Как получить NSDictionary внутри массива

Question

Я новичок в iOS и сталкиваюсь с проблемой получения словаря внутри массива.

массив как это:

[{"CheckPointId":41,"AId":4,"CheckPoint":"Check SOP maintained near all equipments and loads","MId":41,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":42,"AId":4,"CheckPoint":"Check Single line diagram (SLD) is maintained in panel area","MId":42,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":43,"AId":4,"CheckPoint":"Check danger notices are maintained at site","MId":43,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":44,"AId":4,"CheckPoint":"Check Rubber mats are maintained infront of the electrical panels","MId":44,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":45,"AId":4,"CheckPoint":"Check the availibility of HT gloves","MId":45,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":46,"AId":4,"CheckPoint":"Check Treatment of Electric shock board is displayed","MId":46,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":47,"AId":4,"CheckPoint":"Check Total connected load details are displayed","MId":47,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":48,"AId":4,"CheckPoint":"Check LOTO is in practice ","MId":48,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":49,"AId":4,"CheckPoint":"Check for Lightning arrestor installed in terrace","MId":49,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":50,"AId":4,"CheckPoint":"Check APFC is maintaining power factor (0.99 - 1.00)","MId":50,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":51,"AId":4,"CheckPoint":"Check for history cards maintained near equipments","MId":51,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":52,"AId":4,"CheckPoint":"Check checklists are maintained up to date and duely signed by site incharge","MId":52,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":53,"AId":4,"CheckPoint":"Check for earthing provided to equipments","MId":53,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":54,"AId":4,"CheckPoint":"Check for exhaust mechansim in the equipment and load section","MId":54,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":55,"AId":4,"CheckPoint":"Check for fire extinguisher in the equipment area","MId":55,"MethodOfMeasure":"Visual Inspection"}] 

Я использовал код, как этот

NSString *string = [LoginResult valueForKey:@"text"]; 

NSData *data = [string dataUsingEncoding:NSUTF8StringEncoding]; 

NSArray *responsearry = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil]; 

for(NSDictionary *dict in responsearry) { 
    NSLog(@"----dict--%@",dict); 
} 

Но это дает мне только первое значение, которое на 0th индекс.

Вы можете использовать for Loop, если вы хотите, чтобы итерация все Dict:

NSArray *yourArray = [{"CheckPointId":41,"AId":4,"CheckPoint":"Check SOP maintained near all equipments and loads","MId":41,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":42,"AId":4,"CheckPoint":"Check Single line diagram (SLD) is maintained in panel area","MId":42,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":43,"AId":4,"CheckPoint":"Check danger notices are maintained at site","MId":43,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":44,"AId":4,"CheckPoint":"Check Rubber mats are maintained infront of the electrical panels","MId":44,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":45,"AId":4,"CheckPoint":"Check the availibility of HT gloves","MId":45,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":46,"AId":4,"CheckPoint":"Check Treatment of Electric shock board is displayed","MId":46,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":47,"AId":4,"CheckPoint":"Check Total connected load details are displayed","MId":47,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":48,"AId":4,"CheckPoint":"Check LOTO is in practice ","MId":48,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":49,"AId":4,"CheckPoint":"Check for Lightning arrestor installed in terrace","MId":49,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":50,"AId":4,"CheckPoint":"Check APFC is maintaining power factor (0.99 - 1.00)","MId":50,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":51,"AId":4,"CheckPoint":"Check for history cards maintained near equipments","MId":51,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":52,"AId":4,"CheckPoint":"Check checklists are maintained up to date and duely signed by site incharge","MId":52,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":53,"AId":4,"CheckPoint":"Check for earthing provided to equipments","MId":53,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":54,"AId":4,"CheckPoint":"Check for exhaust mechansim in the equipment and load section","MId":54,"MethodOfMeasure":"Visual Inspection"},{"CheckPointId":55,"AId":4,"CheckPoint":"Check for fire extinguisher in the equipment area","MId":55,"MethodOfMeasure":"Visual Inspection"}]; 

    for(NSDictionary *dict in yourArray) 
    { 
      NSLog(@"----dict--%@",dict); 
    } 

Если вы хотите получить Dictionary в частности индекс:

int index = 1; 
    NSDictionary *dict = [yourArray objectAtIndex:index];

вы проверить, если ваш JSON строка хорошо сформирована? с "\" например: {\ "user1 \": {\ "Iden \": 4, \ "nID \": 1}, \ "user2 \": {\ "Iden \": 5, \ "nID \": 1}}
