局部声明隐藏实例变量警告

本地声明隐藏“self.treatmentId =treatmentId;”附近的实例变量消息弹出窗口和“self.treatmentName =treatmentName;”;

@implementation Treatment

@synthesize treatmentId;
@synthesize treatmentName;

-(Treatment *)initWithtreatmentName:(NSString *)treatmentName treatmentId:(NSString *)treatmentId{


    if((self = [super init])){
        self.treatmentId = treatmentId;
        self.treatmentName = treatmentName;
    }

    return self;

 }

@end

将您的代码更改为以下内容。

@implementation Treatment

@synthesize treatmentId;
@synthesize treatmentName;

-(Treatment *)initWithtreatmentName:(NSString *)newTreatmentName treatmentId:(NSString  *)newTreatmentId{


    if((self = [super init])){
        self.treatmentId = newTreatmentId;
        self.treatmentName = newTreatmentName;
    }

    return self;

 }

@end

通过声明局部变量trentmentName and treatmentId您基本上失去了通过名称访问全局（iVar）的能力。
