我在我的應用程序中遇到了非常奇怪的問題,有一個部分我從服務器收集數據,作爲響應,我獲得了lat和long附近的餐館,通過使用這些拉特和長我得到每個距離當前用戶的位置,我已經應用排序像衣櫃遠離當前用戶位置收集的數據,everthing正常工作在我的結束但是每當客戶端在他的最後測試時,那麼排序不起作用。我在這裏附上了代碼。根據緯度和長度獲取錯誤的排序距離

[super viewDidLoad];
myDelegate= (AppDelegate *)[[UIApplication sharedApplication] delegate];
NSLog(@"Lat %f", [[myDelegate.myLocation objectForKey:@"LATITUDE"]floatValue]);
NSLog(@"Long %f",[[myDelegate.myLocation objectForKey:@"LONGITUDE"]floatValue]);
self.coordArray= [[NSMutableArray alloc]init];
// Do any additional setup after loading the view from its nib.
timer=[NSTimer scheduledTimerWithTimeInterval:(10.0) target:self selector:@selector(upateLocation) userInfo:nil repeats:YES];
float dist;
for (int i=0; i<[myDelegate.placeArray count]; i++) {
dist=(6371 * acos(cos(RADIANS_TO_DEGREES([[myDelegate.myLocation objectForKey:@"LATITUDE"]floatValue])) *
cos(RADIANS_TO_DEGREES([[[myDelegate.placeArray objectAtIndex:i] latitude] floatValue])) * cos(RADIANS_TO_DEGREES([[[myDelegate.placeArray objectAtIndex:i] longitude] floatValue]) - RADIANS_TO_DEGREES([[myDelegate.myLocation objectForKey:@"LONGITUDE"]floatValue])) + sin(RADIANS_TO_DEGREES([[myDelegate.myLocation objectForKey:@"LATITUDE"]floatValue])) * sin(RADIANS_TO_DEGREES([[[myDelegate.placeArray objectAtIndex:i] latitude] floatValue]))));
//int distVal=(int)dist;
distStr= [NSString stringWithFormat:@"%.2f",dist];
NSLog(@"new---%@",distStr);
[self.coordArray addObject:distStr];
}
NSMutableDictionary *tmpDict;
for (int i=0; i<[myDelegate.placeArray count]; i++) {
tmpDict = [[NSMutableDictionary alloc]initWithObjectsAndKeys:[[myDelegate.placeArray objectAtIndex:i] ids],@"contentId",[[myDelegate.placeArray objectAtIndex:i] restaurantname],@"contentTitle",//contentAdd

下面是對上述代碼的解釋。 1 - 有一個陣列(地方陣列),它具有所有經度和長度對應於每家餐館。 2 - 從這個數組中,通過使用Harvest方法,我得到以km爲單位的距離,然後將這些距離添加到名爲(coordArray)的另一個數組中。 3然後創建上,我已經申請最終陣列即(dataArray中的排序
這工作得很好,在我的結束,但不工作,一旦我對iPhone 5進行測試 任何人都可以建議我什麼是錯與此。代碼我不是歌廳
請幫我從這個並感謝所有給你的寶貴時間
感謝阿努普,它的工作,在我們的終端,因爲它是工作ealriaer但在客戶端這不是working.It一些值正確地排序,但在某些價值觀是不work.Can請你建議。 –
@FlexsinFlex由於排序是基於距離。仔細檢查它的值。我的建議是刪除許多詳細的步驟,以提高可讀性和易於調試。由於您有用於存儲的模型對象,因此可以將創建的字典移動到該類。然後你只需要添加距離來創建tmpDict(由模型形成)。 – Anupdas
