我试图设置我的 UITableViewCell 的 contentView 的偏移量。但是失败了。如图所示,没有偏移。
对应的代码如下。
我的细胞
#import "MyCell.h"
@implementation MyCell
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
UIView *backGroundView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.bounds.size.width, self.bounds.size.height)];
[backGroundView setBackgroundColor:[UIColor grayColor]];
[self addSubview:backGroundView];
UIView *frontView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.bounds.size.width, self.bounds.size.height)];
[frontView setBackgroundColor:[UIColor greenColor]];
UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.bounds.size.width, self.bounds.size.height)];
myLabel.text = @"My Cell";
myLabel.backgroundColor = [UIColor clearColor];
[myLabel setTextAlignment:UITextAlignmentCenter];
[frontView addSubview:myLabel];
[self.contentView addSubview:frontView];
[self bringSubviewToFront:self.contentView];
}
return self;
}
MyTableViewController.m
#import "MyTableViewController.h"
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"MyCell";
MyCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[MyCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
CGPoint center = cell.center;
center.x = cell.contentView.bounds.size.width/2 - 20;
[cell.contentView setCenter:center];
NSLog(@"origin.x :%f ,y :%f, width :%f, height :%f",cell.contentView.frame.origin.x, cell.contentView.frame.origin.y, cell.contentView.frame.size.width,cell.contentView.frame.size.height);
return cell;
}
