ios怎么设置navigationbar的titleview的宽度

Posted 2023-03-15

参考技术A 这个要用自定义的view才能设置：方法如下//设置标题//self.title=@"title1";//修改title会改变navigationItem。title，但反之不会，一般设置title用此方法就好了//self.navigationController.title=@"title2";////自定义标题//UIView*view=[[UIViewalloc]initWithFrame:CGRectMake(0,0,100,44)];//view.backgroundColor=[UIColorredColor];UILabel*title=[[UILabelalloc]initWithFrame:CGRectMake(0,0,100,44)];title.text=@"title3";title.textAlignment=NSTextAlignmentCenter;title.textColor=[UIColorredColor];self.navigationItem.titleView=title;
