1.计算Lable文字分行的行高
-(CGFloat)heightWithLable:(NSString*)txtStr andFont:(CGFloat)font andWidth:(CGFloat)width
{ return [txtStr boundingRectWithSize:CGSizeMake(width, 10000) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:font]} context:nil].size.height;
}
2.TableVIewCell以及动态高度总结

3.自定义tableView的XIB
cell=[[[NSBundle mainBundle]loadNibNamed:@"TableCell" owner:nil options:nil]lastObject];
4.超强alertview alertcontroller的封装

6.pch文件配置：
$(SRCROOT)/Public.pch
7.创建一个btn为新的barbutton
UIBarButtonItem *left=[[UIBarButtonItem alloc]initWithCustomView:backBtn];
//赋值给左边
[self.navigationItem setLeftBarButtonItem:left];
8.代码块self弱引用
__weak typeof(self) weakSelf = self;
9.去除UITableView单元格默认的分割线,拖动没有线条显示
tableView.separatorStyle = NO;
10.去除UITableView单元格取消选择状态
cell.selectionStyle = UITableViewCellSelectionStyleNone;
11.调整section头滑动--tableView(头部粘合性)

12.xib拖拉-自定义的view
-(instancetype)init
{ if (self=[super init])
{ self=[[NSBundle mainBundle] loadNibNamed:@"FooterSectionV" owner:self options:nil][0];
}
return self;
}
注意：如果要规定view的大小，必须要写上self.frame=frame。不然view的尺寸会不固定
13.价格删除线
NSUInteger length = [good_TabCell.good_OriPriceLa.text length];
NSMutableAttributedString *attri = [[NSMutableAttributedString alloc] initWithString:good_TabCell.good_OriPriceLa.text];
[attri addAttribute:NSStrikethroughStyleAttributeName value:@(NSUnderlinePatternSolid | NSUnderlineStyleSingle) range:NSMakeRange(0, length)];
[attri addAttribute:NSStrikethroughColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0, length)];[good_TabCell.good_OriPriceLa setAttributedText:attri];
ceilf(height);//向上取整

15.单元格和列表逆序存放
hotCell.textLabel.text=self.oldArr[self.oldArr.count-1-indexPath.row];
16.把搜索记录数组记录存在缓存里面
NSUserDefaults *userDefaults=[NSUserDefaults standardUserDefaults];
NSMutableArray *searchArr=[userDefaults objectForKey:@"searchTxtArr"];
if (!searchArr||searchArr.count==0)
{
searchArr=[NSMutableArray new];
[userDefaults setObject:searchArr forKey:@"searchTxtArr"];
}
searchArr=searchArr.mutableCopy;
//把数据写入
[searchArr addObject:searchTerm];
self.oldArr=searchArr;
[userDefaults setObject:self.oldArr forKey:@"searchTxtArr"];
[userDefaults synchronize];
[self.searchTabV reloadData];
删除列表数据的方法
先删除缓存再删除列表,然后再更新

17.设置了按钮的selected的选择状态，必须要设置这个才有效
sender.selected=!sender.selected;

19.xib拖拉按钮时，自定义按钮，不然点击时会有蓝色一小点
选择和普通状态时候，按钮样式要设置成custom
20.直接选中第几个标签栏
self.navigationController.tabBarController.selectedIndex=2;

23.汉字转拼音代码
汉字转拼音：
//汉字转拼音
if ([city length])
{
NSMutableString *ms = [[NSMutableString alloc] initWithString:city];
if (CFStringTransform((__bridge CFMutableStringRef)ms, 0, kCFStringTransformMandarinLatin, NO))
{
NSLog(@"pinyin: %@", ms);
}
if (CFStringTransform((__bridge CFMutableStringRef)ms, 0, kCFStringTransformStripDiacritics, NO))
{
NSLog(@"pinyin: %@", ms);
NSArray *arr=[ms componentsSeparatedByString:@" "];
ms=[NSMutableString new];
for (NSString *str in arr)
{
[ms appendString:str];
}
city=ms;
}
}
24.修改Tableview的分割线长度和底部多余的分割线
//修改分割线长度
UIEdgeInsets edgeInset = _searchTabV.separatorInset;
_searchTabV.separatorInset = UIEdgeInsetsMake(edgeInset.top, 0, edgeInset.bottom, edgeInset.right);
//修改没有cell的分割线取消
_searchTabV.separatorStyle=UITableViewCellSeparatorStyleSingleLine;
_searchTabV.tableFooterView = [[UIView alloc] init];
25.自定义导航栏按钮会把自带的左滑手势给隐藏了，需要如下设置则可以使用
//开启iOS7的滑动返回效果
if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)])
{
self.navigationController.interactivePopGestureRecognizer.delegate = nil;
}
26.btn上的字左对齐和边距
btn文字左对齐
button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
button.titleEdgeInsets = UIEdgeInsetsMake(0, 10, 0, 0);
