2017-05-11 10:08:16.589 tentativaJSON[4082:90b] pontos
所以我想捕获pontos的详细信息，但它只显示它，我需要使用 Id 的值和其中的其他信息来执行与之相关的按钮，使用这个//http://api.iospond.com/api/index.php/GetData 我没有任何问题，但是如果我使用它//http://blessing.com.br/aplicativos/pontos.php 我会收到此错误 线程 1：信号 SIGABRT， 有人可以帮忙吗？
你应该使用 GET ：-
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:[NSString
stringWithFormat:@"http://api.iospond.com/api/index.php/GetData"]]];
[request setHTTPMethod:@"GET"];
[request setTimeoutInterval:60];
[NSURLConnection sendAsynchronousRequest:request queue:
[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *response,
NSData *data, NSError *error) {NSString *str = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
if ([(NSHTTPURLResponse *)response
statusCode] == 200) {
NSArray *dict = (NSArray *)str;
NSLog(@"Parse here:: %@",dict);
}else {
NSLog(@"elseelse
%@",error.localizedDescription);
}
}];
- 然后检查您获取数组或字典以逐步解析。
NSDictionary *dic in json
只会给你钥匙。要获取其值，请使用
json[dic]
