效果如下:

设置思路:
1.UINavigationBar代码
if (iOS11_Later) {
self.layoutMargins = UIEdgeInsetsZero;
for (UIView *subview in self.subviews) {
if ([NSStringFromClass(subview.class) containsString:@"ContentView"]) {
subview.layoutMargins = UIEdgeInsetsZero;//可修正iOS11之后的偏移
}
}
}
2.UINavigationItem代码
if ([item.customView isKindOfClass:[UIButton class]]){
UIButton *leftBtn = item.customView;
if (!item.fixedState) {
UIEdgeInsets earlyEdge = leftBtn.contentEdgeInsets;
earlyEdge.left += 15;
leftBtn.width += 15;
leftBtn.contentEdgeInsets = earlyEdge;
item.fixedState = @"setted";
}
}else{
UIBarButtonItem *fixBtn = [self fixedSpaceWithWidth:15];
[self JR_setLeftBarButtonItems:@[fixBtn,item]];
return;
}
