How to read JSON data of server interface in MVC layer of IOS
This article mainly introduces the IOS MVC layer how to read server interface JSON data, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.
The specific procedures are as follows:
One: YSMasonryManager.h
# import # import "BaseManager.h" # import "YSMasonryModel.h" @ protocol YSMasonryManagerDelegate-(void) networkSuccess: (YSMasonryModel * _ Nullable) result;- (void) networkFail: (NSString * _ Nullable) result;@endNS_ASSUME_NONNULL_BEGIN@interface YSMasonryManager: BaseManager@property (weak,nonatomic) id delegate;- (void) getDeviceProile: (NSString *) limit Offset: (NSString *) offset;@endNS_ASSUME_NONNULL_END
Two: YSMasonryManager.m
# import "YSMasonryManager.h" @ implementation YSMasonryManager- (void) getDeviceProile: (NSString *) limit Offset: (NSString *) offset {NSString * strUrl = [NSString stringWithFormat:@ "% @ api/internal/profile", DEVICE_BASE_URL]; / / JSON [PPNetworkHelper setRequestSerializer:PPRequestSerializerHTTP]; [PPNetworkHelper setResponseSerializer:PPResponseSerializerJSON]; / / configure Jwt file [PPNetworkHelper setValue:USERJWTKEYS forHTTPHeaderField:@ "Grpc-Metadata-Authorization"]; [PPNetworkHelper GET:strUrl parameters:@ "" success: ^ (id responseObject) {YSMasonryModel * net = [YSMasonryModel mj_objectWithKeyValues:responseObject] If (net.organizations.count > 0) {if ([self.delegate respondsToSelector:@selector (networkSuccess:)]) {[self.delegate networkSuccess:net];}} else {if ([self.delegate respondsToSelector:@selector (networkFail:)]) {[self.delegate networkFail:@ "Get Fail!"];} failure: ^ (NSError * error) {/ / NSError * newError = [NSError returnErrorWithError:error] If ([self.delegate respondsToSelector:@selector (networkFail:)]) {[self.delegate networkFail:@ "cc"];}}];} @ end
