XML解析：
1、两层基础解析，对象里有对象
xml结构

头文件：
@class SHDetailDataModel; @interface SHRegisterDesignerModel : NSObject @property(nonatomic,strong)NSString * Result; @property(nonatomic,strong)NSString * Mesage; @property(nonatomic,strong)SHDetailDataModel * detailDataModel; +(id)praseSHRegisterDesignerModel:(NSString *)str; @end @interface SHDetailDataModel : NSObject @property(nonatomic,strong)NSString *soufunid; @property(nonatomic,strong)NSString *soufunName; @property(nonatomic,strong)NSString *RealName; @property(nonatomic,strong)NSString *CityName; @property(nonatomic,strong)NSString *Email; @property(nonatomic,strong)NSString *logo; @property(nonatomic,strong)NSString *soufunmobile; @property(nonatomic,strong)NSString *CompanyName; @property(nonatomic,strong)NSString *Type; @end
实现：
@implementation SHRegisterDesignerModel +(id)praseSHRegisterDesignerModel:(NSString *)str{ NSMutableArray * nodes = [[NSMutableArray alloc] init]; //Root节点下的第一层数据 [nodes addObject:@"//Root”]; //loginmsg节点下的数据 [nodes addObject:@"//Root//loginmsg”]; NSMutableArray * modes = [[NSMutableArray alloc] init]; //Root节点下的第一层数据的model类 [modes addObject:@"SHRegisterDesignerModel"]; //loginmsg节点下的数据model的类 [modes addObject:@"SHDetailDataModel"]; //nodes和modes的关系是一一对应的 id iret = [GDataParseXML utilitParseDataFromXML:str nodeArrary:nodes modeArrary:modes andOpption:NO]; return iret; } @end @implementation SHDetailDataModel @end
解析具体实现方法：
+ (id)utilitParseDataFromXML:(NSString *)xmlString nodeArrary:(NSMutableArray*) nodes modeArrary:(NSMutableArray*) modes andOpption:(BOOL) isArray { NSError *error; GDataXMLDocumentAnother *doc = [[GDataXMLDocumentAnother alloc] initWithXMLString:xmlString options:0 error:&error];

} }
2、两层数组解析，对象里有数组对象
基本同上，参考上面，将上层的model里面的属性改成执行类型model类的数组即可
对象里面有数组，xml的节点肯定会比上面多一层，数组的那一层，所以参考这个nodes，就会多一层，model还是各自对应的moel
+(id)parsePerformListModelWithXMLString:(NSString *)xmlString{ NSMutableArray *nodes=[[NSMutableArray alloc]init]; [nodes addObject:@"//root"]; //数据模型内层数据节点 [nodes addObject:@"//root//performance//performanceitem"]; NSMutableArray *modes=[[NSMutableArray alloc]init]; [modes addObject:@"PerformListModel"]; [modes addObject:@"PerformanceItem"]; id iret=[GDataParseXML utilitParseDataFromXML:xmlString nodeArrary:nodes modeArrary:modes andOpption:NO]; //id iret = [GDataXMLUtil utilitParseDataFromXML:xmlString nodeArrary:nodes modeArrary:modes opption:NO]; //GDataXMLUtil return iret; }
3、三层数据解析:对象里套对象数组，套对象数组
解析具体实现方法：
+ (id)utilitParseDataFromXML3:(NSString *)xmlString nodeArrary:(NSMutableArray*) nodes modeArrary:(NSMutableArray*) modes andOpption:(BOOL) isArray { NSError *error; GDataXMLDocumentAnother *doc = [[GDataXMLDocumentAnother alloc] initWithXMLString:xmlString options:0 error:&error]; if (doc == nil) { return nil; } if ([nodes count] != [modes count]) { [doc release]; return nil; } NSMutableArray * arrayForObjs = nil; if (isArray) { arrayForObjs = [[NSMutableArray alloc] init]; } NSMutableArray *array = nil; NSMutableArray * propertyBase = [[NSMutableArray alloc] init]; NSMutableDictionary *propertyDicBase =[[NSMutableDictionary alloc] init]; id baseObj = [[NSClassFromString([modes objectAtIndex:0]) alloc] init]; [GDataParseXML propertyMutableArray:propertyBase obj:baseObj]; [GDataParseXML propertyDictionary:propertyDicBase obj:baseObj]; int index =0; for (int i = 0;i< [nodes count]-1 ;i++) { id obj = nil; NSMutableArray * propertyNames =nil; NSMutableDictionary *propertyDic =nil; if (i!= 0) { for (NSString* keystr in propertyBase) { if((index == [propertyBase indexOfObject:keystr]) && [[propertyDicBase objectForKey:keystr] isEqualToString:@"NSMutableArray"]){ array = [[NSMutableArray alloc] init]; } } if (array == nil) { propertyNames = [[NSMutableArray alloc] init]; propertyDic =[[NSMutableDictionary alloc] init]; obj = [[NSClassFromString([modes objectAtIndex:i]) alloc] init]; [GDataParseXML propertyMutableArray:propertyNames obj:obj]; [GDataParseXML propertyDictionary:propertyDic obj:obj]; } } NSArray *base = [doc nodesForXPath:[nodes objectAtIndex:i] error:nil]; if (![base count]) { [array release]; [obj release]; obj = nil; array = nil; } for (GDataXMLNodeAnother *thisObeject in base){ id iret = nil; if(i == 1){ NSMutableArray * nodes2 = [[NSMutableArray alloc] init]; [nodes2 addObject:[nodes objectAtIndex:2]]; NSMutableArray * modes2 = [[NSMutableArray alloc] init]; [modes2 addObject:[modes objectAtIndex:2]]; iret = [GDataParseXML utilitParseDataFromXML:thisObeject.XMLString nodeArrary:nodes2 modeArrary:modes2 andOpption:YES]; [nodes2 release]; [modes2 release]; } if (obj == nil && i!=0 && !isArray) { propertyNames = [[NSMutableArray alloc] init]; propertyDic =[[NSMutableDictionary alloc] init]; obj = [[NSClassFromString([modes objectAtIndex:i]) alloc] init]; [GDataParseXML propertyMutableArray:propertyNames obj:obj]; [GDataParseXML propertyDictionary:propertyDic obj:obj]; } else if(baseObj == nil && isArray){ baseObj = [[NSClassFromString([modes objectAtIndex:0]) alloc] init]; [GDataParseXML propertyMutableArray:propertyBase obj:baseObj]; [GDataParseXML propertyDictionary:propertyDicBase obj:baseObj]; } for (GDataXMLNodeAnother * node in [(GDataXMLElementAnother *)thisObeject attributes]){ if (i==0) { for (NSString* keystr in propertyBase) { if ([[node localName] isEqualToString:keystr] && [[propertyDicBase objectForKey:keystr] isEqualToString:@"NSString"]) { [baseObj setValue:[node stringValue] forKey:keystr]; index++; } } } else { for (NSString* keystr in propertyNames) { if ([[node localName] isEqualToString:keystr] && [[propertyDic objectForKey:keystr] isEqualToString:@"NSString"]) { [obj setValue:[node stringValue] forKey:keystr]; } } } } for (GDataXMLElementAnother *node in [thisObeject children]){ NSString* temp = [[NSString alloc] initWithString:[node stringValue]]; if (i==0) { for (NSString* keystr in propertyBase) { if ([[node localName] isEqualToString:keystr] && [[propertyDicBase objectForKey:keystr] isEqualToString:@"NSString"]) { [baseObj setValue:temp forKey:keystr]; index++; } } } else { for (NSString* keystr in propertyNames) { if ([[node localName] isEqualToString:keystr] && [[propertyDic objectForKey:keystr] isEqualToString:@"NSString"]) { [obj setValue:temp forKey:keystr]; } if ([[propertyDic objectForKey:keystr] isEqualToString:@"NSMutableArray"]) { [obj setValue:iret forKey:keystr]; } } } [temp release]; } if (array != nil) { [array addObject:obj]; [obj release]; obj = nil; [propertyNames release]; [propertyDic release]; } else if(array == nil && isArray){ [arrayForObjs addObject:baseObj]; [baseObj release]; baseObj = nil; [propertyNames release]; [propertyDic release]; } if (iret != nil) { //[iret release]; } } if (array == nil) { [propertyNames release]; [propertyDic release]; } if (i!=0 && !isArray) { index++; } //处理新加节点用这个实体却没有新加节点的情况 if (i==0) { for (NSString* keystr in propertyBase) { if ([[propertyDicBase objectForKey:keystr] isEqualToString:@"NSString"]) { if([baseObj valueForKey:keystr]==nil){ index++; } } } } for (NSString* keystr in propertyBase) { if(((index-1) == [propertyBase indexOfObject:keystr]) && i!=0 && ![[propertyDicBase objectForKey:keystr] isEqualToString:@"NSString"]){ if ([[propertyDicBase objectForKey:keystr] isEqualToString:@"NSMutableArray"]) { [baseObj setValue:array forKey:keystr]; [array release]; array = nil; } else { [baseObj setValue:obj forKey:keystr]; } } else if(((index+1) == [propertyBase indexOfObject:keystr]) && i!=0 && ![[propertyDicBase objectForKey:keystr] isEqualToString:@"NSString"]){ [baseObj setValue:obj forKey:keystr]; } } [obj release]; obj = nil; } [propertyBase release]; [propertyDicBase release]; [doc release]; if (isArray) { if (baseObj!= nil) { [baseObj release]; } return [arrayForObjs autorelease]; } else{ return [baseObj autorelease]; } }
json解析：
ESJsonFormat和Json model的配合使用自动生成model爽翻天
生成model示例：
@class ComplaintlistItem; @interface AppealListModel : NSObject @property (nonatomic, assign) NSInteger IsSuccess; @property (nonatomic, assign) NSInteger RecordCount; @property (nonatomic, copy) NSString *ErrorMessage; @property (nonatomic, strong) NSArray<ComplaintlistItem *> *ComplaintList; @end @interface ComplaintlistItem : NSObject @property (nonatomic, copy) NSString *OrderID; @property (nonatomic, copy) NSString *YzName; @property (nonatomic, copy) NSString *ComplaintStateName; @property (nonatomic, assign) NSInteger ComplaintID; @property (nonatomic, assign) NSInteger Frequency; @property (nonatomic, copy) NSString *Content; @property (nonatomic, assign) NSInteger ComplaintState; @property (nonatomic, copy) NSString *CreateTime; @end
实现：
@implementation AppealListModel + (NSDictionary *)objectClassInArray{ return @{@"ComplaintList" : [ComplaintlistItem class]}; //上层的属性，和其对应的model类的一一对应字典，如果多层嵌套，在相应的上层类实现文件中这样指明解析对应关系即可 } @end @implementation ComplaintlistItem @end
