我正在向滾動視圖添加幾個按鈕。我正在用圖像設置按鈕的背景。當你看到輸出時,圖像似乎被拉長了。我想避免這一點。防止在iOS中的滾動視圖中拉伸圖像
所以我已經試過這樣:
創建一個自定義視圖,它處理圖像並做出這一形象固定遠離邊緣。
這樣做是爲了在自動尺寸部分:
我的代碼如下所示:
for (int counter = 0; counter < imageCount; counter++) {
NSString *imageName = [NSString stringWithFormat:@"%@_img0%d.jpg",mRoutePointId,counter+1];
UIImage *infoImage = [UIImage imageNamed:imageName];
GalleryImage *galleryItem = [[GalleryImage alloc] initWithImage:infoImage];
UIButton *infoImageButton = [[UIButton alloc] initWithFrame:CGRectMake(xOffset, 0, infoImagesScrollView.frame.size.width, infoImagesScrollView.frame.size.height)];
infoImageButton.tag = counter;
[infoImageButton setImage:galleryItem.galleryImage forState:UIControlStateNormal];
[infoImageButton setImage:galleryItem.galleryImage forState:UIControlStateHighlighted];
[infoImageButton addTarget:self action:@selector(infoImageButtonClicked:) forControlEvents:UIControlEventTouchUpInside];
[infoImageButton setTitle:[NSString stringWithFormat:@"%@_img0%d.jpg",mRoutePointId,counter+1] forState:UIControlStateApplication];
[infoImagesScrollView addSubview:infoImageButton];
xOffset+=infoImagesScrollView.frame.size.width;
}
CustomView.m
#import "GalleryImage.h"
@implementation GalleryImage
@synthesize galleryImage;
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
}
return self;
}
- (id)initWithImage:(UIImage*) image
{
self = [super init];
if (self) {
// galleryImageView = nil;
galleryImage = image;
}
return self;
}
-(void)awakeFromNib
{
[galleryImageView setImage:galleryImage];
}
需要就如何確保一些指導添加到按鈕時圖像不會伸展。
歡迎其他建議以及..
你能解釋一下嗎? – lakesh
查看UIView'contentMode'下的文檔。 – matt
例如嘗試'galleryImageView.contentMode = UIViewContentModeCenter' – matt
