iphone UITextView设置行间距 [英] iphone UITextView set line spacing

问题描述

如何在UITextView中增加行空间，使其在iPhone中看起来像Notes应用程序？

How can I increase line space in UITextView so that it looks like "Notes" app in iPhone?

推荐答案

现在好了在iOS6上，有一种可能性，使用NSParagraphStyle，但它的记录很少，似乎很少工作。

Well now on iOS6, there is a possibility, using NSParagraphStyle, but it is very poorly documented and seems to work seldomly.

我目前正在解决这个问题：

im currently working about it like this:

UITextView *lab = [LocalTexts objectAtIndex:j];

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.lineHeightMultiple = 50.0f;
paragraphStyle.maximumLineHeight = 50.0f;
paragraphStyle.minimumLineHeight = 50.0f;

NSString *string = lab.text;
NSDictionary *ats = @{
NSFontAttributeName : [UIFont fontWithName:@"DIN Medium" size:16.0f],
NSParagraphStyleAttributeName : paragraphStyle, 
};

lab.attributedText = [[NSAttributedString alloc] initWithString:string attributes:ats];

问题是当你设置字体时，行高停止工作..非常奇怪，避风港' t找到了它的修复程序。

Problem is that when you set the font, the line height stops working.. very odd, haven't found a fix for it yet.

你也可以创建一个自定义的Attributed CoreText视图......但它的技术性更强一点，你可以找到它的演示方法已完成此处

Also you can create a custom Attributed CoreText view... but its a bit more technical, you can find a demo of how it is done here
