我正在做 json 解析应用程序。其中没有关于解析的问题。我有列表直到type="0"。但是type="1"有描述。所有“列表”以及“描述”都已正确设置。
{"pageid":"5824","title":"Sms Collection","type":"0","desc":"Friendship SMS:$@|5825|@$:4cing.com/mobile_app/uploads/pageicon/friendship.png;Love SMS:$@|5826|@$:4cing.com/mobile_app/uploads/pageicon/Love.png;Miss U SMS:$@|5827|@$:4cing.com/mobile_app/uploads/pageicon/missu.png;Funny SMS:$@|5828|@$:4cing.com/mobile_app/uploads/pageicon/funny.png;Valentine SMS:$@|5829|@$:4cing.com/mobile_app/uploads/pageicon/valantine.png;Adult SMS:$@|5830|@$:4cing.com/mobile_app/uploads/pageicon/adult.png;Anniversary SMS:$@|5832|@$:4cing.com/mobile_app/uploads/pageicon/anniversary.png;Birthday SMS:$@|5833|@$:4cing.com/mobile_app/uploads/pageicon/birthday.png;Break up SMS:$@|5834|@$:4cing.com/mobile_app/uploads/pageicon/Breakup.png;Broken Heart SMS:$@|5835|@$:4cing.com/mobile_app/uploads/pageicon/heartbroken.png;Christmas SMS:$@|5836|@$:4cing.com/mobile_app/uploads/pageicon/Christmas.png;Exam SMS:$@|5837|@$:4cing.com/mobile_app/uploads/pageicon/exam.png;Flirt SMS:$@|5838|@$:4cing.com/mobile_app/uploads/pageicon/flirtsms.png;Good Luck SMS:$@|5839|@$:4cing.com/mobile_app/uploads/pageicon/goodluck.png;Good Morning SMS:$@|5840|@$:4cing.com/mobile_app/uploads/pageicon/goodmornig.png;Good Night SMS:$@|5841|@$:4cing.com/mobile_app/uploads/pageicon/goodnight.png;Insult SMS:$@|5842|@$:4cing.com/mobile_app/uploads/pageicon/inseart.png;Pashto SMS:$@|5843|@$:4cing.com/mobile_app/uploads/pageicon/pashto.png;Poetry SMS:$@|5844|@$:4cing.com/mobile_app/uploads/pageicon/poetry.png;Sardar SMS:$@|5845|@$:4cing.com/mobile_app/uploads/pageicon/sardar.png;Santa Banta SMS:$@|5846|@$:4cing.com/mobile_app/uploads/pageicon/santabanta.png;Smile SMS:$@|5847|@$:4cing.com/mobile_app/uploads/pageicon/smile.png;Sorry SMS:$@|5848|@$:4cing.com/mobile_app/uploads/pageicon/sorry.png;Chanakya SMS:$@|5849|@$:4cing.com/mobile_app/uploads/pageicon/chanakya.png;","cache":"1","Nexturl":"5825","prevurl":"0","bckurl":"0"}
当应用程序启动时（type="0"），这是包含上述数据的第一个列表。
Onclick友谊短信单元格我得到（类型=“0”）这个数据。

最后，对于“Do not lie,Do not che...”的屏幕点击有 (type="1") 所以描述显示为
我在后台过程中遇到问题，我必须使用类似于前一页的pageid的prevurl来实现后台功能
这是我为后台功能所做的代码，
-(IBAction)btnBackClicked:(id)sender
{
int Type;
NSMutableDictionary *tempDict1;
for(int i=0;i<[test.JsonPageList count];i++)
{
tempDict1 = [[NSMutableDictionary alloc]init];
tempDict1 = (NSMutableDictionary *)[test.JsonPageList objectAtIndex:i];
NSLog(@"pageid is.....%d",[[tempDict1 valueForKey:@"pageid"] intValue]);
if ([[tempDict1 valueForKey:@"pageid"] intValue])
{
Type = [[tempDict1 valueForKey:@"type"] intValue];
if (Type == 0)
{
NSArray *arr=[[tempDict1 valueForKey:@"desc"] componentsSeparatedByString:@";"];
NSString *subStar = @"|@$:";
NSString *sub=@":$@|";
[test.arrTitle removeAllObjects];
[test.arrnew removeAllObjects];
[test.arrId removeAllObjects];
[test.arrImages removeAllObjects];
for (int i=0; i<[arr count]-1; i++)
{
[test.arrTitle addObject:[[arr objectAtIndex:i] substringToIndex:NSMaxRange([[arr objectAtIndex:i] rangeOfString:sub])-4]];
[test.arrnew addObject:[[arr objectAtIndex:i] substringFromIndex:NSMaxRange([[arr objectAtIndex:i] rangeOfString:sub])]];
[test.arrId addObject:[[test.arrnew objectAtIndex:i] substringToIndex:NSMaxRange([[test.arrnew objectAtIndex:i] rangeOfString:subStar])-4]];
[test.arrImages addObject:[[arr objectAtIndex:i] substringFromIndex:NSMaxRange([[arr objectAtIndex:i] rangeOfString:subStar])]];
}
[tbl_withData reloadData];
}
}
}
}
这是解析的代码
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
[connection release];
NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
if ([[NSUserDefaults standardUserDefaults] boolForKey:@"SecondTime"])
{
[self saveData:responseData toFile:@"SMSCollection.txt"];
results = [responseString JSONValue];
JsonPageList = [results objectForKey:@"page"];
desc = [[NSMutableArray alloc] init];
for (NSString * strName in results)
{
JsonPageList = [results objectForKey:strName];
dictHash = [[NSMutableDictionary alloc] init];
[dictHash setObject:JsonPageList forKey:@"JsonPageList"];
for (int i = 0; i < [JsonPageList count]; i++)
{
[desc addObject:[[JsonPageList objectAtIndex:i] valueForKey:TAG_DESC]];
int PAGEID = [[NSString stringWithFormat:@"%@",[[JsonPageList objectAtIndex:i] valueForKey:@"pageid"]] intValue];
[self displayPage:PAGEID];
}
}
}
[responseString release];
}
-(void) displayPage:(int)pageID
{
page.pageid = pageID;
if (page.type == PAGE_TYPE_MENU)
{
NSString *desc1=[desc objectAtIndex:0];
NSArray *arr=[desc1 componentsSeparatedByString:@";"];
NSString *subStar = @"|@$:";
NSString *sub=@":$@|";

arrId=[[NSMutableArray alloc]init];
for (int i=0; i<[arr count]-1; i++)
{

[arrImages addObject:[[arr objectAtIndex:i] substringFromIndex:NSMaxRange([[arr objectAtIndex:i] rangeOfString:subStar])]];
}
}
else if (page.type == PAGE_TYPE_CONTENT)
{
NSLog(@"CURR title:- %@\n & desc:- %@",page.title1 ,page.desc);
UITextView *TextView = [[UITextView alloc] init];
TextView.text = page.title1;
UILabel *lblcurrentPage = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 300)];
lblcurrentPage.backgroundColor = [UIColor whiteColor];
lblcurrentPage.textColor = [UIColor blackColor];
lblcurrentPage.text = page.desc;
}
}
帮我解决这个问题。
