[英]How to access the array dictionary values from mutableArray
如何從鍵值數組的字典數組中獲取值。
-(void)viewDidLoad{
listMutableArray =[[NSMutableArray alloc] initWithObjects:[NSDictionary dictionaryWithObject:[NSArray
arrayWithObjects:@"kiran",@"1234512345",@"IN", nil] forKey:[NSArray
arrayWithObjects:@"name",@"phone",@"location", nil]],nil];
}
//將值設置為tableview單元格。
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
// Custom cell declaration completed.
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil){
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
NSLog(@"Value of name %@", [[listMutableArray objectAtIndex:indexPath.row] objectForKey:@"name"]);
}
當從返回nil對象的可變數組的字典數組中打印名稱密鑰對時。
如何從可變數組獲取名稱電話位置值。
您的數組格式錯誤這樣的Form數組
NSMutableArray *listMutableArray =[[NSMutableArray alloc] initWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:@"kiran",@"name",@"1234512345",@"phone",@"IN",@"location", nil], nil];
NSLog(@"%@",listMutableArray);
並在cellForRowAtIndexPath
嘗試打印
NSLog(@"Value of name %@", [[listMutableArray objectAtIndex:indexPath.row] objectForKey:@"name"]);
您想在數組流中添加多個對象,如下代碼
NSDictionary *dict = @{
@"name": @"kiran",
@"phone": @"1234512345",
@"location": @"IN"
};
NSDictionary *dict1 = @{
@"name": @"Bala",
@"phone": @"12345123",
@"location": @"OUT"
};
NSDictionary *dict2 = @{
@"name": @"Sri",
@"phone": @"898989898",
@"location": @"IN"
};
NSMutableArray *listMutableArray =[[NSMutableArray alloc] initWithObjects:dict,dict1,dict2, nil];
您的代碼正在創建一個包含單個字典的數組,該字典具有作為鍵和值的數組。 我認為您想要一系列詞典; 例如:
listMutableArray = [NSMutableArray new];
[listMutableArray addObject:@{
@"name": @"kiran",
@"phone": @"1234512345",
@"location": @"IN"
}];
We get all NSDictionary response add in jsonResult(NSDictionary) and create globel (arrData)NSMutableArray.
arrData = [NSMutableArray new];
for (int i =0; i < [jsonResult count]; i++)
{
NSString *string = [NSString stringWithFormat:@"%d",i];
[arrData addObject:[NSMutableDictionary dictionaryWithObjectsAndKeys:[[jsonResult valueForKey:string] valueForKey:@"name"],@"name",[[jsonResult valueForKey:string] valueForKey:@"phone"],@"phone",[[jsonResult valueForKey:string] valueForKey:@"location"],@"location",nil]];
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
// Custom cell declaration completed.
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil){
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
NSLog(@"Value of name %@", [[arrData objectAtIndex:indexPath.row] valueForKey:@"name"]);
return cell;
}
NSArray *dictionary = @[
@{
@"Source_lat": @"28.6287",
@"Source_lon": @"77.3208",
@"Detail":@{
@"Address": @"NOIDA",
@"Region": @"NCR",
},
},
@{
@"Source_lat": @"28.628454",
@"Source_lon": @"77.376945",
}
];
