iOS11以下偏移方案:
UIButton *settingBtn = [UIButton alloc]init];
UIBarButtonItem *rightBar = [[UIBarButtonItem alloc]initWithCustomView:settingBtn];
UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
negativeSpacer.width = -10;
self.navigationItem.rightBarButtonItems = [NSArray arrayWithObjects:negativeSpacer,rightBar,nil];
iOS11发现以上方法不能用了,iOS11请看分割线下面
感谢 stackoverflow上的朋友提供的解决办法
首先自定义navigationBar,
#import "LZJNavigationBar.h"
@implementationLZJNavigationBar
static CGFloat const mySpacer = -5;//item边距设置
- (void)layoutSubviews {
[super layoutSubviews];
if(@available(iOS11, *)) {
self.layoutMargins = UIEdgeInsetsZero;
for(UIView*subviewinself.subviews) {
if ([NSStringFromClass([subview class]) containsString:@"ContentView"]) {
UIEdgeInsets myEdge = subview.layoutMargins;
subview.layoutMargins=UIEdgeInsetsMake(0, myEdge.left+mySpacer,0, myEdge.right+mySpacer);
}
}
}
}
@end
使用方法
CustomViewController *VC =[[CustomViewController alloc]init];
UINavigationViewController *nav = [[UINavigationViewController alloc] initWithNavigationBarClass:[LZJNavigationBar class] toolbarClass:nil];
[nav setViewControllers:@[VC] animated:NO];
然后再使用最iOS11以下的偏移方法,生效!
完美解决
