Question

所以我有一个自定义TVShow对象，它有一些基本字段，如id，showName，airDate等，它们都是NSStrings或NSIntegers，我试图通过我从API获得的一些数据创建一堆这些对象在线。

所以我遍历我的NSArray的JSON数据并为每个响应创建一个TVShow对象：

TVShow *show = [[TVShow alloc] initWithData:[NSJSONSerialization JSONObjectWithData:data options:0 error:&error]];
[self.showArray addObject:show];

但是，只创建了其中的7个，然后下面的任何代码都停止运行。我有一个NSLog（@＆＃34;已添加＆＃34;）;在我创建节目后打印，它只被调用6次。如果我在任何代码之后添加断点，它们永远不会被调用。我不知道发生了什么，但它必须与我如何设置我的TVShow对象有关？

目前看起来像：

#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>

@interface TVShow : NSObject

@property NSInteger showID;
@property NSString *showName;
@property NSString *airDate;
@property double rating;
@property NSString *imageUrl;
@property NSString *showSummary;
@property NSString *episodeSummary;
@property NSInteger season;
@property NSInteger episode;

- (id)initWithData:(NSDictionary *)data;

@end

和.m文件：

#import <UIKit/UIKit.h>
#import "TVShow.h"

@implementation TVShow

- (id)initWithData:(NSDictionary*)data {
    self = [super init];
    if(self) {

        [self buildObjectFromData:data];
    }
    return self;
}
-(void)buildObjectFromData:(NSDictionary*)data {
    NSDictionary *dict = [data objectForKey:@"_embedded"];
    NSDictionary *dict2 = [dict objectForKey:@"nextepisode"];
    NSDictionary *dict3 = [data objectForKey:@"image"];

    NSString *airDate = [dict2 valueForKey:@"airstamp"];
    NSInteger season = [[dict2 valueForKey:@"season"] integerValue];
    NSInteger episode = [[dict2 valueForKey:@"episode"] integerValue];
    NSString *episodeSummary = [dict2 valueForKey:@"summary"];
    NSString *showName = [data valueForKey:@"name"];
    NSString *showSummary = [data valueForKey:@"summary"];
    NSString *imageUrl = [dict3 valueForKey:@"medium"];
    NSInteger showID = [[data valueForKey:@"id"] integerValue];

    self.airDate = airDate;
    self.showName = showName;
    self.season = season;
    self.episode = episode;
    self.showSummary = [self stringByStrippingHTML:showSummary];
    self.episodeSummary = [self stringByStrippingHTML:episodeSummary];
    self.imageUrl = imageUrl;
    self.showID = showID;
}

-(NSString *) stringByStrippingHTML:(NSString*)string {
    NSRange r;
    NSString *s = string;
    while ((r = [s rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
        s = [s stringByReplacingCharactersInRange:r withString:@""];
    return s;
}

@end

如果我将对象创建为：[[TVShow alloc] init];一切正常，所以这个模型一定是错的是我所想的。我不确定下一步该尝试什么，但是在这里会非常感谢任何帮助。

原来有些案例已经出现：

-(NSString *) stringByStrippingHTML:(NSString*)string {
    NSRange r;
    NSString *s = string;
    while ((r = [s rangeOfString:@"<[^>]+>" options:NSRegularExpressionSearch]).location != NSNotFound)
        s = [s stringByReplacingCharactersInRange:r withString:@""];
    return s;
}

进入无限循环。删除此代码段会修复冻结。
