iOS changes the Uitextfield frame inside the Uisearchbar and removes the Uisearchbar background

1, custom Uisearchbar subclass Mysearchbar, rewrite Layoutsubviews method.

Code:

-(void) layoutsubviews {
	[super layoutsubviews];
	
	For (UIView *view in self.subviews)
	{
		if ([View iskindofclass:nsclassfromstring (@ "UIView")] && View.subviews.count > 0) {for
			(UIView *subview in view.subviews) {
				if (Subview iskindofclass: Nsclassfromstring (@ "Uitextfield")]) {
					Uitextfield *textfield = (Uitextfield *) Subview;
					CGRect frame = textfield.frame;
					Frame.size.height =;
					Textfield.frame = frame;
					Textfield.font = [Uifont fontwithname:@ "Helvetica" size:17.0f];
					break;
				}
			}
			break;
		}}}

2, if the Uisearchbar is defined in a xib file, do the following in the Awakefromnib method:

	For (UIView *view in self.destinationSearchBar.subviews)
	{
		if ([View iskindofclass:nsclassfromstring (@) UIView ")] && view.subviews.count > 0) {
			[[view.subviews objectatindex:0] removefromsuperview];
			
			CGRect frame = view.frame;
			CGFloat height = frame.size.height + 8;
			frame.size.height = height;
			View.frame = frame;
			View.clipstobounds = NO;
			break;
		}
	}

If it is generated using the Alloc/init method, add the code in its corresponding Uviewcontroller Viewdidload method
