2014-07-20 09:29:22.625 EE[4636:60b] Request Failed with Error: Error Domain=NSURLErrorDomain Code=-1000 "bad URL" UserInfo=0x15ed01a0 {NSUnderlyingError=0x15e99620 "bad URL", NSLocalizedDescription=bad URL}

从此：

[formatter setDateFormat:@"MM-dd-yyyy HH:mm:ss"];
        NSDate *alertTime = [formatter dateFromString:str];
        //NSDate *alertTime = [[NSDate date] dateByAddingTimeInterval:60];

要

[formatter setDateFormat:@"dd-MM-yyyy h:mm:ss a"];
        NSDate *alertTime = [formatter dateFromString:str];
        //NSDate *alertTime = [[NSDate date] dateByAddingTimeInterval:60];

从24小时变为上午/下午后，我收到了上述错误消息，请问在这种情况下我做错了什么？

根据@skrew建议，这是我在代码中使用的内容：

    static NSString AFPercentEscapedQueryStringPairMemberFromStringWithEncoding(NSString   *string, NSStringEncoding encoding) {
// Escape characters that are legal in URIs, but have unintentional semantic significance when used in a query string parameter
static NSString * const kAFLegalCharactersToBeEscaped = @":/.?&=;+!@$()~";

return [(NSString *)CFURLCreateStringByAddingPercentEscapes(kCFAllocatorDefault,   (CFStringRef)string, NULL, (CFStringRef)kAFLegalCharactersToBeEscaped, CFStringConvertNSStringEncodingToEncoding(encoding)) autorelease];
}

您必须对URL进行编码，因为您现在有一个空格（上午10:00）

添加NSString + URLEncoding.h：

- (NSString *)urlEncode;

添加NSString + URLEncoding.m：

- (NSString *)urlEncode
{
    return (__bridge_transfer NSString *)CFURLCreateStringByAddingPercentEscapes(NULL,
                                                                            (__bridge CFStringRef)self,
                                                                            NULL,
                                                                            (CFStringRef)@"!*'();:@&=+$,/?%#[] ",
                                                                            kCFStringEncodingUTF8);
}

在您的代码中，构建网址时，请添加：

NSString *url = [url urlEncode];

如果你不想要上面的所有代码，可以使用quickfix（但不推荐）来替换url中的空格

url = [url stringByReplacingOccurrencesOfString: @" " withString: @"%20"];

BAD URL错误，因为我从24小时变为上午/下午
