越来越sigarbt错误
PlistReader *pList = [[PlistReader alloc] init];
[pList initWithFileName:@"CountryDetails"];
CountryClass *objcountry =(CountryClass*) [pList getCountryInfoById:countryId];
CCSprite *flag = [CCSprite spriteWithFile:objcountry.ImageUrl];
flag.position = ccp(200, 265);
flag.scale = .255;
NSString *tempdata = objcountry.ShortDetail;//error line sigabrt
TextViewTopFlagData = [[UITextView alloc]init];
TextViewTopFlagData.text = [NSString stringWithFormat:@"this is pakistan"];//countryInfo.ShortDetail;
TextViewTopFlagData.frame = CGRectMake(260,17, 105, 75);
TextViewTopFlagData.backgroundColor = [UIColor clearColor];
[TextViewTopFlagData setEditable:NO];
你好我过得好行错误SIGABRT我提到它objcountry.ShortDetail也在这里NSString的类型,以便它为什么得到错误SIGABRT任何一个可以帮助越来越sigarbt错误
时我把NSString * tempdata = objcountry.ShortDetail;//错误线sigabrt之前的精灵线它没有错误,但当我放回精灵线后,它又得到了那个错误,所以任何人可以解释我,

这是countryClass结构,我也试图[countryInfo保留],但没有happend
objcountry
不是CountryClass
的实际实例,它是某种其他类型的对象(不管[pList getCountryInfoById:country]
返回)。如果代码不明显,请尝试使用NSLog(@"objcountry is a %@", [objcountry class]);
将其打印出来。
表达式objcountry.ShortDetail
是属性存取方法[objcountry ShortDetail]
的语法糖。当运行时试图将消息ShortDetail
发送到obejct,但对象不响应该消息时,将引发可怕的NSInvalidArgumentException
消息“无法识别的选择器发送到类”(这应该打印到调试控制台)。如果没有人捕获到该异常(通常情况下),则运行时通过调用abort(3)
方法进行响应,该方法使用SIGABRT
信号终止应用程序。
谢谢你的回复,但是当我把NSString * tempdata = objcountry.ShortDetail; //错误线sigabrt 之前的精灵线它没有错误,但是当我放回精灵线后它再次得到该错误,所以你能解释我 – 2011-12-19 06:28:50
你能告诉我们 - (CountryClass *)getCountryInfoById:和CountryClass.h吗? – 2011-12-19 06:11:21
也许加载的精灵导致您的autorelease池清空。尝试[objcountry retain];在NCString * tempdata之后的CCSprite * flag ...和[objcountry release]之前...如果这不起作用,您将需要在崩溃时显示更多代码和调试器输出 – 2011-12-19 06:44:30
我提供类现在检查它 – 2011-12-19 08:12:08
