2012-05-05 10:45:02.727 passingdata[63856:fb03] array : {
posts = {
Friday = (
{
GymClass = {
"CLASS-TYPE2" = "";
"CLASS_LEVEL" = "Intro/General";
"CLASS_TYPE" = "Muay Thai";
"DAY_OF_WEEK" = Friday;
TIME = "13:00 - 14:30";
};
}
);
Monday = (
{
GymClass = {
"CLASS-TYPE2" = "Fighters Training";
"CLASS_LEVEL" = "Fighters/Advanced/Intermediate";
"CLASS_TYPE" = "Muay Thai ";
"DAY_OF_WEEK" = Monday;
TIME = "09:30 - 11:00";
};
}, ......
with this code I can get friday's "Friday" and display the GymClass info "GymClass" on my table
使用此代码，我可以获得星期五的“星期五”并在我的桌子上显示 GymClass 信息“GymClass”
- (void)fetchedData:(NSData *)responseData { //parse out the json data
searchResults2 = [NSMutableArray arrayWithCapacity:10];
NSError* error;
NSDictionary* dictionary = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
NSLog(@"array : %@",dictionary);
NSArray *array = [[dictionary objectForKey:@"posts"] objectForKey:@"Friday"]; // retrieve that Day Gym Classes
if (array == nil) {
NSLog(@"Expected 'posts' array");
return;
}
for (NSDictionary *resultDict in array)
{
SearchResult *searchResult3;
searchResult3 = [self parseTrack:resultDict];
if (searchResult3 != nil) {
[searchResults2 addObject:searchResult3];
}
}
[self.tableView reloadData];
}
- (SearchResult *)parseTrack:(NSDictionary *)dictionary
{
SearchResult *searchResult1 = [[SearchResult alloc] init];
searchResult1.classType= [[dictionary objectForKey:@"GymClass"] objectForKey:@"CLASS_TYPE"];
searchResult1.classLevel= [[dictionary objectForKey:@"GymClass"] objectForKey:@"CLASS_LEVEL"];
NSLog(@"parse track = %@", searchResult1);
return searchResult1;
}
I can get the elements for one day but how do I get the Elements for every day (Mon,Tue...Sun)so i can display on my table by sections?
我可以获取一天的元素，但如何获取每天（周一、周二...周日）的元素，以便我可以按部分显示在我的桌子上？
thanks for your help..

Well in your code, you already are doing that:
那么在您的代码中，您已经在这样做了：
NSDictionary* dictionary = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
NSLog(@"array : %@",dictionary);
NSArray *array = [[dictionary objectForKey:@"posts"] objectForKey:@"Friday"]; // retrieve that Day Gym Classes
Wen can start from there to retrieve only the object posts:
Wen 可以从那里开始只检索对象posts：
NSDictionary* dictionary = [NSJSONSerialization JSONObjectWithData:responseData options:kNilOptions error:&error];
NSDictionary *posts = [dictionary objectForKey:@"posts"];
//Iterate over posts
for (NSArray *aDay in posts){
//Do something
NSLog(@"Array: %@", aDay);
}
Here, i am using Fast Enumeration to iterate over the dictionary, you should check this here.
在这里，我使用快速枚举来迭代字典，你应该在这里检查。
