大家好我所有关于时间选择的问题。我有 6个按钮来从_timeArray中选择时间。如果我选择btnTime1Clicked time1="02:00 AM"，如果我点击btnTime2Clicked，_timeArray应该大于凌晨02:00，应该是凌晨03:00，依此类推.TIA
_timeArray=[[NSMutableArray alloc]initWithObjects:@"12:00 AM",@"01:00 AM",@"02:00 AM",@"03:00 AM",@"04:00 AM",@"05:00 AM",@"06:00 AM",@"07:00 AM",@"08:00 AM",@"09:00 AM",@"10:00 AM",@"11:00 AM",@"12:00 PM",@"01:00 PM",@"02:00 PM",@"03:00 PM",@"04:00 PM",@"05:00 PM",@"06:00 PM",@"07:00 PM",@"08:00 PM",@"09:00 PM",@"10:00 PM",@"11:00 PM", nil];
- (IBAction)btnTime1Clicked:(id)sender {
time1=@"time1";
selectedpickerview=_timePickerView;
CGRect rect;
rect = [_timePickerView frame];
rect.origin.y = CGRectGetMaxY([UIScreen mainScreen].bounds)-320;
rect.size.height = 330;
_timePickerView.frame = rect;
[self.view addSubview:_timePickerView];
[_timePicker reloadAllComponents];
}
- (IBAction)btnTime2Clicked:(id)sender {
time2=@"time2";
selectedpickerview=_timePickerView;
CGRect rect;
rect = [_timePickerView frame];
rect.origin.y = CGRectGetMaxY([UIScreen mainScreen].bounds)-320;
rect.size.height = 330;
_timePickerView.frame = rect;
[self.view addSubview:_timePickerView];
[_timePicker reloadAllComponents];
}
