我必须创建一个自定义UICollectionViewCell来显示图像的图像和名称.在图像的顶部,有一个帧图像,其宽度和高度比图像大2个像素.但是,无论我做什么,图像似乎都比帧图像大.我为表格视图做了同样的事情,它完美无缺.
这是代码：
//GridCell.h
@interface GridCell : UICollectionViewCell
@property(nonatomic,strong) UILabel *lblName;
@property(nonatomic,strong) UIImageView *image;
@end
//GridCell.m
#import "GridCell.h"
@implementation GridCell
@synthesize image,lblName;
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
UIImage *bg = [UIImage imageNamed:@"borderUIimgLg.png"];
UIImageView *bgImage = [[UIImageView alloc] initWithFrame:CGRectMake(0.0,0.0,frame.size.width,frame.size.width)];
[bgImage setImage:bg];
[bgImage setContentMode:UIViewContentModeScaleAspectFill];
NSLog(@"BG Image size %f,%f",bgImage.frame.size.width,bgImage.frame.size.height);
UIImageView *contentImage = [[UIImageView alloc] initWithFrame:CGRectMake(2.0,2.0,frame.size.width-4.0,frame.size.width-4.0)];
[contentImage setContentMode:UIViewContentModeScaleAspectFill];
[contentImage setClipsToBounds:YES];
self.image = contentImage;
[self.contentView addSubview:self.image];
[self.contentView addSubview:bgImage];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(2.0,frame.size.width - 4.0,21.0)];
[label setFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:11.0]];
[label setTextAlignment:NSTextAlignmentCenter];
[label setBackgroundColor:[UIColor clearColor]];
self.lblName = label;
[self.contentView addSubview:self.lblName];
}
return self;
}
UICollectionViewCell的大小为67 x 100,因此在代码中,bgImage应始终为67 x 67,其原点为(0,0),而contentImage应为(0,63),63).通过调试,似乎是正确的.但是,conentimage总是比bgImage大.但是图像的原始尺寸为80 x 80.我试过setClipToBounds,
在cell.ContentView或imageView上使用setContentviewmode,但都不起作用.
附上有关该问题的屏幕截图.
任何帮助表示赞赏.
