如何显示UILabel中方法的结果 [英] how to display results from a method in UILabel

问题描述

使用以下代码，我正在连接到Google API，当我单击按钮时，调用以下方法的结果将显示在标签字段上.

Using the following code I am connecting to Google API and when I click the button the result of the following method been called will display on label field.

我的问题是如何在标签字段中显示更多方法?

My question is how to display more methods in a label field?

例如，我想在标签"字段中显示一些4种方法或多个结果.

For example I want to display some 4 methods or multiple results in Label field.

在下面的代码中，我仅调用一种方法并仅显示一个结果.

In the code below I'm just calling one method and displaying only one result.

我想显示更多结果或多个结果，类似于Google搜索.

I want to display more results or multiple results something similar to Google search.

// .h file

{
IBOutlet UILabel* label;
NSMutableData *dataWebService; 
}

@property (retain, nonatomic) NSMutableData *dataWebService;
-(IBAction)loadData;



// .m file

- (void)loadData

{

dataWebService = [[NSMutableData data] retain];

NSURLRequest *request = [[NSURLRequest requestWithURL:[NSURL URLWithString:@"https://www.googleapis.com/customsearch/v1?key=AIzaSyDzl0Ozijg2C47iYfKgBWWkAbZE_wCJ-2U&cx=017576662512468239146:omuauf_lfve&q=lectures"]]retain];  

  [[NSURLConnection alloc]initWithRequest:request delegate:self];

}

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response 

{

[dataWebService setLength:0];

}



- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data

{

[dataWebService appendData:data];

}



- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error

{

NSLog(@"Error during connection: %@", [error description]);

}


- (void)connectionDidFinishLoading:(NSURLConnection *)connection 

{

[connection release];    
NSString *responseString = [[NSString alloc] initWithData:dataWebService encoding:NSUTF8StringEncoding];

self.dataWebService = nil;


// NSDictionary *dictionary = [responseString JSONValue];

NSDictionary *dictionaryReturn = (NSDictionary*) [[responseString JSONValue] objectForKey:@"context"]; 
[responseString release];    


NSString *name = (NSString*) [dictionaryReturn objectForKey:@"title"];

label.text = [NSString stringWithFormat:@"lectures title: %@",name];    


}

欢迎使用示例代码.

推荐答案

好吧，让我说清楚...您想在同一个UILabel中显示多个结果吗?如果是这样，则如果一次要显示多个结果，则最好使用UITextView或更佳的UITableView.UI标签是非常有限的.

Well, let me get this straight... You want to display multiple results within the same UILabel? If so, if you want to display more than one result at a time, you're best using a UITextView or better yet a UITableView. UI Labels are pretty limiting.

如果您想向UILabel添加更多行，则可以使用

If you want to add more lines to a UILabel though, you can use

textLabel.lineBreakMode = UILineBreakModeWordWrap;
textLabel.numberOfLines = 0;

我希望我能在正确的轨道上理解您的问题.

I hope I was on the right track understanding your question.
