Question

我正在使用i carousel在coverflow中加载一堆图像，但我没有得到它？..最初我有Signal sigabart问题..之后我编辑了一些代码，视图显示...我错过了什么？...

#import "CollectionViewController.h"

@interface CollectionViewController ()
@property (nonatomic, retain) NSMutableArray *items;
@end

@implementation CollectionViewController

@synthesize carousel;
@synthesize items;




- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
 {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
    // Custom initialization
}
return self;
}

- (void)dealloc
{

carousel.delegate = nil;
carousel.dataSource = nil;
[items release];

[carousel release];
[super dealloc];
}
- (void)viewDidLoad
{
[super viewDidLoad];
carousel.type = iCarouselTypeCoverFlow2;

}

- (void)viewDidUnload
{
[super viewDidUnload];

self.carousel = nil;
}

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

#pragma mark -
#pragma mark iCarousel methods

- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel
{
return [items count];
}

 - (NSUInteger)numberOfVisibleItemsInCarousel:(iCarousel *)carousel
{

return 29;
}


 - (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
 {


//create new view if no view is available for recycling
if (view == nil)
{

    view = [NSArray arrayWithObjects:[UIImage imageNamed:@"gal1.jpg"],
            [UIImage imageNamed:@"gal2.jpg"],
            [UIImage imageNamed:@"gal3.jpg"],

            [UIImage imageNamed:@"gal5.jpg"],
            [UIImage imageNamed:@"gal6.jpg"],
            [UIImage imageNamed:@"gal7.jpg"],
            [UIImage imageNamed:@"gal8.jpg"],
            [UIImage imageNamed:@"gal9.jpg"],
            [UIImage imageNamed:@"gal10.jpg"],
            [UIImage imageNamed:@"gal11.jpg"],
            [UIImage imageNamed:@"gal12.jpg"],
            [UIImage imageNamed:@"gal13.jpg"],
            [UIImage imageNamed:@"gal14.jpg"],
            [UIImage imageNamed:@"gal15.jpg"],
            [UIImage imageNamed:@"gal16.jpg"],
            [UIImage imageNamed:@"gal17.jpg"],
            [UIImage imageNamed:@"gal18.jpg"],
            [UIImage imageNamed:@"gal19.jpg"],
            [UIImage imageNamed:@"gal20.jpg"],
            [UIImage imageNamed:@"gal21.jpg"],
            [UIImage imageNamed:@"gal22.jpg"],
            [UIImage imageNamed:@"gal23.jpg"],
            [UIImage imageNamed:@"gal24.jpg"],
            [UIImage imageNamed:@"gal25.jpg"],
            [UIImage imageNamed:@"gal26.jpg"],
            [UIImage imageNamed:@"gal27.jpg"],
            [UIImage imageNamed:@"gal28.jpg"],

}

else {

}

    return view;
 }

在模拟器上运行时我只是得到屏幕而不是图像？...我被困在这里......

我已经这样做了。试试这个：

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {

        //set up carousel data
        wrap = NO;

        self.items = [NSArray arrayWithObjects:[UIImage imageNamed:@"gal1.jpg"],
            [UIImage imageNamed:@"gal2.jpg"],
            [UIImage imageNamed:@"gal3.jpg"],
            [UIImage imageNamed:@"gal5.jpg"],
            [UIImage imageNamed:@"gal6.jpg"],
            [UIImage imageNamed:@"gal7.jpg"],
            [UIImage imageNamed:@"gal8.jpg"],
            [UIImage imageNamed:@"gal9.jpg"],
            [UIImage imageNamed:@"gal10.jpg"],
            [UIImage imageNamed:@"gal11.jpg"],
            [UIImage imageNamed:@"gal12.jpg"],
            [UIImage imageNamed:@"gal13.jpg"],
            [UIImage imageNamed:@"gal14.jpg"],
            [UIImage imageNamed:@"gal15.jpg"],
            [UIImage imageNamed:@"gal16.jpg"],
            [UIImage imageNamed:@"gal17.jpg"],
            [UIImage imageNamed:@"gal18.jpg"],
            [UIImage imageNamed:@"gal19.jpg"],
            [UIImage imageNamed:@"gal20.jpg"],
            [UIImage imageNamed:@"gal21.jpg"],
            [UIImage imageNamed:@"gal22.jpg"],
            [UIImage imageNamed:@"gal23.jpg"],
            [UIImage imageNamed:@"gal24.jpg"],
            [UIImage imageNamed:@"gal25.jpg"],
            [UIImage imageNamed:@"gal26.jpg"],
            [UIImage imageNamed:@"gal27.jpg"],
            [UIImage imageNamed:@"gal28.jpg"],nil];
}
return self;

}

然后在你的：

- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index
{

    UIView *view = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[items objectAtIndex:index]]];
    return view;
}

哦，还有另一个，请善意编辑你的numberOfVisibleItemsInCarousel并将其设置为return 7;，这样就不会浪费内存，我想。

iCarousel工作代码：

委托方法：

 - (UIView *)carousel:(__unused iCarousel *)carousel viewForItemAtIndex:(NSInteger)index reusingView:(UIView *)view{

   if (view == nil){

    view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 400 , 600)];
    ((UIImageView *)view).image = [UIImage imageNamed:[imageCarosualArray objectAtIndex:index]];
    view.contentMode = UIViewContentModeCenter;
    [view.layer setMasksToBounds:YES];
  }
  return view;
}

数组

中的

多个图像

CarosualArray =[[NSMutableArray    alloc]initWithObjects:@"test1.png",@"test2.png",@"test3.png",@"test4.png",@"test5.png",@"test6.png",@"test7.png",@"test8.png",@"test9.png", nil];

如何使用此代码在iCarousel中加载多个图像？
