如何在iphone

Question

閱讀控制檯的JSON值我已經在控制檯下面的JSON值：

{"TokenID":"kuiHigen21","isError":false,"ErrorMessage":"","Result":[{"UserId":"153","FirstName":"Rocky","LastName":"Yadav","Email":"rocky@itg.com","ProfileImage":null,"ThumbnailImage":null,"DeviceInfoId":"12"}],"ErrorCode":900} 

這是我的服務器API：@「http://192.168.0.68:91/JourneyMapperAPI?RequestType =登錄「 // api需要5個參數。 當我發佈數據到服務器的api值發佈到服務器，我得到了以json格式的上述響應。

我想解析上述JSON值，我得到的響應和保存在sqlite數據庫。

我這樣做代碼分析上面的JSON值：

-(void)connectionDidFinishLoadingNSURLConnection *)connection 
{ 
    NSString *loginStatus = [[NSString alloc] initWithBytes: [webData mutableBytes] lengthwebData length] encoding:NSUTF8StringEncoding];  
    NSLog(@"%@",loginStatus); 

self.webData = nil; 

     SBJSON *parser =[[SBJSON alloc]init]; 

    NSURLRequest *request = [NSURLRequest requestWithURLNSURL URLWithString"http://192.168.0.68:91/JourneyMapperAPI?RequestType=Login.json"]]; 

     NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 

    // Get JSON as a NSString from NSData response 

NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]; 

    //NSDictionary *object = [parser objectWithString:json_string error:nil]; 
    // parse the JSON response into an object 
// Here we're using NSArray since we're parsing an array of JSON status objects 

NSArray *statuses = [parser objectWithString:json_string error:nil];  


for (NSDictionary *status in statuses) 
{  
// You can retrieve individual values using objectForKey on the status NSDictionary 
    // This will print the tweet and username to the console 

NSLog(@"%@ - %@", [status objectForKey"Login"],[status objectForKey"LoginKey"]); 

    [connection release]; [webData release]; 

}

可以將此保存到一個模型類的幫助數據庫，結果

NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]; 

NSDictionary *result = [json_string JSONValue]; 
NSArray *values = [result objectForKey:@"Result"]; 
NSMutableArray *results = [[NSMutableArray alloc] init]; 

for (int index = 0; index<[values count]; index++) { 
    NSMutableDictionary * value = [values objectAtIndex:index]; 
    Result * result = [[Result alloc] init]; 
    result.UserId = [value objectForKey:@"UserId"]; 
    result. FirstName = [value objectForKey:@"FirstName"]; 
    ... 

    [results addObject:result]; 
    [result release]; 
} 

使用結果的陣列將其保存到數據庫中。

for (int index = 0; index<[results count]; index++) { 
    Result * result = [results objectAtIndex:index]; 

    //save the object variables to database here 
}

你應該檢查出一些JSON解析器的，我個人最喜歡的是json-framework。當您已經包含在你的項目中，你有你的JSON響應從服務器其中之一：

// Get JSON as a NSString from NSData response 

NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding]; 

NSDictionary *result = [json_string JSONValue]; 
NSArray *statuses = [result objectForKey:@"Result"]; 

將返回搜索結果的數組（其中數組中的每個對象是一個NSDictionary）。
