如何增加Xcode中导航栏的高度? [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，我需要在其中保留一个导航栏.当我在栏上写任何标题时，时间和标题会变得非常接近.我想增加吧台的高度，这样它就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.

目标 C

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

迅捷

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];
    }
}

迅速

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

        }

    }
