1、更改textField的clearButton样式
UIButton *clearButton = [_nameTextField valueForKey:@"_clearButton"];
[clearButton setImage:[UIImage imageNamed:@"emotionstore_progresscancelbtn.png"] forState:UIControlStateNormal];
2、更改textField的placehoder的字体颜色
[textField setValue:[UIColor redColor] forKeyPath:@"_placeholderLabel.textColor"];
3、延迟执行
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.5 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
});
4、获取每个tableViewCell中的按钮点击
- (void)clickButton:(UIButton *)button event:(id)event {
NSSet *touches = [event allTouches];
UITouch *touch = [touches anyObject];
CGPoint currentTouchPosition = [touch locationInView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:currentTouchPosition];
if (indexPath != nil) {
}
}
5、更改字符串属性和字体
NSString *string = @"123ABC456";
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:string];
[attributedString addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange:(3,3)];//更改 ABC 字符颜色为红色
[attributedString addAttribute:NSFontAttributeName value:[UIFont boldSystemFontOfSize:15] range:NSMakeRange:(6,3)];//更改 456 字符字体大小为15号字体
6、更改 tableView 分割线颜色和长度
if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {
[self.tableView setSeparatorInset:UIEdgeInsetsMake(0, 20, 0, 20)];
[self.tableView setSeparatorColor:[UIColor colorWithRed:0.89f green:0.89f blue:0.89f alpha:1.00f]];
}
if ([self.tableView respondsToSelector:@selector(setLayoutMargins:)]) {
[self.tableView setLayoutMargins:UIEdgeInsetsMake(0, 20, 0, 20)];
[self.tableView setSeparatorColor:[UIColor colorWithRed:0.89f green:0.89f blue:0.89f alpha:1.00f]];
}
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([cell respondsToSelector:@selector(setSeparatorInset:)]) {
[self.tableView setSeparatorInset:UIEdgeInsetsMake(0, 20, 0, 20)];
[self.tableView setSeparatorColor:[UIColor colorWithRed:0.89f green:0.89f blue:0.89f alpha:1.00f]];
}
if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
[self.tableView setLayoutMargins:UIEdgeInsetsMake(0, 20, 0, 20)];
[self.tableView setSeparatorColor:[UIColor colorWithRed:0.89f green:0.89f blue:0.89f alpha:1.00f]];
}
}
