ios 修改导航条返回按钮

ios 修改导航条返回按钮

方式一：使用系统的；可以更改系统的文字；以及通过设置导航条的颜色来达到预期的效果

UIBarButtonItem *backBtns = [[UIBarButtonItem alloc]initWithTitle:@"返回" style:UIBarButtonItemStylePlain target:nil action:nil];
self.navigationItem.backBarButtonItem = backBtns;
[self.navigationController.navigationBar setTintColor:[UIColor whiteColor]];

方式二：

通过UIBarButtonItem的创建一个custom, 通过创建一个uibutton来处理！

上述效果可以用一个UIButton 里面，同时设置一照片和文字来处理

//topNav
UIBarButtonItem *callItems = [[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:@"indexCALL"] style:UIBarButtonItemStylePlain target:self action:@selector(tapCallBtnAction)];
callItems.tintColor = [UIColor whiteColor];
self.navigationItem.rightBarButtonItem = callItems;

locBtn = [UIButton buttonWithType:UIButtonTypeCustom];
locBtn.frame = CGRectMake(0, 0, 50, 44);
[locBtn setTitle:@"返回" forState:UIControlStateNormal];
locBtn.titleLabel.textAlignment = NSTextAlignmentLeft;
[locBtn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[locBtn addTarget:self action:@selector(tapLocationBtnAction) forControlEvents:UIControlEventTouchUpInside];
locBtn.titleLabel.font = [UIFont boldSystemFontOfSize:17];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:locBtn];
[locBtn setImage:[UIImage imageNamed:@"indexArrow"] forState:UIControlStateNormal];
[locBtn setImageEdgeInsets:UIEdgeInsetsMake(0, 30, 0, 0)];
[locBtn setTitleEdgeInsets:UIEdgeInsetsMake(0, -40, 0, 0)];
