【问题描述】:
我正在尝试构建分组剖视图。我想将数组设置为字典中的对象,但我遇到了空数组问题。 这甚至可能吗????有什么诀窍吗????
#import "RootViewController.h"
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
// Get the specific Node for this row.
Nodes *nodes = (Nodes *)[nodesMArray objectAtIndex:indexPath.row];
// Create the Details View Controller and initialize it.
nodesDetailView *viewController = [[nodesDetailView alloc] initWithStyle:UITableViewStyleGrouped ];
[[self navigationController] pushViewController:viewController animated:YES];
// Set the title of the view to the nodes name
viewController.title = [nodes computer_name];
//Information
//Network Data
viewController.ipaddress= [nodes ipaddress];
viewController.subnet_mask= [nodes subnet_mask];
viewController.gateway= [nodes gateway];
viewController.domain_name= [nodes domain_name];
}
#import "nodesDetailViewController. h
@interface nodesDetailView : UITableViewController{
//Network Data
NSString *ipaddress;
NSString *subnet_mask;
NSString *gateway;
NSString *domain_name;
//Grouped
NSMutableArray *Keys;
NSMutableDictionary *Contents;
}
@property (nonatomic, retain) NSMutableArray *Keys;
@property (nonatomic, retain) NSMutableDictionary *Contents;
@property (nonatomic, retain) NSString *ipaddress;
@property (nonatomic, retain) NSString *subnet_mask;
@property (nonatomic, retain) NSString *gateway;
@property (nonatomic, retain) NSString *domain_name;
@end
#import "nodesDetailViewController. m
@synthesize .......
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
NSMutableArray *keys = [[NSMutableArray alloc] init];
NSMutableDictionary *contents = [[NSMutableDictionary alloc] init];
NSString *network = @"Network Data";
NSString *product = @"Product Details";
//IS THIS POSSIBLE ??????? Because I get An Empty array
[contents setObject:[NSArray arrayWithObjects: ipaddress,subnet_mask, gateway, domain_name, nil] forKey:network];
return self;
}
提前致谢。

请把你的问题说清楚...
-
NSlog it and I get The content of arry is{ "General Information" = ( ); "网络数据" = ( ); "产品详情" = ( ); }
-
请在您访问此数组的位置添加代码。据我所知,您的字典中的数组很好,但您访问它的方式错误。
-
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSString *key = [[self sectionKeys] objectAtIndex:section]; NSArray *contents = [[self sectionContents] objectForKey:key];返回[内容计数]; }
