借助新的 iOS 7 UIView 色调颜色，可以轻松快速地为整个应用程序设置主题。它甚至在编辑文本字段时更改文本插入符号的颜色。
但是，键盘右下角的“关闭”按钮（可以是“完成”、“搜索”等）始终为蓝色。有什么办法可以改变这个吗？如果它与应用程序其余部分的色调颜色相匹配，它看起来会非常漂亮。
通过一点技巧，也许您可以实现您正在寻找的效果。但它可能无法通过应用程序审核。
-(NSArray*)subviewsOfView:(UIView*)view withType:(NSString*)type{
NSString *prefix = [NSString stringWithFormat:@"<%@",type];
NSMutableArray *subviewArray = [NSMutableArray array];
for (UIView *subview in view.subviews) {
NSArray *tempArray = [self subviewsOfView:subview withType:type];
for (UIView *view in tempArray) {
[subviewArray addObject:view];
}
}
if ([[view description]hasPrefix:prefix]) {
[subviewArray addObject:view];
}
return [NSArray arrayWithArray:subviewArray];
}
-(void)addColorToUIKeyboardButton{
for (UIWindow *keyboardWindow in [[UIApplication sharedApplication] windows]) {
for (UIView *keyboard in [keyboardWindow subviews]) {
for (UIView *view in [self subviewsOfView:keyboard withType:@"UIKBKeyplaneView"]) {
UIView *newView = [[UIView alloc] initWithFrame:[(UIView *)[[self subviewsOfView:keyboard withType:@"UIKBKeyView"] lastObject] frame]];
newView.frame = CGRectMake(newView.frame.origin.x + 2, newView.frame.origin.y + 1, newView.frame.size.width - 4, newView.frame.size.height -3);
[newView setBackgroundColor:[UIColor greenColor]];
newView.layer.cornerRadius = 4;
[view insertSubview:newView belowSubview:((UIView *)[[self subviewsOfView:keyboard withType:@"UIKBKeyView"] lastObject])];
}
}
}
}
