1.去掉UISearchbar的邊框線狸窘，改變輸入框背景色
- (void)setSearchBarBackgroundColor: (UIColor *)searchBarBackgroundColor{
_searchBarBackgroundColor =? searchBarBackgroundColor;
for ( UIView*subView in [[self.searchBar.subviews lastObject ]subviews] ) {
if ( [[subViewclass] is SubclassOfClass:[UITextField class]] ) {
UITextField *textField = (UITextField*)subView;
textField.backgroundColor =? searchBarBackgroundColor;
}
if ( [subView isKindOfClass:NSClassFromString(@"UISearchBarBackground")] ) {
[subView removeFromSuperview];
}
}
}
2.給View添加單邊框
- (void)addBorderWithColor: (UIColor*) color frame:(CGRect)frame;
- (void)addBorderWithColor:(UIColor*)color frame:(CGRect)frame {
CALayer *border = [CALayer layer];
border.backgroundColor = color.CGColor;
border.frame = frame;
[self.layer addSublayer:border];
}
3.數(shù)組去重（kvc）
self.xxxArray = [self.xxxArray valueForKeyPath:@"@distinctUnionOfObjects.self"];
4.導(dǎo)航欄透明
- (void)viewWillAppear:(BOOL)animated{
[superview WillAppear:animated];
[[self.navigationController.navigationBarsubviews]objectAtIndex:0].alpha = 0;
}
- (void)viewWillDisappear:(BOOL)animated{
[superview WillDisappear:animated];
[[self.navigationController.navigationBarsubviews]objectAtIndex:0].alpha = 1;
}
5.去掉某個(gè)View的子視圖
[self.xxx.subviewsmakeObjectsPerformSelector:@selector(removeFromSuperview)];
6.UITableViewController修改tableView? Frame
-(void)viewDidLayoutSubviews {
if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {
[self.tableView setSeparatorInset:UIEdgeInsetsZero];
}
if([self.tableView respondsToSelector:@selector(setLayoutMargins:)]){
[self.tableView setLayoutMargins:UIEdgeInsetsZero];
}
[self.tableView setFrame:CGRectMake(0.0,0.0, _width, _height)];
}
7.tableview 初始化無cell線條
self.tableView.tableFooterView= [UIView new];
