NSTextAlignment：无法从objective-c转换为swift

Question

我对我非常失望，但我无法将此代码从objective-c转换为swift。 ： - （

是的，有人能帮帮我吗？我不知道并且发现Google没有没有。经过一段沮丧的时间后，我求求你的帮助; - ）

目标-c-代码:(看起来很简单[grrrrr]）

-(void)setParagraphAlignment:(NSTextAlignment)newAlignment{
    NSRange selectedRange = [_textView selectedRange];
    NSMutableParagraphStyle *newParagraphStyle = [[NSMutableParagraphStyle alloc] init];
    [newParagraphStyle setAlignment:newAlignment];

    NSDictionary *dict = @{NSParagraphStyleAttributeName: newParagraphStyle};
    [textView.textStorage beginEditing];
    [textView.textStorage setAttributes:dict range:selectedRange];
    [textView.textStorage endEditing];
}

唯一可以改变的是： - （

textView.textStorage .beginEditing()
textView.textStorage .endEditing()

Answer 1

func selectParagraphAlignment(newAlignment:NSTextAlignment) {
    var selectedRange = textView.selectedRange
    var newParagraphStyle = NSMutableParagraphStyle()
    newParagraphStyle.alignment = newAlignment

    var dict = [NSParagraphStyleAttributeName: newParagraphStyle]
    textView.textStorage.beginEditing()
    textView.textStorage.setAttributes(dict, range: selectedRange)
    textView.textStorage.endEditing()

}

希望这会有所帮助：D
