SHXMLParser的使用报错-解析

-------------------------------------------------------------------------------------以上是错误信息-------------------------------------------------------------------------------------------

然后更近之后发现是字符串中有objectForKey    然后跟进程序找出报错点  然后自己修改程序源码

 原本源码:

+ (NSArray *)convertDictionaryArray:(NSArray *)dictionaryArray toObjectArrayWithClassName:(NSString *)className classVariables:(NSArray *)classVariables
{
	NSMutableArray *objectArray = [NSMutableArray array];
	for (NSDictionary *dict in dictionaryArray) {
		id object = [[NSClassFromString (className)alloc] init];
		for (NSString *variable in classVariables) {
			[object setValue:[dict objectForKey:variable] forKey:variable];
		}
		[objectArray addObject:object];
	}
	return objectArray;
}

修改后的源码：

+ (NSArray *)convertDictionaryArray:(NSArray *)dictionaryArray toObjectArrayWithClassName:(NSString *)className classVariables:(NSArray *)classVariables
{
	NSMutableArray *objectArray = [NSMutableArray array];
    if (![dictionaryArray isKindOfClass:[NSArray class]]) {
        dictionaryArray=[NSArray arrayWithObjects:dictionaryArray, nil];
    }
	for (NSDictionary *dict in dictionaryArray) {
		id object = [[NSClassFromString (className)alloc] init];
		for (NSString *variable in classVariables) {
            if ([dict isKindOfClass:[NSDictionary class]]) {
                [object setValue:[dict objectForKey:variable] forKey:variable];
            }
            else{
                
            }
		}
		[objectArray addObject:object];
	}
	return objectArray;
}
