        NSLog(@" the status is %@", _status);




     i tried everything to get to the solution but no luck . 
     Please help .

Answer 1

尝试下一步：

NSDictionjary *yourJSON = [json objectForKey:@"ssoSummaryVOMap"];
id object = [yourJSON objectForKey:@"41178"];

Answer 2

很容易就可以获得值使用代码..

// ssoSummaryVOMap key denotes a parent dictionary 
NSDictionjary *yourJSON = [json objectForKey:@"ssoSummaryVOMap"];
// same 41178 key also denotes a dictionary which is sub dict of previous  
NSDictionjary *subDict = [yourJSON objectForKey:@"41178"];
// you can easily get the particular value now
NSString *value = [subDict objectForKey:@"aliasName"];
NSLog(@"response = %@",value);

快乐的编码..

Answer 3

NSArray *array = @[@{@"Key1" : @"Value1"}, @{@"Key2" : @"Value2"}, @{@"Key3" : @"Value3"}];
for (NSDictionary *dict in array) {
    NSLog(@"%@", dict.allKeys);
    for (NSString *key in dict.keyEnumerator) {
        NSLog(@"Key: %@, Value %@", key, dict[key]);
    }
}

Answer 4

重写这些行

sqlalchemy.exc.UnboundExecutionError: Could not locate a bind configured on mapper Mapper|Question|question or this Session

这样的事情......

NSArray* info = [json objectForKey:@"ssoSummaryVOMap"];
NSLog(@" ssoSummaryVOMap%@", info);

for(int i=0; i<info.count; i++)
{
    NSMutableDictionary * requestId= [[NSMutableDictionary alloc]init];
    requestId = [info objectAtIndex:i];
}

请注意，您应该添加一些感知检查代码。
