ios - 将 json 值分配给标签

Question

这里我有一些 json 代码。有 2 个 data.like

name1
name2
lap1
lap2

只有label1,label2显示值。 Label3,label4 没有显示值!

Answer 1

使用这个

NSArray *jsonObject;
jsonObject = @[@{@"Id1":@"mad",
                 @"people2":@"12",@"total2":@"20"},
               @{@"Id2":@"normal",
                 @"people3":@"13",@"total3":@"30"}];


NSData *jsonData = [NSJSONSerialization dataWithJSONObject:jsonObject options:NSJSONWritingPrettyPrinted error:nil];
NSError *error = nil;
NSArray *arr = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&error];

NSLog(@" JSON DATA \n  %@",arr);


for (int i = 0; i < arr.count; i++) {

    NSArray *keys = [[arr objectAtIndex:i] allKeys];
    NSLog(@"%@",[[arr objectAtIndex:i] valueForKey:[keys objectAtIndex:0]]);
    NSLog(@"%@",[[arr objectAtIndex:i] valueForKey:[keys objectAtIndex:1]]);
    NSLog(@"%@",[[arr objectAtIndex:i] valueForKey:[keys objectAtIndex:2]]);
    //assign your label here line yourLabel.text = [[arr objectAtIndex:i] valueForKey:[keys objectAtIndex:0]];
}

注意:它适用于具有 3 个键的字典
