UIDatePicker非连续分钟

Question

我将我的UIDatepicker timeInterval设置为30分钟，因此它显示为30,60（重复）。我真的不希望它重复，只显示2个选项（如AM/PM）。有没有办法做到这一点，而不是从头开始创建它？

谢谢！

为什么不使用UIPicker呢？

UIPickerView *pick=[[UIPickerView alloc] initWithFrame:CGRectMake(300, datep.frame.origin.y, datep.frame.size.width, datep.frame.size.height)]; 
[pick setDelegate:self]; 
[pick setDataSource:self]; 
[pick setShowsSelectionIndicator:YES]; 
[self.view addSubview:pick]; 

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView{ 
return 3; 
} 
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component{ 
if(component==0){ 
    return 12; 
}else{ 
    return 2; 
} 

return 2; 
} 

- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component{ 
if(component==1){ 
    if(row==1) 
     return @"30"; 
    else 
     return @"00"; 
    } 
else if(component==0){ 
    return [NSString stringWithFormat:@"%d", row+1]; 
}else{ 
    if(row==1) 
     return @"AM"; 
    else 
     return @"PM"; 
    }  
} 

-(CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component{ 
return 50; 
} 

- (CGFloat)pickerView:(UIPickerView *)pickerView rowHeightForComponent:(NSInteger)component{ 
return 50; 
}
