我这个项目整体是基于swift编写的，但是在集成TIM的时候本是就遇到了很多问题，这里分享一下swift中TIM SDK的自定义消息发送。在搜索腾讯官方文档和google后，发现没有直接能拿来就用的，所以就想给自己总结一下，特此做个笔记。
首先项目是需要web端发送一个自定义消息，iOS端需要显示这个自定义消息，自定义消息中data数据需要自己看一下腾讯官方文档，和服务端协商定制。下面我就简单明了的说明！
一、需要一个自定义的Cell，找到ChatTableViewCell
ChatTableViewCell 中添加自定义cell
在ChatTableViewCell.h中添加一下代码
//==============================================================
@interfaceChatCustomTableViewCell :ChatBaseTableViewCell
{
@protected
UILabel*_descLabel;//商品描述
UILabel*_seperateLabel;//分割线
UILabel*_addressLabel;//地址信息
}
//连接地址
#define KTIMCustomDataurl @"dataurl"
//年纪
#define KTIMCustomVisitage @"visitage"
//性别
#define KTIMCustomVisitsex @"visitsex"
//姓名
#define KTIMCustomVisitname @"visitname"
在ChatTableViewCell.m中添加一下代码
//==============================================================
@implementationChatCustomTableViewCell
- (UIView*)addElemContent
{
// 底层View
_elemContentRef=[[UIView alloc]init];
[_elemContentRef setBackgroundColor:UIColor.whiteColor];
_elemContentRef.layer.cornerRadius = 8.0;
// 标题描述
_titleLabel = [[UILabel alloc] init];
_titleLabel.textAlignment = NSTextAlignmentLeft;
_titleLabel.numberOfLines = 0;
_titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
_titleLabel.userInteractionEnabled = YES;
_titleLabel.font = [UIFont systemFontOfSize:14.0];
_titleLabel.textColor = UIColor.grayColor;
[_elemContentRef addSubview:_titleLabel];
// 分割线
_seperateLabel=[[UILabel alloc]init];
_seperateLabel.backgroundColor=UIColor.brownColor;
_seperateLabel.userInteractionEnabled = YES;
[_elemContentRef addSubview:_seperateLabel];
// 咨询的描述问题
_descLabel=[[UILabel alloc]init];
_descLabel.font=[UIFont systemFontOfSize:12.0];
_descLabel.textColor=UIColor.grayColor;
_descLabel.numberOfLines=2;
_descLabel.textAlignment= NSTextAlignmentLeft ;
_descLabel.userInteractionEnabled = YES;
[_elemContentRef addSubview:_descLabel];
//添加约束
[self keepDistanse];
// 配置数据
[self configContent];
// 添加手动触发事件
[selfTapGest];
return _elemContentRef;
}
//设置约束
-(void)keepDistanse
{
//设置约束
[_titleLabel mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.mas_equalTo(self->_elemContentRef.top).offset(6);
make.left.mas_equalTo(self->_elemContentRef.left).offset(15);
make.right.mas_equalTo(self->_elemContentRef.right).offset(-15);
make.height.mas_equalTo(@16);
}];
[_seperateLabel mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.mas_equalTo(self->_elemContentRef.top).offset(6+6+16+8);
make.left.mas_equalTo(self->_elemContentRef.left).offset(+15);
make.height.mas_equalTo(@0.5);
make.right.mas_equalTo(self->_elemContentRef.right).offset(-15);
}];
[_descLabel mas_makeConstraints:^(MASConstraintMaker *make) {
make.top.mas_equalTo(self->_elemContentRef.top).offset(6+6+16+8+8.5+14+14);
make.left.mas_equalTo(self->_elemContentRef.left).offset(+15);
make.height.lessThanOrEqualTo(@32);
make.right.mas_equalTo(self->_elemContentRef.right).offset(-12);
}];
}
- (void)configContent {
[super configContent];
TIMMessage* message=_msg.msg;
TIMElem* item=[messagegetElem:0];
if([item isKindOfClass:[TIMCustomElem class]]){
TIMCustomElem* elem=(TIMCustomElem*)item;
NSData* data=elem.data;
NSDictionary* dict= [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:nil];
//给各个控件赋值
_titleLabel.text = [NSString stringWithFormat:@"患者信息: %@ %@ %@",dict[KTIMCustomVisitname],dict[KTIMCustomVisitsex],dict[KTIMCustomVisitage]];
_descLabel.text=[NSString stringWithFormat:@"患者的问题: %@",dict[KTIMCustomVisitage]];
}
}
- (void)TapGest {
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(onTapCustomMsg:)];
tap.numberOfTapsRequired = 1;
tap.numberOfTouchesRequired = 1;
[_elemContentRef addGestureRecognizer:tap];
}
- (void)onTapCustomMsg:(UITapGestureRecognizer*)tap
{
if (tap.state == UIGestureRecognizerStateEnded)
{
UIStoryboard* sb =
[UIStoryboard storyboardWithName:@"ComWebview" bundle:nil];
ComWebviewController * lvc =
[sbinstantiateViewControllerWithIdentifier:@"ComWebviewController"];
UINavigationController *nc = [self currentNC ];
[ncpushViewController:lvc animated:YES];
}
}
// 获取当前Controller
-(UIViewController*)getSuperController{
UIViewController *vc = [[UIViewController alloc]init];
for(UIView* next = [selfsuperview]; next; next = next.superview){
UIResponder* nextResponder = [nextnextResponder];
if ([nextResponder isKindOfClass:[UIViewController class]]){
vc = (UIViewController*)nextResponder;
break;
}
}
returnvc;
}
// 获取当前Navigation
- (UINavigationController *)currentNC
{
if (![[UIApplication sharedApplication].windows.lastObject isKindOfClass:[UIWindow class]]) {
NSAssert(0,@"未获取到导航控制器");
returnnil;
}
UIViewController *rootViewController = [UIApplication sharedApplication].keyWindow.rootViewController;
return[selfgetCurrentNCFrom:rootViewController];
}
- (UINavigationController *)getCurrentNCFrom:(UIViewController *)vc
{
if ([vc isKindOfClass:[UITabBarController class]]) {
UINavigationController *nc = ((UITabBarController *)vc).selectedViewController;
return [self getCurrentNCFrom:nc];
}
else if ([vc isKindOfClass:[UINavigationController class]]) {
if (((UINavigationController *)vc).presentedViewController) {
return [self getCurrentNCFrom:((UINavigationController *)vc).presentedViewController];
}
return [self getCurrentNCFrom:((UINavigationController *)vc).topViewController];
}
else if ([vc isKindOfClass:[UIViewController class]]) {
if (vc.presentedViewController) {
return [self getCurrentNCFrom:vc.presentedViewController];
}
else{
return vc.navigationController;
}
}
else{
NSAssert(0,@"未获取到导航控制器");
returnnil;
}
}
二、设置Cell的高度
首先腾讯的sdk本是就有问题，这个地方需要在TIMElem+ShowAPIs.m 自己定义实现方法，下面是路径
TIMElem+ShowAPIs 设置元素的高度
在TIMElem+ShowAPIs.m中TIMCustomElem添加一下代码
- (Class)showCellClassOf:(IMAMsg*)msg
{
if (msg.type == EIMAMSG_TimeTip)
{
return [ChatTimeTipTableViewCell class];
}
else if (msg.type == EIMAMSG_SaftyTip)
{
return [ChatSaftyTipTableViewCell class];
}
else if (msg.type == EIMAMSG_RevokedTip)
{
return [RevokedTipTableViewCell class];
}
else if (msg.type == EIMAMSG_Custom)
{
return [ChatCustomTableViewCell class];
}
else
{
return[supershowCellClassOf:msg];
}
}
//此方法需要自己单独实现，里面的高度可以设固定，也可以自己根据元素自己计算高度！
- (CGSize)sizeInWidth:(CGFloat)width atMsg:(IMAMsg*)packMsg
{
returnCGSizeMake(width,100);
}
