary) {
if (counter != 0)
addressToString = [addressToString stringByAppendingString:#","];
addressToString = [addressToString stringByAppendingString:object];
counter++;
}
If you could change your addressArray method to actually return an array instead of a dictionary, then you could do:
NSString * addressString = [[detailItem addressArray] componentsJoinedByString:#","];
And that's it...
