在我的 iPad 应用程序中删除运行时内存泄漏时,我在以下方法中的 NSObject+JSONSerializableSupport 类中遇到了这个奇怪的内存泄漏
+ (id) deserializeJSON:(id)jsonObject {
id result = nil;
if ([jsonObject isKindOfClass:[NSArray class]]) {
//JSON array
result = [NSMutableArray array];
for (id childObject in jsonObject) {
[result addObject:[self deserializeJSON:childObject]];
}
}
else if ([jsonObject isKindOfClass:[NSDictionary class]]) {
//JSON object
//this assumes we are dealing with JSON in the form rails provides:
// {className : { property1 : value, property2 : {class2Name : {property 3 : value }}}}
NSString *objectName = [[(NSDictionary *)jsonObject allKeys] objectAtIndex:0];
Class objectClass = NSClassFromString([objectName toClassName]);
if (objectClass != nil) {
//classname matches, instantiate a new instance of the class and set it as the current parent object
result = [[[objectClass alloc] init] autorelease];
}
NSDictionary *properties = (NSDictionary *)[[(NSDictionary *)jsonObject allValues] objectAtIndex:0];
NSDictionary *objectPropertyNames = [objectClass propertyNamesAndTypes];
for (NSString *property in [properties allKeys]) {
NSString *propertyCamalized = [[self convertProperty:property andClassName:objectName] camelize];
if ([[objectPropertyNames allKeys]containsObject:propertyCamalized]) {
Class propertyClass = [self propertyClass:[objectPropertyNames objectForKey:propertyCamalized]];
[result setValue:[self deserializeJSON:[propertyClass deserialize:[properties objectForKey:property]]] forKey:propertyCamalized];
}
}
}
else {
//JSON value
result = jsonObject;
}
return result;
}
我在这条线上遇到了内存泄漏
[result setValue:[self deserializeJSON:[propertyClass deserialize:[properties objectForKey:property]]] forKey:propertyCamalized];
请提出解决方案或告诉我哪里出错了。
