无法在NSObject Xcode中使用UIView

Question

#import <Foundation/Foundation.h>

typedef enum _NSBubbleType
{
BubbleTypeMine = 0,
BubbleTypeSomeoneElse = 1
} NSBubbleType;

@interface NSBubbleData : NSObject

@property (readonly, nonatomic, strong) NSDate *date;
@property (readonly, nonatomic) NSBubbleType type;
@property (readonly, nonatomic, strong) UIView *view;
@property (readonly, nonatomic) UIEdgeInsets insets;
@property (nonatomic, strong) UIImage *avatar;

- (id)initWithText:(NSString *)text date:(NSDate *)date type:      (NSBubbleType)type;
+ (id)dataWithText:(NSString *)text date:(NSDate *)date type:(NSBubbleType)type;
- (id)initWithImage:(UIImage *)image date:(NSDate *)date type:(NSBubbleType)type;
+ (id)dataWithImage:(UIImage *)image date:(NSDate *)date type: (NSBubbleType)type;
- (id)initWithView:(UIView *)view date:(NSDate *)date type:(NSBubbleType)type insets:(UIEdgeInsets)insets;
+ (id)dataWithView:(UIView *)view date:(NSDate *)date type:(NSBubbleType)type insets:(UIEdgeInsets)insets;

下面是我的对象和.m类     #import“NSBubble.h”     #import

@implementation NSBubble

@synthesize datee,vieww,insetss,typee;

#pragma mark - Text bubble

const UIEdgeInsets textInsetsMine = {5, 10, 11, 17};
const UIEdgeInsets textInsetsSomeone = {5, 15, 11, 10};

+ (id)dataWithText:(NSString *)text date:(NSDate *)date type:(NSBubbleType)type
{
    return [[NSBubble alloc] initWithText:text date:date type:type];
}

- (id)initWithText:(NSString *)text date:(NSDate *)date type:(NSBubbleType)type
{
UIFont *font = [UIFont systemFontOfSize:[UIFont systemFontSize]];
CGSize size = [(text ? text : @"") sizeWithFont:font constrainedToSize:CGSizeMake(220, 9999) lineBreakMode:NSLineBreakByWordWrapping];

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, size.width, size.height)];
label.numberOfLines = 0;
label.lineBreakMode = NSLineBreakByWordWrapping;
label.text = (text ? text : @"");
label.font = font;
label.backgroundColor = [UIColor clearColor];

UIEdgeInsets insets = (type == BubbleTypeMine ? textInsetsMine : textInsetsSomeone);
return [self initWithView:label date:date type:type insets:insets];
}


#pragma mark - Custom view bubble

+ (id)dataWithView:(UIView *)view date:(NSDate *)date type:(NSBubbleType)type insets:(UIEdgeInsets)insets
{
return [[NSBubble alloc] initWithView:view date:date type:type insets:insets];
}

- (id)initWithView:(UIView *)view date:(NSDate *)date type:(NSBubbleType)type insets:(UIEdgeInsets)insets
{
self = [super init];
if (self)
{

    vieww = view;
    datee = date;

    typee = type;
    insetss = insets;
}
return self;
}

这是我的表格视图

在运行项目时显示多个。它似乎是出乎意料的。帮助将是必须赞赏的。他们可能是tableview及其数据源的一些问题我认为我理解我如何用这个url实现这个url有人帮助。

Answer 1

您需要导入<UIKit/UIKit.h>。它添加了必要的UIImage，UITableView，UIView等。

正如您所看到的，此错误： UITableView数据源未设置表示您未设置表视图数据源。您必须在接口构建器中将表视图与数据源连接。
