序言：
现在APP开发都少不了用户意见反馈这一界面，随着，大多新手涌入社会这一行业，为此写出这一文档。
正文：
意见反馈，无谓就是将用户的想法和建议，反馈到开发者这里，根据用户的反馈，做出相应的更改自己的软件。
第一步：
我们要添加3个协议。如下：
UITableViewDataSource,UITableViewDelegate,UITextFieldDelegate
第二步：
我们创建3对象。如下：
UITableView*_ZSJTableView;
UITextField*_ZSJField;
UIImageView*ZSJTOOLBackImageView;
第三步：
我们在创建2个可变的数组。或者一个，这里我们创建两个。如下;
@property(nonatomic,strong)NSMutableArray*_ZSJDataArray; @property(nonatomic ,strong)NSMutableArray*TextFieldArr;
第四步：
我们首先布局头部显示的排布。如下;
UIImageView*ZSJNavImageView=[[UIImageView alloc]initWithFrame:CGRectMake(0, 20, SCREENWight, 44)];
ZSJNavImageView.userInteractionEnabled=YES;
ZSJNavImageView.backgroundColor=[UIColor colorWithRed:190.0/255.0 green:190.0/255.0 blue:190.0/255.0 alpha:1];
UIButton*ReturnButton=[UIButton buttonWithType:UIButtonTypeCustom];
ReturnButton.frame=CGRectMake(15, 10, 10, 25);
[ReturnButton setImage:[UIImage imageNamed:@"Return.png"] forState:UIControlStateNormal];
[ReturnButton addTarget:self action:@selector(ReturnClick) forControlEvents:UIControlEventTouchUpInside];
[ZSJNavImageView addSubview:ReturnButton];
UILabel*FeedBackLabel=[[UILabel alloc]initWithFrame:CGRectMake(SCREENWight/2-50, 2, 100, 40)];
FeedBackLabel.[email protected]"意见反馈";
FeedBackLabel.textColor=[UIColor blackColor];
FeedBackLabel.textAlignment=NSTextAlignmentCenter;
[ZSJNavImageView addSubview:FeedBackLabel];
[self.view addSubview:ZSJNavImageView];
第五步：
我们要创建聊天的主要工具，UItableView。如下：
UIView*BackView=[[UIView alloc]initWithFrame:CGRectMake(0, 64, SCREENWight, SCREENHight-50-64)];
UIImageView*BackImageView=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, SCREENWight, BackView.frame.size.height)];
BackImageView.image=[UIImage imageNamed:@"zsj.png"];//添加聊天背景。
[BackView addSubview:BackImageView];
_ZSJTableView=[[UITableView alloc]initWithFrame:CGRectMake(0, 64, SCREENWight, BackView.frame.size.height) style:UITableViewStylePlain];
_ZSJTableView.backgroundView=BackView;
_ZSJTableView.dataSource=self;
_ZSJTableView.delegate=self;
_ZSJTableView.separatorStyle=UITableViewCellSeparatorStyleNone;
[self.view addSubview:_ZSJTableView];
第六步：
我们实现UItableView的几个代理协议。如下：
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return self._ZSJDataArray.count;
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
NSString*ZSJStr=[self._ZSJDataArray[indexPath.row]firstObject];
CGFloat ZSJHight=[ZSJStr boundingRectWithSize:CGSizeMake(200, 1000) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSAttachmentAttributeName:[UIFont systemFontOfSize:16]} context:nil].size.height;
return ZSJHight+60;
}
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
ZSJMessageCell*cell=[tableView dequeueReusableCellWithIdentifier:@"ID"];
if (!cell) {
cell=[[ZSJMessageCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"ID"];
cell.selectionStyle=UITableViewCellSelectionStyleNone;
cell.backgroundColor=[UIColor clearColor];
}
NSArray*array=self._ZSJDataArray[indexPath.row];
[cell configModel:array];
return cell;
}
第七步：
我们要自定义Cell。如下：
1、创建几个对象。如下：
//做
UIImageView*LeftImageView;
UIImageView*LeftButtonImageView;
UILabel*LeftMessageLabel;
//有
UIImageView*RightImageView;
UIImageView*RightButtonImageView;
UILabel*RightMessageLabel;
2、我们要创建一个数据传入的方法。如下：
-(void)configModel:(NSArray*)array;
3、我们排布数据显示模式。
LeftImageView=[[UIImageView alloc]initWithFrame:CGRectMake(5, 5, 30, 30)];
LeftImageView.image=[UIImage imageNamed:@"zsjView.png"];
LeftImageView.layer.cornerRadius=15;
LeftImageView.layer.masksToBounds=YES;
[self.contentView addSubview:LeftImageView];
//右边头像
RightImageView=[[UIImageView alloc]initWithFrame:CGRectMake(ScreWight-35, 5, 30, 30)];
RightImageView.image=[UIImage imageNamed:@"2.jpg"];
RightImageView.layer.cornerRadius=15;
RightImageView.layer.masksToBounds=YES;
[self.contentView addSubview:RightImageView];
//左边气泡
LeftButtonImageView=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 100, 30)];
//处理拉伸图像
UIImage*leftImage=[UIImage imageNamed:@"fcl_chat_others"];
leftImage=[leftImage stretchableImageWithLeftCapWidth:20 topCapHeight:20];
LeftButtonImageView.image=leftImage;
[self.contentView addSubview:LeftButtonImageView];
//左边文字的label
LeftMessageLabel=[[UILabel alloc]initWithFrame:CGRectMake(5, 0, 100, 30)];
LeftMessageLabel.numberOfLines=0;
LeftMessageLabel.font=[UIFont systemFontOfSize:16];
[LeftButtonImageView addSubview:LeftMessageLabel];
//右边
RightButtonImageView=[[UIImageView alloc]initWithFrame:CGRectMake(200, 0, 100, 30)];
UIImage*image=[UIImage imageNamed:@"fcl_chat_me"];
image=[image stretchableImageWithLeftCapWidth:20 topCapHeight:20];
RightButtonImageView.image=image;
[self.contentView addSubview:RightButtonImageView];
RightMessageLabel=[[UILabel alloc]initWithFrame:CGRectMake(5, 0, 100, 30)];
RightMessageLabel.numberOfLines=0;
RightMessageLabel.font=[UIFont systemFontOfSize:16];
[RightButtonImageView addSubview:RightMessageLabel];
4、初入数据的实现。
CGSize size;
NSString*str=[array firstObject];
if ([[[UIDevice currentDevice]systemVersion]floatValue]>=7.0) {
//iOS7的方法
size=[str boundingRectWithSize:CGSizeMake(200, 1000) options:NSStringDrawingUsesLineFragmentOrigin attributes:@{NSFontAttributeName :[UIFont systemFontOfSize:16]} context:nil].size;
}else{
size=[str sizeWithFont:[UIFont systemFontOfSize:16] constrainedToSize:CGSizeMake(200, 1000)];
}
//取出是自己发送还是对方发送
if ([[array lastObject]isEqualToString:@"0"]) {
//对方发送
RightImageView.hidden=YES;
RightButtonImageView.hidden=YES;
LeftImageView.hidden=NO;
LeftButtonImageView.hidden=NO;
LeftButtonImageView.frame=CGRectMake(40, 5, size.width+10, size.height+15);
LeftMessageLabel.frame=CGRectMake(10, 6, size.width-5, size.height);
LeftMessageLabel.text=[array firstObject];
}else{
//自己发送
LeftImageView.hidden=YES;
LeftButtonImageView.hidden=YES;
RightImageView.hidden=NO;
RightButtonImageView.hidden=NO;
RightButtonImageView.frame=CGRectMake(ScreWight-40-size.width-10-10, 10, size.width+25, size.height+15);
RightMessageLabel.frame=CGRectMake(10, 6, size.width , size.height);
RightMessageLabel.text=[array firstObject];
}
第八步;
我们实现下面的数据输入实现框。如下：
ZSJTOOLBackImageView=[[UIImageView alloc]initWithFrame:CGRectMake(0, SCREENHight-50, SCREENWight, 50)];
ZSJTOOLBackImageView.backgroundColor=[UIColor colorWithRed:200.0/255.0 green:200.0/255.0 blue:200.0/255.0 alpha:1];
ZSJTOOLBackImageView.userInteractionEnabled=YES;
[self.view addSubview:ZSJTOOLBackImageView];
UIImageView*TextFieldBackView=[[UIImageView alloc]initWithFrame:CGRectMake(10, 8, SCREENWight-70-10, 36)];
TextFieldBackView.userInteractionEnabled=YES;
TextFieldBackView.layer.masksToBounds=YES;
TextFieldBackView.layer.cornerRadius=6;
TextFieldBackView.backgroundColor=[UIColor whiteColor];
[ZSJTOOLBackImageView addSubview:TextFieldBackView];
_ZSJField=[[UITextField alloc]initWithFrame:CGRectMake(5, 4, SCREENWight-70, 35)];
_ZSJField.delegate=self;
_ZSJField.returnKeyType=UIReturnKeySend;
[TextFieldBackView addSubview:_ZSJField];
UIButton*SeccseBtn=[UIButton buttonWithType:UIButtonTypeCustom];
SeccseBtn.frame=CGRectMake(SCREENWight-65, 6, 50, 46);
[SeccseBtn setBackgroundImage:[UIImage imageNamed:@"send.png"] forState:UIControlStateNormal];
[SeccseBtn setTitle:@"发送" forState:UIControlStateNormal];
[SeccseBtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[SeccseBtn addTarget:self action:@selector(SDClick:) forControlEvents:UIControlEventTouchUpInside];
[SeccseBtn sizeToFit];
[ZSJTOOLBackImageView addSubview:SeccseBtn];
第九步;
我们要实现发送代理和方法。如下：
if (_ZSJField.text.length>0) {
[self.TextFieldArr addObject:_ZSJField.text];
[self XieRuField];
NSLog(@"%@",self.TextFieldArr);
[self._ZSJDataArray addObject:@[_ZSJField.text,@"1"]];
[_ZSJTableView reloadData];
[_ZSJTableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:self._ZSJDataArray.count-1 inSection:0] atScrollPosition:UITableViewScrollPositionBottom animated:YES];
_ZSJField.text=nil;
[self performSelector:@selector(BackMessage) withObject:nil afterDelay:1];
}
第十步：
我们要实现键盘的收藏。如下;
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(showKeyBoard:) name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(hideKeyBoard:) name:UIKeyboardWillHideNotification object:nil];
