UILabel文本ios之前和之后的多余空间 [英] UILabel extra spaces before and after text ios

问题描述

标签以纵向模式完美显示文字.
当设备从纵向旋转到横向或从横向旋转到纵向时，它也可以正常工作.

Label shows text perfectly in portrait mode.
It also works properly when device rotates from portrait to landscape or landscape to portrait.

但是当我以横向模式打开应用程序时，它会在文本前后显示多余的空格.

But when i open app in landscape mode it shows extra spaces before and after the text.

我用过NumberOfLines = 0和sizeToFit.
并尝试过

I have used NumberOfLines = 0 and sizeToFit.
and also tried

CGSize aSize = [self.label sizeThatFits:CGSizeMake(self.label.frame.size.width, CGFLOAT_MAX)];
self.label.frame = CGRectMake(self.label.frame.origin.x, self.label.frame.origin.y, self.label.frame.size.width, aSize.height);

推荐答案

在您的UIViewController上添加此代码

Add this code on your UIViewController

- (void)viewDidLayoutSubviews {
    [super viewDidLayoutSubviews];
    [myLabel sizeToFit];
    [self.view layoutIfNeeded];

    myLabel.preferredMaxLayoutWidth = myLabel.frame.size.width;
    [self.view layoutIfNeeded];
}
