关于自定义导航条UIBarButtonItem偏移的问题

在自定义导航条左按钮的时候发现按钮的位置向右偏移,下面给出了解决方法

主要还依赖于UIButton的属性设置

// 设置导航条的左按钮

UIButton *leftButton = [UIButton buttonWithType:UIButtonTypeCustom];

leftButton.frame = CGRectMake(0, 0, 32, 26);

leftButton.imageEdgeInsets = UIEdgeInsetsMake(0, -13, 0, 0);//　　设置按钮图片的偏移位置(向左偏移)

[leftButton setImage:[UIImage imageNamed:@"shouye-cehua"] forState:UIControlStateNormal];

[leftButton addTarget:self action:@selector(handleLeftButtonAction:) forControlEvents:UIControlEventTouchUpInside];

self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:leftButton];
