iOS 代碼自定義cell示例
底色標黃為代碼自定義cell重點處，入手從這幾點即可。
MyCell.h
#import
@interface MyCell :UITableViewCell
@property(nonatomic,strong)UILabel *ageLabel;
@property(nonatomic,strong)UILabel *nameLabel;
@property(nonatomic,strong)UILabel *additionLabel;
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier;
@end
MyCell.m
#import MyCell.h
@implementation MyCell
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
if (self = [superinitWithStyle:stylereuseIdentifier:reuseIdentifier]) {
// for (UIView *view in self.contentView.subviews) {
// NSLog(@%@,view);
// [view removeFromSuperview];
// }
_ageLabel = [[UILabelalloc]init];
_nameLabel = [[UILabelalloc]init];
_additionLabel = [[UILabelalloc]init];
_additionLabel.text =@點擊;
[self.contentViewaddSubview:_ageLabel];
[self.contentViewaddSubview:_nameLabel];
[self.contentViewaddSubview:_additionLabel];
self.backgroundColor = [UIColorclearColor];
}
return self;
}
- (void)layoutSubviews
{
[superlayoutSubviews]; //如不調用父類此方法就會導致在使用時出現分隔線位置不正確，主要是因為父類中會調用其分隔線位置調整
self.nameLabel.frame =CGRectMake(0,0,100,44);
self.ageLabel.frame =CGRectMake(100,0,100,44);
self.additionLabel.frame =CGRectMake(0,40,320, 20);
}
@end
