[英]Setting background color of grouped UITableViewCell
我有一個分組的UITableView
。 我試圖做一個自定義的UITableViewCell
背景:
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
self.contentView.opaque = YES;
self.contentView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"rowbg@2x"]];
//Change Indicator
CGRect rect;
rect = CGRectMake(0, 0, 10, 50);
changeImageIndicator = [[UIImageView alloc] initWithFrame:rect];
[self.contentView addSubview: changeImageIndicator];
//Symbol
rect = CGRectMake(10, 10, 200, 20);
symbolLabel = [[UILabel alloc] initWithFrame:rect];
symbolLabel.textAlignment = UITextAlignmentLeft;
symbolLabel.font = [UIFont fontWithName:@"Arial" size:22];
symbolLabel.textColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:1.0];
symbolLabel.backgroundColor = [UIColor clearColor];
[self.contentView addSubview: symbolLabel];
//Company
rect = CGRectMake(10, 30, 180, 20);
companyLabel = [[UILabel alloc] initWithFrame:rect];
companyLabel.textAlignment = UITextAlignmentLeft;
companyLabel.font = [UIFont fontWithName:@"Arial" size:13];
companyLabel.adjustsFontSizeToFitWidth = YES;
companyLabel.minimumFontSize = 10.0;
companyLabel.backgroundColor = [UIColor clearColor];
companyLabel.textColor = [UIColor colorWithRed:118.0/255.0 green:118.0/255.0 blue:118.0/255.0 alpha:1.0];
[self.contentView addSubview: companyLabel];
//Price
rect = CGRectMake(190, 10, 100, 20);
priceLabel = [[UILabel alloc] initWithFrame:rect];
priceLabel.textAlignment = UITextAlignmentRight;
priceLabel.font = [UIFont fontWithName:@"Arial" size:20];
priceLabel.textColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:1.0];
priceLabel.backgroundColor = [UIColor clearColor];
[self.contentView addSubview: priceLabel];
//Change
rect = CGRectMake(190, 30, 100, 20);
changeLabel = [[UILabel alloc] initWithFrame:rect];
changeLabel.textAlignment = UITextAlignmentRight;
changeLabel.font = [UIFont fontWithName:@"Arial" size:15];
changeLabel.textColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:1.0];
changeLabel.adjustsFontSizeToFitWidth = YES;
changeLabel.backgroundColor = [UIColor clearColor];
changeLabel.minimumFontSize = 10.0; //adjust to preference obviously
[self.contentView addSubview: changeLabel];
}
return self;
}
背景顏色流過圓角。 見圖片:
我怎樣才能使它不流血?
這適用於iOS 3.0及更高版本:
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
cell.backgroundColor = [UIColor redColor];
}
那么self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
?
在tableView:cellForRowAtIndexPath中設置單元格背景色:
cell.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"Gradient.png"]];
當沒有其他事情時,這對我有用。 將IB中的背景顏色設置為分組的表格視圖顏色(默認)。 然后在代碼中,將顏色設置為clearColor。 我也將單元格標記為opaque = NO和clearsContextBeforeDrawing = NO,但是這些設置本身並沒有改變任何東西,直到我通過代碼添加了clearColor – Bdebeez
self.contentView.superview.opaque = YES; self.contentView.superview.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@“ rowbg @ 2x”]];
您是否嘗試過設置backgroundView的backgroundColor而不是contentView?
我必須創建一個圓形的頂部,中間和按鈕圖形圖像,並根據它所在的行將其設置為單元格的背景視圖。
