我想只显示每个日期的第一条记录.
那么,任何人都可以帮助我吗？
我必须在标签中显示粗体文字
最佳答案 如果您只想要特定日期的第一个对象,您可以尝试这样做.
NSArray *dataPoints = [tideDic objectForKey:@"dataPoints"];
NSMutableArray *firstObjects = [[NSMutableArray alloc] init];
NSMutableArray *dayArray = [[NSMutableArray alloc] init];
for (NSDictionary *dic in dataPoints) {
NSString *locatationTime = [dic objectForKey:@"Localtime"];
NSString *dateOnly = [[locatationTime componentsSeparatedByString:@" "] firstObject];
if (![dayArray containsObject:dateOnly]) {
[dayArray addObject:dateOnly];
[firstObjects addObject:dic];
}
}
