按钮调整布局

- (void)layoutSubviews {
    [super layoutSubviews];
    self.imageView.frame = CGRectMake(20, 20, [UIScreen mainScreen].bounds.size.width / 4 - 45, [UIScreen mainScreen].bounds.size.width / 4 - 45);
    self.titleLabel.frame = CGRectMake(0, [UIScreen mainScreen].bounds.size.width / 4 - 25, [UIScreen mainScreen].bounds.size.width / 4, 25);
}

搜索框键盘下落

_collectionView.keyboardDismissMode =  UIScrollViewKeyboardDismissModeOnDrag;

设置部分字段不同字体颜色

NSRange range = [cell.titleLabel.text rangeOfString:_searchString options:NSCaseInsensitiveSearch];
        [self setTextColor:cell.titleLabel FontNumber:cell.titleLabel.font AndRange:range AndColor:[UIColor colorWithRed:0/255.0 green:188/255.0 blue:212/255.0 alpha:1]];

-(void)setTextColor:(UILabel *)label FontNumber:(id)font AndRange:(NSRange)range AndColor:(UIColor *)vaColor
{
    NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:label.text];
    //设置字号
    [str addAttribute:NSFontAttributeName value:font range:range];
    //设置文字颜色
    [str addAttribute:NSForegroundColorAttributeName value:vaColor range:range];
    
    label.attributedText = str;
}

tableView去除多余行

_tableView.tableFooterView = [[UIView alloc]init];

导航跳转到某一个控制器

for (UIViewController *temp in self.navigationController.viewControllers) {
                    if ([temp isKindOfClass:[SuyanSDKMessageController class]]) {
                        [self.navigationController popToViewController:temp animated:YES];
                    }
                }

导航条自定义跳转

NSMutableArray *array = [NSMutableArray array];
    [self.navigationController.viewControllers enumerateObjectsUsingBlock:^(__kindof UIViewController * _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        if ([obj isKindOfClass:[XBHomeViewController class]]) {
            [array addObject:obj];
        }
    }];
    XBMyOrderViewController *detailVC = [XBMyOrderViewController controller];
    [array addObject:detailVC];
    [self.navigationController setViewControllers:array animated:YES];

自定义cell侧滑

-(void)layoutSubviews
{
    [super layoutSubviews];
    for (UIView *subView in self.subviews){
        if([subView isKindOfClass:NSClassFromString(@"UITableViewCellDeleteConfirmationView")]){
            UIButton* deleteBtn = [UIButton buttonWithType:UIButtonTypeCustom];
            deleteBtn.frame = subView.bounds;
            [deleteBtn setTitle:@"取消关注" forState:UIControlStateNormal];
            [deleteBtn.titleLabel setFont:[UIFont systemFontOfSize:14]];
            [deleteBtn setTitleColor:[UIColor colorWithRed:253/255.0 green:206/255.0 blue:7/255.0 alpha:1] forState:UIControlStateNormal];
            deleteBtn.backgroundColor = [UIColor colorWithRed:245/255.0 green:245/255.0 blue:245/255.0 alpha:1];
            [subView addSubview:deleteBtn];
            break;
        }
    }
}
