我正在尝试从我的解析类中检索下一组解析数据,但我完全不知道如何实现我想要做的事情。
示例用户从提示#1开始,然后按下,然后显示提示#2,依此类推。
我在“下一步”按钮上有一个解析查询,它应该将解析中的下一个提示加载到名为tipBody的UILabel中,并将下一个连续提示号加载到我的tipNumber标签中。
- (IBAction)nextTipAction:(id)sender
{
[ProgressHUD show:@"Loading Next Tip"];
//Get Current Comments//
__weak typeof (self) weakSelf = self;
PFQuery *query = [PFQuery queryWithClassName:@"Archive"];
[query whereKey:@"body" equalTo:@"tipNumber"];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (!error)
{
weakSelf.tipNumberLabel.text =[NSString stringWithFormat:@"Tip Number: %ld", [[weakSelf.currentTip objectForKey:@"tipNumber"] integerValue]];
[self.currentTip incrementKey:@"tipNumber" byAmount:@+1];
[ProgressHUD dismiss];
}
else
{
[ProgressHUD dismiss];
[ProgressHUD showError:@"Sorry! Unable to load Tips"];
// Log details of the failure
NSLog(@"Error: %@ %@", error, [error userInfo]);
}
}];
}
非常感谢任何帮助!谢谢!

检查您的代码如下。
String number;
people.moveToFirst();
do {
String name = people.getString(indexName);
number = people.getString(indexNumber);
// for(int j=0;j<=j_count;j++){
if (some_num.contains(number)){
// do nothing
}
else{
Log.e("num",number);
//}
j_count++;
// Do work...
} while (people.moveToNext());
}
