在我的应用程序中，我想显示coverflow过程，我从网上获得了代码，使用默认数组时它工作正常，但是在使用json Webservices时它不会连续显示图像，它只显示一个图像，我希望所有图像都是连续显示。这是示例代码，
- (void)viewDidLoad
{
NSString *Categor=@"http://hrmsiphone.atrity.info:7006/HRMSService.svc/
GetEmployeeDesignationByLocation/Date=%@,AP=%@,Unit=%@,Location=%@";
Date = @"2013-04-24";
AP = @"A";
Unit = @"A-UNIT-FULLSHOES";
Location = @"Unit";
NewDic2 = [Array objectAtIndex:0];
NSString *Category = [NSString stringWithFormat:Categor,Date,AP,Unit,Location];
dispatch_sync(kBgQueue, ^{
NSData* data = [NSData dataWithContentsOfURL: kLatestURL];
[self performSelectorOnMainThread:@selector(fetchedData:)
withObject:data
waitUntilDone:YES];
});
- (void)fetchedData:(NSData *)responseData
{
NSError* error;
NSDictionary* json = [NSJSONSerialization
JSONObjectWithData:responseData
options:kNilOptions
error:&error];
NSArray* Increment = [ json objectForKey:@"GetEmployeeDesignationByLocationResult"];
self.Details2 = Increment;
NSLog(@"Index: %@",Increment);
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [Details2 count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:
(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = @"AttenEmpPhto";
AttenEmpPhto *cell = (AttenEmpPhto *)[tableView
dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"AttenEmpPhto" owner:self
cell = [nib objectAtIndex:0];
}
self.NewDic1=[self.Details2 objectAtIndex:indexPath.row];
cell.Name.text = [NSString stringWithFormat:@"%@", [self.NewDic1 objectForKey:
@"Employee_Name"]];
UIImageView *imageView = [[UIImageView alloc] initWithFrame:cell.frame];
UIImage *image = [UIImage imageNamed:@"003923_full.jpg"];
imageView.image = image;
cell.backgroundView = imageView;
NSString *imageURL=@"http://hrmsiphone.atrity.info:7006/HRMSService.svc/
GetEmpImage/EmployeeNo=%@";
NSLog(@"Image: %@", imageURL);
NSString *empImage = [NSString stringWithFormat:imageURL,[self.NewDic1 objectForKey:
@"Employee_No"]];
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:empImage]];
covers = [NSMutableArray arrayWithObjects:[UIImage imageWithData:imageData],nil];
NSLog(@"Image: %@", covers);
NSLog(@"Image: %@", imageData);
coverflow = [[TKCoverflowView alloc] initWithFrame:CGRectMake(0, 50, 500, 300)];
coverflow.coverflowDelegate = self;
coverflow.DataSource = self;
[self.view addSubview:coverflow];
[coverflow setNumberOfCovers:10];
return cell;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)
interfaceOrientation
{
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}
#pragma Coverflow delegate methods
- (void) coverflowView:(TKCoverflowView*)coverflowView coverAtIndexWasBroughtToFront:
(int)index{
NSLog(@"Front %d",index);
}
- (TKCoverflowCoverView*) coverflowView:(TKCoverflowView*)coverflowView coverAtIndex:
(int)index
{
TKCoverflowCoverView *cover = [coverflowView dequeueReusableCoverView];
if(cover == nil){
// Change the covers size here
cover = [[TKCoverflowCoverView alloc] initWithFrame:CGRectMake(0, 0, 224,
300)];
cover.baseline = 224;
}
cover.image = [covers objectAtIndex:index % [covers count]];
这里 [covers count] 返回 1 ，但我需要 2(EmployeeNo - 1 & 3)
NSLog(@"CC: %lu", (unsigned long)[covers count] );
NSLog(@"CM: %@", cover.image );
return cover;
}
- (void) coverflowView:(TKCoverflowView*)coverflowView coverAtIndexWasDoubleTapped:
(int)index{
TKCoverflowCoverView *cover = [coverflowView coverAtIndex:index];
if(cover == nil) return;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:cover
cache:YES];
[UIView commitAnimations];
// NSLog(@"Index: %d",index);
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
}
提前致谢。
