我正在与Rubymotion进行SendBird聊天集成。由于我对Objective-C / Swift结构的了解有限,我无法从SDK获取消息传递通道列表,因此我遇到了一些问题。
我很感激帮助将以下代码翻译成RubyMotion代码:
目标-C:
- (void) queryMessagingChannels
{
messagingChannelListQuery = [SendBird queryMessagingChannelList];
[messagingChannelListQuery setLimit:15];
[messagingChannelListQuery nextWithResultBlock:^(NSMutableArray *queryResult) {
...
for (int i = 0; i < [queryResult count]; i++) {
SendBirdMessagingChannel *mc = (SendBirdMessagingChannel *)[queryResult objectAtIndex:i];
...
}
...
} endBlock:^(NSError *error) {
}];
}
夫特:
func queryMessagingChannels() {
messagingChannelListQuery = SendBird.queryMessagingChannelList()
messagingChannelListQuery?.setLimit(15)
messagingChannelListQuery?.nextWithResultBlock({ (queryResult) -> Void in
....
for model in queryResult {
let mc: SendBirdMessagingChannel = model as! SendBirdMessagingChannel
....
}
....
}, endBlock: { (code) -> Void in
})
}
到目前为止,我有这个,但它失败了,错误。
Rubymotion:
mp "Iterating over MessagingChannelList"
@messagingChannelListQuery = SendBird.queryMessagingChannelList()
@messagingChannelListQuery.setLimit(5)
@messagingChannelListQuery.nextWithResultBlock.each do |queryResult|
@messaging_channels << queryResult
end
# reload tableview data here
错误:
chat_messaging_screen.rb:49:in `load_async': undefined method `nextWithResultBlock' for #<SendBirdMessagingChannelListQuery:0x117c672e0> (NoMethodError)
在这种情况下,我真的不知道如何正确设置块。
答案 0 :(得分:0)
确定。所以nextWithResultBlock实际上也需要传递endBlock,所以这最终解决了它:
@messagingChannelListQuery.nextWithResultBlock(
-> (queryresult) {
#do something here with queryresult.each
},
endBlock: -> (code) {
}
)
NoMethodError让我失望。
