如何在xcode中增加导航栏的高度？ [英] how to increase the height of navigation bar in xcode?

问题描述

我正在开发一个应用程序，我需要在其中保留导航栏。
当我在酒吧写任何标题时，时间和标题有点非常接近。我想增加酒吧的高度，这样可以获得一些喘息的空间。

I'm working on a app,in which I need to keep a navigation bar. when I write any title on the bar,the time and the title kinda get very close to each other.I wanted to increase the height of the bar,so it can get some breathing room.

以编程方式

在 viewWillAppear 中添加此项或 viewDidAppear 方法

Objective-C

[self.navigationController.navigationBar setFrame:CGRectMake(0, 0, self.view.frame.size.width,80.0)];

Swift

self.navigationController.navigationBar.frame = CGRectMake(0, 0, self.view.frame.size.width, 80.0)

Swift-3

self.navigationController!.navigationBar.frame = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: 80.0)

iOS 11

目标C

for (UIView *subview in self.navigationController.navigationBar.subviews) {
    if ([NSStringFromClass([subview class]) containsString:@"BarBackground"]) {
        CGRect subViewFrame = subview.frame;
        // subViewFrame.origin.y = -20;
        subViewFrame.size.height = 100;
        [subview setFrame: subViewFrame];
    }
}

swift

for subview in (self.navigationController?.navigationBar.subviews)! {
       if NSStringFromClass(subview.classForCoder).contains("BarBackground") {
            var subViewFrame: CGRect = subview.frame
            // subViewFrame.origin.y = -20;
            subViewFrame.size.height = 100
            subview.frame = subViewFrame

        }

    }
