可以在iOS7中更改datePicker的字体颜色吗？ [英] can I change the font color of the datePicker in iOS7?

问题描述

刚刚下载了我的xcode 5的副本，并且想知道是否有人知道如何更改日期选择器中字体的颜色或大小？

解决方案（UIView *）pickerView：（UIPiewView *）pickerView viewForRow :( NSInteger）row forComponent：（NSInteger）component reusingView：（UIView *）view {

UILabel * label = [[UILabel alloc] initWithFrame：CGRectMake（0，0，pickerView.frame.size.width，44）];
label.backgroundColor = [UIColor grayColor];
label.textColor = [UIColor whiteColor];
label.font = [UIFont fontWithName：@HelveticaNeue-Boldsize：18];
label.text = [NSString stringWithFormat：@％d，row + 1];
返回标签;
}

//组件数量
- （NSInteger）numberOfComponentsInPickerView：（UIPickerView *）pickerView {
return 1;
}

//组件中的行数
- （NSInteger）pickerView：（UIPickerView *）pickerView numberOfRowsInComponent：（NSInteger）component {
return 6;
}

just downloaded my copy of xcode 5 and was wondering if anyone knows how I can change the color or size of the font in the date picker?

解决方案

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, pickerView.frame.size.width, 44)];
label.backgroundColor = [UIColor grayColor];
label.textColor = [UIColor whiteColor];
label.font = [UIFont fontWithName:@"HelveticaNeue-Bold" size:18];
label.text = [NSString stringWithFormat:@" %d", row+1];
return label;    
}

// number Of Components
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView{
return 1;
}

// number Of Rows In Component
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:   (NSInteger)component{
return 6;
}
