在TTLauncherView中加载更多页面

问题描述：

在我的TTLauncherView实现中，只加载第一页。为什么？在TTLauncherView中加载更多页面

我有47个项目在数组中，47个项目div 9个项目，我应该有6个页面。

感谢您的帮助。

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {  


NSMutableString *jsonString = [[NSMutableString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; 
NSDictionary *results = [jsonString JSONValue]; 

NSArray *photos = [[results objectForKey:@"photosets"] objectForKey:@"photoset"]; 

launcherView = [[TTLauncherView alloc] initWithFrame:self.view.bounds]; 
launcherView.backgroundColor = [UIColor whiteColor]; 
launcherView.delegate = self; 
launcherView.columnCount = 3; 

launcherView.persistenceMode = TTLauncherPersistenceModeNone; 
NSMutableArray *itemArray = [[NSMutableArray alloc] init]; 
for (NSDictionary *photo in photos) 
{ 

    NSString *iconURLString = [NSString stringWithFormat:@"http://farm%@.static.flickr.com/%@/%@_%@_s.jpg", 
    [photo objectForKey:@"farm"], [photo objectForKey:@"server"], [photo objectForKey:@"primary"], [photo objectForKey:@"secret"]]; 


    NSDictionary *title = [photo objectForKey:@"title"]; 
    NSString *itemTitle = [title objectForKey:@"_content"]; 
    TTLauncherItem *itemMenu = [[[TTLauncherItem alloc] initWithTitle:itemTitle 
                   image:iconURLString 
                    URL:nil 
                  canDelete:NO] autorelease]; 

    [itemArray addObject:itemMenu];  

} 

launcherView.pages = [NSArray arrayWithObject: itemArray]; 
[self.view addSubview:launcherView]; 

}

答

我记得，TTLauncherView不会将TTLauncherItem自动分解成页面。你需要一个数组数组。第一个数组中的所有启动器项目都将位于第一个页面上，第二个数组中的所有启动器项目都将位于第二个页面等等。使用它已经很长时间了，但我认为这就是有效。

感谢@Darren的暗示！没错，现在正在工作。 – EversonNovka 2012-08-06 13:53:31

我修改后的代码与@Darren

- (void)connectionDidFinishLoading:(NSURLConnection *)connection {  

NSMutableString *jsonString = [[NSMutableString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];  
NSDictionary *results = [jsonString JSONValue];  
NSArray *photos = [[results objectForKey:@"photosets"] objectForKey:@"photoset"]; 
NSMutableArray *itemArray = [[NSMutableArray alloc] init]; 
NSMutableArray *pageArray = [[NSMutableArray alloc] init]; 
NSNumber *countPage = [[NSNumber alloc] initWithInt:0]; 

for (NSDictionary *photo in photos) 
{ 

    NSString *iconURLString = [NSString stringWithFormat:@"http://farm%@.static.flickr.com/%@/%@_%@_s.jpg", 
           [photo objectForKey:@"farm"], [photo objectForKey:@"server"], [photo objectForKey:@"primary"], [photo objectForKey:@"secret"]]; 

    NSString *photoCount = [photo objectForKey:@"photos"]; 
    NSDictionary *title = [photo objectForKey:@"title"]; 
    NSString *itemTitle = [title objectForKey:@"_content"]; 
    TTLauncherItem *itemMenu = [[[TTLauncherItem alloc] initWithTitle:itemTitle 
                   image:iconURLString 
                    URL:nil 
                  canDelete:NO] autorelease]; 
    itemMenu.badgeValue = photoCount; 

    [itemArray addObject:itemMenu]; 
    int value = [countPage intValue]; 
    countPage = [NSNumber numberWithInt:value + 1]; 
    if (countPage == [NSNumber numberWithInt:9]){ 
     countPage = [NSNumber numberWithInt:0]; 
     [pageArray addObject:itemArray]; 
     itemArray = [[NSMutableArray alloc] init]; 


    } 

} 
[pageArray addObject:itemArray]; 

launcherView = [[TTLauncherView alloc] initWithFrame:self.view.bounds]; 
launcherView.backgroundColor = [UIColor blackColor]; 
launcherView.delegate = self; 
launcherView.columnCount = 3;  
launcherView.persistenceMode = TTLauncherPersistenceModeNone;  
launcherView.pages = pageArray;  
[self.view addSubview:launcherView];  

}
