@ end
@ implementation XXTableiewCell
+ (instancetype) cellWithTableView: (UITableView *) tableView {
Static NSString * cellID = @ "cellId"
XXTableiewCell * cell = [[XXTableiewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID]
Return cell
}
-(id) initWithStyle: (UITableViewCellStyle) style reuseIdentifier: (NSString *) reuseIdentifier {
Self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]
If (self) {
[self setViewUI]
}
Return self
}
-(void) setViewUI {
_ titleLabel = [[UILabel alloc] init]
_ titleLabel.font = [UIFont systemFontOfSize:XXTableiewCell_fontSize]

}
-(void) layoutSubviews {
