Question

我有eachRow.split(',')。它有8个对象。每个对象都有5个键值对，如下所示

NSMutableArray

这个＆＃34;出席率＆＃34;另一本字典。就像这样

{
    "Attendance": {}, 
    "Shift": {}, 
    "DayType": {}, 
    "DayTypes": null, 
    "TotalOvertimeString": "06:00"
},

我想要做的是在此数组中找到这个确切的日期值是否可用"Attendance": { "AttendanceCode": 5058, "Date": "2016-02-01T00:00:00", "EmployeeCode": 2941, "ShiftCode": 1, "DayTypeCode": 1, "Expected": true, "Midnight": false, "Present": true, "InTime": "2016-02-01T08:00:00", "InTimeString": "08:00", "OutTime": "2016-02-01T20:00:00", "OutTimeString": "20:00", "OutDate": "2016-02-01T00:00:00", "InTime2": "1901-01-01T00:00:00", "InTime2String": "00:00", "InDate2": "1901-01-01T00:00:00", "OutTime2": "1901-01-01T00:00:00", "OutTime2String": "00:00", "OutDate2": "1901-01-01T00:00:00", "ApprovedOutTimeUsed": 0, "ApprovedOutTime": "1901-01-01T00:00:00", "Late": 0, "LateString": "00:00", "InLate": 0, "InLateString": "00:00", "MidLate": 0, "MidLateString": "", "OutLate": 0, "OutLateString": "00:00", "InOvertime": 0, "InOvertimeString": "", "OvertimeRate1": 6, "OvertimeRate1String": "06:00", "OvertimeRate1Approved": 0, "OvertimeRate1ApprovedString": "00:00", "OvertimeRate2": 0, "OvertimeRate2String": "00:00", "OvertimeRate2Approved": 0, "OvertimeRate2ApprovedString": "00:00", "OvertimeRate3": 0, "OvertimeRate3String": "00:00", "OvertimeRate3Approved": 0, "OvertimeRate3ApprovedString": "00:00", "OvertimeRate4": 0, "OvertimeRate4String": "00:00", "OvertimeRate4Approved": 0, "OvertimeRate4ApprovedString": "00:00", "OvertimeRate5": 0, "OvertimeRate5String": "00:00", "OvertimeRate5Approved": 0, "OvertimeRate5ApprovedString": "00:00", "OvertimeRate6": 0, "OvertimeRate6String": "00:00", "OvertimeRate6Approved": 0, "OvertimeRate6ApprovedString": "00:00", "OvertimeApprovalDone": false, "Lieu": false, "LieuFirstTaken": false, "LieuSecondTaken": false, "LieuPayment": 0, "DayOff": false, "DayOffTaken": false, "LeaveTypeCode": 0, "LeaveAmount": 0, "LeaveTypeCode2": 0, "LeaveAmount2": 0, "ShortLeaveAmount": 0, "Premium": 0, "PremiumString": "00:00", "PremiumApproved": 0, "PremiumApprovedString": "00:00", "Missing": 0, "MissingString": "00:00", "ClockNumber": 0, "SectionCode": 0, "WorkHours": 0, "PeriodWorked": 0, "WorkHrs": 0, "Remarks": "uuuuuuuuuuuuuuus", "Deleted": false, "Status": true, "CreatedBy": 0, "CreatedDate": "1901-01-01T00:00:00", "UpdatedBy": 9, "UpdatedDate": "2016-01-13T22:48:03.737", "DeletedBy": 0, "DeletedDate": "1901-01-01T00:00:00" },如何在此数组中搜索此日期是否可用？请帮帮我。

Answer 1

对于这种嵌套结构，您可以使用valueForKeyPath代替valueForKey。第一个对象是字典。

NSDictionary *dict = @{
    @"Attendance": @{...,@"Date": @"2016-02-01T00:00:00",....}, 
    @"Shift": @{}, 
    @"DayType": @{}, 
    @"TotalOvertimeString": @"06:00"
};

使用以下代码行：

[[dict valueForKeyPath:@"Attendance.Date"] isEqualToString:@"your date"]

Answer 2

尝试以下代码行 [arrray valueForKey @“Attendance”] valueForKey @“Date”] isEqualToString：@“2016-02-01T00：00：00”]

希望这会对你有所帮助。

Answer 3

您可以从中获取数据并按以下方式进行比较。

NSMutableArray *array = @[];//Array of dictionaries
NSDate *dateToCompare = [NSDate date];//Any date you want to compare
for (NSDictionary *dictionary in array) {
    NSDate *dateAttendance = dictionary[@"Attendance"][@"Date"];
    //Compare dates
    if ([dateToCompare isEqualToDate:dateAttendance]) {
        NSLog(@"Dates equal");
    }
}

如果两个日期都在NSString中，您可以使用

[dateToCompareString isEqualToString:dateAttendanceString]

Answer 4

我想你可以试试这个

([yourArray@[0] valueForKey@"Date"] compare:dateYouEntered == NSOrderedSame)

然后您输入的日期存在于yourArray

中

Answer 5

致力于@Muhammad Nabeel Arif回答。你只需要在你的NSMutableArray中迭代你的所有对象来获取数组中的所有日期。最后，您可以使用NSMutableArray的containsObject方法检查您的日期。

NSDate *dateToCompare = [NSDate date];//Any date you want to compare
NSMutableArray *allDates =[NSMutableArray alloc]init];
for (int i = 0; i<array.count; i++)
{
    NSMutableDictionary *dictionary = @{};//YOur data
    NSDate *dateAttendance = dictionary[@"Attendance"][@"Date"];//Compare dates
    [allDates addObject:dateAttendance];
}

if([allDates containsObject:dateToCompare])
{
// Do whatever if it exists
}else
   {
`// place your code here if its doesnt exist.`
   }

如果数组中存在anObject，

containsObject方法返回YES，否则返回NO。

希望它有所帮助。快乐的编码.. !!
