如何获得阵列内的NSDictionary

我是iOS的新手，我面临着在数组中获取字典的问题。如何获得阵列内的NSDictionary

数组是这样的：

[{"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"}]

我用这样的代码

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); 
}

，但它给我只能第一个值这是0th指数。

您可以像这样解析字典'for yourArray中的字典'{'dict'是您的解析字典} – PiyushRathi

@PiyushRathi但它只显示值。 – Muju

我们在这里申请循环，这将迭代直到数组中的最后一个字典。 – PiyushRathi

您可以使用for循环的，如果你想迭代所有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); 
    }

如果你想在特定的指数以获得Dictionary：

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

我有10个对象在我的array.But当我用你的代码Dict值打印只有5个键/值对。只有一个对象。 – Muju

@Muju你使用For循环？ – Dalvik

@Muju cab你发布了你的实际代码？ – Dalvik

你检查，如果你的JSON字符串结构良好？ “\”用户1 \“：{\”Iden \“：4，\”nID \“：1}，\”user2 \“：{\”Iden \“：5，\” 与“\” like： “nID \”：1}}

@MararIbragimov它形成得很好。 – Muju

我的意思是它应该被javascript转义： –

@“[{\”CheckPointId \“：41，\”AId \“：4，\”CheckPoint \“：\”检查所有设备和负载附近维护的SOP \ “，”MId“：41，”MethodOfMeasure“：\”Visual Inspection \“}，{\”CheckPointId \“：42，\”AId \“：4，\”CheckPoint \“：\”Check单线图（SLD）在面板区域\“，\”MId \“：42，\”MethodOfMeasure \“：\”Visual Inspection \“}，{\”CheckPointId \“：43，\”AId \ ：4，\“CheckPoint \”：\“检查危险通知在现场维护\”，\“MId \”：43，\“MethodOfMeasure \”：\“Visual Inspection \”}]“ –
