若是須要更改默認的UITextField清除按鈕、左右視圖等等控件的位置,能夠經過以下設置:字體
// 控制清除按鈕的位置 (默認 width = 15 = height) -(CGRect)clearButtonRectForBounds:(CGRect)bounds { // NSLog(@"=%f ,=%f",bounds.origin.y,bounds.size.height/2); return CGRectMake(bounds.origin.x + bounds.size.width - 50, (bounds.size.height - 15)/2, 15, 15); } // 控制placeHolder的位置 默認(0,0,width,height) -(CGRect)placeholderRectForBounds:(CGRect)bounds { // return CGRectInset(bounds, 20, 0); CGRect inset = CGRectMake(bounds.origin.x + 50, bounds.origin.y, bounds.size.width - 10, bounds.size.height); return inset; } // 控制顯示文本的位置 默認(0,0,width,height) -(CGRect)textRectForBounds:(CGRect)bounds { NSLog(@"顯示文本==%@",NSStringFromCGRect(bounds)); //return CGRectInset(bounds, 50, 0); CGRect inset = CGRectMake(bounds.origin.x + 190, bounds.origin.y, bounds.size.width - 10, bounds.size.height); return inset; } // 控制編輯文本的位置 -(CGRect)editingRectForBounds:(CGRect)bounds { NSLog(@"編輯文本==%@",NSStringFromCGRect(bounds)); //return CGRectInset( bounds, 10 , 0 ); CGRect inset = CGRectMake(bounds.origin.x + 100, bounds.origin.y, bounds.size.width -10, bounds.size.height); return inset; } // 控制左視圖位置 (默認 width=30) - (CGRect)leftViewRectForBounds:(CGRect)bounds { NSLog(@"左視圖位置==%@",NSStringFromCGRect(bounds)); CGRect inset = CGRectMake(bounds.origin.x + 2, bounds.origin.y, 30, bounds.size.height); return inset; //return CGRectInset(bounds,50,0); } // 控制placeHolder的顏色、字體 - (void)drawPlaceholderInRect:(CGRect)rect { [[self placeholder] drawInRect:rect withAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:20.0f], NSForegroundColorAttributeName:[UIColor darkGrayColor] }]; } // 右視圖的位置 (默認整個 width) - (CGRect)rightViewRectForBounds:(CGRect)bounds { NSLog(@"右視圖位置==%@",NSStringFromCGRect(bounds)); CGRect inset = CGRectMake(bounds.size.width - 30, bounds.origin.y, 30, bounds.size.height); return inset; }
