Can json parse jsp data in ios?
1. First, create a new project (be careful not to choose the ARC mechanism) and add the following controls:
2. the code in the 2.ViewController.h file:
(1) Use TouchJSon parsing method: (package to be imported: # import "TouchJSON/JSON/cjsondeserializer.h")
# Import? & ltui kit/ui kit . h & gt； ?
@ Interface? ViewController？ :? UIViewController？
@ Property? (reserved,? Non-atomic)? IBOutlet？ UITextView？ * txtView？
-? (i action) btnpresstouchson: (id) sender; ?
-? (i action) btnpressbjson: (id) sender; ?
-? (I action)btnpressios 5 JSON:(id) sender; ?
-? (i action) btnpresssjsonkit: (id) sender; ?
@end？
3. the main code in the 3.ViewController.m file:
(1) Use TouchJSon parsing method: (package to be imported: # import "TouchJSON/JSON/cjsondeserializer.h")
//Analyze the weather in Beijing with TouchJson?
-? (i action) btnpresstouchson: (id) Sender? {?
//get the API interface?
NSURL？ * Website? =? 【NSURL？ URL with string:@ "/data/ 10 10 10 100 . html "]； ?
//Define a NSError object to capture error information?
NSError？ * error; ?
NSString？ *jsonString？ =? 【NSString？ stringwithcontentsourl:URL？ Code: NSUTF8StringEncoding? Error: & Error]; ?
NSLog(@ " JSON string-& gt； %@ "，JSON string)； ?
//Store the parsed content in a dictionary, with the encoding format of UTF8, so as to prevent garbled codes when fetching values?
NSDictionary？ *rootDic？ =? 【【CJSONDeserializer？ Deserializer] Deserialization: [jsonString? data using encoding:nsu TF 8 string encoding]？ Error: & Error]; ?
//Because the returned Json file has two layers, go to the second layer and put it in the dictionary?
NSDictionary？ *weatherInfo？ =? 【rootDic？ objectForKey:@ " weather info "]； ?
NSLog(@ " weather info-& gt； %@ "，weather info)； ?
//Print by value?
txtView.text？ =? 【NSString？ StringWithFormat:@ "What day is it today? %@? %@? %@? The weather condition in is:% @? %@?" ，【weatherInfo？ objectForKey:@"date_y"]，[weatherInfo？ objectForKey:@"week"]，[weatherInfo？ objectForKey:@"city"]，？ 【weatherInfo？ objectForKey:@ " weather 1 "]，？ 【weatherInfo？ objectForKey:@ " temp 1 "]]； ?
}?
