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)];
