tableViewCell cell 圖片大小的設置

1.經過設置 圖形上下文 

1 2 3 4 5 6 7 8

CGSize itemSize = CGSizeMake(40, 40);   UIGraphicsBeginImageContext(itemSize); CGRect imageRect = CGRectMake(0.0, 0.0, itemSize.width, itemSize.height); [cell.imageView.image drawInRect:imageRect];   cell.imageView.image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext();

2. 只有在UITableViewCell子類中重寫layoutSubviews方法去改變這些值，舉例

-(void)layoutSubviews 

{ 

[super layoutSubviews];

[self.imageView setFrame:CGRectMake(10, 10,29, 29)];

self.imageView.contentMode = UIViewContentModeScaleAspectFit;

}
