如何更改字体系列＆amp; iOS中的textview风格？

Question

我想改变字体样式＆amp; UITextView的家人。实际上，我会从选择器中选择字体系列，然后更改UITextView的字体系列。请告诉我该怎么做？

Answer 1

在这个假设中，我提交了我的答案，如果有任何疑问，请自定义其他

-(void)pickerView:(UIPickerView *)pickerView didSelectRow:
 (NSInteger)row inComponent:(NSInteger)component{
   // here you can get index for selected Row
   [yourTextView setText:[pickerArray objectAtIndex:row]];

    [yourTextView setFont:[UIFont fontWithName:@"Helvetica Neue" size:18.0f]];
 yourTextView.textColor = [UIColor whiteColor];
 }

Answer 2

尝试此选项以在选择器中显示系列字体名称

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{
UILabel* labelFontName = (UILabel*)view;
if (!labelFontName ){
    labelFontName = [[UILabel alloc] init];
    labelFontName .adjustsFontSizeToFitWidth = YES;
    labelFontName .TextAlignment = NSTextAlignmentCenter;
    labelFontName .font = [UIFont fontWithName:@"Arial" size:18];
}
NSString *stringForTitle= [NSString stringWithFormat:@"%@",   [arrayOfYourPickerElements objectAtIndex:row]];// Fill the label text here
labelFontName .text = stringForTitle;
return labelFontName ;
}

选择fontName后

：

 yourTextView.font = [UIFont fontWithName:label size:17];
