Question

我有一个问题，我想放一个按钮而不是@“/ n”即，@“uibutton”

BibleIphoneAppDelegate *appDelegate = (BibleIphoneAppDelegate *)[[UIApplication sharedApplication] delegate];
     NSArray *allVerses = [appDelegate.biblearray valueForKey:@"verseNumber"];
    _bibleDesciption.text = [allVerses componentsJoinedByString:@"/n"];

verseNumber包含圣经的经文，我需要在经文之间加一个按钮。我希望你理解我的问题。帮助我做这个。提前谢谢。

我没有对此进行测试，因此可能包含一些错误，但应该可以帮助您入门。

    // set these as members of your class
NSMutableArray *_versesLabels;          // used for easier access when a button is pressed
NSMutableArray *_versesButtons;
/*IBOutlet */UIScrollView *_scrollView;

    // your initialization/loading method
// <..set up _scrollView as you wish>
int labelWidth = 300; // change this as you wish
int buttonWidth = 100, buttonHeight=30;
int padding = 5;      // space between labels/buttons from the scrollView
BibleIphoneAppDelegate *appDelegate = (BibleIphoneAppDelegate *)[[UIApplication sharedApplication] delegate];
NSArray *allVerses = [appDelegate.biblearray valueForKey:@"verseNumber"];
int currentY = padding;
for(int i=0; i<[allVerses count]; i++){
        // create and place the label
    UILabel *lbl = [[UILabel alloc] init];
    lbl.text = [allVerses objectAtIndex:i];
    // <..customize the label - fonts, colors etc>
    lbl.numberOfLines = 0;  // in case you have verses that don't fit in a single line
    CGSize size = [lbl.text sizeWithFont:lbl.font constrainedToSize:CGSizeMake(labelWidth, 500)];
    lbl.frame = CGRectMake(0, currentY, labelWidth, size.height);
    [_scrollView addSubView:lbl];
    [_versesLabels addObject:lbl];
    [lbl release];
    currentY=currentY + lbl.frame.size.height + padding;
        // create and place the button
    UIButton *btn = [[UIButton alloc] initWithFrame:CGRectMake(0, currentY, buttonWidth, buttonHeight)];
    btn.tag = i;
    // <..customize the button - fonts, colors etc>
    [btn addTarget:self action:@selector(pressVerse:) event:UIEventTouchUpInside];
    [_scrollView addSubView:btn];
    [_versesButtons addObject:btn];
    [btn release];
    currentY=currentY + btn.frame.size.height + padding;
}
[_scrollView setContentSize:CGSizeMake(_scrollView.frame.size.width, currentY)];


-(void)pressVerse:(UIButton *)b{
    verseIndex = b.tag;
    UILabel *verseLabel = [_verseLabels objectAtIndex:verseIndex];
    // <..do whatever you want when a button is pressed>
}

在componentsJoinedByString中显示按钮
