如何獲得陣列內的NSDictionary

我是iOS的新手，我面臨着在數組中獲取字典的問題。如何獲得陣列內的NSDictionary

數組是這樣的：

[{"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"}]

我用這樣的代碼

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); 
}

，但它給我只能第一個值這是0th指數。

您可以像這樣解析字典'for yourArray中的字典'{'dict'是您的解析字典} – PiyushRathi

@PiyushRathi但它只顯示值。 – Muju

我們在這裏申請循環，這將迭代直到數組中的最後一個字典。 – PiyushRathi

您可以使用for循環的，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數以獲得Dictionary：

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

我有10個對象在我的array.But當我用你的代碼Dict值打印只有5個鍵/值對。只有一個對象。 – Muju

@Muju你使用For循環？ – Dalvik

@Muju cab你發佈了你的實際代碼？ – Dalvik

你檢查，如果你的JSON字符串結構良好？「\」用戶1 \「：{\」Iden \「：4，\」nID \「：1}，\」user2 \「：{\」Iden \「：5，\」與「\」 like：「nID \」：1}}

@MararIbragimov它形成得很好。 – Muju

我的意思是它應該被javascript轉義： –

@「[{\」CheckPointId \「：41，\」AId \「：4，\」CheckPoint \「：\」檢查所有設備和負載附近維護的SOP \ 「，」MId「：41，」MethodOfMeasure「：\」Visual Inspection \「}，{\」CheckPointId \「：42，\」AId \「：4，\」CheckPoint \「：\」Check單線圖（SLD）在面板區域\「，\」MId \「：42，\」MethodOfMeasure \「：\」Visual Inspection \「}，{\」CheckPointId \「：43，\」AId \ ：4，\「CheckPoint \」：\「檢查危險通知在現場維護\」，\「MId \」：43，\「MethodOfMeasure \」：\「Visual Inspection \」}]「 –
