效果如图：-------->

-(CGRect)editingRectForBounds:(CGRect)bounds；

@interfaceMYTextField:UITextField

@end


@implementationMYTextField

-(CGRect)textRectForBounds:(CGRect)bounds {
    int margin =10;
    CGRect inset =CGRectMake(bounds.origin.x + margin, bounds.origin.y, bounds.size.width - margin, bounds.size.height);
    return inset;
}

-(CGRect)editingRectForBounds:(CGRect)bounds {
    int margin =10;
    CGRect inset =CGRectMake(bounds.origin.x + margin, bounds.origin.y, bounds.size.width - margin, bounds.size.height);
    return inset;
}
