參考網上資料,直接使用網上的代碼,沒有實現,重新修改
YLSTextField文件
#import <UIKit/UIKit.h>
@interface YLSTextField : UITextField
@end
#import "YLSTextField.h"
@implementation YLSTextField
//改變文字位置
-(CGRect) textRectForBounds:(CGRect)bounds{
CGRect iconRect=[super textRectForBounds:bounds];
iconRect.origin.x+=10;
return iconRect;
}
//改變編輯時文字位置
-(CGRect) editingRectForBounds:(CGRect)bounds{
CGRect iconRect=[super editingRectForBounds:bounds];
iconRect.origin.x+=10;
return iconRect;
}
@end
頁面中代碼
self.loginuser.delegate=self;
self.loginpass.delegate=self;
//設置輸入框左邊圖標
UIImageView *image1=[[UIImageView alloc]initWithImage:[UIImage imageNamed:@"user.png"]];
image1.frame=CGRectMake(0, 0, 27, 27);
self.loginuser.leftView=image1;
self.loginuser.leftViewMode=UITextFieldViewModeAlways;
UIImageView *image2=[[UIImageView alloc]initWithImage:[UIImage imageNamed:@"mima.png"]];
image2.frame=CGRectMake(0, 0, 27, 27);
self.loginpass.leftView=image2;
self.loginpass.leftViewMode=UITextFieldViewModeAlways;
輸入框點擊時背景圖改變,不知道爲啥在storyboard中設置的沒有起作用。
//改變輸入框背景圖片
-(void)textFieldDidBeginEditing:(YLSTextField *)textField{
if (textField.tag==3) {
[self.loginuser setBackground:[UIImage imageNamed:@"inputlan.png"]];
}else if(textField.tag==4){
[self.loginpass setBackground:[UIImage imageNamed:@"inputlan.png"]];
}
}
-(void)textFieldDidEndEditing:(YLSTextField *)textField{
if (textField.tag==3) {
[self.loginuser setBackground:[UIImage imageNamed:@"inputhui.png"]];
}else if(textField.tag==4){
[self.loginpass setBackground:[UIImage imageNamed:@"inputhui.png"]];
}
}
