您可以使用以下代码行从NavigationBar中删除导航标题:
var env = require('minimist')(process.argv.slice(2)),
gulp = require('gulp'),
compass = require('gulp-compass'),
cssmin = require('gulp-cssmin'),
connect = require('gulp-connect')
gulp.task('js', function(){
return gulp.src('src/js/**/*.js')
.pipe(concat('main.js'))
.pipe(gulp.dest('build/js/'))
.pipe(connect.reload());
});
gulp.task('html', function(){
return gulp.src('src/templates/**/*.html')
.pipe(gulp.dest('build/'))
.pipe(connect.reload());
});
gulp.task('watch', function(){
gulp.watch('src/templates/**/*.html',['html']);
gulp.watch('src/sass/**/*.scss', ['compass']);
gulp.watch('src/js/**/*.js', ['js']);
gulp.watch('src/img/**/*.{jpg,png,gif}', ['imagemin']);
});
gulp.task('connect', function() {
connect.server({
root: ['build/'],
livereload: true,
middleware: function(){
return [
modRewrite([
'^/$ /index.html',
'^([^\\.]+)$ $1.html'
])
];
}
});
});
gulp.task('default', ['js','html','watch','connect']);
希望它会对你有所帮助。

您也可以使用以下代码进行更改:
[self.navigationItem.backBarButtonItem setTitle:@"Title here"];
如果你想设置后面的按钮标题是空白的...那么只需要在这里放置标题只放置空格
<强> 2 强>
或者这样做:
UIBarButtonItem *btn = [[UIBarButtonItem alloc]init];
btn.title=@"";
self.navigationItem.leftBarButtonItem=btn;
第3 强>
从界面构建器中选择导航项,然后将后退按钮字符串更改为您希望后退按钮显示为的内容。如果你想把它留空,那就放一个空格。
标题颜色
<强> 1 强>
NSDictionary *titlecolor =@{
NSForegroundColorAttributeName : [UIColor whiteColor]
};
分配字典
[[self navigationItem] setTitle:@"Your Title"];
self.navigationController.navigationBar.titleTextAttributes = titlecolor;
<强> 2 强>
假设您想要redColor
self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor redColor] forKey:NSForegroundColorAttributeName];
背景颜色
[[UINavigationBar appearance] setTintColor:[UIColor colorWithRed:107.0/256.0 green:145.0/256.0 blue:35.0/256.0 alpha:1.0]];

您需要为导航栏项目按钮标题设置空标题 你可以试试这个
[self.navigationItem.backBarButtonItem setTitle:@" "];
OR
您还可以为导航栏项目按钮指定新按钮
UIBarButtonItem *myButton =
[[UIBarButtonItem alloc] initWithTitle:@" "
style:UIBarButtonItemStyleBordered
target:nil
action:nil];
[[self navigationItem] setBackBarButtonItem:myButton];
